Emulation of Playstation 2 is currently handled by 3 kind of emulators. CECH-A/B models use ps2_emu.self able to use built-in PS2 hardware (EE/GS/Rambus memory), and have best compatibility. CECH-C/E use ps2_gxemu, this emulator use physical Graphic Synthesizer found in this ps3 model, but Emotion Engine is fully emulated here, also there is no Rambus memory. All other models emulate PS2 thru fully software based ps2_netemu used for ps2 classics, and hacked now to use decrypted ISO files. Earlier before Sony provided ps2 classics on PS Store there was another soft only emulator strongly based on ps2_gxemu. It was called ps2_softemu, and had support for original PS2 CDVD. Only emulator not able to run physical discs is ps2_netemu.

Emulators are self files, but not typical one. Emulators are not truly PS3 Game OS elf executables, but Guest OS'es running on LV1 of PS3. This mean that LV2, or more friendly Game OS is unloaded before emulator is loaded. This also mean that while emulators are running we can't call any LV2 function. Also LV1 syscalls are limited to call from all emulators, but can be fully unlocked.

All emulators use built-in stripped developement version of PS2 BIOS with disabled debug functions that can affect some games. This is done because some games print debug info on screen when found that are run on dev bios. Bios between ps2_emu, and ps2_gxemu/ps2_netemu are different. Ps2_emu BIOS is able to run only on ps2emu version of emulator due to RDRAM check.

This is done because some games print debug info on screen when found that are run on dev bios. Bios between ps2_emu, ps2_gxemu, and ps2_netemu are different. Although bios from gxemu run fine on netemu, and vice-versa. While ps2_emu BIOS is able to run only on ps2emu version of emulator.      
PS3 models without Emotion Engine unit use "SPE-compatible SIMD graphics-rounding mode for VMX/Altivec Instructions" for FPU, and VU0 emulated floats calculations. This is set on emulator init by HV call 97 with param 1. VU1 actually run at SPE core so no compatibility mode need (or can) to be set. SPE compatible mode for PPE mean that rounding mode is set as round to zero, denormals are treated as zero, and there are no infinities or NaNs. So theoretically what PS2 FPU/VU was originally. Although SPE and PPE SPE compatibility mode is still inaccurate comparing to PS2, because Sony decided to cut off 2 guard bits from calculations on PS2. Probably because there was no need for round and sticky bits (no Nan/Inf, one round mode, etc.). Additionally float divide algorithm is custom and not fully understood up to this day. Good example here are TriAce games, or Castlevania COD where SPE calculation is wrong by 1 bit making games unplayable without patch. This are PS2 math algo specific inaccuracies in FPU/VU implementation that are not present on any other hardware.

=== Memory Allocation ===
==General observations regarding PS2 Classics emulator (ps2_netemu)==
* Virtual memory cards are per title based, but apparently run through the current memory card system. The module used to manage memory cards is: vmc_savedata_plugin.sprx - Using a regular memory card that has been renamed result in a "The save data is corrupt (8XXXXXXX) error"
* Loads an epilepsy warning before PS2 logo (PS button menu appears during epilepsy warning if controller is synced)
* Does not support online functionality of PS2 titles (network configuration utility inside Full Spectrum Warrior claims no network adaptor has been found, same with Syphon Filter: The Omega Strain).


{| class="wikitable"
- Only file that is needed in the folder for PS2 Classics is "iso.bin.enc". Removing the manuals/DXT files will cause the game to boot IMMEDIATELY to the PS2 logo upon switching to 720p/starting PS2 LPAR.
 
===LIMG Segment===
The ISO.BIN.ENC has a block of 0x4000 bytes added at the end codenamed "LIMG" that works as a descriptor for the ISO structure

===BIOS===
====SPE local storage====
====ps2_netemu.self====
Emulator access SPE LS by accessing special addresses. Mapping as follows:
Ps2_netemu use integrated PS2 bios included in ps2netemu.elf, not additional file like in ps1emu case. In 4.81 firmware BIOS is located from 0x820A00 to 0x9F09FF (0x820900 to 0x9F08FF in fw4.50). Bios version seems to be Developement v2.20 from Japan region (22/01/2007), but it's of course not limited to booting only NTSC-J games.
{| class="wikitable"
 
Notable thing is that ps2_netemu run fine with ps2_gxemu bios (gxemu bios have much better support for peripherals). Is very promising for adding USB support for Buzz controllers, Eyetoy, and other peripherals.

===ps2_netemu.self===
Support for USB devices seems to be limited comparing to other available emulators. Although PS2 side of USB subsystem seems to be fully implemented. IOP emulator in SPU handle USB HW registers addresses and generate interrupt for PPU which later handle RW to mentioned registers in similar fashion to ps2_emu/ps2_gxemu. PS2 side of things can be disabled/enabled using one byte, when disabled USB writes are ignored, and USB reads return 0. Initial state is unknown. Emulator seems to accept HID controllers and use them as DS3.
<br/><br/>
Supported devices:
#BD Remote Control
#PLAYSTATION(R)3 Controller (Vendor ID 0x54C, Product ID 0x268),
#Motion Controller - Move (Vendor ID 0x54C, Product ID 0x3D5),
#Navigation Controller  (Vendor ID 0x54C, Product ID 0x42F)
#"guncon3"
<br/>
Unknown:
#Vendor ID 0xF0D (Hori), Product ID 0x4A
#Vendor ID 0x54C (Sony), Product ID 0x5AF
<br/>
Few peripherals not listed above work fine or with issues.
#PS3 Dance Dance Revolution Dance Pad - not ps2 accessory, opposite arrows can't be pressed at the same time.
#Pop'N Music controllers - Require PS2 to USB converter. Wrong button mappings can be fixed by remap in config file.
#Retro-Bit Official SEGA Mega Drive USB 6-Button Controller. Mapped for PS3 already and also works with this emulator. Lacks analogue sticks and shoulder buttons.
 
==BIOS==
===ps2_netemu.self===
Ps2_netemu use integrated PS2 bios included in ps2netemu.elf, not additional file like in ps1_emu. In 4.81 firmware BIOS is located from 0x820A00 to 0x9F09FF (0x820900 to 0x9F08FF in fw4.50). Bios version is Developement v2.20 (22/01/2007).
 
Notable thing is that ps2_netemu use the same bios as ps2_gxemu, and ps2onps4. ps2_netemu not boot using ps2_emu bios because of failing RDRAM check.

==Virtual PS2 HDD==
| PS1VERJ || 0x861950 || 0x40F50 ||  || BIN
There are 2 different "PS2 game" contents that can be installed in PS3 HDD (CATEGORY's [[PARAM.SFO#CATEGORY_For_HDD_contents | 2P and 2G ]]).
|-
'''2P''' are games released from PSN as "PS2 Classic" in .PKG format, and '''2G''' are a few real "PS2 DVD discs" that can be installed in the PS3 HDD, this installation is managed by the '''PS2_system_data.pkg'''.
| PS1VERA || 0x861960 || 0x40F60 ||  || BIN
 
|-
This games can be installed in real PS2 (in the internall HDD of a PS2 fat)... later this same installation was used in the [http://en.wikipedia.org/wiki/PSX_(DVR) PSX]... and when implemented in PS3 there was needed to use a '''virtual PS2 HDD''' image file keeping the same format than the original HDD used in PS2.
| PS1VERE || 0x861970 || 0x40F70 ||  || BIN
 
|-
Game files (extracted from the real PS2 disc) are installed in a '''IMAGE.DAT''' file, this file is a 1:1 "raw copy" of a PS2 HDD.
| PS1VERC || 0x861980 || 0x40F80 ||  || BIN
 
|-
This '''IMAGE.DAT''' is placed in the "install folder" (inside USRDIR folder) and his size can vary up to 10+GB
| PS1VERH || 0x861990 || 0x40F90 ||  || BIN
 
|-
There are 2 different installations: the most common is used to store "game expansions" (e.g: used by additional content in SOCOM games)... the other type of installation is a "full install" and it seems the only game that uses it is "Final Fantasy XI" (main game installation when the game boots for first time + game expansions added later when needed in the same '''IMAGE.DAT''')
| OSDSYS || 0x8619A0 || 0x40FA0 || The browser || BIN
 
|-
'''PS2_system_data.pkg''' itself uses an '''IMAGE.DAT''' file (6.43 MB)
| - || 0x8619B0 || 0x40FB0 ||  || BIN
 
|-
The structure of this "virtual PS2 HDD" uses an "APA header" and a "APA MBR" + several "APA partitions", some of them containing "PFS filesystems".
| RDRAM || 0x861A00 || 0x41000 || Provides a RDRAM test for the EE at power-on. This is run from RESET. || BIN

any chance of having this package resigned for 4.21 cfw? might be useful to see if it'll boot ps2_netemu.self LPAR.
==Emulators management from GameOS==
 
