The fact of the matter is that the PS4 is too weak for emulation, For that reason alone, Sony had to sacrifice accuracy in order to gain Performance,

But the Ps4's emu has more accuracy than PCSX2 in terms of GS and SPU Emulation, As for the other parts, PCSX2 is much better at emulating it, For instance PCSX2 syncs VU0 extremely well, the Ps4 doesn't, And it's because it doesn't have the horsepower to do that, And that has to lead to games like Rayman 3 being unplayable without overclocking the EE at a specific offset.</pre>

<pre>Each PS2 game PS4 package file (.pkg) includes the emulator itself, there is no included emulator in the PS4 firmware. although The PS4 firmware has some PS2 emulator specific features, like the functions sceLncUtilIsPs2Emu, sceShellCoreUtilGetImposeMenuFlagForPs2Emu, sceSystemServiceAddLocalProcessForPs2Emu, or sceSystemServiceShowImposeMenuForPs2Emu.
These PS2onPS4 games can be bought online directly via Limited Run Games for brand new or for example on Ebay for second hand or like new.

Emulators are programmed to be accurate for the games that they were extracted from, and that alone provides a challenge For accurate Emulation. since emulators include per title patches, and different default settings, and since the Playstation 2 hardware is known to be one of the most complex systems to emulate, any small change in configuration can have negative consequences in Games.

= Description =


Currently the most used emulator is Jakv2 since it is the most compatible, but for game crashes we use RECVX, and for VU accuracy we use roguev1.
The PlayStation 2 emulation on the PlayStation 4 is handled with little difference to the PlayStation 3. Some issues on PS3's PS2 emulator were left unfixed on the PlayStation 4. Consequently, the PS4 inherited some of PS3's emulation glitches, and even introduced new ones. The new issues came as a result of PS4's weakness with emulation, which likely resulted in the trade of accuracy for performance.


Also note that the BIOS itself is included in the game's pkg and it is the exact same BIOS that was used in the ps2_netemu. Another important thing is the lack of encryption mechanism for PS2 game disc image file, this time it is just a plain ISO file, but the emulator still supports LIMG sector that allows the usage of non-2048 sector size discs. Memory card is also decrypted, but the emulator checks the crc of some of the regions to ensure that the memory card was Not modified. the PS2 Emulator supports LUA scripting by "Lua Bridge", and it is an extremely powerful interface that provide many possibilities to improve compatibility.
Each PS2onPS4 package file (.pkg) includes the PS2 emulator itself. The PS4 does not have a native built-in emulator in its System Software, but it does have a few PS2 emulator specific features, like the usermode functions sceLncUtilIsPs2Emu, sceShellCoreUtilGetImposeMenuFlagForPs2Emu, sceSystemServiceAddLocalProcessForPs2Emu, and sceSystemServiceShowImposeMenuForPs2Emu.


This is first time that sony really cared about floats in their emulator. Compared to the PS3 CPU, x86-64 is doing a worse job in mimicing PS2 FPU, and VU floats calculation behavior. This is resolved by clamping, accurate math used per memory offset, and/or converting floats to double precision. the emulator uses openCL for GS, and probably other components.</pre>
The PS2 emulators are programmed to be accurate for the games they were designed to emulate. In turn, this makes accurate emulation challenging, as emulators include per-title patches and different default settings. The PlayStation 2 hardware is a complex system to emulate; any small change in configuration can make or break a game. Currently, the most commonly used emulator is "Jakv2" from Jak games, as it is the most compatible one out there. When game crashes are concerned in an emulated PS2 game, then the Resident Evil Code: Veronica X's emulator is typically used, whereas for VU accuracy it is Rogue Galaxy's.


The PS2 BIOS is included in the game's pkg file. It is the same PS2 BIOS as used in the ps2_netemu in PS3 Operating System. The lack of encryption mechanism for PS2 game disc image files is also huge. This time, it is a plain ISO file, but the emulator still supports LIMG sector that allows the usage of non-2048 sector size discs. Moreover, memory cards are also unencrypted, but the emulator checks the CRC of some of the regions to ensure that the memory card was not modified. The PS2 emulator on PS4 also supports LUA scripting by a "Lua Bridge", which is a powerful interface that may prove exceptionally handy in fixing games.

Emulator configuration is handled by 4 files:

<pre>The FPU is a fast single-precision unit that typically serves the EE by calculating in-game physics. It mostly controls the accuracy of the movement of in-game objects, or the game's gravity as a whole.

$ goes to the specified succeeding offsets. $0 will go 2 bytes forward and changes them. $1 will go 4 bytes forward and changes the 2 bytes specified. For example, $0,$1 will change the 4 bytes ahead as the specified 2 bytes value.
 
'0x' Is like '+' a symbol that modifies succeeding values. 0x0 goes 2 bytes ahead and changes them, 0x1 goes 4 bytes ahead and so on and so forth.
 
'-' or '+' Changes the specified preceding or succeeding 2 bytes of VU0 mpg cycles' offset according to the added number. Adding -1, for example will change the 2 bytes before it. Likewise, adding -2 will go 4 bytes away and change the specified 2 bytes accordingly. It even can change EE cycle scalar itself at -15 (Jakv2).

<pre>COP2, Also known as VU0 Macro-mode. these commands "may" only be useful for games that use M-bit</pre>
<pre>The SIF is how the EE and IOP communicate with each other. SIF has some mailbox hardware registers that the CPUs can use to pass values to each other, which happens during SIF initialization. However, once both sides have booted, they use the SIF0 (IOP->EE) and SIF1 (EE->IOP) DMA channels to communicate. Despite common belief, these commands have no effect on performance, and are rarely ever useful.</pre>

====( SIF )====
====CDVD====
<pre>The SIF is how the EE and IOP communicate with each other. SIF has some mailbox hardware registers that the CPUs can use to pass values to each other, which happens during SIF initialization. However, once both sides have booted, they use the SIF0 (IOP->EE) and SIF1 (EE->IOP) DMA channels to communicate. Despite common belief, these commands have no effect on performance.
 
but they could help with fixing many games that are still unplayable due to Syncing issues</pre>

=== Emulators ===


<pre>It is the most powerful Configuration on the emulator, it Allows direct patching of EE/IOP/VU memory, hooks registers, hook dma, '''almost Everything can be done here'''.  
Every PS2 emulator is programmed differently. Sometimes choosing the right emulator is the only way to fix a game. Emulators are not provided pre-installed in the PS4 OS, but instead they have to be unpacked from an official PS2 CLASSICS PKG file signed by Sony. This list includes the typical usage of those emulators.


