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

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

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

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

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).

|-
| 0 || IOP || 0x40000000 - 0x4003FFFF ||  0x0 - 3FFFF

Additionally, emulator access SPU directly with those addresses. <br>
{| class="wikitable"
|-
! Address !! Channel !! Channel description !! Access type !! Notes
|-
| 0x44004 || SPU_Out_Mbox || SPU Outbound Mailbox Register || Read only || Used to read 32 bits of data from the corresponding SPU outbound mailbox queue. Outbound Mailbox Register has a corresponding SPU Write Outbound Mailbox Channel for writing data into outbound mailbox queue.
|-
| 0x4400C || SPU_In_Mbox || SPU Inbound Mailbox Register || Write only || Used to write 32 bits of data into the corresponding SPU inbound mailbox queue. Inbound mailbox queue has a corresponding SPU Read Inbound Mailbox Channel for reading data from the queue.
|-
| 0x44014 || SPU_Mbox_Stat || SPU Mailbox Status Register || Read only || Contains the current In_Mbox/Out_Mbox/Out_Intr_Mbox count of the mailbox queues in the corresponding SPE. 
|-
| 0x4401C || SPU_RunCntl || SPU Run Control Register || Read/Write || Used to start and stop the execution of instructions in the SPU.
The SPU can dynamically change the state of the Run Status bit (that is, SPU_Status[R]). 
|-
| 0x44024 || SPU_Status || SPU Status Register || Read only || Used to report the status (state) of an SPU. Emulator use it mostly to check if SPU is running (bit31).
|-
| 0x44034 || SPU_NPC || SPU Next Program Counter Register || Read/Write || Contains the address from which an SPU starts executing when the Run Control bit is set in the SPU Run Control Register.
Used in function that start SPU programs, and in interrupts handlers, plus in few other places.
|-
| 0x5400C || SPU_Sig_Notify_1 || SPU Signal Notification 1 Register || Read/Write || Used to write data that can be read in SPU_RdSigNotify1 channel corresponding SPE.
|-
| 0x5C00C || SPU_Sig_Notify_2 || SPU Signal Notification 2 Register || Read/Write || Used to write data that can be read in SPU_RdSigNotify2 channel corresponding SPE.
|-
|}
Address = SPU base + Address. For example, IPU SPU is mapped to 0x40300000 so accessing SPU_Sig_Notify1 will be done by read/write to 0x4035400C.

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.

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

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

So by PS2 memory mapping is ((offset + 0x11000000) & 0x11000FF8)<br>
Function is somehow related to all Upper pipeline ADD/SUB operations (incl. opcodes like MADD, OPMSUB, etc.).<br>
When offset is hit, opcode is processed using different code path, probably more accurate.<br>
Note: Due to how VU work, exact offset in VU memory will be param + 4, because VU process 2 opcodes in same time.<br>
Lower pipeline fetch opcode from address, Upper from address + 4.

  Config run the same function which is run when PS2 syscall 7 (ExecPS2) hook is triggered (0x1831A8 in latest emu memory).

Only difference is that 0x42 overlay is not reloaded, and check for "cdrom0" string is not performed.

Command could be potentially useful for games that like to change own code. Eg. Load "bin" files with code (HSG/HST), or modify own code by direct writes to memory (NFS Carbon CE...)

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).

