===Getting Playstation 2 Software Emulator working===
 
Method (on Firmware 3.55, without! Cobra-USB Dongle or Downgrade) for all consoles (fat & slim).
 
1. Replace following files on your consoles /dev_flash/
    with the ones included in this archive
    p3dwik-ps2compatfiles.rar
2. Get into Factory Service Mode (FSM Tool/Dongle)
3. Insert your Original PS2 Game Disc
4. It will run.
 
Note: Backups wont work. You're getting the compatibility of the 2.60 software emulator with all of its bugs.

====boot_ps2====
http://foxbrew.org/ps3/otheros-utils/boot_ps2.git <br />
http://www.multi...upload.com/QKK7ETPHXZ boot_ps2-src.rar (1.43 KB) <br />
http://www.multi...upload.com/YCZ63Y6TQ5 boot_ps2.pkg (69.17 KB) <br />
 
any chance of having this package resigned for 4.21 cfw? might be useful to see if it'll boot ps2_netemu.self LPAR.
 
(can boot ps2lpar, but also petitboot if otheros installed! 50:50 chance)
 
[http://rghost.net/42586725 boot_ps2 4.xx eboots.zip (153 KB)] <br /> installing 3.55 pkg and replacing the eboot and editing the sfo should work.

==== Service Mode in relation to PS2 emulation tests ====
<div style="float:left; width:25%;">
* Service mode resets display settings (on default it uses HDMI with composite on MultiAV connector) - this means that users of Component cables can get garbled screen / no display output (in tests below, the primairy screen) unless using composite wiring/screen (in tests below, the secondairy screen).
{| class="wikitable" style="font-size:x-small;"
 
|+ ps2_emu.elf (decrypted)
* Service Mode also resets user presets like disc autoboot, so it needs to be disabled again if needed.
! Firmware !! Bytes !! MD5 !! <abbr title="Revision">Rev</abbr> !! <abbr title="Maximun number of supported commands">Comm</abbr>
 
* Any made Virtual Memory Cards previously will be removed and you will have no access to them, nor be able to create one.
 
* When PS3 is switching to PS2, connection with Sixaxis / Dualshock 3 will be lost (even when using USB wired connection). In some cases easily resyncable by using PS button, but in other cases the leds stay off and the controller cannot be used (until ps2 mode is exited or console rebooted)
 
* As a workaround for above wireless controller issue, you can use an USB2PS2 converter and connect an old PS2 / Dualshock2 controller.
 
==== tests on 2000 series PS3 Slim ====
Testplatform:
SKU: 2000 series slim (minver 2.70)
Firmware: 3.55 'Rogero 3.4' mmap114+peek/poke but no SS-patches
Memorycards: MC:PS1 in slot1, MC:PS2 in slot2.
Mainscreen: Component+Composite 576i+P/720i+P//1080i
Sec.screen: Composite 576i
48 titles tested (PAL disc on PAL SKU) // [[User:Euss|Euss]]
 
* Without Factory Service Mode : gives "Incompatible Data" when inserting PS2 disc
 
* When enabling [https://web.archive.org/web/*/http://ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher] without factory service mode (patch4 set as http://pastie.org/private/jp8zhvuocjz95cfrjm0uzg) : no changes in XMB:Game (still only PS upscaler/smoothing, no PS2 mention at all)
 
* When enabling [https://web.archive.org/web/*/http://ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher] without factory service mode (patch4 set as http://pastie.org/4355919) : gives XMB:Game PS2 smoothing/upscaling options, it also make an inserted disk to be seen as PS2 format. Still same problem of ¨incompatible title¨ and loss of BT/settings. Also after returning to XMB, it no longer sees the disc as PS2 format but as incompatible data (which suggests the lv2 patch is undone, as lv2 is reloaded when returning from the ps2 lpar)
 
* Using [https://web.archive.org/web/*/http://ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] without factory service mode : no resetting of date/time/displayoutput (still output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation), and after a long while comes up with the message that the title is not compatible and that the ps3 needs to be updated (Basic nag screen that is on BC PS3s when inserting a noncompatible title).
 
* With Factory Service Mode enabled (there are no Xmb options to combinetest with [https://web.archive.org/web/*/http://ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher] or [https://web.archive.org/web/*/http://ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg]): gives ´PS2 disc´ detected at disc icon, but starting gives: resetting of date/time/displayoutput (effectively disabling my mainscreen), then all connection to any bound bluetooth device is lost, even when connected via USB (needs multiple PS button reactivation), and after a long while comes up with the message that the title is not compatible and that the ps3 needs to be updated (Basic nag screen that is on BC PS3s when inserting a noncompatible title).
 
In short: [https://web.archive.org/web/*/http://ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] and Factory Service Mode seem to enable simulare (it tries to boot it) while [https://web.archive.org/web/*/http://ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives you more options e.g. using [https://web.archive.org/web/*/http://ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher].
Perhaps hardswapping out all the dev_flash ps2 emu files for the same software only emulator would circumvent the 'incompatible title' message.
 
 
==== Second test: FW 2.70/3.15 ====
Silent Hill : gives disk icon "unsupported data" and error message like "This model of the PS3 system is not compatible with Playstation2 format software" when run via disc icon. Using [https://web.archive.org/web/*/http://ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives title not supported error message like "This title is not currently compatible with the PS3 system".
 
==== Third test: FW 3.55 OtherOS++22GB (with SS Patches) ====
Silent Hill : gives disk icon "unsupported data" and error message like "This model of the PS3 system is not compatible with Playstation2 format software" when run via disc icon. Using [https://web.archive.org/web/*/http://ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives blackscreen lockup, not reacting on PS button, or powerbutton, requiring removing powercord.
 
 
===== considering titles to test =====

* http://tortuga-cove.com/forums/viewtopic.php?f=57&t=530
* http://us.playstation.com/support/compatiblestatus/index.htm
 
These have no listed issues:
* Half-Life
* Hulk
* Medal of Honor: Frontline
These have minor issues listed (but should still play):
* Silent Hill 3
* Second Sight
 
==== tests on CECHC04 (partial BC) ====
on 3.41 or on 3.55 in normal XMB mode (no disc icon in XMB): boot_ps2.pkg gives no resetting of date/time/displayoutput (still output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation), and after a long while comes up with the message that the "The system was not turned off properly" as if it had experienced poweroff and from there booted back to XMB. It then returns to the XMB, but first gives an error screen, mentioning 0x80028F17 occured (''PS2 mode error 0x80028F17 "An error occurred during the start operation (80028F17)," PlayStation 2 disc Boot Error, also related to PS1 PSN games.'')
 
on 3.41 or on 3.55 in normal XMB mode (disc icon in XMB): boot_ps2.pkg gives resetting of date/time/displayoutput (no output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation). The game is playable on secondary screen, and exit to XMB with holding PS button goes without 0x80028F17 errors, but does give the "The system was not turned off properly" error.
 
no disc icon:
* Medal of Honor: Rising Sun
* Half-Life
 
disc icon:
* Hulk
* Second Sight
* Silent Hill 3
 
==== Renaming ps2_netemu to ps2_emu ====
 
Tested renaming ps2_netemu.self to ps2_emu.self on CECHB01/rogero 4.21 with dev_blind mounting via multiMAN but boots to black screen, no disc activity, but controller shuts off and is synced. No PS button menu or anything.
 
boot_ps2.pkg boots, no disc activities, then throws up an error depending if the file is resigned for 4.21 or not. (tried both a resigned and the existing version)

==== Tests on NON-BC CECHP01/NTSC-U (Firmware 2.60/boot_ps2.pkg) ====
<!--
<br>
====Horizontal style (all ps2 emu types together)====
<br>Amplitude - Intro prompts are completely glitched, unresponsive to controller input.
Hidden, by now is not posible to know how many columns are needed for the firmware versions to place all emu types info together in a single table using this style
<br>Backyard Football 2007 - Graphical glitches during menu and gameplay. Frame rate is okay.
<br>Boogie - Intro FMV runs very slow, fails to recognize input after the title screen.
<br>MLB 08: The Show - Intro videos run smoothly. Menus load with no issue. Gameplay is extremely slow with graphical glitches. Network configuration utility is completely garbled.

==Hidden/Inaccessible menu in ps2_emu==
 
Apparently PS2EMU (CECH A/B) have some hidden menu that is able to print IOP configs from bios (XPARAM.ELF), i didn't found way to get there, my only idea is replacing other menu with that one in jump case at 0x5D980 (emu around 4.78). Case 21, and 22 is what seems to be hidden menu.
More info about printed data: https://www.psdevwiki.com/ps3/PS2_Emulation#TitleID.2FDiscID_in_ps2_netemu.self
 
==Crazy Taxi check==
Emulators ps2_netemu, and ps2_gxemu (maybe others too), after calculating game hash perform compare check to 0x2BD12D81ED.
ID match US release of Crazy Taxi. This id is kinda special, because Swap Magic CD version, and some other Datel products like Action Replay use Crazy Taxi TOC in their retail discs.
Is known that they literally ripped part of disc (with key/logo, and TOC), and frankesteined it with own products.
So mentioned check first compare hash, and if that match, then run function that perform another check at disc sector 267559 (0x41527), so exactly where main executable is.
I didn't figured out what next, but this is probably anti AR/Datel/SM check. What's weird, there seems to be nothing for TimeSplitters2 which if i recall correctly was used for DVD version of Swap Magic.
<br>There is also check for 0xE794CCB06D  PCPX_980.42  Minna no Tennis entry, emu also refuse to boot it, and throw the same error as with SwapMagic/SCED discs.