If needed it can hook registers by using register names from alias files. Alias files (ee-cpr0-alias.lua, ee-gpr-alias.lua, ee-hwaddr.lua) are stored in lua_include folder, and can be included to config by using require ( "alias file name" ).</pre>

emuObj.LoadFsShader(1, "./shader.sb")
end
 
That only load Fragment Shader to program memory, to use it we need BindFragmentShader,
and if depend on shader SetShaderParams.</pre></div>

This register most of times will hold last executed syscall address,

Unlike the pc, this one doesn't change after a crash and has much lower latency.
Thus meaning it's better at diagnosing problems.</pre>

| Missing COP2 pipeline emulation. || [https://github.com/PCSX2/pcsx2/issues/4439 other games affected by COP2 timing] || Rearranging code through lua patches. || While COP2 is a part of EE, in terms of emulation it's a separate processor that can run on its own. Consequently, some operations take a long time while EE still minds own its business. Some games abuse this and do their own thing, knowing that COP2 calculation takes an expected number of cycles. On this emu, every COP2 opcode is instant, which break games that expect it to take some time.

Most of the time, it will be CTC2/QMTC2 instructions with interlock that are affected. || Emulator kickstarts VU0 for 256 cycles, while reporting that 512 cycles passed. Yup, we are out of sync right from the start of VU0 mpg because people working for $ony don't know that VU0 run at EE MHz, not at EE bus MHz. Not to mention, that a 256 cycles kickstart is too much even on the correct speed. Later things just got worse. This issue can be partially replicated on Pcsx2 if you overclock the EE by +3

<br>It's worth noting that pcsx2 by default applies "accurate add/sub" for every single FPU opcode, and only to fpu opcodes. That's why accurate add/sub is needed on the PS4 while pcsx2 is happy with its default settings.

The PS2 BIOS is the file '''PS20220WD20050620.crack''' included in every PS2 game .pkg. It is the same BIOS used by Sony in PS3's ps2_netemu.self. The lack of many X modules here means that homebrew compatibility is limited, as many of those need to be recompiled to use non X versions of modules, or need to load open source versions of them through MC/CDVD. An important non X module that is missing is LIBSD, therefore, homebrews that require it will likely fail to boot, or cause an error.
'''Making a lua'''
<pre>
When making a lua there is 1 part that is always necessary (Apirequest)
and 2 parts that are almost always necessary (Object) (Object's commands).
By order it goes like this:
1. Apirequest
2. Object calling, gsobj/eeobj/iopobj, etc
3. the object's command
You cannot call an object without first requesting an api, as that will cause a crash.
and you most certainly cannot use an object's command without calling the object first


For instance you cannot use
This PS2 BIOS is known to blacklist some titles, and refuse to boot them. This includes all titles with the 00000000 000000A0 flag, documented [[PS2_Emulation#Game_ID/DiscID in PS20220WD20050620.crack|here]].

<pre>
-- You can make a comment in a lua by using two hyphens (--)
The version of the PS2 BIOS seems to be the developement v2.20 from the Japanese region (22/01/2007), and is not limited to booting only NTSC-J games.
-- Your comments will be ignored by the lua
The PS2 emulator does not support USB peripherals, but this seems not to be a limitation of the BIOS, as it is used also in CECH C/E PS3 consoles.
-- author=refraction
There are signs that different PS2 BIOS versions exist, named PS20190AC20030623_nordram_miniOSD.bin. This PS2 BIOS has included handy extensions for debugging, and can debug print with "debug osd verbosity" from CLI set to "verbose". The most noticeable difference for both BIOS files seems to be the special RDRAM module.

Whilst the PS3 patches its PS2 BIOS to preferred regions, the PS4 uses a so called CallHook which is better known for PCSX2 users as fastboot. For more information about this patch, look at PCSX2's fastboot code. It is the same code except that PS2 emulators for PS4 do not have patches for different BIOS revisions.

==Description==
 
The PS2 bios is the file '''PS20220WD20050620.crack''' included in every PS2 game .pkg. It Is '''exactly''' the same BIOS that Sony used in ps2_netemu.self in PS3. Due to lack of many X modules homebrew compatibility is limited, and many of those need to be recompiled to use non X versions of modules, or need to load open source versions of them thru mc/cdvd. Important non X module that is missing is libsd, and homebrew that need it, will most likely fail to boot, or error.

<br>'''More about the bios'''
<pre>
Bios version seems to be Developement v2.20 from Japan region (22/01/2007), but it's of course not limited to booting only NTSC-J games.
Emulator not support USB peripherals, but this seems to be not limitation of BIOS, as it is used also in CECH C/E PS3 consoles.
There are signs that different bios version exist, named PS20190AC20030623_nordram_miniOSD.bin. This bios have included handy extensions for debugging, and can debug print with "debug osd verbosity" from CLI set to "verbose". Most noticeable difference for both bios files seems to be special RDRAM module.
 
While PS3 emulators patch bios to preferred region, emulator used in PS4 use so called CallHook which is known better for pcsx2 users as fastboot. No need to describe patch here, just look at PCSX2 fastboot code. It's literally the same code, but PS4 emus don't have patches for different bios revisions.

Description[edit | edit source]

The PlayStation 2 emulation on the PlayStation 4 is handled with little difference to the PlayStation 3. Some issues on PS3's PS2 emulator were left unfixed on the PlayStation 4. Consequently, the PS4 inherited some of PS3's emulation glitches, and even introduced new ones. The new issues came as a result of PS4's weakness with emulation, which likely resulted in the trade of accuracy for performance.

Each PS2onPS4 package file (.pkg) includes the PS2 emulator itself. The PS4 does not have a native built-in emulator in its System Software, but it does have a few PS2 emulator specific features, like the usermode functions sceLncUtilIsPs2Emu, sceShellCoreUtilGetImposeMenuFlagForPs2Emu, sceSystemServiceAddLocalProcessForPs2Emu, and sceSystemServiceShowImposeMenuForPs2Emu.

The PS2 emulators are programmed to be accurate for the games they were designed to emulate. In turn, this makes accurate emulation challenging, as emulators include per-title patches and different default settings. The PlayStation 2 hardware is a complex system to emulate; any small change in configuration can make or break a game. Currently, the most commonly used emulator is "Jakv2" from Jak games, as it is the most compatible one out there. When game crashes are concerned in an emulated PS2 game, then the Resident Evil Code: Veronica X's emulator is typically used, whereas for VU accuracy it is Rogue Galaxy's.

