Description
PlayStation 2 emulation on the PlayStaion 4 is handled with little difference to the PlayStation 3, But still many issues that the PlayStation 3 faced have moved into the PlayStation 4 along with many new issues.
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 since all emulation is done on the cpu, 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.
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.
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.
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.
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.
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.
Emulator Configuration
Files
Emulator configuration is handled by 4 files:
- 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.
- disc-swap-cli.conf - Stores info of multi disc games.
Commands
Known functions: Require cleanup.
The rest of the cli and lua commands can all be found inside of an emu's decrypted eboot.bin.

XXXX-YYYYY_cli.conf commands
Please note that commands listed here also work in config-emu-ps4.txt. But the official way to use them is by CLI file. The CLI file way is also needed for multi-disc packages, Some of the Commands are still not discovered, And some known commands are missing some of their values Due to them being not Discovered. The scene has named "CLI" with 3 names, including TXT, CLI, CONF. all 3 are the exact same thing.
All CLI commands are pre-made by sony, We sadly cannot create CLI commands out of thin air. The values of the commands are also pre-defined by sony and /or have a quota for possible values/ranges. Some CLI commands have no effect, and were added into the eboot.bin without being programmed by sony. and some useful commands were removed/added from different emu revisions. or their effects were changed.
CLI commands use SCE modules to change default emulator settings. for instance --cdvd-sector-seek-cycles is actually sceCdStSeek, but is still unclear how to use SCE modules in a lua
EE
Commands for the emulated Emotion Engine. these commands may assist you in gaining performance or better sync.
| Command | Values | Notes | Usage |
|---|---|---|---|
| Speedhacks | |||
| --ee-cycle-scalar | [Overclocking] (0.99 => 0.1) [Underclocking] (1.1 => 5.0) |
If set Higher than 1.0 the Emotion engine Begins skipping cycles, you might face Problems in FMVs if you skip too many cycles. but you will gain a better performance |
--ee-cycle-scalar=1.0 |
| --ee-context-switch-cycles | [Overclocking(?)] (0.99 => 0.1) [Cycle skipping(?)] (1.1 => ∞ ) |
It's still unknown what this command controls, but the higher it is, the more EE cycles are skipped, Doesn't work for jak emulators. |
--ee-context-switch-cycles=2700? |
| --ee-hook | AdvanceClock FastForwardClock Mfifodrain |
Hook a function to a EE offset. it can be used either as a speedhack or to improve sync, FastForwardClock seems to overclock ee at the specified offset, AdvanceClock will do the opposite, FastForwardClock does not need a value to be set, AdvanceClock does. |
--ee-hook=0x0028A7B0,AdvanceClock,,500 Example for usage: --ee-hook=offset,function,optional opcode,value for advanceclock only |
| Game fixes | |||
| --ee-jit-pagefault-threshold | 0-254 | Reduces the occurrence of crashes the higher it is, only accepts 1 byte values with 254 being the limit | --ee-jit-pagefault-threshold=40 |

--vif1-ignore-cmd-ints=1 |
| --vif1-instant-xfer | 1 = Instant transfers 0 = Delayed transfers |
Allows you to change VIF1 timing, 1 is the default one, but 0 is much more correct and recommended, can be used to fix graphical glitches or to prevent the game from freezing when set to 0. |
--vif1-instant-xfer=0 |
GS
GS stands for Graphics Synthesizer PlayStation®2 co-processor responsible for rendering the graphics (but is also used by some games for additional calculations and other purposes) The gs settings are rarely useful since the all rendering is done by software rather than hardware, meaning there will be much less graphical glitches than PCSX2's Hardware renderer, but sometimes autoflush and upscaling fixes will be necessary.

