== Description ==
 
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.
 
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.
PlayStation 2 emulation on PS4 is handled slightly differently comparing to PS3. Each PS2 game PS4 package file (.pkg) include emulator itself, so there is no included emulator in PS4 firmware. This slightly complicating providing compatibility list as emulators include some per title patches, and default settings. Currently most used emulators came from Rogue Galaxy, and Jak games. Next difference is that BIOS in external file is included in .pkg, anyway it is exactly the same BIOS used in ps2_netemu. Another important difference is the lack of encryption mechanism for PS2 game disc image file: this time it is just a plain ISO file. Memory card is also decrypted, but emulator check crc of some of it regions to ensure that fresh card is not modified. PS2 Emulator supports LUA scripting by "Lua Bridge", is powerful interface that provide many possibilities to improve compatibility.
This is first time when sony need care about floats in their emulator. This is resolved by clamping, and/or converting floats to double precision. Emulator use openCL for GS, and probably other components.


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.
== Emulator Configuration ==


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.
=== Files ===


= Emulator Configuration =
Emulator configuration is probably handled by 4 files:
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.

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

=== XXXX-YYYYY_cli.conf commands ===
Please note that commands listed here work also in config-emu-ps4.txt. Anyway official way to use them is by CLI file. CLI file way is also needed for multi-disc packages.


<pre>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.</pre>

<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>

====[https://www.psdevwiki.com/ps2/Graphics_Synthesizer GS]====
==== XXXX-YYYYY_config.lua ====
<pre>"GS" stands for Graphics Synthesizer. It's the PlayStation®2's co-processor that's responsible for rendering the graphics (but is also used by some games for additional calculations and other purposes)</pre>
 
It is most powerful config. Allow direct patching EE/IOP/VU memory, hooks registers, hook dma. 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. Temporary can have doubled entries, please leave them here, they are not really doubled.

=== 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.

| 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.'''

|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'''

=== XXXX-YYYYY_config.lua ===
 
<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.
<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").
<br>'''Known functions:

This is a very basic command to replace a part of the EE memory with another instruction.
| SLPS_256.98 || Fatal Fury Battle Archives Volume 2 || 00000000 0000000A ||
* 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.

* 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

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).

Updated only on branch/jump tests, unless commands such as --ee-pc-coherency  or --ee-insn-flush-pc are used.<br>
| SLPM_624.37 || Suisui Sweet: Amai Ai no Mitsukekata || 0B000000 00000040 ||  
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

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

This register most of times will hold last executed syscall address,
| SLPM_622.39 || Supercar Street Challenge || 0A000000 00030800 ||  
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.
| SLPM_621.54 || DDRMAX Dance Dance Revolution 6thMix || 08000000 5E1A0000 ||  
Thus meaning it's better at diagnosing problems.</pre>

In this part, we describe the PS4 native Floating point support and OpenCL information, for both CPU and GPU. The understanding of floating point conversion is very important for emulating the PS2. The information below came from this [https://gist.github.com/masterzorag/06cadbc5fbe7d3375704fc52518f434e#file-gistfile1-md gist].