The PS2 BIOS is included in the game's pkg file. It is the same PS2 BIOS as used in the ps2_netemu in PS3 Operating System. The lack of encryption mechanism for PS2 game disc image files is also huge. This time, it is a plain ISO file, but the emulator still supports LIMG sector that allows the usage of non-2048 sector size discs. Moreover, memory cards are also unencrypted, but the emulator checks the CRC of some of the regions to ensure that the memory card was not modified. The PS2 emulator on PS4 also supports LUA scripting by a "Lua Bridge", which is a powerful interface that may prove exceptionally handy in fixing games.

This is first time that Sony has ever cared about floats in its emulators. Compared to the PS3 CPU, x86-64 is doing a worse job in mimicking FPU and VU floats calculation behavior. This is resolved by clamping, accurate math used per memory offset, and/or converting floats to double precision. The emulator uses OpenCL for GS, and likely other components as well.

Emulator Configuration[edit | edit source]

The emulator can be configured through 4 files.

Files[edit | edit source]

  • config-emu-ps4.txt - Stores paths, basic video/audio settings in official packages. But unofficially can be also used for advanced settings for global effect in multi disc .pkg with all commands originally used in cli.conf file.
  • XXXX-YYYYY_cli.conf - Stores per disc advanced settings. GS, VU, EE, IOP, FPU, COP2 emulation settings, are here. Also hacks, and hooks.
  • XXXX-YYYYY_config.lua - Used for per disc advanced scripts. Patching EE/IOP memory, Conditional hooks.

All functions for 2A, 2B, 2C, 2D must be redirected to ports on multi-tap 1 by using memory patches. --mtap2=always

XXXX-YYYYY_cli.conf commands[edit | edit source]

These commands work in config-emu-ps4.txt, but the official way to use them is through the CLI file (It is also needed for multi-disc packages). Additionally, some commands are still not discovered, and known commands might be missing their values.
All commands are pre-made. Creating new CLI commands is impossible.
The values of the commands are also pre-defined by Sony and/or have a set of possible values or ranges.
Some CLI commands have no effect, as they were added to the eboot.bin without being programmed. Some useful commands were removed or added in or from different emu revisions, or their effects were changed. In some emulators, CLI configurations can be found in the ram at SceLibcHeap[0]-3-881004000.

EmotionEngine (MIPS-IV)[edit | edit source]

EE[edit | edit source]
Commands for the emulated Emotion Engine. These commands may improve performance, prevent crashes, or provide better core sync.
Command Values Notes Usage
Speedhacks / Desync Fixes
--ee-cycle-scalar Slowest cycles speed: 5.00
Normal cycles speed: 1.000
Fastest cycles speed: 0.100		 Can benefit core sync or performance (lowering the cycle rate may affect FMVS). The default value for most emulators is ~1.0. It is highly sensitive, as any slight change may break or fix the game. (Possibly divides 100 with the entered value and sets the result as EE's clock speed percentage % .) --ee-cycle-scalar=1.0
--ee-context-switch-cycles Accelerate cycles (360 => 0)
Decelerate cycles (361 => ∞ )		 Its effects are mysterious. Possibly configures how many CPU cycles the emulator should run before switching between different tasks or threads. Does not work on Jak emulators. Default value is 360. Seems to be useful for Bee Movie, Metal Gear Solid 3, as well as others with IPU issues. --ee-context-switch-cycles=2700?
--ee-hook AdvanceClock
FastForwardClock
Mfifodrain		 Runs the specified functionality each time a selected EE offset is reached. FastForwardClock and AdvanceClock help fix core sync issues, but can be used as a speedhack. It is believed that AdvanceClock stalls the EE for a specified amount of cycles, while FastForwardClock behaves similarly. They are commonly used on affected COP2 instructions. Mfifodrain is still unknown. For more examples --ee-hook=0x0025A9F2,AdvanceClock,,500

FPU[edit | edit source]
The FPU is a fast single-precision unit that typically serves the EE by calculating in-game physics. It mostly controls the accuracy of the movement of in-game objects, or the game's gravity as a whole. In some cases, it is best to use COP2 commands with the FPU's to ensure the accuracy of the game's geometrical calculations.

Vector Units (VU)[edit | edit source]

VU[edit | edit source]
Custom DSPs used to process vertex data, physics calculations, and other related tasks. Settings found here affect VU1, VU0, and COP2. They fix broken or missing geometry, black screens, and crashes.
Command Values Notes Usage
Graphical fixes
--vu-xgkick-delay Limit is between (0 => 31) Delay xgkick instruction execution. PCSX2 uses 6 cycles, PS3 uses 2-8 cycles depending on the game. A game with missing graphics will require a low value such as 0, while one that crashes might require a high value such as 7. --vu-xgkick-delay=8
--vu-custom-min-max 0, 1 Custom Max/Mini logic for denormals. Disabled on pcsx2 by default but enabled by default on a couple of emus such as jakv2. Disabling it could potentially restore missing graphics. --vu-custom-min-max=0
Game fixes
--vu-hack-triace 0, 1 A hack designed specifically for games developed by Tri Ace. Corrects the VU's addi calculation. Without it, the result will be one bit off, which is enough to break the game's decryption algo. --vu-hack-triace=1
--vu-branch-hazard 0, 1 This command relates to how the emulator handles branch hazards in the Vector Units (VU). Setting it to 0 is the compatible option, while 1 might improve performance. Seems to be enabled by default. Disabling it managed to prevent "Batman - Rise of Sin Tzu" from crashing --vu-branch-hazard=0

VU1[edit | edit source]
VU1 is the Graphics Synthesizer’s alternate processing unit. Commands here typically improve performance, prevent crashes, and fix SPS (graphical glitches).
Command Values Notes Usage
Speedhacks
--vu1-mpg-cycles Decimals
0 - 65535		 Set initial speed for VU1 Micro-programs. 100 is the default value. If VU1 requirements were a bottleneck, increasing it will result in better performance while decreasing it will result in the opposite. Increasing it can be beneficial for MTVU sensitive games. --vu1-mpg-cycles=1000
 Symbols (They change values close to VU1-mpg-cycles' offset):

$ goes to the specified succeeding offsets. $0 will go 2 bytes forward and change them. $1 will go 4 bytes forward and change the 2 bytes specified. For example, $0,$1 will change the 4 bytes ahead as the specified 2 bytes' value.