Notes:
N commands handling differ a lot from pcsx2, doing that correctly is important for emulation.
Read model number return SCPH-50000 while returned mechacon version is (not existing?) 3.9.
This model should return Dragon mechacon rev, so 5.0 and up.
Returned ConsoleID is 00 00 00 00 00 00 00 00 00, this can be issue in corner case where game additionally check for non zero result.
Returned iLinkID is 00 00 00 00 00 00 00 00 00, this break Time Crisis 2,3, and one of Armored Core games on pcsx2, surprisingly netemu run them fine.
Every "mechacon_auth" command return zeroed result with different size. Only exception here is 0x81 which return 1.

{{spoiler|Purpose and style of the table (info only useful for wiki editors)|
This table was intended to replace the small one for netemu command 0x3D inside the huge table of config commands in frontpage, i realized there was a lot of duplicates inside but i did not wanted to mess around with the original table, and this talk page was saturated of text so i made it in my user page and now is moved here, is cute and small but is not definite though, lets say this one is the "vertical version" of it, but what i really want to do is to display the info in horizontally and to add together all the info from the other .self versions of the ps2 emus, something like the experiments done here [[Talk:PS1_Emulation#PS1_Emulators_versions_.28experimental_table.29 | PS1 table tests]], i like this one too though so probably i will made another one for the "horizontal version"

*Notes
**The colors used at the cells of the left column in the table are just temporal, later willl be needd to decide if using them, how many to color, and the color palette used in them... by now works a bit as an small hint of the complexity of the commands, and a rought way of grouping them
 
{{spoiler|Purpose and style of the table (info only useful for wiki editors)|
This one started as a notepad to compare the command IDs from gxemu and netemu, time ago i was thinking in adding some info in the huge table for config commands in frontpage (more eyecatchig, or noob friendly, or adding some mark to the commands to differenciate them in groups by its purpose), when i started making this table i realized it was posible to display all commands together in a 1080p PC monitor and that was very cool because it can be used like a "cheatsheet" when researching about this commands (for a fast compare, also remember wiki allows to print pages), the table was not intended to replace the other in frontpage, there is some info in the other that is not here, and here there is some info here that is not in the other (and this is a problem), what happened is this table started growing and at the time of moving it here (2017 november 4) it reached some "maturity", is at a point where can be done two different things with it, we can step back and simplify it (by removing the columns at right and the redundant info with the table of frontpage), or we can continue expanding it by adding here the info of the other table in frontpage, note this table right now is splitted horizontally but if we join it together in a single vertical table there is a lot of room to add more info, so it can replace the table in frontpage potentially at some point (not yet), i dont have a clear view of which path is better to follow though so by now i think im not going to modify it much more, is better to focus in filling the info inside it and continue rushing with it to see how it grows

1000F800 to 1000F8B0 seems to be some fake regs for testing purposes. Probably not existing on real PS2. Addresses not described below are handled as a unk rw. Which mean they return 0 on read, and do nothing on write.
</div>
* 1000F800 do nothing (blr). Have own handler, which suggest it was used for something earlier. [r/w]
</div>
* 1000F810 get current ppc time base using mftb opcode, if tb == 0 then loop until its not. Could be useful, tb is used also in scheduler. [r only] 
<br style="clear: both;" />
* 1000F820 return "DrJock TV Quiz P" [r only]
* 1000F830 return "hD bags few lynx" [r only]
That make string "DrJock TV Quiz PhD bags few lynx" - This is perfect summary of Sony work. Since correct pangram should use "MrJock". So even here they made mistake.
* 1000F860 seems to return halfword of current pad state (0xFFFF if there is no button input currently). [r only]
* 1000F880 return hardcoded value of 0x4457, which match emu revision i'm working on. Can be just coincidence. [r only]
* 1000F8B0 return unk value. Seems to be related to fe spe. [r only]

Addresses above ARE NOT the ones in emulator memory, this is local storage address in IOP SPE program!
Opcodes LWCx 0-3, and SWCx 0-3 are not supported at all.
Same goes for general COP 1-3 opcodes, but those cause COPx unusable r3000 exception.
While LWC/SWC are triggering bad opcode exception.
Not sure if LWC0/SWC0 should be allowed.
COP0 is working in PS2 mode, so those probably shouldn't cause exception.
At the second hand i don't know single IOP module that use that instruction.
</pre>
 
This is unconfirmed by any code reversing for now, but IOP emulator print messages like:
Cache write (IOPADDR/LSADDR/SIZE)
Cache read  (IOPADDR/LSADDR/SIZE)
ERROR: Double ICACHE fault
Which suggest that instruction cache is emulated for IOP. Making this (ps2/gx/net) emu only PS2 emulator that support cache emulation for IOP. For now even most ps1 emulators lack of that feature, and none of known PS2 emulators do that (including Pcsx2/Play!/Dobiestation). With this we can safely assume that also load delay slots are handled correctly here. Unrelated, but is hard to believe that someone implemented icache, but not load delay slots. Which again make it only known emu set that support this afaik.
 
===EEDMA on SPE3===
That one is one of most misleading names in whole emulator.. <br>
DMA channels are handled in:
*0 - VIF0 on PPU only
*1 - VIF1 dma, and VIF1 hw reads/writes including fifo write are handled in SPE3 (EEDMA)
*2 - GIF dma handled in SPE3 (EEDMA) incl. fifo write, but most HW reads is not handled here
*3 - IPUfrom dma, and whole ipu HW r/w is handled by SPE6
*4 - IPUto dma, and whole ipu HW r/w is handled by SPE6
*5 - SIF0 dma is handled in PPE, and SPE 0 (IOP)
*6 - SIF1 dma is handled in PPE, and SPE 0 (IOP)
*7 - SIF2 dma is handled in PPE, and SPE 0 (IOP)
*8 - SPRfrom dma is handled on PPE only it seems
*9 - SPRto dma is handled on PPE only it seems
Additionally EEDMA handle VU1 code writes/reads, VU1 code is stored at 0x1A000 of LS in big endian. Only VU1 code, VU1 data is handled by SPE2 (VU1), and any VU0 r/w is handled by PPU only.<br>
So is more like "Close to GS" DMA handler.
 
"EEDMA" is also responsible for handling VIF1 commands, including UNPACKs. In SPE memory structure responsible for that is starting at 0x1910 (0x00), and last entry (0x7F command) is at 0x9810. This make 100 bytes per "slot" for command information, like pointers to registers, masks for unpacks, pointers to function responsible for commands handling, etc. (more info about VIF cmds: https://psi-rockin.github.io/ps2tek/#vifcommands)
 
===VU1 emulation on SPE===
VU1 SPE program starts at 0x4000 of LS. Start function is responsible for loading all 128 spe registers with values from memory starting from 0x4230 of LS for r0, ends at 0x4A20 for r127 (r127 is trashed literally in next opcode after that...). This should result in all 0 value regs, excluding r0 which will be set to float(1.0, 0, 0, 0) like ps2 vf00. After that function notify PPE side that its done, and jump to 0x8000, here fun begins. SPE program now clear LS memory from 0x0000 to 0x7FF0, this include VU1 data mem that is located at first 0x4000 bytes. What's more important function that we started at 0x4000 will be deleted. Yup, self modifying code on SPU (good luck for eventual emulator that will try to run ps2_netemu).
<br>
When I disassembled VU1 SPE program, i noticed that real code is really small part of that. Not much to run real VU recompiler/interpreter.
Then i found out something impressive in my opinion. Real deal is that real code delivered to SPE is created on PPE dynamically based on real PS2 VU1 code. Due to similarity of SPE with VU requested in IBM by Sony at design level, there is no VU1 interpreter or recompiler per se. Emulator take VU1 code, dismount it to parts by OP field types, and reassemble into ready SPE code using ready hex templates. I'm not familiar with professional naming of that operation, but its like ahead of time translation of code. So when VU1 code reach SPE is already translated to SPE opcodes. In other terms, SPE responsible for running VU1 is really running VU1 code in some way.
 