===Mountpoints===
  dev_ps2disc
  dev_ps2disc1


(can boot ps2lpar, but also petitboot if otheros installed! 50:50 chance)
===ps2_netemu syscalls ===
Vector at 0xC00 address.
0x00 -
      0 = return ((unk from 0x1C30/0x1C38 << 56) | thread_number << 48 | ctrl_CT1 (in bit 30) | srr1_EE (in bit 15) | srr1_PS (in bit 14) | srr1_DR (in bit 4))
          Where 0x1C30/0x1C38 is selected depending on current HW thread.
          Thread number is current SW thread
          ctrl_CT1 is lower bit of CT (Current Thread) from PPC Control Register (0 for HW0, 1 for HW1)
          srr1_EE is MSR Enable External Interrupts bit from time when exception occurred (from before syscall was executed)
          srr1_PS is MSR Problem State bit from time when exception occurred (from before syscall was executed)
          srr1_DR is MSR Data Relocate bit from time when exception occurred (from before syscall was executed)
      1 = 0x132 lv1 panic
      2 = 0x133 lv1 panic
      3 = 0x134 lv1 panic
      4 = 0x135 lv1 panic
      else = 0x136 lv1 panic
0x02 - Destroy init code and perform illegal instructions check. Memzero following addresses:
      CODE: 0x16000 - 0x20B80
      DATA: 0x930F80 - 0x933F80
      UNK:  0x3D016000 - 0x3D020B80
0x03 - Enable additional code related to VU0/COP2.
      3 = Patch 0x186C10 to NOP
      4 = Patch 0x186C40 to NOP
      anything else = LV1 panic
0x04 - Unknown. Available for HW0 only.
0x05 - External interrupts disable (48 bit in MSR). Returns previous MSR state.
0x06 - External interrupts enable (48 bit in MSR) if param & 0x8000 is not 0, otherwise disable them.
      This sc is more like restore 48th bit of MSR, but many times emu use it to enable bit without using old state.
      Also, emulator panic LV1 if syscall is called while external interrupts are already enabled.
0x0A - IPU emulation related syscall
0x0B - IPU emulation related syscall
0x0C - Used in PS2 COP0 MTC0/MFC0 r9/r25 (count/perf), decrementer/timing related, return value in r15.
        Config CMD 0x17 disable that syscall for r9 (count) r/w, and alternative path is used. Perf r/w still use it.
0x0E - PS2 counters/timers related (also used on vsync related functions).
0x0F - PS2 counters/timers related (also used on vsync related functions).
0x10 - lv1 panic.
0x11 - Wrapper for lv1_read_virtual_uart(port_number, buffer, bytes) [HW0 only, only ports 0 and 2 available, else panic]
0x12 - Wrapper for lv1_storage_send_device_command(dev_id, cmd_id, cmd_block, cmd_size, data_buffer, blocks)
      [HW0 only, Available only for threads: VRC, MECHA, HDD, else panic]
      params are rearranged:
      r3 = cmd_block (0x245E000 is added to this value internally)
      r4 = data_buffer (0x245E000 is added to this value internally)
      r5 = blocks
      dev_id is taken from 0x245D008 and it is 0(HDD) for my dump.
      cmd_id = 0x88 and cmd_size is 8.
0x13 - Set thread info unknown byte to 1 for respective thread and set unknown byte to 1 in USB thread.
      [HW0 only, else panic. Available only for threads: BL2MAIN and BL2LNK, else do nothing in exception handler]
0x14 - Same as 0x13 but set all bits to 0 regardless which thread called it.
      [HW0 only, else panic. Available only for threads: BL2MAIN and BL2LNK, else do nothing in exception handler]
0x1002 - Invalidate gpu hvcalls.
0x800000XX - HV Syscall where XX is syscall nr.
else (other syscalls) - jump to 0x12670 (FW4.78 - current) for HW_0
                        jump to 0x12050 (FW4.78 - current) for HW_1

0x80000045 - [[HV_Syscall_Reference#lv1_get_logical_ppe_id]]
==Game CONFIG==
0x80000049 - [[HV_Syscall_Reference#lv1_set_interrupt_mask]]
Some of the PS2 emulator types (such ps2_gxemu.self, ps2netemu.self) are able to load config commands that are applyed "by game ID". The concept of "game patches" is not technically correct because some of the commands does patching functions but others does other things (not patching), and other commands works as switches or sets a value that are enviromental settings for the emulator (not for the game) but because are applyed "by game" should be considered enviromental settings for that specific game, so for simplification purposes you can think in all this data as "game configs"
0x8000004A - [[HV_Syscall_Reference#lv1_get_logical_partition_id]]
 
0x8000004E - [[HV_Syscall_Reference#lv1_get_spe_irq_outlet]]
This "game config" data seems to work in the same way for all the PS2 emulator types but can be located in different places, some are hardcoded inside the emulators itself (inside the .self), and at the time the "PS2 classics" emulator (ps2_netemu.self) was developed this config can be loaded from an external file<!--and there is some more inside some .sprx or inside the ps2 hdd data pkg ?-->
0x8000005B - [[HV_Syscall_Reference#lv1_get_repository_node_value]]
 
0x8000005F - [[HV_Syscall_Reference#lv1_read_htab_entries]]
In short, the "game configs" can modify the game image (by patching it) and can be used to configure the virtual PS2 (the emulated machine). And can be loaded from hardcoded data (inside the .self) or from an external file (this feature is supported only by ps2_netemu.self)
0x80000061 - [[HV_Syscall_Reference#lv1_set_vmx_graphics_mode]]
 
0x80000062 - [[HV_Syscall_Reference#lv1_set_thread_switch_control_register]]
The config data consists in a list of concatenated values of 8 bytes lenght (uint32_t), and can be processed like this:
0x80000074 - [[HV_Syscall_Reference#lv1_allocate_io_segment]]
  union{
0x80000076 - [[HV_Syscall_Reference#lv1_allocate_ioid]]
  uint32_t command
0x80000078 - [[HV_Syscall_Reference#lv1_construct_io_irq_outlet]]
  ...data...
0x8000007C - [[HV_Syscall_Reference#lv1_undocumented_function_124]]
  }
0x8000007D - [[HV_Syscall_Reference#lv1_undocumented_function_125]]
 
0x8000007E - [[HV_Syscall_Reference#lv1_undocumented_function_126]]
===Config Commands===
0x80000088 - [[HV_Syscall_Reference#lv1_undocumented_function_136]]
  ps2_netemu.self fw4.50 sub_12D7D8, fw4.81 sub_12E050
0x8000008C - [[HV_Syscall_Reference#lv1_construct_lpm]]
  params are uint32_t unless noted.
  0x8000008D - [[HV_Syscall_Reference#lv1_destruct_lpm]]
 
0x8000008E - [[HV_Syscall_Reference#lv1_start_lpm]]

==Game CONFIG==
|0x19 ||
Some of the PS2 emulator types (such ps2_gxemu.self, ps2netemu.self) are able to load config commands that are applyed "by game ID". The concept of "game patches" is not technically correct because some of the commands does patching functions but others does other things (not patching), and other commands works as switches or sets a value that are enviromental settings for the emulator (not for the game) but because are applyed "by game" should be considered enviromental settings for that specific game, so for simplification purposes you can think in all this data as "game configs"
|-
 
|0x1A ||
This "game config" data seems to work in the same way for all the PS2 emulator types but can be located in different places, some are hardcoded inside the emulators itself (inside the .self), and at the time the "PS2 classics" emulator (ps2_netemu.self) was developed this config can be loaded from an external file<!--and there is some more inside some .sprx or inside the ps2 hdd data pkg ?-->

In short, the "game configs" can modify the game image (by patching it) and can be used to configure the virtual PS2 (the emulated machine). And can be loaded from hardcoded data (inside the .self) or from an external file (this feature is supported only by ps2_netemu.self). Maximum CONFIG size for ps2_netemu is 16384 bytes.

The config data consists in a list of concatenated values of 8 bytes length (uint32_t), and can be processed like this:

<!-- We need to find a better way to organize the commands info below, right now all the info is "constricted" inside the same table but is better to take them out of the table to have more freedon when adding comments, etc... Are a lot so by now i prefer to dont make page sections for every command. Im going to try something that visually looks like page sections but are not (so are not going to be displayed in the TOC at top of the page). With this change we are moving forward because the command info is not going to be inside the same table anymore, im going to split them but the visual look and other details are not going to be definitive because later can be converted into page sections if someone insists in it -->
 
 
{{Boxcomm|id=0x00|name=Title ID Enforce / Multidisc config|data=1x String in format: ABCD-12345}}
Restricts the CONFIG to be used only by a specific [[Template:TITLE_ID_for_Physical_Media|Title ID]]
The presence of this command in the CONFIG is optional. If present it needs to be located always at the last position in the CONFIG. When bytes are present after Title ID, emulator read them to setup multidisc info.
Multidisc info bytes:
First byte:  Unknown, seems to be unused. 00 in known configs (Grandia 3).
Second byte: Discs count (0-9), when 0 or 1 emulator don't enable multidisc mode.
Third byte:  Which disc in set is this one (0-8 for discs 1-9)
Fourth byte: That one is optional, but very important. When set to 1,
              disc swap menu will be in "Reset game" menu and disc change will trigger reset (default behavior).
              But when this byte is set to 0, new option in main emu menu called "Switch Discs" will appear. Emulator change disc without reset.
              Keep in mind we don't know how accurate swap emulation is here, games are picky for some details.
              Every iso bin enc in set need to have proper data in separate config.

|0x0A|| Fix for TriAce executable unpack function.
Games unpack data using VU0 microruntime (not COP2). Because unpack involve floating points operations result can be inaccurate. And it is,
exactly by 1 byte. Config add 1 to result of unpacked data. This can be confirmed also on pcsx2 with turned off TriAce hack, example for Radiata Stories US release.
Set breakpoint on 0x124D90, and then when it's hit, add 1 to lower 64 bits of vf03 reg (in vu0f tab) and hit run.
Game now work as it should. On PS3 this probably can be fixed also by 0x11 command, but since they had hook already done before 0x11 was a thing, it stayed as is.

Config run the same function which is run when PS2 syscall 7 (ExecPS2) hook is triggered (0x1831A8 in latest emu memory).
Only difference is that 0x42 overlay is not reloaded, and check for "cdrom0" string is not performed.
Command could be potentially useful for games that like to change own code. Eg. Load "bin" files with code (HSG/HST), or modify own code by direct writes to memory (NFS Carbon CE...)

Check if a0 == 0x8000 (32768), apply config if true. Config is little bit more complicated than it should, emu flush all fpu regs to memory just to modify one field in altivec vector register.
When condition is met ps2 cop1 f08 register is modified from 0x40490FDB to 0x40490FDA, this result in next operations to end up as negative 0.0 (0x80000000) instead of just 0.0 (0x00000000).
Seems to trigger when loading of stage or loading of attract mode is close to finish or done.

|0x18|| Okami PAL specific hook.
Check if opcode at 0x183F04 of EE memory is jal 0x183CB0 (0x0C060F2C). This is used to run additional hook patcher only 1 time.
Later it will be nop here. so it means that new hooks are already applied. So function will just return early.
if opcode at 0x183F04 is still jal 0x183CB0 (0x0C060F2C),
then patch addresses 0x183F04 (jal 0x183CB0), 0x183F34 (jal 0x183CB0), 0x183F3C (jal 0x183D18) to nop.
Finally adds 3 additional EE hooks. Emu addresses for ps2_netemu 4.70+
EE address | EMU address
0x183F0C  | sub_46334
0x183F3C  | sub_45DA4
0x183D74  | sub_47B50
First hook is responsible for grabbing EE addresses from one of EE gpr register. Second hook perform few checks from data in EE gpr registers, and
eventually store data from EE gpr registers on previously grabbed addresses. Hook 3 store one of previosly grabbed EE address on unknown part of memory.
Whole thing looks like HLE version of noped functions.

Copy lower 64 bits of $v0 r5900 register to lower 64 bits of $a1 r5900 register.
All that to make next opcode (hook address + 4) "beq $a1, $v0, addr" always true. Because $a1 and $v0 now have the same value.
This in turn skip CTimer::GetTimeSeconds((void)) in function CReplay::NextFrame((CDrivingControls *)). Worth to note that CReplay::NextFrame seems to be not related to replay per se, but to car physics.