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=40000 |
| --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 [2]. |

IOP
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
| Command | Values | Notes | Usage |
|---|---|---|---|
| Game fixes | |||
| --iop-cycle-scalar | [Overclocking] (0.99 => 0.1) [Underclocking] (1.1 => 5.0) |
Not a Speedhack, when you lower it below 1.0 the iop is overclocked, when you increase it above 1.0 the iop is underclocked. the only thing you will notice from this is faster/slower loading speed | --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 in games such as the godfather or gran turismo 4 to solve stuttering fmvs due to very fast iop cycles | --iop-tight-slice-count=12 |

SIF
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 |

Emulators
Every emulator is programmed in a different way, sometimes choosing the right emulator is the only possible way to fix a game, emulators are not provided pre-installed on your ps4, they have to be unpacked from your ps2classics backup that's downloaded from the ps store from that specific game. this list includes The typical usage of some of The emulators. and by emulator we mean the fpkg's Eboot.bin
| Emulator | Usage | API Version | Similar emulators (Usage) |
|---|---|---|---|
| 2017 | |||
Jak v2 |
Good compatibility with most ps2 games, and it has a very high api version which means more LUA commands are supported. | 2.2 | JakX, Jak 2, Jak 3, Parappa. |
AOFA |
Works similarly to RECVX, It managed to fix Coraline | ||
RECVX |
Fixes Games like Jackie chan Adventures, Pac-man World 3, Yu-Gi-Oh: Capsule monsters freezing at the splash screen Most likely due to the way it emulates Vector unit 1 | 1.7 | Fatal Fury, Redfaction, AOFA. |
| 2016 | |||
Redfaction |
It is a very good emulator to use for games that are sensitive to VU1, it was used to fix Tony hawk games suddenly crashing, probably has something similar vu1roundmode 0. | 1.6 | Max payne |
Forbidden siren |
The only emulator that fixed Ice age 2 being stuck at splash screen using kozarovv's patch, it also fixed Gran turismo 4 running EXTREMELY slow, this emu possibly has EE cache support | 0.1 | |
KOF2000 |
Fixes graphical issues and sps in games such as Crash Twinsanity, and prevents Koei tecmo games from suddenly freezing when battle starts, since it emulates COP2/VU1/VU0 timing much more accurately than other emulators | 1.2 | Roguev1 and KOF98 |
rise of the kasai |
Fixed most of the Harry potter games, it also possibly has a good ipu emulation though not yet confirmed | Also referred to as rotk | |
| 2015 | |||
War of the monsters v1 |
Probably the most GS accurate emulator we have on the PS4, Fixed Enter the Matrix crashing with upscaling on, and fixed Devil may cry 2 characters having missing faces, fixed Tekken 5 having graphical corruptions in some levels, Fixed the bard's tale crashing, it also happens to be the default emulator for PS2ClassicsGUI | 0.1 | |
GTA 3 |
Fixed the pal Version of Genji: Dawn of the Samurai, Could be the most GIF accurate emu we have. | ||
Parappa |
The only emulator that was able to Boot Spyro: A Hero's Tail | ||
Star wars racer revenge |
Seems to be the most similar emulator to the ps3. useful for debugging games as it also shows useful information such as pagefault | 0.1 |
All you have to do to make these emulators work for your game is to replace your Fpkg backup's iso with that game's iso
XXXX-YYYYY_config.lua
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. 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
The most important part of a lua. without it the lua will crash the game.
| Command | Usage | Notes |
|---|---|---|

Custom config.lua examples
Here is the first custom lua config created by the community:
apiRequest(0.1) -- Fix black screen SLUS-20064 eeInsnReplace(0x1CF3CC, 0x4100ffff, 0x00000000) -- bc0f 0x1CF3CC to nop
This is very basic command to replace part of EE memory with other 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