In latest ps2_netemu function responsible for translating VU1 code into SPE ready code is located at 0x13C69C
<br><br>
SPU registers always follow this layout when VU1 is running:
*r0  - r31 = vf00 - vf31
*r32 - r57 = vi00 - vi25 (vu ctrl regs above vi25 are mapped to vu0 anyway)
*r48      = ACC (accessible from VU0 as vi19)
 
Additionally ppu can access those regs with addresses 0x3000xyy0.
Where x is 4,5,6, or 7 (mirrors), and yy is reg number in hex.
*0x30004100 = vf16
*0x30004200 = vi00
*0x30004350 = I register (vi21)
etc.


Is worth to note that ppu is not accessing spu regs directly, instead 0x3000x000 is mapped to 0x3F000 of vu1 local store. On real PS2 hardware regs are accessible only when VU1 is stopped so program just dump regs to that location on every vu1 stop (ebit/tbit/force break).
===ps2_netemu command 0x1===
This mapping is added specially for VU0 which can access VU1 registers by use of memory address, when vu0 recompiled program run ppu always load 0x30000000 to r1 to compute address if needed.
There are some additional internal patches using CONFIG cmd id 0x01, using subs not available in 0x3B list
 
condition: 0xBBB5F800, 0x3B949C00, 0x42133A90
===IPU SPE6===
setting:  
====IDEC start code detection====
  0x18E1F0, sub_4670C (4.70)
IDEC perform compare to 0 while starting to search code, but not check that required bits are even available in stream.
  0x348EC8, sub_44338 (4.70)
Buffer is not refilled when there is more than 0 bits available (function proceed even if there is only 1 bit available). Next compare whole word to 0, which is wrong thing to do. Specially that whole word can be not even available at this point. More over there is no check that at least 8 "0" bits are in stream that way. So start code detection is totally broken. Surprisingly this seems to be handled properly for BDEC..
This probably break Onimusha DoD, and many other random games.
====IPU skip mpeg hack====
There are some leftovers of SKIP MPEG hack in SPE 6 (IPU), i'm not sure that is still available.
 
===SPE4 and SPE5===
And SPE7, because someone there forgot it doesn't work in retail. :P First thing is that emulator do a lot of setup for SPE7, including creating virtual address to access it (0x40380000 - 0x403BFFFF). Only thing that seems to be missing is actually starting that SPE.
 
SPE4 (FE) have a lot of PS2 GIF related code, GS downloads function in PPE check something there (BUSY? BUSDIR? DL ready? bit), and if that bit is not 1 loop for 1000000 x 4 cycles and check again. That spe is also place where GIF_TAG# can be read, so last processed tag on GIF unit. That was greatest hint to be honest, there is no reason to send it there if is not processed there. This is also where 0x49 and 0x4D config commands go. And surprisingly they are not really related. But fact is they go thru same parser on SPE side. 11, and 12 from those commands are subcommand on SPE side. 11 take no args that's why 0x49 send 11,0,0. 12 take 1 arg, and that's why 0x4D send 12, param, 0.<br>
SPE5 (BE), well i didn't reversed that one too much. But it seems to have relation with "FE", and with RSX. This is only speculation but it seems that FE and BE are FrontEnd and BackEnd for GIF/GS emulation tandem. My first idea was BlendingEngine, but that doesn't seems to be the case. Well those 2 need more work.
 
==SCANMSK on ps2_netemu==
Apparently SCANMSK is not really ignored, GIF process it, update, etc. So is rather not implemented in later parts of code (GS emulation), or this is some other bug. I guess this GIF code is shared with ps2_gxemu, so maybe it is really missing processing on software GS emulation in later stages.

Both HDTV modes (0x51 1080i and 0x52 720p) crash the emulator. 0x53 576p mode does not, but the image is squished and displaced (looks like the DW is 2560, instead of 1440 and I cannot find any reliable documentation about this mode). Tested by forcing the values in the sceGsResetGraph function.
===ps2_netemu command 0x12===
* None of released games support 576p, so they probably didn't bothered. Afaik that mode is not really used for anything in PS2, like some leftover after testing, or something. I remember that older PS2 don't support it at all, so maybe it was planned as new feature? Also does forcing 480p work? I remember that 480p patching from Managunz gave similar result to what you described for 0x53 mode. But maybe its just broken feature in Managunz itself, i never tested manual patch. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 06:15, 29 March 2022 (UTC)
** Only the 2.20 BOOT ROM versions and PSX DVR BIOSes support that mode. But in the netemu, I think this mode is not compatible with the real PS2 one. It looks like a regular PAL (0x03) mode to me with a progressive support (SMODE2 INT field set to zero sends correctly a full 576 frame, instead of 288 lines with a PAL 0x03). Judging by the GS DISPLAY registers of OPL's 576p setting, the parameters of this mode should be more similar to the 480p mode than 576i on the real hardware.<br> You are right, it is actually the same case with the forced 480p through sceGsResetGraph. If you force this mode and leave the NTSC output buffer sizes, you get a horizontally magnified image (because the MAGH bit is switched in the register and the requested DW is bigger (2560) than expected (1440)). It could be related to the PCRTC/DVE emulation (maybe conversion of VCK units to pixels, I do not know how it does look like on the PS2). At least the parameters of 480p mode seems to follow the correct specifications, in contrary to the 576p.<br> Anyway, forcing the 480p mode in the netemu is not needed at all (apart from the issue mentioned earlier). Even using the interlaced modes, it does output a progressive frame with the full height front buffer games. With the half height front buffer games, the deinterlacing quality is pretty good in my opinion, as long as the 50/60 fps is maintained.--[[User:Agrippa|Agrippa]] ([[User talk:Agrippa|talk]]) 18:03, 30 March 2022 (UTC)
=== Widescreen support ===
If the game does retrieve the widescreen flag from the GetOSDConfigParam through the scescfGetAspect function, the results are as follows:
* Upscaler turned off: widescreen flag set by BIOS,
* Upscaler turned on - Normal setting (keep original aspect ratio): no flag is set,
* Upscaler turned on - Full screen setting: widescreen flag set by BIOS.
Assuming the PS3 is connected with the HDMI cable and all HD resolutions are ticked in settings. Probably the widescreen support with the upscaler turned off is dependent on the connection and the PS3 resolution settings.

Playground discussion, unsure about clrlslwi  r11, r0, 16,3 result


===Remove PCRTC Blur for Netemu===
<pre>
Adds new config 0x4F (no param) which disables PCRTC blur offset which many games use. Patch additionally changes debug menu entry XOR CSR to NO BLUR setting. XOR CSR from file CONFIG is unaffected and still work as expected. I decided to add this entry in menu because it's nice way to compare how good this setting is when game use blur offset. While games which need XOR CSR have very obvious screen corruptions so there is no need for "live" view for it. New config obviously not work on HEN, but CONFIG files which include 0x4F work fine on HEN, command is just skipped, this keeps configs compatible with all current hacks. Big thanks to mrjaredbeta for testing all of this!
Syphon Filter The Omega Strain
Under the hood code compares DISPLAY1 and DISPLAY2 registers and when DX and DY difference is not greater than 6 it mirrors DISPLAY1 to DISPLAY2. Many checks are added to prevent false detection: PMODE need to have enabled 2 circuits, any of DISPLAY registers can't be all 0's, etc. Detection also works for different DW/DH, for games like Soul Calibur 3. Results really vary per game, many games stays unaffected because they modify OFFSET by GIF 0x18/0x19 commands. Good example of game that is nicely improved is Kingdom Hearts 2.

===Display current PC/RA values for r5900===


Require '''ps2_netemu''' with 3141card patches to display temperatures (every current cfw have it). Mod update values in crazy interval, this is intended. Because mod is used mostly to figure out when game stuck on specific loop. But this can be easily modified to allow less frequent updates. Please note that PC and RA update only when recompiler registers are flushed to memory, luckily for us this happen on every r5900 branch test.

Sony is blocking every game which id from SYSTEM.CNF starts with S, and 4th character is D (SLED, SCED, etc.). When demo is detected sys_stat is set to error code, and emulator return to XMB. Patches here remove that restriction. Apparently ps2_emu don't have that check, probably because there was no need for it (compatibility reasons i guess).

===Extend config table by 50% in ps2_gxemu===
<pre>
Patch increase config slots count from 0x314(788) to 0x49E (1182), so exactly 50% more than before. Patch is dedicated for advanced users, and there is no profit of using it if we don't plan to add any new configs.
Primal
We are abusing fact that emulator isn't compiled by usual "GameOS" PS3SDK, and pointers are 8 bytes. Also fact that compiler to keep everything aligned is forced to add 4 zeroed bytes after config count.

