PS2 Emulation

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 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.

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.

Diagnosing problems

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 by the Scene.

EE

Emulators

Every emulator is programmed in a different way, Sometimes Choosing the right emulator is the only possible way to fix a game, this list includes The typical usage of some of The emulators.

Emulator	Usage	API Version	Similar emulators (Compatibility)
Jakv2	Good compatibility with most ps2 games, and it has a very high api version which means more LUA commands are supported.	2.2?
RECVX	Fixes Games like Jackie chan Adventures, Pac-man World 3, Yu-Gi-Oh: Capsule monsters Refusing to boot since the emulated Program counter (pc) register is much more accurate in this emulator than others which reduces TLB miss frequency		Fatal Fury
Forbidden siren v2	The only emulator that fixed Ice age 2 being stuck at splash screen. this emu possibly has EE cache support
GTA3	Fixed the pal Version of Genji: Dawn of the Samurai
KOF2000	fixes graphical issues in games such as Crash Twinsanity, And prevents Koei tecmo games from suddenly freezing when battle starts, since it emulates VU1/VU0 very accurately		Roguev1 and KOF98
Parappa V1	The only emulator that was able to Boot Spyro: A Hero's Tail

Accurate PS2 Settings

Accurate emulation settings for debugging Ps2 Games, very slow.
Do note that this is not a universal CLI, But it will work well for most games.

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.

Example configs

Official example

require( "ee-gpr-alias" ) -- you can access EE GPR by alias (gpr.a0 / gpr["a0"])
apiRequest(0.4)

-- Star Wars: Racer Revenge (SLES-50366) [US]

local eeObj		= getEEObject()

eeInsnReplace(0x13d7f0, 0x1000ffff, 0x0804f45d)	-- retry FREAD() for fix #9025,
eeInsnReplace(0x13BCD0, 0x3c023f80, 0x3C023F40) -- Zoom

-- Track#
-- The Grand Reefs 			: 6 
-- Ruins of Carnuss Gorgull : 9 
eeObj.AddHook(0x187330,	0x3c010001, function()
				 local track = eeObj.GetGpr(gpr.a1)
				 print(string.format("Track : %d", track))

					eeObj.Vu1MpgCycles(1000)	-- makes it be 30fps.
				 else
					eeObj.Vu1MpgCycles(100)		-- default value.
				 end
end)

Custom config.lua example

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

And here's an example for a pnach that was converted into a lua

apiRequest(0.1)
local eeObj = getEEObject()
eeObj.ReplaceMem32(0x0016A7B2,0x0)

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.

Config repository: https://github.com/Zarh/ManaGunZ/tree/master/pkgfiles/USRDIR/sys/CONFIG Just download as raw file, and rename correctly.

Please keep in mind that not all commands are recognized, only 0x01 (can depend on emu revision), 0x09, 0x0A, 0x0B, 0x0F, 0x10, 0x26, 0x27, 0x42. For example Rayman 3 config Does not work due to unsupported command.
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 Ps2 emulator

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	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 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.	ee hook AdvanceClock or fastforwardclock commands on affected addresses, Most of the time it will be CTC2 instructions that are affected	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/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
XGKick in-accuracy	Def Jam Vendetta, Galactic Wrestling, Crash twinsanity, and others	Cli command --vu-xgkick-delay
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. [2]	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 double layer disc games	Shadowman, Arctic thunder, every game that's listed to require CDVD_READ_DELAY in the bios patches. and many other affected games	Setting --cdvd-sector-seek-cycles=0.1 at a very low value for faster Disc reading	Also known in sony's bios as CDVD_READ_DELAY
(Theory) The emulated EE is overclocked by default	Ratchet and clank games, Metal gear solid 3, Syphon Filter: The Omega Strain, SOCOM II: U.S. Navy SEALs, Soul Calibur 3, Need for Speed: Underground, Others	None, although setting eecyclescalar above 1.0 might slightly help since it skips cycles and you can never go wrong with using fatal fury's emu for this issue	These games are extremely EE sensitive. once you overclock the EE, those games will have issues. PCSX2 fixed that with EETIMINGHACK just in case the user overclocks the EE. but on this emulator there's no way to underclock the EE. in fact, it seems that the EE is overclocked above +3 by default for some reason. and it also could possibly be the reason why the VU0 unit is not running in sync with the EE. it seems also that the Fatal fury emu is slightly less overclocked than other emus. the games that needed the ee to be overclocked in pcsx2 no longer need to be overclocked in this emulator. and the games that encounter issues when the ee is overclocked are broken in this emulator. and that alone is proof that the EE is most definitely overclocked by default.
Clamping is turned off by default for FPU and VU units	Every game that requires clamping, Klonoa, Digimon Rumble arena 2, Bully, Devil Kings, Batman - Rise of Sin Tzu, others	the cli commands --fpu-no-clamping=0 --vu1-no-clamping=0 --vu0-no-clamping=0 --cop2-no-clamping=0
In-accurate VU 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, 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
TLB in-accuracy (TLB Miss)	Jackie chan adventures, Pac-man world 3, Spyro enter the dragonfly, Yu-Gi-Oh Capsule monsters, others	Using Recvx emu or Fatal fury emu	More explanation on this issue but basically this issue could lead to games freezing at the splash screen. OpenPs2loader uses what it calls "Mode 2" to fix this issue, though the frequency of this issue on ps4 is different than Pcsx2 and OPL

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)

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.

PS20220WD20050620.crack file MD5: 83AD2B530C9C102A561BA1CDC6D996D5

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.