'0x' Is like '+' a symbol that modifies succeeding values. 0x0 goes 2 bytes ahead and changes them, 0x1 goes 4 bytes ahead and so on and so forth. 

'-' or '+' Changes the specified preceding or succeeding 2 bytes of VU1 mpg cycles' offset according to the added number. Adding -1, for example will change the 2 bytes before it. Likewise, adding -2 will go 4 bytes away and change the specified 2 bytes accordingly. It even can change EE cycle scalar itself if you go far enough. These numbers are in HEX. Infinite amounts of '-' and '+' symbols seem to be supported.
--vu1-di-bits 0, 1 0 Skips setting invalid, and Divides by zero flags in status register. Can be used as a speedhack as it can skip costly calculations. But at the same time, it can cause issues such as broken geometry. --vu1-di-bits=0
--vu1-const-prop 0, 1 Enabled by default. 0 will disable it and cause performance issues but with higher compatability.More info --vu1-const-prop=1

--vu1-injection 0, 1 unknown --vu1-injection=1
--vu1-native-patch 0, 1 Use native patches from recompiler, not compatible with jak emus. Sony uses it for their official release of Primal --vu1-native-patch=1
Other
--vu1-inst-p 0, 1 instant P, no stalling on WAITP, or instances of P --vu1-inst-p=1
--vu1-use-rcp 0, 1 Use SSE/AVX RCP. Speedhack. Likely used only in EFU pipeline, due to rare use, its really not worth to enable it. Speed improvement will be marginally/unnoticeable. Disabled by default
--vu1-use-rsqrt 0, 1 Use SSE/AVX rsqrt instead of doing sqrt and then div. Speedhack, rather safe to use on VU1.
--vu1-clamp-operands 0, 1 Clamp operands before mathematical operation. --vu1-clamp-operands=1
--vu1-clamp-results 0, 1 Clamp result after mathematical operation. --vu1-clamp-results=1
--vu1-inst-q 0, 1 instant Q, no stalling on WAITQ, or instances of Q. --vu1-inst-q=1
--assert-path1-ad 0, 1 Path 1 is how the GIF takes data from VU1 via XGKICK instruction. It's unknown what this command does but it's related to VU1, and helps prevent crashes in VU1 sensitive games when enabled. --assert-path1-ad=1
VU0[edit | edit source]
VU0 is the Emotion Engine’s alternate processing unit. It is sometimes referred to as "micro-mode". Commands here prevent crashes, and fix SPS (graphical glitches).
Command Values Notes Usage
Speedhacks
--vu0-mpg-cycles Decimals
0 - 65535		 Set initial cycle speed for VU0 Micro-programs. 100 is the default value. It is not available in older emulators such as War of the Monsters. Raising the value helps COP2 timing, while lowering does the opposite. --vu0-mpg-cycles=1000
 Symbols (They change values close to VU0-mpg-cycles' offset):

$ goes to the specified succeeding offsets. $0 will go 2 bytes forward and changes them. $1 will go 4 bytes forward and changes the 2 bytes specified. For example, $0,$1 will change the 4 bytes ahead as the specified 2 bytes value.

'0x' Is like '+' a symbol that modifies succeeding values. 0x0 goes 2 bytes ahead and changes them, 0x1 goes 4 bytes ahead and so on and so forth. 

'-' or '+' Changes the specified preceding or succeeding 2 bytes of VU0 mpg cycles' offset according to the added number. Adding -1, for example will change the 2 bytes before it. Likewise, adding -2 will go 4 bytes away and change the specified 2 bytes accordingly. It even can change EE cycle scalar itself at -15 (Jakv2). Setting it to --vu0-mpg-cycles=1280,-15 would, for example, set ee-cycle-scalar to 5. These numbers are in HEX. Infinite amounts of '-' and '+' instances seem to be supported.
--vu0-di-bits 0, 1 0 to skip setting invalid, and Div by zero flags in status register. Can be used as speedhack as it skips costly calculations, but at the same time can cause issues like broken geometry, and weird physics behavior. Depending per game. --vu0-di-bits=0

DMA Channels[edit | edit source]

VIF[edit | edit source]
The VIF decompresses vector data, uploads microprograms to the VUs, and sends graphical data to the GIF. Its commands
are often used to fix freezing.
Command Values Notes Usage
VIF Game fixes
--vif-ignore-invalid-cmd 0, 1 Ignore invalid vif commands. In some cases, setting it to 1 can fix games that freeze while showing the same frame. --vif-ignore-invalid-cmd=1
--vif-thread-chunk-size 0, 1024 Slows down both VIFS the lower it is, and speeds them up the higher it is. 1024 is the limit, with 112 being the default value.  --vif-thread-chunk-size=100
--detect-idle-vif 0, 1 Enabled by default. Unknown function --detect-idle-vif=0
VIF1 Game fixes
--vif1-ignore-cmd-ints 0, 1 Set to 1 to ignore command interrupt bit. (info , explanation of int bit is right before command list). Can in some cases fix games that freeze while showing the same frame if set to 1. Games likes "Men in Black II - Alien Escape" and "Test Drive Unlimited" Will always need it. --vif1-ignore-cmd-ints=1
--vif1-instant-xfer 1 = Instant VIF1
0 = Delayed VIF1		 Changes VIF1 timing. 0 slows its timing and is the compatible option for most games, while 1 speeds up its timing, and being more compatible with a small fraction of games. It can be used to fix graphical glitches or potentially prevent games from freezing. --vif1-instant-xfer=0
SIF[edit | edit source]
The SIF is how the EE and IOP communicate with each other. SIF has some mailbox hardware registers that the CPUs can use to pass values to each other, which happens during SIF initialization. However, once both sides have booted, they use the SIF0 (IOP->EE) and SIF1 (EE->IOP) DMA channels to communicate. Despite common belief, these commands have no effect on performance, and are rarely ever useful.
Command Values Notes Usage
SIF1 (IOP)
--iop-sif1-cycle-scalar Accelerate SIF cycles: (0.99 => 0.1)
Decelerate SIF cycles: (1.1 => ∞ )		 Controls the speed at which the IOP receives from the EE --iop-sif1-cycle-scalar=0.1
--ee-sif1-cycle-scalar Accelerate SIF cycles: (0.99 => 0.1)
Decelerate SIF cycles: (1.1 => ∞ )		 Controls the speed at which the EE sends to the IOP --ee-sif1-cycle-scalar=0.1
SIF0 (EE)
--iop-sif0-cycle-scalar Accelerate SIF cycles: (0.99 => 0.1)
Decelerate SIF cycles: (1.1 => ∞ )		 Controls the speed at which the IOP sends to the EE --iop-sif0-cycle-scalar=0.1
--ee-sif0-cycle-scalar Accelerate SIF cycles: (0.99 => 0.1)
Decelerate SIF cycles: (1.1 => ∞ )		 Controls the speed at which the EE receives from the IOP --ee-sif0-cycle-scalar=0.1