8 bytes for hash, 8 bytes for pointer, 4 bytes for count, and 4 bytes of align to make data 0x18 sized. Without that PPC64 will throw exception because that data is read in a loop, so next read will be 8 bytes hash from xxxxx4 address.
type 2:
Sony (LV2/emus/guestOS) compiler isn't aware that emulator need really only 4 bytes for pointer, we have unused 4 bytes. Plus 4 bytes at the end used as alignment.
*0x20C | counter
*0x210 | 1st value: 0x15F      -> only gets compared, if passed check 2nd value
*0x214 | 2nd value: 0x2C6FBD8D -> only gets compared, if passed use *0x218 + *0x21C
*0x218 | 1 ( = count - 2)
        *0x21C | ptr to 3rd value *0x2AC (0x367)


Now:

hash      00 00 00 FF FF FF FF FF
pointer  00 00 00 00 FF FF FF FF
cmd count FF FF FF FF
align    00 00 00 00 (previously we thought that is terminator)


Compacted:
====type 3====
hash      00 00 00 FF FF FF FF FF
pointer  FF FF FF FF
cmd count FF FF FF FF


We have reduced size from 0x18 to 0x10 for single title without losing any data, free 1576 bytes to use :) .
<pre>
After that i wrote small dumper that allowed me to edit table in easy way to recreate new table with empty slots.
Example Primal
Hardest part behind us, now just patches to respect new table elements size, and we are done.
*0x11B4| counter
*0x11B8| -1 -> 0x399B60?
*0x11BC| 0 -> 0x399B60?
*0x11C0| ptr to *0x2C4 values
*0x11C4| count (2)


4.88.2 Evilnat ps2_gxemu.elf offsets:
r11 = r0 & 0xFFFFFFF = 0x10399B60 & 0xFFFFFFF = 0x399B60
0x6F938: 38 00 03 14 --> 38 00 04 9E  (increase loop count)
0x10399C18 & 0xFFFFFFF = 0x399C18
0x6F950: 39 29 00 18 --> 39 29 00 10  (decrease step incrementer)
0x6F968: 79 59 2E A4
          79 5A 1F 24
          7C 1A C8 50
              -->

          60 00 00 00
          7B 20 00 20                  (change way of config data offset calculation)
0x6F978: EB EB 00 08 --> 83 EB 00 08  (load config data pointer as zero extended word, instead of doubleword)
0x6F998: 80 0B 00 10 --> 80 0B 00 0C  (change load offset for config count)
0x6F9DC: 7D 3A C8 50 --> 7B 29 00 20  (change way of config data offset calculation for config with 2 or more cmds)
0x6F9F8: 80 09 00 10 --> 80 09 00 0C  (change load offset for config count)


For now we can add some configs to table, and use rest of new zeroed space to store configs itself.
r3 = r31 >> 28 = 0x10399B60 >> 0x1C = 1
Alternatively we can use whole new space for extended table, and use language strings for configs itself. But that make things "per region" which i don't like. All that without removing or editing any existing config.

Patch is for LV1 file, should be 4.75+ but it's based on 4.78 LV1 file. '''Don't try to modify your LV1 without hardware flasher!''' This patch enables ability to get fan readings and to set fan speed and policy.

Script for IDA to dump SPE programs from PS2 emulators, don't work with ps2_emu. Script is basing on SPE program names to find correct offsets. Due to that is will miss any SPE program which name is not listed inside script. Tested with ps2_gxemu/ps2_softemu/ps2_netemu.

== Random ps2_netemu notes ==
 
* Emulator not only patch SPU programs on init, but also patch own PPU code. Which is hard to understand when you can just make changes in source code... eg. 0x1F128 - 0x1F134 in latest emu.
* GUI seems to be tied to GIF/GS emulation. That research was inspired by Dolphin progress report, and it seems to be correct. Fe/be (frontend/backend) spus are involved here. Which explain some UI slowdowns on GIF intensive games.
* Emulator is full of unused functions. Everything that is compiled inline its also there as separate unreachable function.
* DEV9 registers are not implemented. Reads return 0, writes are void. In simple words Net and PS2 HDD emulation is impossible. Fun fact is that emu perform meaningless check for HDD supported titles.
* USB registers are IMPLEMENTED and seems to be fully functional on ppe and spe side. We are missing something else here, not sure what.
===Registers===
It seems that emulator try to keep lower 64 bits of some r5900 registers in specific ppc registers. At least at the time when recompiler is running, also when 0x01 command run.
This helps little bit with understanding some hooks (0x01 commands). Reason is probably optimization, and cached regs are written only when they need to. At least that how it looks like from analyzing recompiled code.
 
  r0  = 0x200000000, used when recompiler load something directly from EE memory.
r13 = Cycles. When recompiled code run, value is frequently compared to value from negmem F000 and event test is triggered depending on compare result.  
  r14 = r5900_current_pc
  r15 = r5900 pc >> 6, used for cache checks. r15 is also used as temp register when fallback to interpreter, etc.
r16 = r5900_v0_reg_lower64
r17 = r5900_v1_reg_lower64
r18 = r5900_a0_reg_lower64
r19 = r5900_a1_reg_lower64
r20 = r5900_a2_reg_lower64
r21 = r5900_a3_reg_lower64
r31 = r5900_ra_reg_lower64
   
   
  Additionally, Onimusha hooks expect r25 to be r5900 s0, and r28 to be r5900 s3. But i didn't found other parts of recompiler that expect the same. So, for now only values above are confirmed.

=== EE Timers Count Read ===
Emulator have bizarre behavior for EE Tx Count read (0x10000000, 10000800, etc). In specific situation (related to pending edge triggered irq) instead of Count value emulator returns Mode value. This doesn't look like programming error and can be some kind of ps2 undocumented behavior implementation.
 
=== DataStorage vector hook ===
What normally should work as DataStorage exception handler is hacked into very ugly dispatcher for EE related handlers. This code is used for example to read/write IPU registers. At the time when vector is reached:
* Emulator preserves few registers on custom stack at 0x800000. Registers seems to be little random, but they are not. This code is launched from recompiled mips code.
* srr0 is backed up to r3 register (address where exception occurred + 4, rfid opcode jump to address from that reg) and since now it is also used as argument for next steps.
* srr0 is given new value of 0x2EFCC which is custom "dispatcher", link register changes to 0x28F8C8 which is return from that custom piece of... code.
* rfid is hit, let's go to our newly hooked srr0 with 0x2EFCC address.
* Time to use address preserved in r3. This address going thru few checks, it needs to be in 0x10000000- 0x12FFFFFF range (EE JIT Code).
* From this address emulator get single word, that word is used to figure out what mips code wanted to do. This word is ppc instruction that caused exception.
* Code now read extended opcode (XOP) field to figure out instruction type ((code >> 1) & 0x3FF)
* When matching xop identifier is found, task is performed. Some tasks just jump to function and do what is needed, some continue that hackfest and instead are injected into recompiled code as branches to functions that will perform what game want them to do.
* blr is hit, remember that link register is patched earlier to 0x28F8C8
* This function restores previously backed up regs and set link register to value returned by hook. That's all.
 
=== Free sapce in config parser ===
Since CELL B.E. is big endian machine is only natural to Sony to use little endian for CONFIG files and byte reverse every single word for them. :) What's more important for us, CELL have special opcodes for situation like that one, lwbrx and stwbrx (load/store word byte reversed indexed). But compiler decided that it will be better to do old fashioned 8 opcodes load/swap by shifts and masks and 'or'. This leaves us a lot of space when implementing new configs, making things nice and clean without need to jump outside of function, etc. This code:
seg020:000000000012EECC        lwzx      r0, r9, r31
seg020:000000000012EED0        srwi      r11, r0, 24
seg020:000000000012EED4        rlwinm    r9, r0, 8,8,15
seg020:000000000012EED8        slwi      r3, r0, 24
seg020:000000000012EEDC        rlwinm    r0, r0, 24,16,23
seg020:000000000012EEE0        or        r3, r3, r9
seg020:000000000012EEE4        or        r0, r0, r11
seg020:000000000012EEE8        or        r3, r3, r0
seg020:000000000012EEEC        clrldi    r3, r3, 32
Can be replaced by simple:
seg020:000000000012EECC        lwbrx    r3, r9, r31
seg020:000000000012EED0        clrldi    r3, r3, 32
 
== RSX workload on the netemu ==
 
Looks like there is a way to overclock the RSX core by 50 or 100 MHz through LV1 patches. Will the netemu benefit from it?
* Yes, i don't see why not. Assuming that is static patch to elf file, not some cobra style on the fly patch. But don't expect some magic from that. I don't know too much about RSX and not really much about GS. But PS2 emulation is usually limited by CPU power, specially in native resolution. But for example games that need 0x44 cmd, maybe they will work with smoothing now. Maybe some minor slowdowns will be fixed. I still don't know which parts of GS are emulated on RSX, for example softemu used something similar to pcsx2 software render. So there you will get almost nothing from RSX OC. But netemu is different. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 04:56, 20 March 2022 (UTC)
** Tested the 600/750 MHz overclock with a few intensive games (SC3, ToCA3, CMR3, VP2, GT4). Assuming the patches are correctly applied (I have no idea at all), there is no performance boost at all.--[[User:Agrippa|Agrippa]] ([[User talk:Agrippa|talk]]) 15:24, 29 May 2022 (UTC)
*** Little bit late, but it seems that GS is almost fully "software" emulated (PPE + BE SPE). It was mistake to not touch ps2_softemu earlier, because that's what helped me to find out that all shaders in netemu are not strictly emulation related. While softemu have Cg shaders for hardware render. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 14:48, 29 June 2023 (CEST)
 
== Netemu load/store with r0 register ==
 
Emulator access weird addresses which are interpreted as eg. 0xFFFFFFFFFFFF9480, or load/store like std r14, -0x6B80(r0) which translate to std r14, -FFFF9480(r0), and its sign extended by CPU to 64 bit.
Also easier example (without using negative addressing because this is additional emu quirk..). ld r2, 0x3008(r0). This opcode will load double word from 0x3008 address no matter what we currently have in r0, because RA is 0 which is badly interpreted as r0 base.
 
