Note: Apparently ps2_gxemu SPU layout changed at some point (maybe ps2_emu too), and above table is not accurate for latest emu versions.<br>
0-6 layout for ps2_gxemu currently look like this: IOP, SPU2, IPU, VU1, EEDMA, GSGIF, UNK(probably isolation).

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.

===Config file examples (for netemu)===
<!-- 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 -->
 
====Official PS2 Classic====
See: [[PS2 Official Configs]]


====Official GXEMU/SOFTEMU extracted====
See: [[PS2 Official Configs]]


==== Custom Configs ====
{{Boxcomm|id=0x00|name=Title ID Enforce / Multidisc config|data=1x String in format: ABCD-12345}}
See: [[PS2 Custom Configs]]
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.

====Inside ps2_emu.self====
Most of the hooks availables in netemu command 0x01 are fixes for a specific game, or a game engine<br>
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.
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.

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).

|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.

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.

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):
*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>
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,
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.

{{Boxcomm|id=0x14|name=VU1 transform ADD/SUB|data=N/A}}
When enabled ADD/SUB VU1 opcodes are processed differently on recompiling/translation stage. Seems to be very specific hack, most likely not usable outside of THPS 4+ engine games. <br>
Note: This setting affects only VU1, and only ADD/SUB. All other opcodes like ADDi,ADDq, MSUB, ADDbc, are not affected.
 
{{Boxcomm|id=0x15|name=Unknown|data=1 Param ( <1, >1 )}}
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.

{{Boxcomm|id=0x1F|name=Unknown|data=1x uint32_t}}
Default 1
Make few VIF0 commands (MSCAL, MPG, etc.) 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.

Is worth to note that 0x3C is default multiplier even for PAL titles, so is not stricly related to framerate,
but to vsync counters (where 0x3C is still wrong anyway..). Result of multiply is also compared at some point to vsync delay value.

This drastically reduce emitted code size, and practically disable iCache emulation. Additionally CACHE IXIN/IHIN opcodes use different very long code path (this can be skipped with cmd 0x03).
Option two default value = 0, when set to 1: Emit some kind of check for current r5900 PC with possible trap (tw opcode) at the end. 1 is valid only when option one is 0.

Used by debug menu to print config revision. While every official and unofficial config use it, command is not mandatory. Debug menu will just print '''None''' as a config revision if command is missing. Official configs use this as a kind of debugging info to know minimal required emu revision. While unsupported commands will be skipped by emulator, emulator can't know how long they are, this can result in reading cad data from config in next loops.

{{Boxcomm|id=0x42|name=EE Overlay patch|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).
 
{{Boxcomm|id=0x43|name=Unknown|data=1x int32}}

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.

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.

{{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 partially unknown, seems to be size of next param to read * 4 (3 in known configs), or 0xFFFFFFFF for disable redirect command.
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.
 
{{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 ID size * 4. Emulator do some checks here, safe value is 3 (3 * 4 bytes), 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.

| 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)