GS[edit | edit source]

"GS" stands for Graphics Synthesizer. It's the PlayStation®2's co-processor that's responsible for rendering the graphics (but is also used by some games for additional calculations and other purposes)
Command Values Notes Usage
Speedhacks
--gs-optimize-30fps 0, 1 Speedhack for GS hungry games. --gs-optimize-30fps=1
--gs-adaptive-frameskip 0, 1 Speedhack. Skips frames when the gs demands more resources than there are available. doesn't work on all emulators. It does however, work on jak emulators --gs-adaptive-frameskip=1
--gs-h2l-list-opt 0, 1 Setting it to 1 improves GS performance --gs-h2l-list-opt=1
GS features
--gs-use-mipmap 0, 1 Enables mipmapping support. Can be used to fix graphics. Needs --gs-kernel-cl="mipmap" for full mipmapping support. If upscaling, however, --gs-kernel-cl-up="mipmap2x2" is also needed. It works best on War of the Monsters emulator, as can be seen in the Ratchet series' mipmapping issues responding only to this emu's mipmapping functionality. --gs-use-mipmap=1
--gs-use-deferred-l2h 0, 1 Delay option for L2H (local to host, GS to EE). --gs-use-deferred-l2h=1
--gs-use-clut-merge 0, 1 Enabling CLUT merging helps improve how the emulator processes textures that use indexed color palettes. It ensures more accurate emulation of the PS2’s color handling. It sometimes restores missing graphical elements, and fix texture flickering (prominently flickering shadows or UI elements). It prevents Spyro's shadow from flickering in Enter the Dragonfly. Enabling it is the accurate, albeit slow option. --gs-use-clut-merge=1
--gs-flush-ad-xyz always, safe, safeZwrite, off, 0 Force a primitive flush when a framebuffer is also an input texture. This fixes some processing effects, but it can sometimes be heavy on the GS in terms of performance. GTA: SA, and Jak 3 use this command. --gs-flush-ad-xyz=safe
--gs-force-bilinear 0, 1 Forces bilinear filtering, can fix ghosting problems in some cases. Not recommended for games that use 2D images, as it could possibly break games that rely on nearest filtering. --gs-force-bilinear=1
Gs settings / Behaviour
--gs-uprender none,2x2 Internal resolution upscaler. --gs-uprender=2x2
--gs-upscale none, gpu, edgesmooth, smooth, motion, motionvec, motionvector, point Upscaling type Selector --gs-upscale=EdgeSmooth

--gs-override-small-tri-area 0, 1 This option is designed to modify how the emulator handles or renders small triangles that fall below a certain area threshold. Enabling this option could resolve graphical problems such as missing, flickering, or incorrectly rendered small details, and could potentially restore missing text in some games. --gs-override-small-tri-area=1
--gs-dirty-page-policy 0, 1 Unknown. Used by Star Wars: Jedi Starfighter --gs-dirty-page-policy=1
--gs-ignore-dirty-page-border 0, 1 Unknown. Used by Samurai Shodown Anthology --gs-ignore-dirty-page-border=1
--gs-ignore-rect-correction 0, 1 Setting it to 1 is known to fix flickering textures and graphical glitches in far distances. --gs-ignore-rect-correction=1

--gs-kernel-cl h2lpool, clutmerge, mipmap, DarkCloud2, fantavision, Mipmap and clutmerge and h2l need to be enabled before their options become usable Kernel Variant Color lookup(?). Options included here can be upscaling if --gs-kernel-cl-up were to be used along with it --gs-kernel-cl="clutmerge"
--force-frame-blend 0, 1 Enables blend (Deinterlacing?). Should be used to fix games with shaking screens. --force-frame-blend=1
--force-pal-60hz 0, 1 Enables 60hz PAL mode. --force-pal-60hz=1
--gs-progressive 0, 1 Enables progressive scan. Can fix graphical glitches/double screen issues.
--gs-vert-precision 8, 16 This option allows the user to choose between 8-bit and 16-bit precision for the vertex calculations in 3D graphics rendering. It reduces the likelihood of visual distortions such as jagged edges, improper alignment of polygons, or model "warping." The emu expects the values of 8 or 16, any other values are not permitted. --gs-vert-precision=8
--gs-skip-dirty-flush-on-mipmap 0, 1 Skip flushing textures marked as dirty from cache when enabled. It does, however, require mipmap to be enabled first. --gs-skip-dirty-flush-on-mipmap=1
--gs-packed15-fmv-opt 0, 1 Unknown. This option likely controls whether the emulator optimizes or processes FMVs that use the 15-bit packed color format. Used by Ape Escape 2 --gs-packed15-fmv-opt=1
--gs-fieldswap-delay 0, 254 Wait longer than usual to change field. In essence, it blurs/sharpens image.

IOP[edit | edit source]

The emulated I/O Processor (IOP) settings. Commands here are rarely useful, as very few games will require them. The IOP controls the emulated DEV9, SPU2, USB, Memory cards, CDVD, Firewire, along with other input/output devices
Command Values Notes Usage
Game fixes
--iop-cycle-scalar
Accelerate IOP cycles: (0.999 => 0.100)
Decelerate IOP cycles: (1.001 => 5.000)		 Not a performance speedhack. It impacts the speed of loading times and input latency. The default value for most emulators is 0.5 --iop-cycle-scalar=1.0
--iop-const-folding None,Gpr,All IOP constant folding More info --iop-const-folding=All
--iop-tight-slice-count 0, 2000 Seems to slow down the iop the higher the value. Can be used to fix CDVD timing issues. --iop-tight-slice-count=12

CDVD[edit | edit source]

The emulated CDVD settings. These commands help games with timing issues.
Command Values Notes Usage
General commands
--max-disc-num 1-5 numbers of discs in package (maximum=5) --max-disc-num=1
--boot-disc-id 1-5 sets boot disc for multi-disc pkg --boot-disc-id=0
--switch-disc-reset 1 = Enables resetting the game upon disc swap, 0 = Disables resetting the game upon disc swap 0 Can be used to prevent resetting the game when switching multiple discs. Useful for games like Samurai warriors 2 that include an import data feature. Sadly this command isn't supported by many emulators, but jakv2 is confirmed to support it --switch-disc-reset=1
Timing
--cdvd-sector-read-cycles 0.1 = Fastest, 80000 = Slowest Set DVD reading speed. Higher values are slower, lower values are faster. Kinetica uses 40000, Psychonauts 4000, Red dead revolver 5000, Rise of kasai 31000. Some games require moderate speed, too slow or too fast could cause audio problems. --cdvd-sector-read-cycles=0.1
--cdvd-sector-seek-cycles 0.1 = Fastest, 80000 = Slowest Set the speed at which the emulated CDVD spins. Higher values are slower,

lower values are faster. Fixes boot-up sometimes. More info here [1].