This is because of PowerPC quirk that i (and apparently IDA in 64 bit mode) wasn't aware. From IBM manual:
 
ld RT, Disp(RA)
RT Specifies target general-purpose register where result of operation is stored.
Disp Specifies a 16-bit signed number that is a multiple of 4. The assembler divides this number by 4 when generating the instruction.
RA Specifies source general-purpose register for EA calculation.
 
But according to the same manual:
 
If GPR RA is not 0, the EA is the sum of the contents of GPR RA and Disp. If GPR RA is 0, then the EA is Disp.
 
Tl;dr is that if RA is 0 (which disassemblers show as r0), then Disp is real load/store address. This is used many times in emu itself to access negative addresses (0xFFFFFFFFxxxxxxxx), and is used in all netemu cmd 0x01 hooks.
While this is more PPC itself than emu stuff, i feel is important to mention this here.
Now if we remember that emu have mapped "negative address", loads/stores with r0 starting to make sense.
 
std      r4, 0x3008(r0) # store r4 on 0x3008, no matter what r0 actually is at the moment.
ld        r0, -0x6BF0(r0) # load to r0 from address 0xFFFFFFFFFFFF9410, no matter what r0 actually is at the moment.
ld        r4, 0x3008(r0) # load to r4 from address 0x3008, no matter what r0 actually is at the moment.
 
== Communication with Graphics Synthesizer in ps2_gxemu ==
 
Communication from emu level is done with rw to special addresses of what seems to be RSX ports.
Emu includes thin translation layer that intercept rw operations to GS privilaged registers.
Emulator to write or read GS register first need to write register number that we want to access. To do that we use one of two exposed 32 bit ports, separate for reads and writes.
 
To write GS register first write 64 bit data to write buffer. Separate for lower 32 bit (0xA000304C) and upper (0xA0003048) part of GS write. GS regs are 64 bit while RSX operate on 32 ports.
Finally write translated register number to 0xA0003040. This write starts transfer to GS. To ensure everything went ok emulator performs 32 bit read from 0xA0003000 and check if bit 1 is active.
This operation is performed in loop up to 1000 times until bit 1 is not 0, if that is not the case in mentioned 1000 loops panic is called.
 
To read GS register first write translated register number to 0xA0003050, then wait for bit 1 of 0xA0003000 to be active. Emulator wait up to 1000 read loops if GS didn't answered in that time emu panic.
Now when bit 1 is not 0, data can be read from 0xA0003058 for upper 32 bits and 0xA000305C for lower 32 bits.
Emulator translate almost all reads to CSR. Only SIGLBLID is readable beside CSR. This is real PS2 GS behavior. Although there is unused runtime that allow read any register. Behavior in that case is unknown.

== ps2_gxemu external bios/rom loading. ==
===ps2_netemu===
 
Emulator can load external bios file. File need to be 4 bytes aligned, and 4MB or less size. File name need to be rom.bin (lower case), and probably need to have patched out RDRAM module to success RD check. At least that check is patched in current ps2_gxemu.self rom, maybe is not really needed.
 
To load bios we need to set emulator status flag bit 2 to true. I'm not sure that is already set, because i don't have memory dump, only elf file. In case is not, we can probably just ignore that check by patch. Emulator read file using lv1_read_remote_file with type 1, and path "rom.bin". So it seems to be relative to emulator self file (dev_flash/ps2emu)? All code is there and is valid, so external bios loading is fully implemented. Only two things required to do that is second bit of status flag set to true, and rom.bin file in correct path.
 
Note: This code don't exist in ps2_netemu.
 
== Universal DNAS anti-wipe patch ==
 
Tested with 2.8.0 and 3.0.0 DNAS libraries. EESYNC wipes the memory from 0x00084000 to 0x00100000. Patch is needed for 0x42 command to work with DNAS games when the overlay is installed in this memory region.

== Accurate ADD/SUB ==
=== Cold Fear ===
frequenlty, as if you pressed pause
0x46
0x19


Emulator need accurate math for PS2 floating points operations because PS2 FPU/VU are special (partially also PS3 SPEs, but that's story for different wiki page).
==Obsolete experiments==
PS3 VMX unit in PPU have special compatibility mode with SPU, activated by lv1_set_vmx_graphics_mode(1) hvcall. This is supposed to make floating points operations results as close to SPU as possible. This set default rounding mode to round to zero, denormals are treated as zero, and there are no infinities or NaNs. So practically same mode as PS2 use.
This is kept here for historical purposes, but needs to be rewritten or deleted
Every PS2 EE emulator on PS3 use this mode as otherwise many of that need to be done by software which is inconvenient, and tank performance. There are some suggestions that Sony requested this mode from IBM specifically for PS2 emulators. At this point floats should be handled like on PS2 right? Nope.
PS2 FPU/VU is even more "special" than that, and it seems that Sony missed, or IBM wasn't able to implement that. What is so special? Since PS2 guarantee to round to zero, there is no need for 3 guard bits (more precisely guard/round/sticky bits).
Testing shows that PS2 use only 1 of those bits in way known from other platforms. This makes every FPU/VU ADD/SUB/MUL/DIV operation possibly inaccurate on hardware other than PS2.
There is no way to reproduce that on hardware that is not created with that in mind. No matter it is PS3 VMX, or x86/ARM SSE/AVX. This behavior is not reproductible on currently used hardware without software approach.
But this still doesn't sound that bad, how much developers can rely on bit precise floating point results? 80 from 788 ps2_gxemu configs is using accurate math command, and that's only small chunk of what is really needed. Not to mention direct patches like Persona 4, etc, and tons of custom configs.
<br><br>
Here is function used when accurate ADD/SUB math is requested: https://pastebin.com/sX6vfxin This code run for EVERY SINGLE add/sub separately when opcode is in command range.
<br>
Recompiled code for eg. fpu '''add d,c,b''' looks like this:
vaddfp d,c,b


While recompiled code for accurate fpu '''add d,c,b''' looks like this (simplified):
===Getting Playstation 2 Software Emulator working===
lis a,0xXXXX
ori a,a, 0xXXXX
stvx b,a, 0x0

stvx c,a, 0x0
bla https://pastebin.com/sX6vfxin
lis a,0xXXXX
ori a,a, 0xXXXX
lvx d,a, 0x0


Accurate add/sub is really over-complicated, I think is possible to shrink it to prevents slow downs and cache resets when overused. For example instead of creating "constants", we can really use constants from unused memory. On every single accurate add/sub emulator run this code:
Method (on Firmware 3.55, without! Cobra-USB Dongle or Downgrade) for all consoles (fat & slim).
0x18726C    li        r9, -1                # --- start of "constants" creation ---
0x187270    clrlwi    r9, r9, 1            # r9 = 0x7FFFFFFF
0x187274    stw      r9, 0x20(r31)
0x187278    li        r9, 0xFF
0x18727C    stw      r9, 0x24(r31)
0x187280    li        r9, 31
0x187284    stw      r9, 0x28(r31)
0x187288    li        r9, 23
0x18728C    stw      r9, 0x2C(r31)
0x187290    li        r9, 0x20 # ' '
0x187294    lvxl      v16, r9, r31          # Load from 0x20(r31)
0x187294                                    # [0x7FFFFFFF, 255, 31, 23]
0x187298    li        r9, 0x97
0x18729C    stw      r9, 0x20(r31)
0x1872A0    clrlslwi  r9, r9, 31,23        # 4B800000 ?
0x1872A4    stw      r9, 0x24(r31)
0x1872A8    li        r9, 25
0x1872AC    stw      r9, 0x28(r31)
0x1872B0    li        r9, -1
0x1872B4    clrrwi    r9, r9, 8            # r9 = 0xFFFFFF00
0x1872B8    stw      r9, 0x2C(r31)
0x1872BC    li        r9, 0x20 # ' '
0x1872C0    lvxl      v15, r9, r31          # Load from 0x20(r31)
0x1872C0                                    # [0x97, 0x4B800000, 25, 0xFFFFFF00]
0x1872C0                                    # End of "constants" creation.