Command present only in the ps2_netemu. Maximum List Count: 32. Mode is first 4 bits of address field (Xyyyyyyy), can be either 0, 1, or 2. All known examples use this command in 0 mode, and modes 1 and 2 are here just for documentation purposes.
| 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.
*mode 0 - Replace 32 bit of EE memory. Params are EE offset, original opcode, replace opcode.
  Count is size of patch in 4 bytes opcodes. So 5 opcode patch = count 5.
*mode 1 - Write jr ra, li v0, xxxx to selected memory range. Params are EE memory start address, original opcode, u16 counter, u16 value for li, v0 xxxx
  Opcodes will be placed on selected address, we use only patch code, no need for original opcode.
*mode 2 - NOP memory at selected range. Params: start address, end address, unused (can be anything, but is required to align config).
  Next opcode addresses are auto calculated (+4..) so we need to specify only patch start address.
Problem: Original opcode validity check is performed before testing config for special cases. Thus making mode 2 almost inaccessible.<br>
  Remember we need to jump to our new code, best way is command 0x0A with j (jump) opcode.
Solution: We can patch that one line of code by the same 0x0A config. So if we want to nop region from 0x100000 to 0x100080, first we need to patch 0x100000 to 0x100080 opcode. So check will pass, "simple" as that.
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=0x11|name=VU0 Accurate ADD/SUB|data=1x uint32_t Param}}
Param is VU0 (MICROPROGRAM) memory offset, correct param is in range of 0x000 to 0xFF8.
Lower pipeline fetch opcode from address, Upper from address + 4. So correct address for config needs to be 8 bytes aligned.

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.
  Allow  display_mode 1 (CELL_GCM_DISPLAY_480_unk2) (59Hz?) [640x480]
  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.  
and     display_mode 5 (CELL_GCM_DISPLAY_720P_59)         [1280x720]
  Later bits are dependent on which subcommand we want to run.
depending on sys_info.video_mode & 0x200 is 0 or not.
 
  Both 480 modes can be either I or P, so is something else, probably 59/60Hz.

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.

====Inside ps2_gxemu.self/ps2_softemu.self====
Command not available in ps2_netemu.self
There are hundreds of configs hidden in ps2_gxemu, and ps2_softemu self files. Internal config structure is basing on custom hash based on Title ID, internal memory offset pointing to place where true patch instruction is, and count of used commands. When disc/iso is started emulator search for configs, and if config for selected ID exist, then emulator apply it by itself. Is not perfect way of applying patches, because some games use the same ID, but different content. Good example here is Star Wars Battlefront II SLUS-21240, where some versions of game can refuse to work because it apply bad patch.

==TitleID/DiscID in ps2_netemu.self==
Similar to 0x0D with param 0. Affect the same IOP related code path, but skips more code.  
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.

Change VIF1 command 14h MSCAL behavior to use 15h MSCALF (VIF1) instead. MSCALF behavior is the same as MSCAL, but also waits for PATH1 and PATH2 to not be active before starting a microprogram. This is hack, and MSCAL should be fixed instead to wait in queue instead of triggering early.
Applies to the Snowblind Engine games. Fixes the rest of flickering textures.
Meant to be used in conjunction with the GX/SOFT Snowblind Engine's specific commands (double 0x01 and 0x23 combo).
 
{{Boxcomm|id=0x4B|name=Redirect SAVEDATA by ID|data=2x uint32_t + ID: offset, int, char[]}}
For proper config we need at least 2 (can be more if needed) 0x4B commands, one to enable redirect, one to disable.
First param is EE memory offset that when is hit enable/disable redirection.
Second param is used to select which card will be redirected:
  0x00 do nothing
  0x01 for SCEVMC0.VME
  0x02 for SCEVMC1.VME
  0x03 for SCEVMC0.VME and SCEVMC1.VME
  0xFFFFFFFF to disable redirection, and use original VMEs.
Third param is ID of SAVEDATA we want to use padded with 00 to match 12 bytes, or all 00 in disable redirect config.
Important note here is that config have own 00 00 00 00 terminator at the end.
So after 12 bytes of ID we need to add 4 bytes of 00. That apply also to disable redirect version.
Under the hood config also setup 0x01 hook commands with 0x39 subcommand on selected addresses.
 