--verbose-cdvd-reads 0, 1 Significantly helps games with CDVD timing issues when set to 1. --verbose-cdvd-reads=0

Emulators[edit | edit source]

Every PS2 emulator is programmed differently. Sometimes choosing the right emulator is the only way to fix a game. Emulators are not provided pre-installed in the PS4 OS, but instead they have to be unpacked from an official PS2 CLASSICS PKG file signed by Sony. This list includes the typical usage of those emulators.

Emulator name Typical usage - Info API Version Similar emulators
2018
The King of Fighters '98: Ultimate Match The only known emulator where Mojin-ribbon is playable. Commonly known as "KOF98" 2.0
2017
Jak and Daxter: The Precursor Legacy Good compatibility with most ps2 games. It has a very high api version which means more LUA commands are supported. In addition, Jak emus are one of the few emus that can use the --gs-adaptive-frameskip=1 command. It is often referred to as "Jak v2" 2.2 JakX, Jak 2, Jak 3,
Art of Fighting Anthology Similar to RECVX. It was successful in fixing "Coraline." Sometimes called "AOFA" 2.0
Resident Evil - Code: Veronica Fixes games like Jackie chan Adventures, SpongeBob SquarePants: Creature From the Krust Krab, Pac-man World 3, Yu-Gi-Oh: Capsule monsters, SpongeBob's Atlantis SquarePantis freezing at a black/splash screen. Additionally, it fixes many games requiring OPL's mode 2. Often referred to as "RECVX" 1.7 Fatal Fury, Redfaction, AOFA.
Fatal Fury Battle Archives: Volume 2 Similarly to RECVX, it is often used to fix frozen games.
2016
Red Faction It is prominently used to fix VU1 sensitive games. It was used to fix Tony Hawk games suddenly crashing, as well as MTVU sensitive games such as Star Wars Battlefront II. 1.6 Max payne
Forbidden Siren The only emulator to fix Ice age 2 being stuck at splash screen. It also fixed Gran turismo 4 running abysmally slow. 0.1
King of Fighters 2000 Seemingly one of the most VU-accurate emus, fixing sps in games such as Crash Twinsanity, Rayman 3, Crazy Frog Racer. It also prevents Koei tecmo games from suddenly freezing when battle starts. Moreover, it is likely the only emulator where Batman Begins does not crash. Often referred to as "KOF2000" 1.2 Roguev1, KOF98, Okage
Destroy All Humans! Fixed Tenchu: Fatal Shadows' crashing. 0.1
Destroy All Humans! 2 0.7
Rise of the Kasai It fixed most of the Harry Potter games. Often referred to as "rotk". 0.2
2015
War of the monsters v1 Subjectively the best emulator to use. Used as PS2CLASSICSGUI's default emulator, it is the best one around for accurate gs emulation, as some graphical issues on the Ratchet series and Tekken 5 can only be fixed by it. Another interesting case is GTA SA's lack of need for auto flush on it, and being natively performant. Additionally, its VU0 timing is much better than Jakv2's, making it one of the best emulators on the PS4. 0.1 Rogue v1 and v2, Arc the Lad, Star Wars Jedi Starfighter
GTA III Fixed the PAL version of Genji: Dawn of the Samurai. 0.6
PaRappa the Rapper 2 The only emulator to boot Spyro: A Hero's Tail. 0.1
Star Wars Racers Revenge Seemingly the closest emulator to the PS3's. Useful for debugging games as it also shows useful information such as pagefault. 0.4

XXXX-YYYYY_config.lua[edit | edit source]


It is the most powerful configuration on the emulator, it allows for direct patching of EE/IOP/VU memory, hooks registers, hook dma. Almost Everything can be done here.
If needed it can hook registers by using register names from alias files. Alias files (ee-cpr0-alias.lua, ee-gpr-alias.lua, ee-hwaddr.lua) are stored in lua_include folder, and can be included to config by using require ("alias file name").
Known functions: Require cleanup.

ApiRequest[edit | edit source]

The most important part of the LUA script. The LUA script will crash the game if used without it.
Command Usage Notes
apiRequest apiRequest(0.1) apiRequest(<api version>)

Different emu versions support different highest api. Calling api is mandatory. some commands require higher version. Highest known version is 2.3 api from JAK 2,3,X game emulator.

ForceRefreshRate emuObj.ForceRefreshRate(<hz>) emuObj.ForceRefreshRate(50) correct values are 0, 50, 60 where 0 = default.
LoadFsShader emuObj.LoadFsShader(<slot?>, "<path>") 
Shaders must be loaded right after GS has been initialized. 
Example:
Global_InitGpuResources = function()
	emuObj.LoadFsShader(1, "./shader.sb")
end

That only load Fragment Shader to program memory, to use it we need BindFragmentShader, 
and if depend on shader SetShaderParams.

ReadMemStr eeObj.ReadMemStr(address/register) Read string from address until null terminator
WriteMemStr eeObj.WriteMemStr(address, string)
WriteMemStrZ eeObj.WriteMemStrZ(string pointer, string) . Pointer can be read from GPR
GPR require (Necessary for register related commands)
local gpr = require( "ee-gpr-alias" )
GetGpr64 eeObj.GetGPR64(<gpr register>) example: eeObj.GetGPR64(t3)
SetGpr64
GetGprFloat Get gpr value as float value
SetGprFloat Set gpr value as float value
GetGpr eeObj.GetGPR(<gpr register>) eeObj.GetGPR(t3)
SetGpr eeObj.SetGPR(<gpr register> ,<value>) example: eeObj.SetGPR(gpr.a3 ,1)

