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.
<pre>PlayStation 2 emulation on the PlayStaion 4 is handled with little difference to the PlayStation 3,
some issues that the PlayStation 3 encountered have moved on to the PlayStation 4, along with a few new ones.


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 PS4 is too weak for emulation, therefore Sony had to sacrifice accuracy for performance.


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.
Each PS2ONPS4 package file (.pkg) includes the emulator itself, the ps4 does not have a native built-in emulator in its firmware but it does have some PS2 emulator specific features, like the functions sceLncUtilIsPs2Emu, sceShellCoreUtilGetImposeMenuFlagForPs2Emu, sceSystemServiceAddLocalProcessForPs2Emu, or sceSystemServiceShowImposeMenuForPs2Emu.


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.
Emulators are programmed to be accurate for the games that they were made for, and that alone is a challenge for accurate emulation. since emulators include per title patches, and different default settings, and since the Playstation 2 hardware is a complex system to emulate, any small change in configuration can have make or break a game.


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.
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 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.

====FPU====
<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. In some cases, it is best to use COP2 commands with the FPU's to ensure the accuracy of the game's geometrical calculations.</pre>

=====SIF=====
====IOP====
<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>
<pre>The emulated I/O Processor (IOP) settings, Commands here are rarely useful, since the ps4 emulates it very accurately, very few games will require these options. the iop controls the emulated DEV9, SPU2, USB, Memory cards, CDVD, Firewire, along with other input/output Devices</pre>

====SIF====
|-
<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>

=== Emulators ===
 
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
|-style="background-color:#D7EF54"
|  || 2018 || ||
|-
|-
| The King of Fighters '98: Ultimate Match || The only known emulator where '''Mojin-ribbon''' is playable. Commonly known as "KOF98"|| 2.0 ||
|RemoveSnapshotLoadedHook || ||
|-
|-
|-style="background-color:#D7EF54"
|AddPadHook ||emuObj.AddPadHook() ||
|  || 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,'''
|-style="background-color:#ff8080"
|| Audio ||  
|-
|-
| Art of Fighting Anthology || Similar to RECVX. It was successful in fixing "'''Coraline'''." Sometimes called "AOFA" || 2.0 ||
|SetVolumes || emuObj.SetVolumes('global', 'main', 'bgm') || Set volume, usually setting global is enough. Example: emuObj.SetVolumes(0.31, 1.0, 1.0) values, in floats 1.0 = 100%
|-
|-
| 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.'''
|GetVolumes || emuObj.GetVolumes() || Return current volume levels for ('global', 'main', 'bgm') in floating point values.
|-
|-
| Fatal Fury Battle Archives: Volume 2 || Similarly to RECVX, it is often used to fix frozen games. ||  ||
|SetAudioRoute || ||
|-style="background-color:#D7EF54"
|  || 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'''
|GetAudioRoute || ||
|-style="background-color:#c2c2d6"
|  || Game loading speed ||  
|-
|-
| 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 ||
|ThrottleNorm ||emuObj.ThrottleNorm() || Enable default framelimiter (50/60 fps depend on region).
|-
|-
| 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'''
|ThrottleFast || emuObj.ThrottleFast() || Faster than default, but exact value is unknown.
|-
|-
| Destroy All Humans! || Fixed '''Tenchu: Fatal Shadows'''' crashing. || 0.1 ||  
|ThrottleMax || emuObj.ThrottleMax() || Disable framelimiter During loading screens, This setting can sometimes be harmful when used globally in config files. Loading times are faster, but the game also runs faster than it should when the PS4 has enough free cpu power.
|-style="background-color:#ffe680"
|  || CDVD ||  
|-
|-
| Destroy All Humans! 2 || || 0.7 ||  
|OpenDiscTray || ||
|-
|-
| Rise of the Kasai || It fixed most of the '''Harry Potter''' games. Often referred to as "rotk". || 0.2 ||
|CloseDiscTray || ||
|-
|-
|-style="background-color:#D7EF54"
|SwitchDisc || emuObj.SwitchDisc(<disc ID>) || ID can be provided as is, or for example read from memory or register when needed.
|  || 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'''
| GetDiscId || emuObj.GetDiscId() || Return DiscId in XXXX_YYY.ZZ format
|-
|-
| GTA III || Fixed the PAL version of '''Genji: Dawn of the Samurai'''. || 0.6 ||
| GetDiscTitleId || ||
|-
|-
| PaRappa the Rapper 2 || The only emulator to boot '''Spyro: A Hero's Tail'''. || 0.1 ||
|ShowDiscSwitchInfo ||emuObj.ShowDiscSwitchInfo() ||
|-
|-
| 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 ||  
|-style="background-color:#FEA15C"
| || Other ||

| EnableImposeMenu || emuObj.EnableImposeMenu(<true/false>) || EnableImposeMenu(false)
|-
|LoadConfig || ||
|-
|SaveConfig || ||
|-
|GetPad || emuObj.GetPad(<gamepad button by bits>)|| example usage for reading input:
<div align="left"><pre>local CheckInputs = function()


