PS2 Emulation

Description

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, while introducing 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 emulator itself. The ps4 does not have a native built-in emulator in its firmware, but it does a few PS2 emulator specific features, like the functions sceLncUtilIsPs2Emu, sceShellCoreUtilGetImposeMenuFlagForPs2Emu, sceSystemServiceAddLocalProcessForPs2Emu, and sceSystemServiceShowImposeMenuForPs2Emu.

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 as it is the most compatible one out there. When game crashes are concerned, RECVX is typically used, whereas for VU accuracy it is roguev1.

The PS2 BIOS is included in the game's pkg, the same one used on the ps2_netemu. The lack of encryption mechanism for PS2 game disc image file is also important. 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 decrypted, but the emulator checks the CRC of some of the regions to ensure that the memory card was not modified. This PS2 Emulator also supports LUA scripting by "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

The emulator can be configured through 4 files.

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

The rest of the CLI and LUA commands can all be found inside of any emulator's Eboot.bin file.

In some cases, the emulator can be flawed in how it handles multi-tap when it involves "--mtap2". 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

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)

EE

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	Accelerate EE cycles: (0.99 => 0.1) Decelerate EE cycles: (1.01 => 5.00)	Can benefit core sync or performance (too much deceleration can cause stuttery 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, but likely affect COP0. Does not work on Jak emulators. Default value is 360. Seems to be useful for Bee Movie and Metal Gear Solid 3.	--ee-context-switch-cycles=2700?
--ee-hook	AdvanceClock FastForwardClock Mfifodrain	Runs the specified feature every time a selected EE offset is reached. FastForwardClock stalls the EE for an unknown, non-changeable number of cycles. Unlike AdvanceClock, it does not compensate the EE for the cycles it missed, making it a tool for permanently wasting cycles. AdvanceClock pauses the EE for an allocated number of cycles, pushing DMA channels and other micro-processors ahead of the EE. After the number of cycles is reached, the inverse occurs, meaning it is temporary. It mostly helps fix core sync issues, but can be used as a speedhack. Mfifodrain is still unknown. For more examples	--ee-hook=0x0025A9F2,AdvanceClock,,500 --ee-hook=0x0019F0AD,FastForwardClock

FPU

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.

DMA Channels

VIF

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

	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

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.

Emulators

Every emulator is programmed differently. Sometimes choosing the right emulator is the only way to fix a game. Emulators are not provided pre-installed on the ps4, they have to be unpacked from an official Sony made PS2CLASSICS pkg. 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	The emulator with the closest VU0-EE sync on the PS4; setting eecyclescalar to 5 on this emulator will enable some VU0 sync demanding games to run on the PS4.
	2016
Redfaction	It is prominently used to fix games that are VU1 sensitive. It was used to fix Tony Hawk games suddenly crashing, and to fix MTVU sensitive games such as Star Wars Battlefront II.	1.6	Max payne
Forbidden Siren	The only emulator that was able fix Ice age 2 being stuck at splash screen by using it in conjunction with patches. It also fixed Gran turismo 4 running EXTREMELY slow.	0.1
King of Fighters 2000	Seemingly the emulator with closest VU0-EE sync on the PS4. Fixes graphical issues and sps in games such as Crash Twinsanity, Rayman 3, Crazy Frog Racer, and prevents Koei tecmo games from suddenly freezing when battle starts. 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	Fixed most of the Harry potter games. Often referred to as "rotk"	0.2
	2015
War of the monsters v1	The emulator that's used in PS2CLASSICSGUI, and the best one around for GS/GIF accuracy.	0.1	Rogue v1 and v2, Arc the Lad, Star Wars Jedi Starfighter
GTA 3	Fixed the pal version of Genji: Dawn of the Samurai	0.6
Parappa 2	The only emulator that was able to boot Spyro: A Hero's Tail	0.1
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	0.4

XXXX-YYYYY_config.lua

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" ).
Examples
Known functions: Require cleanup.

ApiRequest

The most important part of the lua. The lua will crash the game if it were 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.

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
SchedulerDelayEvent	eeObj.SchedulerDelayEvent("event", cycles) 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.

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

Registers Map

EE-IOP

This list of registers is yet to be completed. Some registers are incorrectly named or include incorrect offsets. 0x1000000xxx base is not guaranteed in different emu revisions, but layout should be the same regardless.
Assuming base is different (Like on kof2000), simply reduce these offsets by 8 hex values
(IOP, VU0, and VU1 registers' offsets are static in all emulators).

 List was designed for Jak v2

Emulator related regs

"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 Config support

The emulator supports configurations in the format known 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 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

Issue	Games affected	Solution	Description
Inaccurate GIF timing	The Matrix: Path of Neo, Tenchu - Fatal Shadows, Genji dawn of the samurai, Batman begins, Dragon ball z budokai tenkaichi 1, and possibly many more!	LUA patches, or hooking schedulerdelayevent on an affected offset
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). 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.
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).
Wrong disc 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
Inaccurate VU0/VU1/COP2 emulation	Sly cooper games, Crash twinsanity, Crazy frog racer, 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.
Multitap doesn't support all games	Urban reign, 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.
IPU emulation inaccuracy	Burnout 3, Tony Hawk's Underground, Onimusha Dawn of Dreams	?
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

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.
Bios is known to blacklist some titles, and refuse to boot them. This includes all titles with 00000000 000000A0 flag from that list (click here)

More about the bios

The version of the bios seems to be developement v2.20 from the Japanese region (22/01/2007), and is 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 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.

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

Game_ID/DiscID in PS20220WD20050620.crack

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. 

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