Command present only in the ps2_netemu. Maximum List Count: 32. Mode is first 4 bits of address field (Xyyyyyyy), can be either 0, 1, or 2. All known examples use this command in 0 mode, and modes 1 and 2 are here just for documentation purposes.

*mode 2 - NOP memory at selected range. Params: start address, end address, unused (can be anything, but is required to align config).
00000010  00 FF 0F 00 00 00 00 00  07 00 40 14 04 FF 0F 00 ..........@.....
Problem: Original opcode validity check is performed before testing config for special cases. Thus making mode 2 almost inaccessible.<br>
00000020  00 00 00 00 10 00 01 3C  08 FF 0F 00 00 00 00 00 .......<........
Solution: We can patch that one line of code by the same 0x0A config. So if we want to nop region from 0x100000 to 0x100080, first we need to patch 0x100000 to 0x100080 opcode. So check will pass, "simple" as that.

Offset on the disc = sector id * sector size + offset + correction [see below]<br>
Offset correction is based on selected read mode (not on media type):<br><br>
CDRead requested block size (CD disc):
*2048 = Offset + 0x18 (skip 12 sync bytes, 4 of header, and 8 of subheader)
*2328 = Offset + 0x18 (skip 12 sync bytes, 4 of header, and 8 of subheader)
*2340 = Offset + 0x0C (skip only 12 bytes of sync data)


|-
DVDRead requested block size (DVD Disc):
| NPUD21604 || GRIMgRiMoiRe ||
*2064 = Offset match, but only until the 349th sector. Otherwise is offset - 0x0C because that read mode see data as ID DATA (4) + ID DATA EDC (2) + Reserved bytes (6) + 2048 data + EDC (4).

"Offset + XX" for CD assume that you use Isobuster RAW mode. "Offset - XX" for DVD assume that you use Isobuster NON RAW mode<br>
0x3D => 0x3D12 (15634)
Special case is DVD read on very low sector, here you need to use exact offset without substrating 0x0C. Highest confirmed sector that don't use correction for now is 349.

VU0/COP2 related multicommand.
|-
First 8 bytes of that command are special flags. Not quite sure about bytes 5-8 yet,
! ID !! Title !! Config Data !! Revision !! Notes
because at some point they are used to "andc" with first 4 bytes.
|-
Some examples for first 4 bytes:
| ALL || .hack\\infection Part 1 ||
0x1000    = Run additional flag related code after every FMAC operation, VU0 only, COP2 do this by default.
  00000000 3D 00 00 00 89 3D 00 00 08 00 00 00 FF FF FF FF =....=..........
  0x2000    = Emit some additional code when lower opcode is fsset, this flag require 0x1000 to be enabled. VU0 only.  
  00000010 FF FF FF FF 8D 94 11 01 FC 0E 00 80 FF FF FF FF ................
0x100000  = When enabled opcodes like MSUB, MADDA, etc, do proper multiply first, then add/sub. When disabled (default) single opcode is used (vmaddfp / vmmsubfp). Not used in COP2 mode.
  00000020 FF FF FF FF 8D 94 11 01 03 02 03 10 08 00 00 00 ................
              Note: When this command is disabled, then "Accurate MUL" is skipped for MADDxx/MSUBxx regardless that 0x30000000 is set or not.
  00000030 FF FF FF FF FF FF FF FF 40 A7 E0 01 3C 03 00 80 ........@...<...
              Because there is no way to do correct MUL separately when altivec madd/msub is used.
  00000040 FF FF FF FF FF FF FF FF 40 A7 E1 01 FC 1E 00 80 ........@.......
0x200000  = Run some additional code in VU0 load/store opcodes (ILW, LQI, ISWR, etc.) Not used in COP2 mode.
  00000050 00 00 00 00        ....
0x400000  = Skip emu syscall 3 (3)
|| 15753 (3.73+) || fix freeze
0x800000  = Skip emu syscall 3 (4)
0x4000000  = Enable type 2 config from cmd 0x12.
0x8000000  = Accurate VU0 DIV opcode, not used in COP2 mode.
  0x10000000 = Fast Accurate VU0 MUL. Try to round mantissa. Opcodes like MSUB/MADD additionally require 0x100000 to be enabled, otherwise command skip them. Not used in COP2 mode.
  0x20000000 = Full Accurate VU0 MUL. Use runtime from CMD 0x10, but for every matching VU0 opcode, including opcodes like MSUB for mul part.
              Opcodes like MSUB/MADD additionally require 0x100000 to be enabled, otherwise command skip them.
   
  Selecting both 0x10000000 and 0x20000000 (0x30000000) work the same way as 0x20000000.
  Keep in mind that you still need to use at least 8 bytes for cmd 0x12, just use 00 for bytes 5,6,7,8.  
Later bits are dependent on which subcommand we want to run.

Patch SPE 0 (IOP) program in local memory. Command search for absolute branches in LS 0x3A2C0 - 0x3A6C0 and patch first branch that match to "bi r127". That weird approach was probably used because spe program differ little bit between emu versions, so they don't need to update command on every new emu revision. Currently (4.75+) this command patch branch at address 0x3A3A4 (bra sub_2E600). This command takes partially unused value. Value 0,1 do nothing, values 2 and above run command. Doesn't matter is 2,4, or 10. Nothing will change in command behavior.

Copy VIF1 command 01h STCYCL handler struct into unused 08h slot (slots are 100 bytes per command, include pointer to function that handle command, and other data). Then patch slot 08h function pointers to function at 0x14E00. 08h is normally unused, and handled as a NOP. This command is useful only with additional 0x01 (0x13-0x15) hooks, which inject 08h VIF1 command into game code when other conditions are met.

Applied on game start (more precisely while executing ps2 bios syscall 7 ExecPS2), if game overwrite selected part of memory, it will wipe 0x42 patch. See [[Special:Diff/67828/67858]]

Start address can be (in theory) anywhere, but Sony used the 0xFF000 - 0xFFFFC range for this purpose.
  00000010  50 2E 41 00 00 00 00 00                          P.A.....
Count is size of patch in 4 bytes opcodes. So 5 opcode patch = count 5.
|| 15753 (3.73+) || fixes freeze when something in 3D appearing
Opcodes will be placed on selected address, we use only patch code, no need for original opcode.
  0x3D => 0x3D89 (15753)
  Next opcode addresses are auto calculated (+4..) so we need to specify only patch start address.
0x27 => 0x412AD8, 0x412E50
Remember we need to jump to our new code, best way is command 0x0A with j (jump) opcode.
Also is important to add return jump if required. That one need to be added in our 0x42 patch.
  Maximum opcodes count seems to be 0x3FF (1023 opcodes).

Allow  display_mode 1 (CELL_GCM_DISPLAY_480_unk2) (59Hz?) [640x480]
and    display_mode 5 (CELL_GCM_DISPLAY_720P_59)          [1280x720]

Both 480 modes can be either I or P, so is something else, probably 59/60Hz.
This config possibly affect only in-emu UI, but this require testing.

===Config data examples (hardcoded)===
{{Boxcomm|id=0x46|name=Enable L2H Improvement|data=N/A}}
====Inside ps2_emu.self====
Performance related setting for titles using L2H (Local to Host, so called GS download (from GS to  EE))
Embedded patches are based on Checksum/Hash of title. ps2_emu is only emulator version where patches are described inside self file in ascii. Known patch types described in ascii are: Patch data, new SPU2 params, and Setting mecha HACK to show GODZCD as GODZCDDA.
SMT Digital Devil Saga 1 - Crazy amount of GS downloads used to draw characters in-game
SMT Nocturne
Fatal Frame II
Other games affected (not in official config)
Soul Calibur 2 - When looking at the sun
GT4 - When looking at the sun
Valkyrie Profile 2 - Similar situation to SMT DDS1, in Solde game literally do thousands of 30QWC downloads all the time.
Tak and the Power of JuJu - Fix freeze during loading of the Burial Ground level in the NTSC version. This probably getting lucky with VIF1/GIF timing, normally command is not supposed to fix hang issues.
 
{{Boxcomm|id=0x47|name=Enables XOR CSR|data=N/A}}
Graphics related setting.<br>
XOR  bit 13 of GS CSR register (CSR.FIELD). Should fix fullscreen line corruption, maybe some interlacing issues. Long shot, but can possibly affect SCANMSK games.
 
{{Boxcomm|id=0x48|name=VSYNC Delay|data=2x uint32_t}}
*First param possible value are 1 = No IPU, 2 = IPU, 3 = Anytime.
*Second param is delay (in ms?), and can be also negative value.
**Emu has standard presets for second param.
***Agressive = 0x3D090 (250000 decimal),
***Normal = 0x186A0 (100000 decimal),
***Conservative = 0x4E20 (20000 decimal),
***But other values can be used.
[SMT Digital Devil Saga 1] uses 1, 0x3D090
[Fatal Frame II] uses 0x2, 0xFFFFE69C (-6500 decimal)
 
{{Boxcomm|id=0x49|name=Unknown|data=N/A}}
Skip part of code which use GS XYOFFSET_1 register, possibly ignore it at all. 
Trapt
 
{{Boxcomm|id=0x4A|name=Unknown|data=N/A}}
Change VIF1 command 14h MSCAL behavior to use 15h MSCALF (VIF1) instead. MSCALF behavior is the same as MSCAL, but also waits for PATH1 and PATH2 to not be active before starting a microprogram. This is hack, and MSCAL should be fixed instead to wait in queue instead of triggering early.
Applies to the Snowblind Engine games. Fixes the rest of flickering textures.
Meant to be used in conjunction with the GX/SOFT Snowblind Engine's specific commands (double 0x01 and 0x23 combo).
 
{{Boxcomm|id=0x4B|name=Redirect SAVEDATA by ID|data=2x uint32_t + ID: offset, int, char[]}}
For proper config we need at least 2 (can be more if needed) 0x4B commands, one to enable redirect, one to disable.
First param is EE memory offset that when is hit enable/disable redirection.
Second param is used to select which card will be redirected:
  0x00 do nothing
  0x01 for SCEVMC0.VME
  0x02 for SCEVMC1.VME
  0x03 for SCEVMC0.VME and SCEVMC1.VME
  0xFFFFFFFF to disable redirection, and use original VMEs.
Third param is ID of SAVEDATA we want to use padded with 00 to match 12 bytes, or all 00 in disable redirect config.
Important note here is that config have own 00 00 00 00 terminator at the end.
So after 12 bytes of ID we need to add 4 bytes of 00. That apply also to disable redirect version.
Under the hood config also setup 0x01 hook commands with 0x39 subcommand on selected addresses.
 