{{Boxcomm|id=0x4C|name=Unknown|data=2x uint32_t + ID: offset, int, char[]}}
Used to redirect to different ISO without game reset. First param is EE offset to hook, second param is some kind of mode selector, depending on that
emulator later set mecha switch disc state:
  mode 0x01 = set disc switch state to 1 (on next mecha main loop it will emulate opening the tray).
  mode 0x02 = set disc switch state to 3.
  mode 0x03 = set disc switch state to 3. This state repeats because it work different way depending that emulated tray is closed or no.
  mode 0x04 = set disc switch state to 2.
  mode anything else = do nothing.
Third value is ID in big endian hex ascii (eg. NPJD12345), additionally 0x4C expect own 00 00 00 00 terminator. To eventually end redirection use
another 0x4C but with (offset, 0xFFFFFFFF, 4 * 0x00000000 . This config have very similar usage to 0x4B, just redirect to different iso, instead to
different MC. Currently is unknown that cobra patched emulators support that config properly, and swap disc thru 0x00 command seems to be easier.
This config don't work if 0x00 multidisc config is detected. Config under the hood setup 0x01 hooks with subcommand 0x3A
 
{{Boxcomm|id=0x4D|name=Unknown|data=1x uint32_t}}
Param is floating point value. Default value 0.
if Q in GS RGBAQ write is 0.0 or -0.0 then
    Q = Q | value from config
else

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

|-
| Missing Emotion Engine Data Cache emulation || Emulating that is literally not possible without making games run at 3 fps. Fixed by patches to game image, or EE code. Instruction Cache (not Data) seems to be implemented, at least partially. || Ice Age 2, DOA2: Extreme, Nascar 2009.

| Unmapped write only EE memory (confirmed only for SIF) || Reads/Writes to 0x2000000+ shouldn't throw bus error on dma transfers. Write should be performed as successful, memory should stay unchanged. Reads should return 0. || Games developed by In Utero, while creating initial save file, send DMA where address is EE stack pointer. At the time of transfer start $sp is too high, and requested transfer size make MADR overflow above 0x2000000 at some point. This is game bug, and happen also on real hardware. Fixed by config.

| VU0 is not running in sync with EE core || VU0 is running program "at once", which mean that VU0 run until it hits E bit. From EE perspective it looks like whole VU0 program run in 1 cycle. Games that expect VU0 registers to be changed from EE side while VU0 is running are broken due to that. Partially resolved using 0x12 command with 2/3 subcommands, or by code rearranging.|| 24 The Game, ATV Quad Power Racing 2, Twisted Metal Head-On, Primal, Ghosthunter, Rayman Arena, Rayman 3, Largo winch.

| M-Bit not supported || Emulator ignore VU0 M-Bit, that cause issues for games that need it to work correctly. This is done because there is no way to sync correctly running VU0 without sync with EE. Partially resolved on emu using 0x12 command with 2/3 subcommands, or direct VU0/MIPS code rearranging. || Totally Spies!

|-
| T-Bit not supported on VU0 || Emulator ignore VU0 T-Bit, that cause issues for games that need it to work. Note: T-Bit is correctly handled for VU1. || Spiderman 3 set T-Bit, then do cfc2 from TPC (address where VU0 stopped). Since T-Bit is ignored, TPC is wrong. Value is later copied to CMSAR0, and program continue at wrong address. Well that's what should happen, but T-Bit also not signalize correct bit in VPU-STAT.

|-
| Emulator do not update correct flag instances for COP2 while ending VU0 program on Ebit || This cause few games to read bad flag status (not status flag!) on COP2. This is resolved on emu by forcing update of MAC flag on every STATUS flag read (by config 0x12), this cause slowdowns creating a lot of unnecessary operations. || Driving Emotion Type-S, State of Emergency 2, The Getaway Black Monday.

|-
| In corner cases emu select wrong block flags pipeline state (both VU0/EEonBE and VU1/VRC affected). || This can cause various issues, mostly SPS, missing graphic, specific slowdowns, etc. Issue seems to occur when branch/jump delay slot have opcode important for flags calculation. Theory is that cached microprogram don't include modified flags state from delay slot instruction. So when already recompiled program is fetched from pool, it will miss one cycle in fmac flags pipeline. This can be crucial in games that rely on it. || Tales of Legendia and Klonoa 2 set sticky flag bits to 0 and branch with sub.xyzw in delay slot (expecting that sub change status flag), Tamsoft engine games set sticky bits to 0 in branch delay slot, this was most ridiculous bug, because problematic branch was pointing to next opcode after delay slot, removing branch was enough. True Crime: NY is only known game where VU0 is affected by this bug. more..