PS3 Config support
Emulator support configs in format known from ps2_netemu/ps2classic from PS3. This feature was
officially used in Arc the Lad Twilight of the Spirits ps2-ps4 classic.
To enable ps3 style config add this to config-emu-ps4.txt:
--lopnor-config=1
--ps2-title-id=TITLE-ID
Config file need to be in folder ...'''/patches/{TITLE-ID}/''' and file need to have name '''{TITLE-ID}_lopnor.cfgbin'''. title id need to be in XXXX-YYYYY format (ex. SLUS-12345).
Example path: /patches/SLUS-12345/SLUS-12345_lopnor.cfgbin
Tester confirmed that configs work like that. We don't even need to edit them, they work as is.
Please keep in mind that not all commands are recognized, only 0x01 (can depend upon emu revision), 0x09, 0x0A, 0x0B, 0x0F, 0x10, 0x26, 0x27, 0x42. For example Rayman 3 config Does not work due to the command being unsupported Command 0x07 is NOT recognized, but can be manually translated to cli config (to: --vu-xgkick-delay=value). Same goes for 0x11 (--vu0-accurate-addsub-range can be used).

Known issues
List of known issues in the PS4's PS2 emulator
| Issue | Games affected | Solution | Description |
|---|---|---|---|
Unknown iop issue |
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 | |
Unknown GIF issues |
Tenchu - Fatal Shadows, Genji dawn of the samurai, Harry potter and the prisoner of azkaban, Batman begins, Lara Croft Tomb Raider - The Angel of Darkness, Dragon ball z budokai tenkaichi 1, Possibly many more! |
LUA patches | Includes issues with GIFIFO And Gif_chcr |
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 |
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. |
VU0/COP2 is not running in sync with EE core |
24 The Game, ATV Quad Power Racing 2, Twisted Metal Head-On, Primal, Ghosthunter, Rayman Arena, Rayman 3, Largo winch. All games using M-bit.other games affected by COP2 timing |
ee hook AdvanceClock or fastforwardclock commands on affected addresses, Most of the time it will be CTC2 instructions that are affected Or using Kozraovv's method of EE memory patching |
Rayman 3's fix for example
This issue can also be replicated on Pcsx2 if you overclock the EE by +3 |
No roundmode support for VU or FPU |
Koun, Tony hawk games, Devil may cry 3, Gun, TY the Tasmanian Tiger 3, Beyond Good & Evil, MTX Mototrax, Many others |
Lua patches to the EE memory |
|
No M-Bit support |
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.[3] |
Lua patches to the EE memory |
M-bit: Only applicable for VU0. Ends interlock on a single QMTC2.I/CTC2.I instruction, allowing the EE to continue execution |
Wrong read speed for some games |
Shadowman(Textures), God of war (Music), Ratchet and clank size matters (Music), every game that's listed to require CDVD_READ_DELAY.and many other affected games |
Try your luck with IOP and CDVD CLI commands. | Also known in sony's bios as CDVD_READ_DELAY |
In-accurate VU0/VU1/COP2 emulation |
Sly cooper games, Crash twinsanity, Crazy frog racer, Rayman 3, Koei tecmo games, Klonoa 2, others. |
Choosing a VU accurate emulator such as Roguev1 or Kof2000 with the right clamping commands |
The issue leads to SPS and graphical issues and sometimes freezing. |
In-accurate Multiply/Divide/Add/Subtract instructions |
Max payne, Bully, Jackie chan adventures, Wild arms 3, Pac-man World 3, Gran turismo 4, Others |
Addsub/Muldiv Cli commands |
Causes many geometry issues and black screens. Sony reduced the accuracy of these instructions to improve performance |
Multitap doesn't support all games |
Urban reign, many others |
None | |
DMA writes when busy signal is engaged |
Ratchet and clank games, Metal gear solid 2, others | None yet | AKA eetiminghack |
VU1 running too fast (DMA sync) |
Harry Potter the Chamber of secrets, Mercenaries 2 | None yet | |
VIF1 runs instantly |
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 |
Inaccuracies in the IPU |
Burnout 3, Onimusha dawn of dreams | None yet |
Diagnosing problems
This guide will assist you in tracing the issue's cause,The list is based on what you can possibly solve using CLI
also don't forget to Check out ps3 Emulator Bugs, since many of them also exist in the ps4
| Issue | VU1 | EE | GS | VIF | IOP | COP2 | VU0 | VU | FPU | SIF |
|---|---|---|---|---|---|---|---|---|---|---|
| Performance | ✔ | ✔ | ✔ | ? | ||||||
| Crashes | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | |
| Broken graphics | ✔ | ✔ | ✔ | ✔ | ✔ | ✔ | ||||
| Glitches | ✔ | ✔ | ✔ | ✔ | ✔ |
Performance bottleneck order:
VU1 ==> EE ==> GS As you can see, the biggest bottleneck for the ps4 is the emulated VU1, therefore it's speedhacks will be the most effective for performance.
Debugging through PS4CHEATER
You can also use for instance the program PS4CHEATER and add the addresses of 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 show the Current (Program counter) which will lead you to find out which EE offset the game gets stuck on! or offsets that get repeated/cause performance problems
Faqs