All that to load vector v15 with [0x97, 0x4B800000, 25, 0xFFFFFF00], and v16 with [0x7FFFFFFF, 255, 31, 23]. This is really painful when you need to do that on every accurate add/sub, 22 opcodes, even more cycles. But what if we patch emulator to have those values for example at 0x7000 - 0x701F offset? Then loading constants will be:
1. Replace following files on your consoles /dev_flash/
    with the ones included in this archive
    p3dwik-ps2compatfiles.rar
2. Get into Factory Service Mode (FSM Tool/Dongle)
3. Insert your Original PS2 Game Disc
4. It will run.


0x18726C    li        r9, 0x7000
Note: Backups wont work. You're getting the compatibility of the 2.60 software emulator with all of its bugs.
0x187270    lvxl      v16, r9, r0
0x187274    addi      r9, r9, 0x10
0x187278    lvxl      v16, r9, r0


From 22 opcodes we end up with 4. 18 opcodes less on every accurate add/sub. Additionally we can skip preserving/restoring of LR, CTR, and maybe XER. That give another saving of 12 opcodes. Additional 2 opcodes could be saved by not using r6 as temp for save/restore values. We can reuse r9 instead, so there is no need to preserve/restore old r6. All that shrink add/sub from 216 opcodes to 184. For FPU add/sub even more could be done, but for VU/COP2 its most likely only possible optimisation. Still worth it, should bring noticeable difference in framerate on intensive games that need it.

== Ugly fix for HDD whitelisted games loaded through Cobra ==
=== Enable Playstation 2 on non BC's===


The HDD whitelisted games are crashing when loaded through the Cobra (they do work as a 2P package, but the HDD install prompt does not appear of course). I do not know whether the backwards compatible models are affected. The serial ID is compared in the game_ext_plugin module and currently the webMAN MOD does rename the executable inside the ISO to avoid the check. Here is a patch meant to be done on the fly in the payload when mounting the game. Only the SOCOM games have been tested - the HDD install prompt appears and regardless of what you choose, the game will boot successfully.

== Unknown VIF issue - bad cmd ==

Emulator seems to do something wrong when bad (unknown) command is sent to VIF. Since all examples are related to VIF1 lets assume that maybe only that part is broken.


* Buffy send command 0x12 - At the time when command is sent VIF1_ERR.ME1 bit is not set. Correct behavior will be stall VIF, seems to be broken because stall take too long.
==== Service Mode in relation to PS2 emulation tests ====
* Jak TPL accidentally send bad data (vectors floats) as cmd - At the time when command is sent VIF1_ERR.ME1 bit is set. Correct behavior will be ignore bad cmd, and handle it as nop, no stall.
* Service mode resets display settings (on default it uses HDMI with composite on MultiAV connector) - this means that users of Component cables can get garbled screen / no display output (in tests below, the primairy screen) unless using composite wiring/screen (in tests below, the secondairy screen).
* Formula One 05 bad cmd when entering pitstop - Unknown reason, fixed in pcsx2 at some unknown point. Can be dma issue, but worth to check if netemu is affected in any way (https://github.com/PCSX2/pcsx2/issues/2918)
* General note. PS2 VIF seems to be broken by design. Manual have following warnings:
** Due to a failure in determining DMAtag Mismatch error, setting ME0 bit to 0 may generate an error even though a correct packet has been transmitted.  Set the ME0 bit to 1 when using it.
** In V3_16 format, set the ME1 bit to 1.
** The ER0 bit cannot be used appropriately due to a failure in determining DMAtag Mismatch error. Mask the DMAtag Mismatch error detection feature by setting VIF0_ERR.ME0 to 1.


Code which handle bad cmd:
* Service Mode also resets user presets like disc autoboot, so it needs to be disabled again if needed.

*Shoutout to Agrippa for finding where the bad cmd in J&D was sent out.

== Games with EE threading/interrupt issues ==
* Any made Virtual Memory Cards previously will be removed and you will have no access to them, nor be able to create one.


* '''Def Jam: Fight for NY'''
* When PS3 is switching to PS2, connection with Sixaxis / Dualshock 3 will be lost (even when using USB wired connection). In some cases easily resyncable by using PS button, but in other cases the leds stay off and the controller cannot be used (until ps2 mode is exited or console rebooted)
** Random hangs on first loading sequence.
* '''Visual Mix: Ayumi Hamasaki Dome Tour 2001'''
** Random hangs during loading transitions.
* '''Harry Potter and the Chamber of Secrets'''
** Seems to randomly hang on the last stage of loading (ra=0x19bf70). WaitSema calls spotted during the hang.
* '''Gran Turismo 4'''
** Hangs during the FMV playback on the idle wait loop. Game does wait for the interrupt that does not happen, probably.
***Game wait in 81FC0 loop or some custom one? Never leave it? --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 19:01, 11 April 2023 (CEST)
****In the 81FC0 loop. It does leave for a split second indeed, but it is impossible to read the offset. The game is working right in gxemu, I have always wondered if the built-in CDVD emulation may be bugged somehow, introducing new glitches versus gxemu.--[[User:Agrippa|Agrippa]] ([[User talk:Agrippa|talk]]) 19:39, 11 April 2023 (CEST)


Assuming the game programming is right, the underlying issues are data transfer related, probably.
* As a workaround for above wireless controller issue, you can use an USB2PS2 converter and connect an old PS2 / Dualshock2 controller.


== Games with GS emulation issues ==
==== tests on 2000 series PS3 Slim ====
Neither performance, nor mipmap and SCANMSK related.
Testplatform:

** Weapons' trails are rainbow (fixed by Auto-flush in PCSX2).
Firmware: 3.55 'Rogero 3.4' mmap114+peek/poke but no SS-patches
* '''Lord of the Rings: The Return of the King'''

** Top-left corner issue when the mist/fog is rendered.
Mainscreen: Component+Composite 576i+P/720i+P//1080i
* '''Dance Summit 2001: Bust-a-Move'''
Sec.screen: Composite 576i
** Front buffer is not flushed most of the time. Game seems to apply additional effects there, apart from the downsampling.
48 titles tested (PAL disc on PAL SKU) // [[User:Euss|Euss]]
* '''Snowblind Engine 2003+ games'''
** Shows the very last "interlaced" frame when switching back to the interlaced mode from progressive one. I thought it could be a VBLANK issue, but that old frame should be long gone by then. The issue seems to be related to the PCRTC. The SMODE2 register is updated in the VBLANK handler. That old frame is shown when the FFMD bit is switched to 1. Looking for better workarounds than delaying the VSYNC or lowering the resolution in 60 fps mode. By the way, the 0x20 command does work with negative values too. Moreover, the max positive value for NTSC is something like 0x106. Anything higher makes the screen freeze on PS2 logo (but the game is working in the background).

This does not seem to make any stages completable, but it at least helps the AI car in 1-4 get past the indoor section and not get caught up on the turn/area after. Instead, it now hits the orange crate left of the path it is supposed to go. It could potentially have worse effects on other stages as well... Maybe these offsets/functions in particular can help PCSX2 research.

Still same problem of ¨incompatible title¨ and loss of BT/settings. Also after returning to XMB, it no longer sees the disc as PS2 format but as incompatible data (which suggests the lv2 patch is undone, as lv2 is reloaded when returning from the ps2 lpar)
*Try with EU version, you should be able to complete that mission with accu config. I remember that on pcsx2 with hacked vadd almost full EU game is playable. At some point i also hacked dyStepRunge little bit. dyStepRunge1 is less accurate, dyStepRunge5 is most accurate. Game decide which function should be used.

== Patches for SCCS region games ==
* Using [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] without factory service mode : no resetting of date/time/displayoutput (still output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation), and after a long while comes up with the message that the title is not compatible and that the ps3 needs to be updated (Basic nag screen that is on BC PS3s when inserting a noncompatible title).  
Most Chinese region games (SCCS) require the ROM2 modules to be present. However, even if they are required by the game in order to boot, they are not needed at all and are fully playable without ROM2 the vast majority of the time. I have compiled patches for all SCCS games that allow each one to at least boot on PS3 and PCSX2 (older versions, or newer ones without the correct BIOS) by simply skipping over the infinite loops the games get caught in: https://www.mediafire.com/file/skdka574f23b96g/SCCS_patches.zip/file


Mostly untested on PS3, but all have been tested on an older PCSX2 version. PS4 seems to not work with these patches. Even the bootable games without patching needed do not work, so I suspect there is some blacklist preventing them from booting on that emulator. In the end, only two games ended up having text bugs due to the character data not being loaded from ROM2:
* With Factory Service Mode enabled (there are no Xmb options to combinetest with [http://www.ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher] or [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg]): gives ´PS2 disc´ detected at disc icon, but starting gives: resetting of date/time/displayoutput (effectively disabling my mainscreen), then all connection to any bound bluetooth device is lost, even when connected via USB (needs multiple PS button reactivation), and after a long while comes up with the message that the title is not compatible and that the ps3 needs to be updated (Basic nag screen that is on BC PS3s when inserting a noncompatible title).