Require defined getEEObject() as eeObj

SetFprHex eeObj.SetFprHex(<FPU register (0-31), value (u32)>) Set floating point register value as hex string
GetFpr eeObj.GetFpr(<register number>) example eeObj.GetFpr(14)
SetFpr eeObj.SetFpr(<fpr register number>, <value>) Simple example eeObj.SetFpr(14, 50.0) will set frp 14 to 50.0

But we can also combine commands to add/sub from registers eeObj.SetFpr(14, eeObj.GetFpr(14) + 50.0) this will add 50.0 to current fpr 14 value

GetPc eeObj.GetPc() This command is very helpful as it will return to you the current EE address that's being read. Can be used also with additional var. like eeObj.GetPc()+4
SetPc eeObj.SetPC(<PC>) eeObj.SetPC(0x266B80)
GetCPR0 eeObj.GetCPR0(<COP0 register>)
SetCPR0 eeObj.SetCPR0(<COP0 register>)

eeObj.AddHook(0x002cc350, 0x78a30000, function()
          eeObj.AdvanceClock(21000)
end)
GetClock eeObj.GetClock() Returns the value of how many cycles the EE is ahead of normal clock (?)
Vu1MpgCycles eeObj.Vu1MpgCycles(<cycles>) Works just like the cli command --vu1-mpg-cycles=
Other
CallPredicate

Example:
eeObj.AddHook(0x0033A4DC,0xAC430000, function() eeObj.SchedulerDelayEvent("gif.dma", 0x10500) end)		 Parrapa use eeObj.SchedulerDelayEvent("vif1.dma", 0x6500) other events are gif.dma, vif0.dma, vif1.dma, sif0.dma, Sif0-NormalTransfer, sif1.dma, Sif1-NormalTransfer, ipu0.dma, ipu1.dma . This command allows for the delayment of certain DMA transfer by cycles.
WaitVu1 eeObj.WaitVu1() Likely to be the lua equivalent of "--vu1=jit-sync".
GetPcRingBuffer
Precompile Requires unknown values
CalcInsnHash
getOverlayObject eeObj.getOverlayObject() local eeOverlay = eeObj.getOverlayObject()
GetVif1Cycles eeObj.GetVif1Cycles() local vif1_cycles = eeObj.GetVif1Cycles() create vif_cycles value that can be used later. You can rename it as you wish.

Custom config.lua examples[edit | edit source]

Here is the first custom LUA configuration created by the community: 

apiRequest(0.1)

-- Fix black screen SLUS-20064

eeInsnReplace(0x1CF3CC, 0x4100ffff, 0x00000000)	-- bc0f 0x1CF3CC to nop

This is a very basic command to replace a part of the EE memory with another instruction.

  • apiRequest(0.1) - Is required for every config. Used version depend on your original eboot highest supported api. 0.1 seems to be enough for basic patches like here. 2.3 is highest known for now.
  • -- Fix black screen SLUS-20064 is comment
  • eeInsnReplace(0x1CF3CC, 0x4100ffff, 0x00000000) is our true command here. We are replacing the value 0x4100FFFF to 0x00000000 at the offset of 0x1CF3CC . Like you can see we need to add what opcode is replaced. Not only patch, and memory offset.
  • -- bc0f 0x1CF3CC to nop is just another comment, in this case explaining what is changed

Emulator related registers[edit | edit source]

"Fake" registers Address Notes
(?) 0x1000000360 Locking the value seems to cause a crash.
Current PC
(4 Bytes)		 0x1000000368 Shows the current offset that's being executed by the EE.

Updated only on branch/jump tests, unless commands such as --ee-pc-coherency or --ee-insn-flush-pc are used.
Then updates are instant, right when instructions are executed.
Commonly used by sceners as a way of finding troublesome offsets. Can be found in some emulators here too: 0x8000016830

(?) 0x100000036C 
Updated on branch/jump instructions, emulator seems to use it to store next address that will be executed.
At least in recompiler to interpreter fallback mode. During tests it shows 0x80000184
Delta counter 0x1000000370 
(Passed cycles, likely decrementer). 
Evt check is performed on branch test when 0.
Fastforwardclock set this to 0,
advanceclock subtract value from this fake reg)
Cycles 0x1000000378
(?) 0x1000000384 
Address when last exception occurred on r5900.
This register most of times will hold last executed syscall address,
sometimes last tlb miss or break(if "as nop" is disabled).
Unlike the pc, this one doesn't change after a crash and has much lower latency.
Thus meaning it's better at diagnosing problems.

PS3 Configuration support[edit | edit source]

The PS2 emulator of the PS4 supports configurations in the known format from ps2_netemu/ps2classic that came from the PS3. This feature was officially used in Arc the Lad Twilight of the Spirits ps2-ps4 classic. To enable PS3 style configuration, add this to config-emu-ps4.txt:

--lopnor-config=1
--ps2-title-id=TITLE-ID

The configuration file needs to be in folder ...'''/patches/{TITLE-ID}/''' and the file need to have name '''{TITLE-ID}_lopnor.cfgbin'''. The Title ID needs to be in XXXX-YYYYY format (ex. SLUS-12345). Example path: /patches/SLUS-12345/SLUS-12345_lopnor.cfgbin. A tester confirmed that configurations work as is without even the need to edit them.

Please keep in mind that not all PS3 commands are recognized, only 0x01 (can depend upon emu revision), 0x09, 0x0A, 0x0B, 0x0F, 0x10, 0x26, 0x27 and 0x42.
For example, the Rayman 3 configuration does not work due to the command being unsupported on PS4.
Command 0x07 is NOT recognized, but can be manually translated to CLI configuration (to "--vu-xgkick-delay=value").
Same goes for command 0x11 (--vu0-accurate-addsub-range can be used).

