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,
But still many issues that the Playstation 3 faced Have moved into the Playstation 4 along with Many new issues.


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 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>


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.
<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.
 
 
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.</pre>

Emulator configuration is handled by 4 files:

=====FPU=====
====( 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=====
====( 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, 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.

|ThrottleNorm ||emuObj.ThrottleNorm() || Enable default framelimiter (50/60 fps depend on region).
|  || 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,'''
|ThrottleFast || emuObj.ThrottleFast() || Faster than default, but exact value is unknown.
|-
|-
| Art of Fighting Anthology || Similar to RECVX. It was successful in fixing "'''Coraline'''." Sometimes called "AOFA" || 2.0 ||
|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 ||  
|-
|-
| 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.'''
|OpenDiscTray || ||
|-
|-
| Fatal Fury Battle Archives: Volume 2 || Similarly to RECVX, it is often used to fix frozen games. ||  ||
|CloseDiscTray || ||
|-style="background-color:#D7EF54"

| 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'''
|SwitchDisc || emuObj.SwitchDisc(<disc ID>) || ID can be provided as is, or for example read from memory or register when needed.
|-

| GetDiscId || emuObj.GetDiscId() || Return DiscId in XXXX_YYY.ZZ format
|-
|-
| 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'''

|-
|-style="background-color:#D7EF54"
|  || 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'''
|LoadConfig || ||
|-
|-
| GTA III || Fixed the PAL version of '''Genji: Dawn of the Samurai'''. || 0.6 ||
|SaveConfig || ||

apiRequest(0.1)
 
-- Fix black screen SLUS-20064
 
eeInsnReplace(0x1CF3CC, 0x4100ffff, 0x00000000) -- bc0f 0x1CF3CC to nop
</pre>
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

require( "ee-gpr-alias" ) -- you can access EE GPR by alias (gpr.a0 / gpr["a0"])
apiRequest(0.1)
-- EA sports cricket 07 bug 9392
-- Performance fix
local emuObj = getEmuObject()

==== Custom config.lua examples ====
 
Here is the first custom LUA configuration created by the community:
 
<pre>
apiRequest(0.1)
 
-- Fix black screen SLUS-20064
 
eeInsnReplace(0x1CF3CC, 0x4100ffff, 0x00000000) -- bc0f 0x1CF3CC to nop
</pre>
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

<pre>
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).

| (?) || 0x1000000360      || Locking the value seems to cause a crash.
|-style="background-color:#8b9dc3"
|Current PC<br>(4 Bytes) || 0x1000000368 || Shows the current offset that's being executed by the EE.<br>
Updated only on branch/jump tests, unless commands such as --ee-pc-coherency  or --ee-insn-flush-pc are used.<br>
Then updates are instant, right when instructions are executed. <br>
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  ||<pre>(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)</pre>
|-
|Cycles ||0x1000000378||
|-
| (?) || 0x1000000384 || <pre>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.</pre>

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

For example, the Rayman 3 configuration does not work due to the command being unsupported on PS4.

| <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>
|-
| 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.
|-
| 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).
<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.

'''Making a comment inside the CLI'''
<pre>
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


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 [[PS2_Emulation#Game_ID/DiscID in PS20220WD20050620.crack|here]].
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


'''More about the PS2 BIOS'''
On a lua hyphens (--) mean it is a comment, but on the cli it's the start of the command.
<pre>
4. Commands cannot contain spaces
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.
Example: --ee-cycle-scalar=0.1
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.
Incorrect example: --ee cycle scalar = 0.1
</pre>
</pre>
 
'''Making a CLI.'''
'''PS2 BIOS file information:'''
<pre>
<pre>
File name: PS20220WD20050620.crack
1. You can use any text editor to make a CLI
MD5: 83AD2B530C9C102A561BA1CDC6D996D5
2. Each command has to be below the previous one and they cannot share the same line.
</pre>


== Files inside ROM image ==

--vu1-mpg-cycles=1000
--ee-cycle-scalar=1.1

3. Your commands cannot contain spaces
| ROMDIR || 0x2780 || The ROMDIR part of the ROM image, which provides information on the location and name of files contained in the image. || BIN
4. Values start after the (=) sign

5. Commands can possibly contain multiple value entries and some values can be skipped by adding (,,).

<pre>
|-
When making a lua there is 1 part that is always necessary (Apirequest)
| IOPBTCON2 || 0x1EB10 || Boot configuration file for the IOP, for the first phase of the IOP reset (before UDNL is loaded). || BIN
and 2 parts that are almost always necessary (Object) (Object's commands).
|-
By order it goes like this:
| SYSMEM || 0x1EBE0 || System Memory Manager. || ELF
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()
</pre>
 
'''Making a comment inside the lua'''
<pre>
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
 
 
</pre>
==Commands==
<br>(Cycle scalars)
<pre>
Cycle scalar is 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.

==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>Bios is know to blacklist some titles, and refuse to boot them. This include all titles with 00000000 000000A0 flag from that  [[PS2_Emulation#Game_ID/DiscID in PS20220WD20050620.crack | list (click here)]]
 
<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.