{{Boxcomm|id=0x4C|name=Unknown|data=2x uint32_t + ID: offset, int, char[]}}
Used to redirect to different ISO without game reset. First param is EE offset to hook, second param is some kind of mode selector, depending on that
emulator later set mecha switch disc state:
  mode 0x01 = set disc switch state to 1 (on next mecha main loop it will emulate opening the tray).
  mode 0x02 = set disc switch state to 3.
  mode 0x03 = set disc switch state to 3. This state repeats because it work different way depending that emulated tray is closed or no.
  mode 0x04 = set disc switch state to 2.
  mode anything else = do nothing.
Third value is ID in big endian hex ascii (eg. NPJD12345), additionally 0x4C expect own 00 00 00 00 terminator. To eventually end redirection use
another 0x4C but with (offset, 0xFFFFFFFF, 4 * 0x00000000 . This config have very similar usage to 0x4B, just redirect to different iso, instead to
different MC. Currently is unknown that cobra patched emulators support that config properly, and swap disc thru 0x00 command seems to be easier.
This config don't work if 0x00 multidisc config is detected. Config under the hood setup 0x01 hooks with subcommand 0x3A
 
{{Boxcomm|id=0x4D|name=Unknown|data=1x uint32_t}}
Param is floating point value. Default value 0.
if Q in GS RGBAQ write is 0.0 or -0.0 then
    Q = Q | value from config
else
    Q = Q
 
Wild Arms: The Fifth Vanguard uses 0x3F800000 (1.0)
 
{{Boxcomm|id=0x4E|name=Unknown|data=Unknown}}
 
{{Boxcomm|id=0x4F|name=Unknown|data=Unknown}}

==TitleID/DiscID in ps2_netemu.self==
==Known Emulation Bugs==
There are 193 titleIDs listed inside ps2_netemu.self. More precisely, into XPARAM2.ELF file of PS2 Bios included in ps2_netemu.self. Usage of those IDs is currently unknown.
This list known bugs inside emulator code that make emulation inaccurate. Since those are only EE side bugs for now, ps2_gxemu/ps2_netemu/ps_softemu share the same issues.  
There are internal flags related to every title ID included inside file, still unknown what they do. Also some arguments, in plain text. File in real ps2 is introduced in SCPH-750XX models so exactly when DECKARD Power PC chip exchanged original IOP chip. This can explain why it is still in PS3 netemu bios. Because PS3 it is ppc that can need the same/similar flags.
 
Original PS2 bios include similar list file called XPARAM.ELF, but Title IDs there are not the same, although some of them exist on both lists.

|-
! ID in ps2_netemu.self !! Title !! Remarks
| Missing Emotion Engine Data Cache emulation || Emulating that is literally not possible without making games run at 3 fps. Fixed by patches to game image, or EE code. Instruction Cache (not Data) seems to be implemented, at least partially. || Ice Age 2, DOA2: Extreme, Nascar 2009.
|-
|-
| Branch delay slot violation not supported on EE || Some games have Branch instruction inside Branch delay slots, this is not emulated correctly on EE (VU have proper emulation of that). This is patched in configs by rearangging MIPS code. || WRC 3,4,Rally Evolved, one of Action Replay discs. 
|-
|-
| SLUS_214.52 || Valkyrie Profile 2: Silmeria ||  
| Unmapped write only EE memory (confirmed only for SIF) || Reads/Writes to 0x2000000+ shouldn't throw bus error on dma transfers. Write should be performed as successful, memory should stay unchanged. Reads should return 0. || Games developed by In Utero, while creating initial save file, send DMA where address is EE stack pointer. At the time of transfer start $sp is too high, and requested transfer size make MADR overflow above 0x2000000 at some point. This is game bug, and happen also on real hardware. Fixed by config.
|-
|-
| SLUS_214.04 || Final Fantasy XI: Treasures of Aht Urhgan ||  
| VIF bugs || There is no correct timing, and queuing for some VIF commands like MSCAL. || Snowblind Engine games. Probably more.
|-
|-
| SLUS_213.39 || Puzzle Challenge ||  
| XGKick is instant || Some games expect to XGKick happen few cycles in future, on PS3 is done instant. Fixed by config 0x07 which delay XGKick by selected value || WRC series, Wakeboarding Unleashed, TriAce games, World of Outlaws - Sprint Cars, Ty - The Tazmanian Tiger, dot Hack - G.U. series, and more
|-
|-
| SLUS_213.31 || Sonic Riders ||  
| COP2 instructions are instant || Some games rely on fact that COP2 operations can take some time, on PS3 emulators they are done instantly due to lack of correctly emulated pipeline Patched by rearranging mips code || FFX, FFX-2, Ghost in The Shell SAC, Ace Combat series, Sprint Cars 1/2, Black, Run Like Hell, Everblue 2, Dragon Quest - Shounen Yangus no Fushigi na Daibouken, and many more
|-

| SLUS_210.89 || Karaoke Revolution Vol.3 ||  
| VU0 is not running in sync with EE core || VU0 is running program "at once", which mean that VU0 run until it hits E bit. From EE perspective it looks like whole VU0 program run in 1 cycle. Games that expect VU0 registers to be changed from EE side while VU0 is running are broken due to that. Partially resolved using 0x12 command with 2/3 subcommands, or by code rearranging.|| 24 The Game, ATV Quad Power Racing 2, Twisted Metal Head-On, Primal, Ghosthunter, Rayman Arena, Rayman 3, Largo winch. All games using M-bit.
|-
|-
| SLUS_210.70 || Final Fantasy XI: Chains of Promathia ||
| M-Bit not supported || Emulator ignore VU0 M-Bit, that cause issues for games that need it to work correctly. This is done because there is no way to sync correctly running VU0 without sync with EE. Partially resolved on emu using 0x12 command with 2/3 subcommands, or direct VU0/MIPS code rearranging. || Totally Spies! Totally Party, Mike Tyson Heavyweight Boxing, My Street, Crash Twinsanity, Marvel Nemesis, Panzer Elite Action - Fields of Glory, TriAce games (speed optimizations only), Super Monkey Ball Adventure, most Eko Software games, and many more.
|-
|-
| SLUS_210.59 || Tekken 5 ||  
| T-Bit not supported on VU0 || Emulator ignore VU0 T-Bit, that cause issues for games that need it to work. Note: T-Bit is correctly handled for VU1. || Spiderman 3 set T-Bit, then do cfc2 from TPC (address where VU0 stopped). Since T-Bit is ignored, TPC is wrong. Value is later copied to CMSAR0, and program continue at wrong address. Well that's what should happen, but T-Bit also not signalize correct bit in VPU-STAT. Causing another issue, also in Spiderman 3.
|-
|-
| SLUS_209.18 || Super Monkey Ball: Deluxe ||  
| Emulator do not update correct flag instances for COP2 while ending VU0 program on Ebit || This cause few games to read bad flag status (not status flag!) on COP2. This is resolved on emu by forcing update of MAC flag on every STATUS flag read (by config 0x12), this cause slowdowns creating a lot of unnecessary operations. || Driving Emotion Type-S, State of Emergency 2, The Getaway Black Monday.
|-
|-
| SLUS_208.91 || Star Ocean: Til the end of Time [Disc 2] ||  
| Not updated status flag when VDIV/VSQRT/VRSQRT is done on COP2 || Potential bad flag state can cause a lot of issues that are not related on first sight || Yanya Caballista (already patched by custom config)
|-
|-
| SLUS_208.51 || Ace Combat 5: The Unsung War ||  
| In corner cases emu select wrong block flags pipeline state (both VU0/EEonBE and VU1/VRC affected). || This can cause various issues, mostly SPS, missing graphic, specific slowdowns, etc. Issue seems to occur when branch/jump delay slot have opcode important for flags calculation. Theory is that cached microprogram don't include modified flags state from delay slot instruction. So when already recompiled program is fetched from pool, it will miss one cycle in fmac flags pipeline. This can be crucial in games that rely on it. || Tales of Legendia and Klonoa 2 set sticky flag bits to 0 and branch with sub.xyzw in delay slot (expecting that sub change status flag), Tamsoft engine games set sticky bits to 0 in branch delay slot, this was most ridiculous bug, because problematic branch was pointing to next opcode after delay slot, removing branch was enough. True Crime: NY is only known game where VU0 is affected by this bug. more..

|-
| SLUS_208.38 || All-Star Baseball 2005 ||  
| CTC2 opcode write whole value to R register, while only 23 bits are writable. Rest is hardcoded to 0x3F800000. || Can cause many weird issues like broken physics, broken graphics. PCSX2 was also affected [[https://github.com/PCSX2/pcsx2/pull/6611 more]]. || The one game that is known to be affected, and is already patched, is Musashi: Samurai Legend.
|-
|-
| SLUS_206.86 || Splashdown: Rides Gone Wild ||  
| CFC2 from R register should return only 23 lower bits. || CFC2 from R on real PS2 return only lower 23 bits. Originally found out by PCSX2 team  [[https://github.com/PCSX2/pcsx2/pull/8409 more]] and later confirmed to affect ps2_netemu in emu assembly. || There is only one game that is known to be affected, Onimusha Dawn of Dreams.
|-
|-
| SLUS_206.39 || Def Jam Vendetta ||  
| Missing floating point result overflow/underflow detection (U/O flags not set) || Since this affect all units (FPU/VU), many issues can occur. But in reality it seems to not affect any games. While this is easier to implement than on x86 system (full floats range, compared to ieee754), there is no way to do that by hardware way. Because SPU add/sub don't set those flags on single precision operations, and vmx have them disabled in spu compatibility mode. || Superman Returns.
|-
|-
| SLUS_206.35 || Muppets Party Cruise ||  
| DMA between SPR and VU1 memory cause emulator panic. || Currently cause is unknown. It seems that functions responsible for transfer don't check that VU is running. Manual state that dma can be performed only when VU is not active, and pcsx2 wait until VU end. Games affected in emulators on ps3 display this warning in pcsx2 if mtvu is enabled: "MTVU: SPR Accessing VU1 Memory". Affected games are fixed by rearranging code to do lq/sq loop instead of DMA. || Summoner 2 (SPRfrom to VU1 data mem), Kaena (SPRto from VU1 data mem).
|-
|-
| SLUS_205.90 || Spyhunter 2 ||  
| IOP SIF0/1 DMA IRQs can be disabled (masked), which is not true on real hardware. || IOP interrupts 0x2A and 0x2B should always trigger. Fixed by patches to IOP code. Ps2_emu seems to be unfacted, probably handled on real hw in CXD9208GP. || Knockout Kings 2001, DOA2: Hardcore.

| No mipmapping support || Emulator does ignore the mipmap layers, probably for performance reasons. It is processing only the level 0 texture base pointer specified in the TEX0 register. There are games writing garbage data into that memory area, when the mipmap level is different than zero. As a result, a garbled texture is shown instead of a correct one. || Ace Combat series, Ape Escape 2, EA Sports F1 series, Harry Potter series, ICO (psuedo volumetric rays), Jak and Daxter series, Nickelodeon Barnyard and Nicktoons Unite (very strange implementation), Ratchet and Clank series and more.