{| class="wikitable"
In short: [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] and Factory Service Mode seem to enable simulare (it tries to boot it) while [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives you more options e.g. using [http://www.ps3devwiki.com/files/devtools/lv2-v9-pkg/ LV2Patcher].

* I believe that real PS2 also need those patches. For OPL, but not only. ROM2 with CH fonts is not existing outside of 3 ps2 models. All of them released only in China, and one of them is still not even dumped (devkit). This ROM2 is even missing in Hong Kong region PS2. Btw. When i implemented ROM2 support in pcsx2, i tested patching game first. Unluckily for netemu, and fortunately for pcsx2. First and only game i tried to patch was Ape Escape 2. :) --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 12:39, 23 November 2022 (UTC)
** Yup, lucky for me I tested Dynasty Warriors 3 first, then Ape Escape 2 was the second if I recall. I was worried but pleasantly surprised by the rest of the results. I assume ROM2 has data for simplified Chinese characters while Hong Kong/Taiwan uses traditional characters, and that’s probably why there is no ROM2 in the HK/TW region. I am not sure why they even included ROM2 in the first place if barely any games utilize it, but oh well. --[[User:Mrjaredbeta|Mrjaredbeta]] ([[User talk:Mrjaredbeta|talk]]) 18:01, 28 November 2022 (UTC)
*** "PS4 seems to not work with these patches. Even the bootable games without patching needed do not work, so I suspect there is some blacklist preventing them from booting on that emulator.". Just for the record, ps4 don't blacklist them. It's issue with cdvdkey (known for PS3 users as "game hash". ;) ). Emulator fail to respond correctly to one of CDVD register reads. Issue is already patched with my ugly hacks (TC:LA-a-like code swap). Your patches are still required on ps4 after fixing other issues. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 17:39, 20 June 2023 (CEST)


== Removing stuff from ps2 emu page ==


I'm thinking about removing some data from PS2 Emulation page. Mostly stuff that is strictly PS2 thing.
==== Second test: FW 2.70/3.15 ====
Silent Hill : gives disk icon "unsupported data" and error message like "This model of the PS3 system is not compatible with Playstation2 format software" when run via disc icon. Using [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives title not supported error message like "This title is not currently compatible with the PS3 system".


*PS2 Memory and Hardware Mapped Registers Layout
==== Third test: FW 3.55 OtherOS++22GB (with SS Patches) ====
*Video Modes
Silent Hill : gives disk icon "unsupported data" and error message like "This model of the PS3 system is not compatible with Playstation2 format software" when run via disc icon. Using [http://www.ps3devwiki.com/files/OtherOSplusplus/misc/boot_ps2.pkg boot_ps2.pkg] gives blackscreen lockup, not reacting on PS button, or powerbutton, requiring removing powercord.
*<s>Config related info</s> Done.


'''Video Modes''' listed there are not even supported by emulators without GS, and likely to fail even on PS3 with GS. This is really info for PS2 wiki in my opinion. '''PS2 Memory and Hardware Mapped Registers Layout''' also fit more in PS2 wiki. This is more like general PS2 dev knowledge than emulation related stuff. Eventually keep them as a links to ps2tek or ps2 devwiki, or something. Let me know if you think this is/isn't good idea. For example PS1 page don't list stuff like this, same goes for PSP page. In case of Config stuff. This is crucial part of this page, but i feel that harm general readability. Due to complicated nature of PS2 config descriptions are getting bigger, and bigger. Honestly this is still missing a lot of info because many times we are limiting ourself to not make descriptions too extensive. All that to not flood page too much. Maybe it's time to move most of that to new dedicated page? We can leave some basic info, like that small table, plus some '''BOLD''' link to "advanced page". This should allow to wikify and move some non-config stuff from talk page. This are only ideas, i expect not everyone will be happy about all of them. Lets talk. :P --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 08:21, 16 January 2023 (UTC)
* I think these are all good ideas. I occasionally use the PS2 register info for help sometimes, but I could easily use PSI’s page for that (https://psi-rockin.github.io/ps2tek/). I agree that it doesn’t really belong on the page. I agree that emulation page is getting extensive, so maybe it would be good to move the config info to a new page. I am not opposed and are all for it. --[[User:Mrjaredbeta|Mrjaredbeta]] ([[User talk:Mrjaredbeta|talk]]) 15:12, 16 January 2023 (UTC)


== Floating point arithmetic inaccuracies ==
===== considering titles to test =====
* http://en.wikipedia.org/wiki/List_of_PlayStation_3_backward_compatible_PlayStation_2_and_PlayStation_games

While the software emulators are doing a great job with their accurate paths, there are still issues with some games, unfortunately.
These have no listed issues:
* Stuntman/Driv3r
* Half-Life
Completely broken AI, game is unplayable.
* Hulk
* Gran Turismo series
* Medal of Honor: Frontline
An infamous licence demonstration bug - cars deviate from the racing line. It may affect the AI in the race too. Since the GT's AI is retarded, the subject is difficult to confirm.
These have minor issues listed (but should still play):
* Tokyo Xtreme Racer Zero
* Silent Hill 3
It is unconfirmed, but the cars path from PS2 imported replays are played back wrongly in the PCSX2.
* Second Sight
* PRIDE FC: Fighting Championships
It seems that y × 1 ≠ y sometimes. Fixed by patching the game code.


== Manipulating r5900 cyclerate ==
==== tests on CECHC04 (partial BC) ====
on 3.41 or on 3.55 in normal XMB mode (no disc icon in XMB): boot_ps2.pkg gives no resetting of date/time/displayoutput (still output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation), and after a long while comes up with the message that the "The system was not turned off properly" as if it had experienced poweroff and from there booted back to XMB. It then returns to the XMB, but first gives an error screen, mentioning 0x80028F17 occured (''PS2 mode error 0x80028F17 "An error occurred during the start operation (80028F17)," PlayStation 2 disc Boot Error, also related to PS1 PSN games.'')


Cycles are count in function located at 0x17C9D0 (latest netemu). Emitter with addi to r13 register is what we are looking for. Since pcsx2 use different "unit", lets just call cycles here a... unit.
on 3.41 or on 3.55 in normal XMB mode (disc icon in XMB): boot_ps2.pkg gives resetting of date/time/displayoutput (no output on mainscreen), but all connection to any bound bluetooth device is lost, even when connected via USB (need PS button reactivation). The game is playable on secondary screen, and exit to XMB with holding PS button goes without 0x80028F17 errors, but does give the "The system was not turned off properly" error.


  _________________________________________________
no disc icon:
|  Opcode type  |  Netemu/Gxemu  |    PCSX2  |
* Medal of Honor: Rising Sun
|----------------|------------------|-------------|
* Half-Life
| Default opcode |    1 unit      |    9 units  |
| Load/Store    |    2 units      |  14 units  |
| Multiply      |    4 units      |  16 units  |
| Divide        |    37 units      |  112 units  |
| COP 0          |    1 unit      |    7 units  |
| COP 1          |  1 unit(some 2)  |    7 units  |
| COP 2          |    1 unit      |    7 units  |
| NOP            |  0 units(!!!)  |  7? units  |
---------------------------------------------------
Additionally pcsx2 use different cycles for many other opcodes that ps3 emus just count as one.
  * MMI      =  14 units
  * MMI Mult =  24 units
  * MMI Div  = 176 units
  * FPU Mul  =  32 units
At the second hand gx/net emu do some weird shenigans with cycles based on... Opcode number, this is still small unknown here. Yeah...
  It turns out that emu is not counting nop cycles. Weird shenigans mentioned above check if opcode number is 1, which belongs to ee NOP in internal emu table.
  When opcode is NOP then emulator is not adding even single cycle. This explains a lot of issues with dma and why EE always seemed too fast for DMA and other components.
  This code takes 2 cycles (units) per loop in emu:
loop_here:
  addiu v0, -1
  nop
  nop
  nop
  nop
  nop
  bnez v0, loop_here


I still need to fully confirm that nop isn't handled in some special way elsewhere but looks like it's not.
disc icon:
* Hulk
Underclocking/Overclocking could be done by modifying opcodes at 0x17CEB0, 0x17CFF8, 0x17D4C8.
* Second Sight
What has been tested do far is shifting by 1 or 2 to the left (underclock by multiplying passed cycles). Sadly without any possitive result to framerate, shift by 2 was even slower.
* Silent Hill 3