Known issues[edit | edit source]

Issue Games affected Solution Description
No support for EE Cache Ice Age 2, DOA2: Extreme, Nascar 2009, Barnyard, Others Lua patches to the EE memory and picking the right emulator
Missing COP2 pipeline emulation. other games affected by COP2 timing Rearranging code through lua patches. While COP2 is a part of EE, in terms of emulation it's a separate processor that can run on its own. Consequently, some operations take a long time while EE still minds own its business. Some games abuse this and do their own thing, knowing that COP2 calculation takes an expected number of cycles. On this emu, every COP2 opcode is instant, which break games that expect it to take some time.
VU0 is not running in sync with EE core 24 The Game, ATV Quad Power Racing 2, Ghosthunter, Rayman Arena, Rayman 3, Largo winch, Ratchet and clank games. All games using M-bit. EE hook AdvanceClock or fastforwardclock commands on affected addresses to push VU0 ahead while stalling EE, setting the value of 5 to ee cycle scalar, and patches to rearrange code. Most of the time, it will be CTC2/QMTC2 instructions with interlock that are affected. Emulator kickstarts VU0 for 256 cycles, while reporting that 512 cycles passed. Yup, we are out of sync right from the start of VU0 mpg because people working for $ony don't know that VU0 run at EE MHz, not at EE bus MHz. Not to mention, that a 256 cycles kickstart is too much even on the correct speed. Later things just got worse. This issue can be partially replicated on Pcsx2 if you overclock the EE by +3
FPU/VU math inaccuracies. Koun, Tony hawk games, Devil may cry 3, Gun, TY the Tasmanian Tiger 3, Beyond Good & Evil, MTX Mototrax, Max payne, Bully, Jackie chan adventures, Wild arms 3, Pac-man World 3, Gran turismo 4, Many others Lua patches to the EE memory, accurate math commands. PS2 use really obscure floating point math, only one guard bit is used in calculations. PCSX2 hack it with different rounding modes, emu on ps4 fix it with soft floats, usually applied per offset. Sometime with patches directly to affected code (THPS engine).


It's worth noting that pcsx2 by default applies "accurate add/sub" for every single FPU opcode, and only to fpu opcodes. That's why accurate add/sub is needed on the PS4 while pcsx2 is happy with its default settings.

M-Bit support is broken Every game that uses M-Bit. Totally Spies! Totally Party, Mike Tyson Heavyweight Boxing, My Street, Crash Twinsanity, Marvel Nemesis, Panzer Elite Action - Fields of Glory, Super Monkey Ball Adventure, most Eko Software games, and many more. [2] Lua patches to the EE memory While emulator respect m-bit, way that VU0 work on it make it broken most of times (check "VU0 is not running in sync with EE core" issue).
Multitap doesn't support all games Urban reign, Digimon Rumble Arena 2, others Lua patches Emulator expect PS4 to be able to use 8 controllers (well, who doesn't? Even PS1 can do it...). That cause all kind of mess with controller detection when game expect multitap in second port.
DMA writes when busy signal is engaged Ratchet and clank games, Metal gear solid 2, others None yet AKA eetiminghack
VIF1 runs too fast Urban reign, Avatar, Parappa 2, Eternal Poison, Soul Calibur 2, Soul Calibur 3, Others Using LUA's SchedulerDelayEvent command or Using CLI'S vif1-instant-xfer command Sony wanted to improve the performance, which is the reason VIF1 is instant. The lua's command can be customizable to set the delay period, the cli can't, therefore lua's command is much more compatible
Reading VU TPC registers returns wrong values Street Fighter 3 EX(VU0), R: Racing Revolution(VU0), Spiderman 3 (VU0, in T-Bit handler...), Edge of Reality games(VU1) Patches in lua. In this emu TPC stores full addresses, which is wrong. Real hardware keep there addr >> 3. Worth noting that EoR games read VU1 TPC in a nasty way, accessing 0x43A0(VU1 TPC) from COP2 code.
VIF command interrupts handled before VIFn_CODE is updated. Onimusha Blade Warriors Fixed by patch in intr handler. This is very specific case because Onimusha check VIFn_CODE register in interrupt handler and do nothing if code is not 0x80 (NOP with I). But VIFn_CODE seems to be updated after interrupt is handled. This practically makes everything out of sync later as interrupts are happening, but handler does nothing about them.
CDVD register 0x1F402038 (KeysValid) return wrong result. Every "SCCS" game Patches in lua. Likely specific to NTSC-C releases, because that region uses special SDK. This issue makes cdvdman become stuck on any request because it thinks that the cdvd key is invalid.
Lack of CDVD error handling Demon Chaos, Spyro A new Beginning, Silent Hill 2 Black Ribbon, games from pcsx2 #5174 PR. Patches in lua if needed. One correctly supported error is SCECdErABRT, rest is just not handled or what's worst trigger emu panic on purpose like SCECdErILI (but not for 0 sector request - Spyro). Some affected games can still work if error is just accidental and not checked by game code.
Corrupted SIF0 transfer when not full QW is send by IOP True Crime: LA, PDC DC 2008, Street Racing Syndicate(1.03) Patches in lua. IOP is able to send words by SIF0, EE DMAC can only transfer Quadwords. When IOP send not full QW real hardware use whatever was in buffer from previous transfer for missing words (only words that are requested by iop are overwritten in transfer buffer). Emu probably memset 0 that part.

PS2 Bios[edit | edit source]

Description[edit | edit source]

The PS2 BIOS is the file PS20220WD20050620.crack included in every PS2 game .pkg. It is the same BIOS used by Sony in PS3's ps2_netemu.self. The lack of many X modules here means that homebrew compatibility is limited, as many of those need to be recompiled to use non X versions of modules, or need to load open source versions of them through MC/CDVD. An important non X module that is missing is LIBSD, therefore, homebrews that require it will likely fail to boot, or cause an error.

This PS2 BIOS is known to blacklist some titles, and refuse to boot them. This includes all titles with the 00000000 000000A0 flag, documented here.

More about the PS2 BIOS 

The version of the PS2 BIOS seems to be the developement v2.20 from the Japanese region (22/01/2007), and is not limited to booting only NTSC-J games.
The PS2 emulator does not support USB peripherals, but this seems not to be a limitation of the BIOS, as it is used also in CECH C/E PS3 consoles. 
There are signs that different PS2 BIOS versions exist, named PS20190AC20030623_nordram_miniOSD.bin. This PS2 BIOS has included handy extensions for debugging, and can debug print with "debug osd verbosity" from CLI set to "verbose". The most noticeable difference for both BIOS files seems to be the special RDRAM module.

Whilst the PS3 patches its PS2 BIOS to preferred regions, the PS4 uses a so called CallHook which is better known for PCSX2 users as fastboot. For more information about this patch, look at PCSX2's fastboot code. It is the same code except that PS2 emulators for PS4 do not have patches for different BIOS revisions.

Game_ID/DiscID in PS20220WD20050620.crack[edit | edit source]

There are 193 titleIDs listed inside XPARAM2.ELF file of PS2 BIOS included in PS20220WD20050620.crack. XPARAM2.ELF is called by OSDSYS, then ID check is performed. If titleID match to one of included in the table, different IOP emulation settings are applied. This include blacklisting for some specific titles. 

The original PS2 BIOS from models with emulated IOP, include a similar list file called XPARAM.ELF. The Title IDs there are not the same, although some of them exist on both lists.