There are other unofficial ways to patch the PS2 games such the [https://forums.pcsx2.net/Thread-A-simplistic-guide-to-pnach-files-aka-pnach-for-dummies pnach] format, or the widescreen patches that allows 16:9 screen output for some games by hex editing the ISO, or by applying ppf patches. Games work fine on PS3 with same compatibility like before patching. Also some 480p (aka progressive scan) patches work fine. http://ps2wide.net/
 
The problem of this methods is the patch is applyed over the ISO and is modifyed permanently, but this problem can be avoided in PS3 because that unofficial patches can be "ported" to the official config format to be used by ps2_netemu.self, by using the official config format the settings and patchs from the config file are applyed "on the fly" and the ISO is not modifyed
 
==ps2_title_brute code==
 
A script to calculate cdvd key magic used in ps2emu, gxemu and softemu from given input title id.
On real PS2 this value seems to be stored at 0x1F402020-0x1F402024.
It contains code for bruting as well. Just call gen_sum with the title id in a specific format to get it.

Description

Simplified block diagram of a PS2
source

Emulation of Playstation 2 is currently handled by 3 kind of emulators. CECH-A/B models use ps2_emu.self able to use built-in PS2 hardware (EE/GS/Rambus memory), and have best compatibility. CECH-C/E use ps2_gxemu, this emulator use physical Graphic Synthesizer found in this ps3 model, but Emotion Engine is fully emulated here, also there is no Rambus memory. All other models emulate PS2 thru fully software based ps2_netemu used for ps2 classics, and hacked now to use decrypted ISO files. Earlier before Sony provided ps2 classics on PS Store there was another soft only emulator strongly based on ps2_gxemu. It was called ps2_softemu, and had support for original PS2 CDVD. Only emulator not able to run physical discs is ps2_netemu.

Emulators are self files, but not typical one. Emulators are not truly PS3 Game OS elf executables, but Guest OS'es running on LV1 of PS3. This mean that LV2, or more friendly Game OS is unloaded before emulator is loaded. This also mean that while emulators are running we can't call any LV2 function. Also LV1 syscalls are limited to call from all emulators, but can be fully unlocked.

All emulators use built-in stripped developement version of PS2 BIOS with disabled debug functions that can affect some games. This is done because some games print debug info on screen when found that are run on dev bios. Bios between ps2_emu, and ps2_gxemu/ps2_netemu are different. Ps2_emu BIOS is able to run only on ps2emu version of emulator due to RDRAM check.

PS3 models without Emotion Engine unit use "SPE-compatible SIMD graphics-rounding mode for VMX/Altivec Instructions" for FPU, and VU0 emulated floats calculations. This is set on emulator init by HV call 97 with param 1. VU1 actually run at SPE core so no compatibility mode need (or can) to be set. SPE compatible mode for PPE mean that rounding mode is set as round to zero, denormals are treated as zero, and there are no infinities or NaNs. So theoretically what PS2 FPU/VU was originally. Although SPE and PPE SPE compatibility mode is still inaccurate comparing to PS2, because Sony decided to cut off 2 guard bits from calculations on PS2. Probably because there was no need for round and sticky bits (no Nan/Inf, one round mode, etc.). Additionally float divide algorithm is custom and not fully understood up to this day. Good example here are TriAce games, or Castlevania COD where SPE calculation is wrong by 1 bit making games unplayable without patch. This are PS2 math algo specific inaccuracies in FPU/VU implementation that are not present on any other hardware.

General observations regarding PS2 Classics emulator (ps2_netemu)

  • Virtual memory cards are per title based, but apparently run through the current memory card system. The module used to manage memory cards is: vmc_savedata_plugin.sprx - Using a regular memory card that has been renamed result in a "The save data is corrupt (8XXXXXXX) error"
  • Loads an epilepsy warning before PS2 logo (PS button menu appears during epilepsy warning if controller is synced)
  • Does not support online functionality of PS2 titles (network configuration utility inside Full Spectrum Warrior claims no network adaptor has been found, same with Syphon Filter: The Omega Strain).

- Only file that is needed in the folder for PS2 Classics is "iso.bin.enc". Removing the manuals/DXT files will cause the game to boot IMMEDIATELY to the PS2 logo upon switching to 720p/starting PS2 LPAR.

LIMG Segment

The ISO.BIN.ENC has a block of 0x4000 bytes added at the end codenamed "LIMG" that works as a descriptor for the ISO structure

SPE local storage

Emulator access SPE LS by accessing special addresses. Mapping as follows:

SPE Num. SPE task Address in netemu address in SPE
0 IOP 0x40000000 - 0x4003FFFF 0x0 - 3FFFF
1 SPU2 0x40080000 - 0x400BFFFF 0x0 - 3FFFF
2 VU1 0x40100000 - 0x4013FFFF 0x0 - 3FFFF
3 EEDMA 0x40180000 - 0x401BFFFF 0x0 - 3FFFF
4 FE 0x40200000 - 0x4023FFFF 0x0 - 3FFFF
5 BE 0x40280000 - 0x402BFFFF 0x0 - 3FFFF
6 IPU 0x40300000 - 0x4033FFFF 0x0 - 3FFFF

Additionally, emulator access SPU directly with those addresses.

Address Channel Channel description Access type Notes
0x44004 SPU_Out_Mbox SPU Outbound Mailbox Register Read only Used to read 32 bits of data from the corresponding SPU outbound mailbox queue. Outbound Mailbox Register has a corresponding SPU Write Outbound Mailbox Channel for writing data into outbound mailbox queue.
0x4400C SPU_In_Mbox SPU Inbound Mailbox Register Write only Used to write 32 bits of data into the corresponding SPU inbound mailbox queue. Inbound mailbox queue has a corresponding SPU Read Inbound Mailbox Channel for reading data from the queue.
0x44014 SPU_Mbox_Stat SPU Mailbox Status Register Read only Contains the current In_Mbox/Out_Mbox/Out_Intr_Mbox count of the mailbox queues in the corresponding SPE.
0x4401C SPU_RunCntl SPU Run Control Register Read/Write Used to start and stop the execution of instructions in the SPU.

The SPU can dynamically change the state of the Run Status bit (that is, SPU_Status[R]).

0x44024 SPU_Status SPU Status Register Read only Used to report the status (state) of an SPU. Emulator use it mostly to check if SPU is running (bit31).
0x44034 SPU_NPC SPU Next Program Counter Register Read/Write Contains the address from which an SPU starts executing when the Run Control bit is set in the SPU Run Control Register.

Used in function that start SPU programs, and in interrupts handlers, plus in few other places.

0x5400C SPU_Sig_Notify_1 SPU Signal Notification 1 Register Read/Write Used to write data that can be read in SPU_RdSigNotify1 channel corresponding SPE.
0x5C00C SPU_Sig_Notify_2 SPU Signal Notification 2 Register Read/Write Used to write data that can be read in SPU_RdSigNotify2 channel corresponding SPE.

Address = SPU base + Address. For example, IPU SPU is mapped to 0x40300000 so accessing SPU_Sig_Notify1 will be done by read/write to 0x4035400C.

ps2_netemu.self

Support for USB devices seems to be limited comparing to other available emulators. Although PS2 side of USB subsystem seems to be fully implemented. IOP emulator in SPU handle USB HW registers addresses and generate interrupt for PPU which later handle RW to mentioned registers in similar fashion to ps2_emu/ps2_gxemu. PS2 side of things can be disabled/enabled using one byte, when disabled USB writes are ignored, and USB reads return 0. Initial state is unknown. Emulator seems to accept HID controllers and use them as DS3.

Supported devices:

  1. BD Remote Control
  2. PLAYSTATION(R)3 Controller (Vendor ID 0x54C, Product ID 0x268),
  3. Motion Controller - Move (Vendor ID 0x54C, Product ID 0x3D5),
  4. Navigation Controller (Vendor ID 0x54C, Product ID 0x42F)
  5. "guncon3"


Unknown:

  1. Vendor ID 0xF0D (Hori), Product ID 0x4A
  2. Vendor ID 0x54C (Sony), Product ID 0x5AF


Few peripherals not listed above work fine or with issues.

  1. PS3 Dance Dance Revolution Dance Pad - not ps2 accessory, opposite arrows can't be pressed at the same time.
  2. Pop'N Music controllers - Require PS2 to USB converter. Wrong button mappings can be fixed by remap in config file.
  3. Retro-Bit Official SEGA Mega Drive USB 6-Button Controller. Mapped for PS3 already and also works with this emulator. Lacks analogue sticks and shoulder buttons.

Ps2_netemu use integrated PS2 bios included in ps2netemu.elf, not additional file like in ps1_emu. In 4.81 firmware BIOS is located from 0x820A00 to 0x9F09FF (0x820900 to 0x9F08FF in fw4.50). Bios version is Developement v2.20 (22/01/2007).

Notable thing is that ps2_netemu use the same bios as ps2_gxemu, and ps2onps4. ps2_netemu not boot using ps2_emu bios because of failing RDRAM check.

Bios region patch

Emulator patch loaded bios image to set proper region based on target_id, and string (separated for readability): 

JJjpnJJ  AAengAUU EEengEEE EEengEOA HHengJAG ERengERD CCschJCC HKkorJAG HHtchJAG AAspaAMM

Note: Additional space after first set is intentional and exist also in full string.

Target id to region pairing: 

* JJjpnJJ  for 0x83
* AAengAUU for 0x84 , others (DECR, etc.)
* EEengEEE for 0x85 , 0x87 (also forced if game id from SYSTEM.CNF is xxEx_yy.zzz)
* HHengJAG for 0x86 , 0x8A , 0x8E
* AAspaAMM for 0x88 , 0x8F
* EEengEOA for 0x89
* HHtchJAG for 0x8B
* ERengERD for 0x8C
* CCschJCC for 0x8D (unreleased PS3 Chinese model)
* HKkorJAG unused

Bios is patched using EE memory mapping addresses, so offset in file + 0x1FC00000. Using HKkorJAG example, addresses below are set to: 

* 0x1FC7FF04 = H (x in "0220xD20121227" string)
* 0x1FC7FF14 = K
* 0x1FC7FF15 = k
* 0x1FC7FF16 = o
* 0x1FC7FF17 = r
* 0x1FC7FF52 = J (x in "System ROM Version 5.0 12/27/12 x" string)
* 0x1FC7FF20 = A
* 0x1FC7FF90 = G

Virtual PS2 HDD

There are 2 different "PS2 game" contents that can be installed in PS3 HDD (CATEGORY's 2P and 2G ). 2P are games released from PSN as "PS2 Classic" in .PKG format, and 2G are a few real "PS2 DVD discs" that can be installed in the PS3 HDD, this installation is managed by the PS2_system_data.pkg.

