Description[edit]

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 literally what PS2 VU was originally. Although SPE, and PPE SPE compatibility mode can still be inaccurate comparing to PS2. Good example here are TriAce games, or Castlevania COD where SPE calculation is wrong by 1 bit making games unplayable without patch. This is due to some 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)[edit]

  • 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.

BIOS[edit]

ps2_netemu.self[edit]

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 is to be Developement v2.20 from Japan region (22/01/2007), but it's of course not limited to booting only NTSC-J games.

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[edit]

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.

  • and the usual either replace read/ioctl for iso etc.

Game CONFIG[edit]

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)

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

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

Config Commands[edit]

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.

0x42 EE Overlay patch. 2 main Params + patch data: uint32_t address, uint32_t count, opcode,opcode,opcode...
Address need to be in 0xFF000 - 0xFFFFC range.
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 1 Param --- Equal to 0x40, but with Parameter:
0 = Default
1 = (like 0x40)

  • 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

0x49 0 Param --- Sets something 0xB,0,0
0x4A 0 Param --- Sets something 0x15100
0x4B Redirect SAVEDATA by ID, 2 x uint32_t Params + ID: offset, int, char[12]
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.
0x4C 2x uint32_t Params: offset,int (2 = current path?, 3 = new ISO.BIN.ENC path?, other= ?)
0x4D 1 uint32_t Param (can be -1) --- Sets something (same as 0x49 but) 0xC, Param, 0
0x4E (nothing)
0x4F (nothing)
0x50 0 Param --- Enables pressure sensitive controls

Inside ps2_gxemu.self/ps2_softemu.self[edit]

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[edit]

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 Cache emulation Emulating that is literally not possible without making games run at 3 fps. Fixed by patches to game image, or EE code. Ice Age 2, DOA2: Extreme, Nascar 2009 (luckily fixed by instant VIF bug).
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.
VIF is instant There is no correct timing, or even attempt to emulate that. Everyting done by VIF0/1 is done right when pushed Nascar 2009 is affected in possitive way, game don't have time to corrupt transfer. Probably many more games.
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 Seems like old pcsx2 mVU approach is used where VU0 is running thousands of cycles ahead of EE. Partially resolved on emu using 0x12 command with 2/3 subcommands. 24 The Game, ATV Quad Power Racing 2, Twisted Metal Head-On, Primal, Ghosthunter, Rayman Arena, Rayman 3, 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. Totally Spies, 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.
Emulator Fail to save correct flag instances 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 unnesessary 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 pipeline state while processing Flag VU opcodes. This can cause various issues, mostly SPS, missing graphic, specific slowdowns, etc. For now it was only confirmed that FSAND opcode don't ask for exact pipeline state, but looking at assembly of other opcode this rather affect all of them. Tales of Legendia, more..

TitleID/DiscID in ps2_netemu.self[edit]

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)[edit]

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[edit]

A script to calculate whatever this encode is that is used in ps2emu, gxemu and softemu from given input title id.

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"