== Emulator status flags ==


We can't really modify this flag from outside on retail emu, but we can always patch function that do init.
===Netemu===
Localised at 0x934158 of emu memory.
1        = init done?
2        = unk thr sys
4        = unk thr sys
8        = unk
10      = run watchpoint opcode (debug halt) 0x11DD80
20      = set mecha 0x245828A to 2, and run sc8 (0x200)
40      = some setting for spe0_class0_int_handler
80      = enable cmd 0xF/0x26/0x27 for whole memory range
200      = set when emulated hardware init is done
400      = enable 0x934160 debug flag (watchpoint on ee and on iop)
800      = skip parsing config file
1000    = do cmd 0x1F with 0x3E8(1000) param
4000    = enable cmd 0x11 for whole VU0 mem (per range setting is inaccessible from config!)
20000    = skip SCED discs error (more, todo)
40000    = do cmd 0x14
80000    = memory card related (0x12A6D8) also run sc_7(2) in thr hdd
200000  = do cmd 0x05
400000  = enable config cmd 0x10 for whole memory range
800000  = do cmd 0x12 with 0x2DFF000 flags
4000000  = mecha related (todo 0x135664)
8000000  = run loop that wait for 0xB52BB8 to be non zero
10000000 = watchpoint (if thread flag is set)
20000000 = timing setting for media validity check
80000000 = show health warning message
Need work


===Gxemu===
==== PS2 on non BC HW - Tests ====
Localised at 0x3ED0 of emu memory.
1        = init done?
2        = load external bios.rom
4        = run sub_56784 and sub_56A6C
8        = unk
10      = run watchpoint opcode (debug halt) 0x3F02C
20      = set mecha 0x177AA4F to 2, and run sc8 (0x200) ___todo
40      = some setting for spe0_class0_int_handler
80      = enable gx cmd 0xC/0x22/0x23 for whole memory range
200      = check byte 0x6E6302 and do something if 2. Seems to disable media validity test. Set after EE hw init.
400      = set 0x3D60 to 1
800      = skip parsing internal config list
1000    = do gx cmd 0x1C with param 0x3E8 (1000)
4000    = enable cmd 0x0F for whole VU0 mem (per range setting is inaccessible from config!)
10000    = used as a param for sub_40054, unknown. Not available in netemu
20000    = skip auto setting gx cmd 0x19 for games from hashlist, and later in different sub. Also skip setting SCED error.
40000    = do gx cmd 0x12
80000    = skip running unk syscall
100000  = do gx cmd 0x19 (command unavailable in netemu? Looks different)
200000  = do gx cmd 0x04
400000  = enable gx cmd 0x0E for whole memory range
800000  = run sub sub_F1D78, seems to be much more complicated version of what netemu do here.
1000000  = set 0x3D63 to 1
Need even more work...


== Memory Map ==
{| class="wikitable sortable"
=== Netemu ===
Tables at main page taken directly from emulator memory seems to be wrong. I double checked this and values are really there, but ea just don't match to what emulator code do (lpars are most likely correct there). So here it is memory map with addresses that emulator use when want to reach any of mentioned regions.

== Negmem ==
-- Moose


Netemu use memory part called internally negmem. Memory is mapped to 0xFFFFFFFFFFFF0000, but emulator take advantage only of memory from 0xFFFFFFFFFFFF8000 to 0xFFFFFFFFFFFFFFFF. Why? Because that range is loadable with single opcode. How? By "r0" loads/stores (https://www.psdevwiki.com/ps3/Talk:PS2_Emulation#Netemu_load.2Fstore_with_r0_register). With that clever way emulator can access high addresses by setting negative offset for r0 register. This range is used for PS2 registers, DMAC status, next event delta, INTC, and many more. That way emu is able to load value from cached ps2 register in single opcode! Very clever idea!

== Custom command ideas ==
 
* '''Disable GS downloads.'''<br>
It is definitely a performance improvement for many titles. In theory, easy to implement (force 0x3 TRXDIR value for every 0x1 write instead). The point is, per-game patches are superior and more robust.<br>
* '''Disable PCRTC blur.'''<br>
PCRTC merge circuits are mostly used for pathetic blurry anti-aliasing. Looks awful on modern TV screens (ToCA 3 is unreadable completely). Blending settings are controlled through the PMODE privileged register. Partially implemented here: [[Talk:PS2_Emulation#Remove_PCRTC_Blur_for_Netemu|Link]]
 
 
===Discussion===
GS download config is partially done, need little bit more than TRXDIR patch. But this is something we can patch per-game too. Games do very obvious things to reverse VIF1 FIFO, and also BUSDIR write. From there you can disable whole function that need it. Config will be better of course, but HEN users... Anti Blur is kinda easy to do. Writes to DISPLAY1 can write also to 2 and write to 2 also to 1. So they always match, and config implementation will be rather easy. Most games just offset DX/DY, and never touch those regs again. For games that mess with it, more serious approach is needed. But again HEN users are out of luck if we create command for that. It doesn't help that this can be done by EE patches too. What need to be done is removing offset between DISPLAY1 and DISPLAY2.
*Example for TOCA3 SLUS which use hard coded offset:
004C55F0 00000000
004C55F4 00000000
I'm not saying no, but for now i'm kinda lacking of motivation if not so small HEN user base will be out of luck. But more ideas can help with motivation. :P --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 22:00, 8 August 2023 (CEST)
 
== IOP Handling in ps2_emu? (CECHA/CECHB) ==
 
So, I was reading about how the emulation works here, but I'm not sure how the hardware-based emulation works in the IOP part.
 
The chart clearly shows that IOP is being 100% emulated via software (Cell) on ps2_gxemu and ps2_netemu, but what about ps2_emu? Is it being emulated using hardware like the EE and GS? Or is it software? I couldn't find any physical chip leading to believe the hardware IOP is there (although the PS2 Bridge has a very similar number model), but I'm aware that some games which have IOP issues on ps2_gxemu and ps2_netemu are not affected in ps2_emu. Also some games that could go online were working fine on ps2_emu, but not so in ps2_gxemu and ps2_netemu.
 
Is the IOP really fully emulated via software in CECHA/CECHB consoles?


* It's emulated. While other emus use new IOP emulator that is fully running on SPE, ps2_emu use IOP emulator running mostly on PPE core. Emulated IOP ram is mapped to 0x100000000 address of emulator memory, and it's accessible by whole emu. Interpreter is quite simple but handle all needed stuff. IOP hardware registers are mapped in emulator memory and read/write handlers are all PPE functions (that includes DEV9, USB, etc.). IOP Timers run on one of SPE cores, which is interesting solution. SPU2 is running on separate SPE core too. IOP side of SIF communication is done thru "SIF" named SPE program, this program is communicating directly with CXD9208GP hardware. This includes 0x1D0000XX, SIF DMAs, etc. That part is generally not part of IOP per se, I'm just mentioning it for clarity. About compatibility. IOP emus in other PS2 emulators on PS3 were rewritten from scratch, i guess that's why they are less accurate. Plus, fact that with real EE Sony was able to drive most timings inside emu by EE vblk/hblk, which simplifies emulated communication. There is not much to do with accurate IOP when your emulated EE timings are off. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 20:19, 24 September 2024 (CEST)
==Game compatibility lists==
There was some game compatibility tables here that was intended as a layout with lot of game names but no info about them that was never used


* Thank you very much. all of that is pretty informative and fully answers my questions. The last one I have, does this means then that the software emulation that ps2_emu is doing to the IOP part is more accurate than the one DECKARD does on Slims PS2 right? I tried games like Beyond Good & Evil and it seems to run well without the sounds issues that game has on slims models.
The info has been moved to: [[Talk:PS2 Emulation/Old PS2 Game Compatibility Lists]]
** Yeah, looks like it is. Possibly that wasn't the case back in the release days. PS2 emu has been updated many times since launch in 2006, who knows why... You may want to check this compatibility list: https://en.everybodywiki.com/List_of_PlayStation_2_games_compatible_with_PlayStation_3 It's not that accurate because for example Persona 4 entry is partially bullshit because issue with the bar in the lower left-hand corner just can't exist on real EE. But generally, it will give you some info what doesn't worked back then. Entries like Battle Stadium D.O.N, Naruto Shippuden: Ultimate Ninja 5, Orphen: Scion of Sorcery, Wild Arms 5 or Ibara are really interesting, but I'm not sure if they are correct. Back then people recognized PS3 model by HDD size, You can imagine that it's not most accurate way to do that. :D --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 08:32, 25 September 2024 (CEST)
***Of course, the HDD size is not the reliable way to identify models, especially when you can just swap the HDD haha. Thanks, you gave me a lot of interesting info, checking the compatibility list I saw a lot of interesting cases, perhaps if one day I'm bored enough I will try the examples of games you gave me, and also try some others. Would be fun if ps2_gxemu could be run on CECHA/B models, I'm aware its not possible, at least not right now (I also tried by swapping them in dev_blind with no success, just a black screen crash, but since it's looking for different hardware on the motherboard this was kind of the expected behavior).
In the end, I guess that games like Ratchet & Clank or Tekken Tag Tournament which runs really slow on ps2_gxemu is because Cell can't keep up with the EE emulation.