This games can be installed in real PS2 (in the internall HDD of a PS2 fat)... later this same installation was used in the PSX... and when implemented in PS3 there was needed to use a virtual PS2 HDD image file keeping the same format than the original HDD used in PS2.

Game files (extracted from the real PS2 disc) are installed in a IMAGE.DAT file, this file is a 1:1 "raw copy" of a PS2 HDD.

This IMAGE.DAT is placed in the "install folder" (inside USRDIR folder) and his size can vary up to 10+GB

There are 2 different installations: the most common is used to store "game expansions" (e.g: used by additional content in SOCOM games)... the other type of installation is a "full install" and it seems the only game that uses it is "Final Fantasy XI" (main game installation when the game boots for first time + game expansions added later when needed in the same IMAGE.DAT)

PS2_system_data.pkg itself uses an IMAGE.DAT file (6.43 MB)

The structure of this "virtual PS2 HDD" uses an "APA header" and a "APA MBR" + several "APA partitions", some of them containing "PFS filesystems". 

Error message trying to boot a CATEGORY "2G" game with hand-made SFO's and invalid IMAGE.DAT file:
The game partition for this game cannot be created because the installed game is corrupted.
To perform this operation, delete the game, and then reinstall the game using the disc.

Game CONFIG

Some of the PS2 emulator types (such ps2_gxemu.self, ps2netemu.self) are able to load config commands that are applyed "by game ID". The concept of "game patches" is not technically correct because some of the commands does patching functions but others does other things (not patching), and other commands works as switches or sets a value that are enviromental settings for the emulator (not for the game) but because are applyed "by game" should be considered enviromental settings for that specific game, so for simplification purposes you can think in all this data as "game configs"

This "game config" data seems to work in the same way for all the PS2 emulator types but can be located in different places, some are hardcoded inside the emulators itself (inside the .self), and at the time the "PS2 classics" emulator (ps2_netemu.self) was developed this config can be loaded from an external file

In short, the "game configs" can modify the game image (by patching it) and can be used to configure the virtual PS2 (the emulated machine). And can be loaded from hardcoded data (inside the .self) or from an external file (this feature is supported only by ps2_netemu.self). Maximum CONFIG size for ps2_netemu is 16384 bytes.

The config data consists in a list of concatenated values of 8 bytes length (uint32_t), and can be processed like this: 

union{
 uint32_t command
 ...data...
}

Config Commands

ps2_netemu.self fw4.50 sub_12D7D8, fw4.81 sub_12E050
params are uint32_t unless noted.

At the time of writing this, most of the commands are completely or partially unknown.

0x00 Command Name: Title ID Enforce / Multidisc config
Command Data: 1x String in format: ABCD-12345

Restricts the CONFIG to be used only by a specific Title ID The presence of this command in the CONFIG is optional. If present it needs to be located always at the last position in the CONFIG. When bytes are present after Title ID, emulator read them to setup multidisc info. 

Multidisc info bytes:
First byte:  Unknown, seems to be unused. 00 in known configs (Grandia 3).
Second byte: Discs count (0-9), when 0 or 1 emulator don't enable multidisc mode.
Third byte:  Which disc in set is this one (0-8 for discs 1-9)
Fourth byte: That one is optional, but very important. When set to 1,
             disc swap menu will be in "Reset game" menu and disc change will trigger reset (default behavior).
             But when this byte is set to 0, new option in main emu menu called "Switch Discs" will appear. Emulator change disc without reset. 
             Keep in mind we don't know how accurate swap emulation is here, games are picky for some details. 
             Every iso bin enc in set need to have proper data in separate config.

0x01 Command Name: EE_ADD_HOOK
Command Data: 2x uint32_t Params (addr, func_id 0-0x3B)

Most of the hooks availables in netemu command 0x01 are fixes for a specific game, or a game engine
The Maximum Amount of times netemu command 0x01 can be used consecutivelly in the same config is 255. This is actually limit for EE hooks at all, 0x01 don't have own limit.

Function ID Notes
0x00 FIFA 2000 use it as hook for EE kernel at 0x800017E8 (DMAC related). Command backup value from r5900 s0 register.
0x01 FIFA 2000 use it as hook for EE kernel at 0x80001858 (DMAC related). Command restore previously backed up value to r5900 s0 register.
0x02

Max Payne 

Write 0 to D_ENABLEW in SPE 3 (EEDMA). D_ENABLER is NOT updated on PPE side.
0x03

Max Payne 

Write 0xFFFFFFFF (0x10000, other bits are ignored anyway) to D_ENABLEW in SPE 3 (EEDMA). D_ENABLER is NOT updated on PPE side.
0x04 Castle Shikigami II 
Skip r5900 CACHE IXIN/IHIN (Index/Hit invalidate) opcodes. Same as 0x03 command, but applied of selected ee offset.
This is probably command from times when 0x03 was non existing, and while it apply on selected ee offset, command never recover default IXIN/IHIN handling.
Note: There is leftover in emulator from command that reenable default behavior, but is unused now, and is not accessible by current config commands.
0x05 Force events test if D2_CHCR & 0x100 is true (if GIF dma is running). For more info check _cpuEventTest_Shared from pcsx2. Star Wars games developed by Pandemic Studios (freeze fix), Worms 3D and NBA 08.
0x06 Force events test if D1_CHCR & 0x100 is true (if VIF1 dma is running). For more info check _cpuEventTest_Shared from pcsx2.
0x07
0x08 Backup current unmodified COP0 status register state. Then disable EI bit, and notify emu that cmd 0x09 could be run. Harry Potter - Quidditch World Cup US use it at offset 0x2BD45C (EE)
0x09 Restore COP0 status register state from previously created backup. Harry Potter - Quidditch World Cup US use it at offset 0x2BD620 (EE)
0x0A Fix for TriAce executable unpack function. 
Games unpack data using VU0 microruntime (not COP2). Because unpack involve floating points operations result can be inaccurate. And it is,
exactly by 1 byte. Config add 1 to result of unpacked data. This can be confirmed also on pcsx2 with turned off TriAce hack, example for Radiata Stories US release.
Set breakpoint on 0x124D90, and then when it's hit, add 1 to lower 64 bits of vf03 reg (in vu0f tab) and hit run.
Game now work as it should. On PS3 this probably can be fixed also by 0x11 command, but since they had hook already done before 0x11 was a thing, it stayed as is.
0x0B Set lower 64 bits of mips $at register to 0
0x0C Piglet's Big Game
0x0D usleep(100)
0x0E Used 3 times in Need for Speed - Carbon [Collector's Edition] US. 
Used in place where game load code overlays, and in place where game self modify code. 
Config run the same function which is run when PS2 syscall 7 (ExecPS2) hook is triggered (0x1831A8 in latest emu memory).
Only difference is that 0x42 overlay is not reloaded, and check for "cdrom0" string is not performed. 
Command could be potentially useful for games that like to change own code. Eg. Load "bin" files with code (HSG/HST), or modify own code by direct writes to memory (NFS Carbon CE...)

store 0 in [ 0x204FC500 + 200000000 base] 0x4FC500 EE memory, and set lower 64 bits of mips $s0 register to 0.
0x13 Snowblind Engine specific fix. Applies to the beginning of function called initLump. Config is responsible for grabbing data from one of registers for use in 0x14/0x15 hooks. Mentioned data is EE memory offset, if data from 0x13 is 0, 0x14/0x15 don't apply.
0x14 Snowblind Engine specific fix. Applies to the end of function called initLump. Used in the older version of Snowblind Engine (Dark Alliance duology, The Bard's Tale, Fallout).
0x15 Snowblind Engine specific fix. Applies to the end of function called initLump. Used in the newer version of Snowblind Engine (Champions duology, Justice League Heroes, Combat Elite).

0x17 NFS HP2 fpu rounding fix. 
Check if a0 == 0x8000 (32768), apply config if true. Config is little bit more complicated than it should, emu flush all fpu regs to memory just to modify one field in altivec vector register.
When condition is met ps2 cop1 f08 register is modified from 0x40490FDB to 0x40490FDA, this result in next operations to end up as negative 0.0 (0x80000000) instead of just 0.0 (0x00000000).
Seems to trigger when loading of stage or loading of attract mode is close to finish or done.
0x18 Okami PAL specific hook. 
Check if opcode at 0x183F04 of EE memory is jal 0x183CB0 (0x0C060F2C). This is used to run additional hook patcher only 1 time.
Later it will be nop here. so it means that new hooks are already applied. So function will just return early.
if opcode at 0x183F04 is still jal 0x183CB0 (0x0C060F2C),
then patch addresses 0x183F04 (jal 0x183CB0), 0x183F34 (jal 0x183CB0), 0x183F3C (jal 0x183D18) to nop.
Finally adds 3 additional EE hooks. Emu addresses for ps2_netemu 4.70+

EE address | EMU address 
0x183F0C   | sub_46334
0x183F3C   | sub_45DA4
0x183D74   | sub_47B50

First hook is responsible for grabbing EE addresses from one of EE gpr register. Second hook perform few checks from data in EE gpr registers, and 
eventually store data from EE gpr registers on previously grabbed addresses. Hook 3 store one of previosly grabbed EE address on unknown part of memory.
Whole thing looks like HLE version of noped functions.
0x19 Burnout 2 
Copy lower 64 bits of $v0 r5900 register to lower 64 bits of $a1 r5900 register.
All that to make next opcode (hook address + 4) "beq $a1, $v0, addr" always true. Because $a1 and $v0 now have the same value.
This in turn skip CTimer::GetTimeSeconds((void)) in function CReplay::NextFrame((CDrivingControls *)). Worth to note that CReplay::NextFrame seems to be not related to replay per se, but to car physics.

0x0A Command Name: EE_INSN_REPLACE32
Command Data: uint32_t count, <List> (mode | offset, original opcode, replace opcode)

Command present only in the ps2_netemu. Maximum List Count: 32. Mode is first 4 bits of address field (Xyyyyyyy), can be either 0, 1, or 2. All known examples use this command in 0 mode, and modes 1 and 2 are here just for documentation purposes.