| CTC2 opcode write whole value to R register, while only 23 bits are writable. Rest is hardcoded to 0x3F800000. || Can cause many weird issues like broken physics, broken graphics.

| CFC2 from R register should return only 23 lower bits. || CFC2 from R on real PS2 return only lower 23 bits. Originally found out by PCSX2 team  [[https://github.com/PCSX2/pcsx2/pull/8409 more]] and later confirmed to affect ps2_netemu in emu assembly. || There is only one game that is known to be affected, Onimusha Dawn of Dreams.

|-
|-
| Missing floating point result overflow/underflow detection (U/O flags not set) || Since this affect all units (FPU/VU), many issues can occur. But in reality it seems to not affect any games. While this is easier to implement than on x86 system (full floats range, compared to ieee754), there is no way to do that by hardware way. Because SPU add/sub don't set those flags on single precision operations, and vmx have them disabled in spu compatibility mode. || Superman Returns.

|-
| DMA between SPR and VU1 memory cause emulator panic. || Currently cause is unknown. It seems that functions responsible for transfer don't check that VU is running. Manual state that dma can be performed only when VU is not active, and pcsx2 wait until VU end. Games affected in emulators on ps3 display this warning in pcsx2 if mtvu is enabled: "MTVU: SPR Accessing VU1 Memory". Affected games are fixed by rearranging code to do lq/sq loop instead of DMA. || Summoner 2 (SPRfrom to VU1 data mem), Kaena (SPRto from VU1 data mem).

| IOP SIF0/1 DMA IRQs can be disabled (masked), which is not true on real hardware. || IOP interrupts 0x2A and 0x2B should always trigger. Fixed by patches to IOP code. Ps2_emu seems to be unfacted, probably handled on real hw in CXD9208GP. || Knockout Kings 2001, DOA2: Hardcore.

|-
| 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.

==TitleID/DiscID in ps2_netemu.self==
There are 193 titleIDs listed inside ps2_netemu.self. More precisely, into XPARAM2.ELF file of PS2 Bios included in ps2_netemu.self. XPARAM2.ELF is called by OSDSYS, then ID check is performed. If title ID match to one of included in the table, different IOP emulation settings are applied.
There are internal flags related to every title ID included inside file, still unknown what they do. Also some arguments, in plain text. File in real ps2 is introduced in SCPH-750XX models so exactly when DECKARD Power PC chip exchanged original IOP chip. This can explain why it is still in PS3 netemu bios. Because PS3 it is ppc that can need the same/similar flags.
 
Original PS2 bios include similar list file called XPARAM.ELF, but Title IDs there are not the same, although some of them exist on both lists.

==Other game patches (unofficial)==
|-
There are other unofficial ways to patch the PS2 games such the [https://forums.pcsx2.net/Thread-A-simplistic-guide-to-pnach-files-aka-pnach-for-dummies pnach] format, or the widescreen patches that allows 16:9 screen output for some games by hex editing the ISO, or by applying ppf patches. Games work fine on PS3 with same compatibility like before patching. Also some 480p (aka progressive scan) patches work fine. http://ps2wide.net/

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

==Other game patches (unofficial)==
There are other unofficial ways to patch the PS2 games such the [https://forums.pcsx2.net/Thread-A-simplistic-guide-to-pnach-files-aka-pnach-for-dummies pnach] format, or the widescreen patches that allows 16:9 screen output for some games by hex editing the ISO, or by applying ppf patches. Games work fine on PS3 with same compatibility like before patching. Also some 480p (aka progressive scan) patches work fine. http://ps2wide.net/
 
The problem of this methods is the patch is applyed over the ISO and is modifyed permanently, but this problem can be avoided in PS3 because that unofficial patches can be "ported" to the official config format to be used by ps2_netemu.self, by using the official config format the settings and patchs from the config file are applyed "on the fly" and the ISO is not modifyed


==ps2_title_brute code==
A script to calculate whatever this encode is that is used in ps2emu, gxemu and softemu from given input title id.


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