=== XXXX-YYYYY_config.lua ===
local pad_bits = emuObj.GetPad()
local UP = pad_bits &  0x0010
local DOWN = pad_bits &  0x0040
local LEFT = pad_bits &  0x0080
local RIGHT = pad_bits &  0x0020
local Triangle = pad_bits &  0x1000
local Cross = pad_bits &  0x4000
local Square = pad_bits &  0x8000
local Circle = pad_bits &  0x2000
local L1 = pad_bits &  0x0400
local L2 = pad_bits &  0x0100
local L3 = pad_bits &  0x0002
local R1 = pad_bits &  0x0800
local R2 = pad_bits &  0x0200
local R3 = pad_bits &  0x0004
local Select = pad_bits &  0x0001
local Start = pad_bits &  0x0008


<br>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 (L2 ~= 0) then
<br>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").
<here function that should be done when L2 is pushed>
<br>'''Known functions:

'''
Require cleanup.

To enable ps3 style config add this to config-emu-ps4.txt:


--lopnor-config=1

| No support for EE Cache || Ice Age 2, DOA2: Extreme, Nascar 2009, Barnyard, [https://github.com/PCSX2/pcsx2/issues/2248 Others]|| Lua patches to the EE memory and picking the right emulator ||  
| <pre>Suspected iop issue(?)</pre> || Zatch Bell! Mamodo Fury, Godfather, Gran turismo 4, SSX  || || a Stutter that's not caused by performance but by inaccurate iop emulation leading to stuttering fmvs/mainmenu
|-
|-
| 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.
| <pre> Suspected GIF issue (?) </pre> || <pre>Tenchu - Fatal Shadows, Genji dawn of the samurai, Batman begins, Lara Croft Tomb Raider - The Angel of Darkness, Dragon ball z budokai tenkaichi 1, Possibly many more! </pre>|| LUA patches ||

|-
| 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
| <pre>No support for EE Cache</pre> || <pre>Ice Age 2, DOA2: Extreme, Nascar 2009, Barnyard,</pre> [https://github.com/PCSX2/pcsx2/issues/2248 Others]|| <pre>Lua patches to the EE memory and picking the right emulator</pre> || <pre>It's not a ps4 issue per say since these issues are also encountered by Pcsx2. but Pcsx2 does have support for EE cache, though it doesn't use it to fix these games because emulating EE cache is extremely slow. so that's why the Pcsx2 team decided to use pnach patches to fix this issue.</pre>

| 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).
|<pre> VU0/COP2 is not running in sync with EE core </pre>|| <pre>24 The Game, ATV Quad Power Racing 2, Twisted Metal Head-On, Primal, Ghosthunter, Rayman Arena, Rayman 3, Largo winch.

<br>Worth to note that pcsx2 by default apply "accurate add/sub" for every single FPU opcode, and only to fpu opcodes. That why sometimes we need to use accurate add/sub while pcsx2 is happy at default settings.

|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.

| Inaccurate hsync rate/bad ipu timing || Bee movie, Never7, Tomb Raider: The Angel of Darkness, ESPN - NBA 2K5 || Underclocking/overclocking the EE, limiting the fps, and LUA patches. || Because the video goes out of sync either initially or midpoint, the game freezes at whatever frame it was at, repeating the exact same audio over and over again, or in some cases skipping parts of it and continuing normally. This is a timing issue that can be the result of more than one thing. As such, the cause can be one thing, or a combination of things going wrong. Predicting the cause can be a challenge, as PCSX2 is also affected by this issue, albeit at a lesser degree.

'''Performance bottleneck order:'''
<pre>
VU1 ==> EE ==> GS
As can be seen, the biggest bottleneck for the ps4 is the emulated VU1.
Therefore its Speedhacks will be the most effective for performance.
</pre>
====Debugging through PS4CHEATER====
<pre>
The program PS4CHEATER  can be used to debug PS2 register by adding these addresses into it:
1000000368 (Jakv2 uses this offset)
1000000360 (Emus with older revision use this one)
And change the type into > View as Hex.
Make sure live cheats is on.
One of them will contain the Currently executing offset in the ee's memory.

== Description ==
==Description==


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.

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.
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.
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.  
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 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.
While PS3 emulators patch bios to preferred region, emulator used in PS4 uses a so called CallHook which is better known for pcsx2 users as fastboot. No need to describe patch here, just look at PCSX2 fastboot code. It's the same code, but PS4 emus don't have patches for different bios revisions.