Option(?) | Int = Integer (?) jr = Jump register | cmd = Command ad = Address (?) | XXXX-YYYYY = The ps2 game's region code inst = Instant (?) | PC = Program counter Scalar = A multiplier for the default value | Hook = Attach a function to an offset r59 = EE | ∞ = No limit for possible values (Int32) r30 = IOP | SPS = Spiky polygon syndrome (Another type of graphical glitches) ===============================================================================================================================
CLI
Making a comment inside the CLI
1.You can make a comment inside a cli by using a Hashtag (#) at the start of the comment Example: #Speedup --vu1-mpg-cycles=1000 2.Your comments will be fully ignored if they are in the same line as the hashtag Example: #This is a comment Incorrect example: #This is a comment This is not a part of the comment and will crash the emu 3. hyphens are the start of a command in CLI (--) And as for the equals, (=) everything that comes after it is the value that the command will use On a lua hyphens (--) mean it is a comment, but on the cli it's the start of the command. 4. Commands cannot contain spaces Example: --ee-cycle-scalar=0.1 Incorrect example: --ee cycle scalar = 0.1
Making a CLI.
1. You can use any text editor to make a CLI 2. Each command has to be below the previous one and they cannot share the same line.

LUA
Making a lua
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 iopObj.ReadMem32(0x400000) Without first having this in your lua local iopObj = getIOPObject()
Making a comment inside the lua
You can make a comment in a lua by using two hyphens (--) Your comments will be ignored by the lua You can also use --[[ (comment) --]] All text between --[[ and --]] will be ignored by lua
Commands
(Cycle scalars)
Cycle scalar commands are basically a scale between overclock and cycle skip (Underclock), we say that to simplify for anyone making configs, but in the truth it controls cycle speed of that Processor whether it be (IOP) or (SIF) or (EE). Slowing the cycles can be done by setting it higher than 1.0 (Underclock) (Cycle skip) Speeding up the cycles can be done by setting it anything lower than 1.0 (Overclock) So, it's basically a multiplier of the Processor's cycle speed in a way that's connected to the Delta counter. Sony uses all of them to improve sync, It's recommended to use them for sync also considering that using them can possibly cause stuttering or input lag with no real benefit. Except for eecyclescalar. as using it can be very helpful for performance gain when you slow down the cycles (Anything higher than 1.0). Some games like (Metal gear solid 3) want a very fast EE cycle speed, and will refuse to work if it's at the Default speed. (0.1) is the highest number for overclocking And (1.0) is the Default clock value. And (5.0) is the highest value for Underclocking (Cycle skipping) For the (IOP) and (EE) As for the (SIF) it has no limit for underclocking.
(vu1/0 mpg cycles)
This command sets the cycle speed of vu1 or vu0. 0.1 is the fastest cycle speed and the most compatible (Slowest in terms of performance). 100 is the default value set by sony 1000 is the recommended value for performance gain but you can increase it to any value you like.

PS2 Bios
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.
Bios is know to blacklist some titles, and refuse to boot them. This include all titles with 00000000 000000A0 flag from that list (click here)
More about the bios
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.