  • mode 0 - Replace 32 bit of EE memory. Params are EE offset, original opcode, replace opcode.
  • mode 1 - Write jr ra, li v0, xxxx to selected memory range. Params are EE memory start address, original opcode, u16 counter, u16 value for li, v0 xxxx
  • mode 2 - NOP memory at selected range. Params: start address, end address, unused (can be anything, but is required to align config).

Problem: Original opcode validity check is performed before testing config for special cases. Thus making mode 2 almost inaccessible.
Solution: We can patch that one line of code by the same 0x0A config. So if we want to nop region from 0x100000 to 0x100080, first we need to patch 0x100000 to 0x100080 opcode. So check will pass, "simple" as that.

0x0B Command Name: MECHA_SET_PATCH
Command Data: 1x uint32_t count, <List> {sector id, offset, sizeof present opcodes, replace opcodes, original opcodes)

Offset on the disc = sector id * sector size + offset + correction [see below]
Offset correction is based on selected read mode (not on media type):

CDRead requested block size (CD disc):

  • 2048 = Offset + 0x18 (skip 12 sync bytes, 4 of header, and 8 of subheader)
  • 2328 = Offset + 0x18 (skip 12 sync bytes, 4 of header, and 8 of subheader)
  • 2340 = Offset + 0x0C (skip only 12 bytes of sync data)

DVDRead requested block size (DVD Disc):

  • 2064 = Offset match, but only until the 349th sector. Otherwise is offset - 0x0C because that read mode see data as ID DATA (4) + ID DATA EDC (2) + Reserved bytes (6) + 2048 data + EDC (4).

"Offset + XX" for CD assume that you use Isobuster RAW mode. "Offset - XX" for DVD assume that you use Isobuster NON RAW mode
Special case is DVD read on very low sector, here you need to use exact offset without substrating 0x0C. Highest confirmed sector that don't use correction for now is 349.

0x12 Command Name: Unknown
Command Data: <List> (uint32_t count,

VU0/COP2 related multicommand. 

First 8 bytes of that command are special flags. Not quite sure about bytes 5-8 yet,
because at some point they are used to "andc" with first 4 bytes.
Some examples for first 4 bytes:
0x1000     = Run additional flag related code after every FMAC operation, VU0 only, COP2 do this by default.
0x2000     = Emit some additional code when lower opcode is fsset, this flag require 0x1000 to be enabled. VU0 only. 
0x100000   = When enabled opcodes like MSUB, MADDA, etc, do proper multiply first, then add/sub. When disabled (default) single opcode is used (vmaddfp / vmmsubfp). Not used in COP2 mode.
             Note: When this command is disabled, then "Accurate MUL" is skipped for MADDxx/MSUBxx regardless that 0x30000000 is set or not.
             Because there is no way to do correct MUL separately when altivec madd/msub is used.
0x200000   = Run some additional code in VU0 load/store opcodes (ILW, LQI, ISWR, etc.) Not used in COP2 mode.
0x400000   = Skip emu syscall 3 (3)
0x800000   = Skip emu syscall 3 (4)
0x4000000  = Enable type 2 config from cmd 0x12.
0x8000000  = Accurate VU0 DIV opcode, not used in COP2 mode.
0x10000000 = Fast Accurate VU0 MUL. Try to round mantissa. Opcodes like MSUB/MADD additionally require 0x100000 to be enabled, otherwise command skip them. Not used in COP2 mode.
0x20000000 = Full Accurate VU0 MUL. Use runtime from CMD 0x10, but for every matching VU0 opcode, including opcodes like MSUB for mul part.
             Opcodes like MSUB/MADD additionally require 0x100000 to be enabled, otherwise command skip them.

Selecting both 0x10000000 and 0x20000000 (0x30000000) work the same way as 0x20000000.
Keep in mind that you still need to use at least 8 bytes for cmd 0x12, just use 00 for bytes 5,6,7,8. 
Later bits are dependent on which subcommand we want to run.

Patch SPE 0 (IOP) program in local memory. Command search for absolute branches in LS 0x3A2C0 - 0x3A6C0 and patch first branch that match to "bi r127". That weird approach was probably used because spe program differ little bit between emu versions, so they don't need to update command on every new emu revision. Currently (4.75+) this command patch branch at address 0x3A3A4 (bra sub_2E600). This command takes partially unused value. Value 0,1 do nothing, values 2 and above run command. Doesn't matter is 2,4, or 10. Nothing will change in command behavior.

Default 1 

Make VIF0 commands MSCAL/MSCALF/MSCNT/MPG/FLUSHE non instant. By default every VIF0 command take 1 cycle, so it's instant.
This config give vif0 some timing sense.
When delta from config passed and vpustat vu0 bits are non 0 (so practically if vif0 is still running),
add 500 cycles and go on until next event test before doing anything on vif0.
This can also be used to ensure that next vif0 command won't run until delta from config passed.
Value from config is added to current r5900 cycles and vif0 will do nothing unless current cycles match new value.

0x42 Command Name: EE Overlay patch
Command Data: 2 main Params + patch data: uint32_t address, uint32_t count, opcode,opcode,opcode...

Applied on game start (more precisely while executing ps2 bios syscall 7 ExecPS2), if game overwrite selected part of memory, it will wipe 0x42 patch. See Special:Diff/67828/67858 

Start address can be (in theory) anywhere, but Sony used the 0xFF000 - 0xFFFFC range for this purpose.
Count is size of patch in 4 bytes opcodes. So 5 opcode patch = count 5.
Opcodes will be placed on selected address, we use only patch code, no need for original opcode.
Next opcode addresses are auto calculated (+4..) so we need to specify only patch start address.
Remember we need to jump to our new code, best way is command 0x0A with j (jump) opcode.
Also is important to add return jump if required. That one need to be added in our 0x42 patch.
Maximum opcodes count seems to be 0x3FF (1023 opcodes).
0x43 Command Name: Unknown
Command Data: 1x int32

Equal to command 0x40, but with Parameter: 

Command change GIF behavior by setting value at address 0x2F0 LS in SPU4, correct values are:
0 = Default
1 = More agressive changes (like 0x40)
anything other = less agressive changes
Code on SPU side check for non zero value, and in few places explicitly for 1 (ceqi rxx,rxx,1) without mask. 
Config have weird behavior. When there is no param, and config end (no more bytes after 43 00 00 00), then param 0xFFFFFFFF is set automatically.

depending on sys_info.video_mode & 0x200 is 0 or not.
Both 480 modes can be either I or P, so is something else, probably 59/60Hz.
This config possibly affect only in-emu UI, but this require testing.

Phantasy Star Complete Collection
0x46 Command Name: Enable L2H Improvement
Command Data: N/A

Performance related setting for titles using L2H (Local to Host, so called GS download (from GS to EE)) 

SMT Digital Devil Saga 1 - Crazy amount of GS downloads used to draw characters in-game
SMT Nocturne
Fatal Frame II

Other games affected (not in official config) 

Soul Calibur 2 - When looking at the sun
GT4 - When looking at the sun
Valkyrie Profile 2 - Similar situation to SMT DDS1, in Solde game literally do thousands of 30QWC downloads all the time.
Tak and the Power of JuJu - Fix freeze during loading of the Burial Ground level in the NTSC version. This probably getting lucky with VIF1/GIF timing, normally command is not supposed to fix hang issues.
0x47 Command Name: Enables XOR CSR
Command Data: N/A

Graphics related setting.
XOR bit 13 of GS CSR register (CSR.FIELD). Should fix fullscreen line corruption, maybe some interlacing issues. Long shot, but can possibly affect SCANMSK games.

0x48 Command Name: VSYNC Delay
Command Data: 2x uint32_t
  • First param possible value are 1 = No IPU, 2 = IPU, 3 = Anytime.
  • Second param is delay (in ms?), and can be also negative value.
    • Emu has standard presets for second param.
      • Agressive = 0x3D090 (250000 decimal),
      • Normal = 0x186A0 (100000 decimal),
      • Conservative = 0x4E20 (20000 decimal),
      • But other values can be used.
[SMT Digital Devil Saga 1] uses 1, 0x3D090
[Fatal Frame II] uses 0x2, 0xFFFFE69C (-6500 decimal)
0x49 Command Name: Unknown
Command Data: N/A

Skip part of code which use GS XYOFFSET_1 register, possibly ignore it at all. 

Trapt
0x4A Command Name: Unknown
Command Data: N/A

Change VIF1 command 14h MSCAL behavior to use 15h MSCALF (VIF1) instead. MSCALF behavior is the same as MSCAL, but also waits for PATH1 and PATH2 to not be active before starting a microprogram. This is hack, and MSCAL should be fixed instead to wait in queue instead of triggering early. 

Applies to the Snowblind Engine games. Fixes the rest of flickering textures.
Meant to be used in conjunction with the GX/SOFT Snowblind Engine's specific commands (double 0x01 and 0x23 combo).
0x4B Command Name: Redirect SAVEDATA by ID
Command Data: 2x uint32_t + ID: offset, int, char[] 
For proper config we need at least 2 (can be more if needed) 0x4B commands, one to enable redirect, one to disable.
First param is EE memory offset that when is hit enable/disable redirection.
Second param is used to select which card will be redirected:
  0x00 do nothing
  0x01 for SCEVMC0.VME
  0x02 for SCEVMC1.VME
  0x03 for SCEVMC0.VME and SCEVMC1.VME
  0xFFFFFFFF to disable redirection, and use original VMEs.
Third param is ID of SAVEDATA we want to use padded with 00 to match 12 bytes, or all 00 in disable redirect config.
Important note here is that config have own 00 00 00 00 terminator at the end. 
So after 12 bytes of ID we need to add 4 bytes of 00. That apply also to disable redirect version.
Under the hood config also setup 0x01 hook commands with 0x39 subcommand on selected addresses.
0x4C Command Name: Unknown
Command Data: 2x uint32_t + ID: offset, int, char[] 
Used to redirect to different ISO without game reset. First param is EE offset to hook, second param is some kind of mode selector, depending on that 
emulator later set mecha switch disc state:
  mode 0x01 = set disc switch state to 1 (on next mecha main loop it will emulate opening the tray).
  mode 0x02 = set disc switch state to 3.
  mode 0x03 = set disc switch state to 3. This state repeats because it work different way depending that emulated tray is closed or no.
  mode 0x04 = set disc switch state to 2.
  mode anything else = do nothing.
Third value is ID in big endian hex ascii (eg. NPJD12345), additionally 0x4C expect own 00 00 00 00 terminator. To eventually end redirection use 
another 0x4C but with (offset, 0xFFFFFFFF, 4 * 0x00000000 . This config have very similar usage to 0x4B, just redirect to different iso, instead to 
different MC. Currently is unknown that cobra patched emulators support that config properly, and swap disc thru 0x00 command seems to be easier.
This config don't work if 0x00 multidisc config is detected. Config under the hood setup 0x01 hooks with subcommand 0x3A
0x4D Command Name: Unknown
Command Data: 1x uint32_t

Param is floating point value. Default value 0. 

if Q in GS RGBAQ write is 0.0 or -0.0 then
    Q = Q | value from config
else
    Q = Q

Inside ps2_gxemu.self/ps2_softemu.self

There are hundreds of configs hidden in ps2_gxemu, and ps2_softemu self files. Internal config structure is basing on custom hash based on Title ID, internal memory offset pointing to place where true patch instruction is, and count of used commands. When disc/iso is started emulator search for configs, and if config for selected ID exist, then emulator apply it by itself. Is not perfect way of applying patches, because some games use the same ID, but different content. Good example here is Star Wars Battlefront II SLUS-21240, where some versions of game can refuse to work because it apply bad patch.

PS2 Title Hash Game Patch Type Data

Known Emulation Bugs

This list known bugs inside emulator code that make emulation inaccurate. Since those are only EE side bugs for now, ps2_gxemu/ps2_netemu/ps_softemu share the same issues.

Bug Description Known Affected Games
Missing Emotion Engine Data Cache emulation Emulating that is literally not possible without making games run at 3 fps. Fixed by patches to game image, or EE code. Instruction Cache (not Data) seems to be implemented, at least partially. Ice Age 2, DOA2: Extreme, Nascar 2009.
Branch delay slot violation not supported on EE Some games have Branch instruction inside Branch delay slots, this is not emulated correctly on EE (VU have proper emulation of that). This is patched in configs by rearangging MIPS code. WRC 3,4,Rally Evolved, one of Action Replay discs.
Unmapped write only EE memory (confirmed only for SIF) Reads/Writes to 0x2000000+ shouldn't throw bus error on dma transfers. Write should be performed as successful, memory should stay unchanged. Reads should return 0. Games developed by In Utero, while creating initial save file, send DMA where address is EE stack pointer. At the time of transfer start $sp is too high, and requested transfer size make MADR overflow above 0x2000000 at some point. This is game bug, and happen also on real hardware. Fixed by config.
VIF bugs There is no correct timing, and queuing for some VIF commands like MSCAL. Snowblind Engine games. Probably more.
XGKick is instant Some games expect to XGKick happen few cycles in future, on PS3 is done instant. Fixed by config 0x07 which delay XGKick by selected value WRC series, Wakeboarding Unleashed, TriAce games, World of Outlaws - Sprint Cars, Ty - The Tazmanian Tiger, dot Hack - G.U. series, and more
COP2 instructions are instant Some games rely on fact that COP2 operations can take some time, on PS3 emulators they are done instantly due to lack of correctly emulated pipeline Patched by rearranging mips code FFX, FFX-2, Ghost in The Shell SAC, Ace Combat series, Sprint Cars 1/2, Black, Run Like Hell, Everblue 2, Dragon Quest - Shounen Yangus no Fushigi na Daibouken, and many more
VU0 is not running in sync with EE core VU0 is running program "at once", which mean that VU0 run until it hits E bit. From EE perspective it looks like whole VU0 program run in 1 cycle. Games that expect VU0 registers to be changed from EE side while VU0 is running are broken due to that. Partially resolved using 0x12 command with 2/3 subcommands, or by code rearranging. 24 The Game, ATV Quad Power Racing 2, Twisted Metal Head-On, Primal, Ghosthunter, Rayman Arena, Rayman 3, Largo winch. All games using M-bit.
M-Bit not supported Emulator ignore VU0 M-Bit, that cause issues for games that need it to work correctly. This is done because there is no way to sync correctly running VU0 without sync with EE. Partially resolved on emu using 0x12 command with 2/3 subcommands, or direct VU0/MIPS code rearranging. Totally Spies! Totally Party, Mike Tyson Heavyweight Boxing, My Street, Crash Twinsanity, Marvel Nemesis, Panzer Elite Action - Fields of Glory, TriAce games (speed optimizations only), Super Monkey Ball Adventure, most Eko Software games, and many more.
T-Bit not supported on VU0 Emulator ignore VU0 T-Bit, that cause issues for games that need it to work. Note: T-Bit is correctly handled for VU1. Spiderman 3 set T-Bit, then do cfc2 from TPC (address where VU0 stopped). Since T-Bit is ignored, TPC is wrong. Value is later copied to CMSAR0, and program continue at wrong address. Well that's what should happen, but T-Bit also not signalize correct bit in VPU-STAT. Causing another issue, also in Spiderman 3.
Emulator do not update correct flag instances for COP2 while ending VU0 program on Ebit This cause few games to read bad flag status (not status flag!) on COP2. This is resolved on emu by forcing update of MAC flag on every STATUS flag read (by config 0x12), this cause slowdowns creating a lot of unnecessary operations. Driving Emotion Type-S, State of Emergency 2, The Getaway Black Monday.
Not updated status flag when VDIV/VSQRT/VRSQRT is done on COP2 Potential bad flag state can cause a lot of issues that are not related on first sight Yanya Caballista (already patched by custom config)
In corner cases emu select wrong block flags pipeline state (both VU0/EEonBE and VU1/VRC affected). This can cause various issues, mostly SPS, missing graphic, specific slowdowns, etc. Issue seems to occur when branch/jump delay slot have opcode important for flags calculation. Theory is that cached microprogram don't include modified flags state from delay slot instruction. So when already recompiled program is fetched from pool, it will miss one cycle in fmac flags pipeline. This can be crucial in games that rely on it. Tales of Legendia and Klonoa 2 set sticky flag bits to 0 and branch with sub.xyzw in delay slot (expecting that sub change status flag), Tamsoft engine games set sticky bits to 0 in branch delay slot, this was most ridiculous bug, because problematic branch was pointing to next opcode after delay slot, removing branch was enough. True Crime: NY is only known game where VU0 is affected by this bug. more..
CTC2 opcode write whole value to R register, while only 23 bits are writable. Rest is hardcoded to 0x3F800000. Can cause many weird issues like broken physics, broken graphics. PCSX2 was also affected [more]. The one game that is known to be affected, and is already patched, is Musashi: Samurai Legend.
CFC2 from R register should return only 23 lower bits. CFC2 from R on real PS2 return only lower 23 bits. Originally found out by PCSX2 team [more] and later confirmed to affect ps2_netemu in emu assembly. There is only one game that is known to be affected, Onimusha Dawn of Dreams.
Missing floating point result overflow/underflow detection (U/O flags not set) Since this affect all units (FPU/VU), many issues can occur. But in reality it seems to not affect any games. While this is easier to implement than on x86 system (full floats range, compared to ieee754), there is no way to do that by hardware way. Because SPU add/sub don't set those flags on single precision operations, and vmx have them disabled in spu compatibility mode. Superman Returns.
DMA between SPR and VU1 memory cause emulator panic. Currently cause is unknown. It seems that functions responsible for transfer don't check that VU is running. Manual state that dma can be performed only when VU is not active, and pcsx2 wait until VU end. Games affected in emulators on ps3 display this warning in pcsx2 if mtvu is enabled: "MTVU: SPR Accessing VU1 Memory". Affected games are fixed by rearranging code to do lq/sq loop instead of DMA. Summoner 2 (SPRfrom to VU1 data mem), Kaena (SPRto from VU1 data mem).
IOP SIF0/1 DMA IRQs can be disabled (masked), which is not true on real hardware. IOP interrupts 0x2A and 0x2B should always trigger. Fixed by patches to IOP code. Ps2_emu seems to be unfacted, probably handled on real hw in CXD9208GP. Knockout Kings 2001, DOA2: Hardcore.

Software emulation bugs

Related to the GS emulation issues mostly. Apply to the ps2_netemu especially.

Bug Description Known Affected Games
No mipmapping support Emulator does ignore the mipmap layers, probably for performance reasons. It is processing only the level 0 texture base pointer specified in the TEX0 register. There are games writing garbage data into that memory area, when the mipmap level is different than zero. As a result, a garbled texture is shown instead of a correct one. Ace Combat series, Ape Escape 2, EA Sports F1 series, Harry Potter series, ICO (psuedo volumetric rays), Jak and Daxter series, Nickelodeon Barnyard and Nicktoons Unite (very strange implementation), Ratchet and Clank series and more.
SCANMSK register ignored Emulator does ignore the SCANMSK setting responsible for restricting the drawing primitives on the odd or even lines. It is used as a fake transparency effect in some games by merging the two display circuits. Metal Gear Solid series (water and reflection effects), Gran Turismo series (ghost cars), Raw Danger! (depth of field effect)
Missing PCRTC feedback write support PCRTC feature that writes back the image to the frame buffer is not supported or broken. Additional RGB to YCbCr conversion could be performed there. Xenosaga Episode I: Der Wille zur Macht (black and white cut scenes)

TitleID/DiscID in ps2_netemu.self

There are 193 titleIDs listed inside ps2_netemu.self. More precisely, into XPARAM2.ELF file of PS2 Bios included in ps2_netemu.self. XPARAM2.ELF is called by OSDSYS, then ID check is performed. If title ID match to one of included in the table, different IOP emulation settings are applied. There are internal flags related to every title ID included inside file, still unknown what they do. Also some arguments, in plain text. File in real ps2 is introduced in SCPH-750XX models so exactly when DECKARD Power PC chip exchanged original IOP chip. This can explain why it is still in PS3 netemu bios. Because PS3 it is ppc that can need the same/similar flags.

Original PS2 bios include similar list file called XPARAM.ELF, but Title IDs there are not the same, although some of them exist on both lists.

Other game patches (unofficial)

There are other unofficial ways to patch the PS2 games such the pnach format, or the widescreen patches that allows 16:9 screen output for some games by hex editing the ISO, or by applying ppf patches. Games work fine on PS3 with same compatibility like before patching. Also some 480p (aka progressive scan) patches work fine. http://ps2wide.net/

The problem of this methods is the patch is applyed over the ISO and is modifyed permanently, but this problem can be avoided in PS3 because that unofficial patches can be "ported" to the official config format to be used by ps2_netemu.self, by using the official config format the settings and patchs from the config file are applyed "on the fly" and the ISO is not modifyed

ps2_title_brute code

A script to calculate cdvd key magic used in ps2emu, gxemu and softemu from given input title id. On real PS2 this value seems to be stored at 0x1F402020-0x1F402024. It contains code for bruting as well. Just call gen_sum with the title id in a specific format to get it. 

title_ = "SLUS_200.73"
