Editing 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.

== Commands ==
'''Known functions:''' Require cleanup.
<br>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 ===

<pre>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.</pre>
<pre>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.</pre>
<pre>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</pre>

====SIF====
<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. 
but they could help with fixing many games that are still unplayable due to Syncing issues</pre>

=== Emulators ===
<pre>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.</pre>
{| cellspacing="0" cellpadding="2" border="1" class="wikitable" style="text-align: center;"
! Emulator !! Usage !! API Version !! Similar emulators (Usage)
|-
| <pre>Jak</pre> || 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.'''
|-
| <pre>RECVX</pre> || 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|| || '''Fatal Fury,''' '''Redfaction,''' '''AOFA.'''
|-
| <pre>Forbidden 
siren</pre> || 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 || ||
|-
| <pre>GTA3</pre> || Fixed the pal Version of '''Genji: Dawn of the Samurai''' || ||
|-
| <pre>KOF2000</pre> || 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 || || '''Roguev1''' and '''KOF98'''
|-
| <pre>Parappa</pre> || The only emulator that was able to Boot '''Spyro: A Hero's Tail''' || ||
|-
| <pre>Redfaction</pre> || It is a very good emulator to use for games that are sensitive to MTVU. it was used to fix '''Tony hawk games''' || 1.6 || '''Max payne''' 
|-
| <pre>AOFA</pre> || Works similarly to RECVX, It managed to fix '''Coraline''' || ||
|-
|<pre>War of the monsters v1</pre> || 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, it also happens to be the default emulator for PS2ClassicsGUI ||
|-
| <pre>rise of the kasai</pre> || Fixed most of the '''Harry potter''' games, it also possibly has a good ipu emulation though not yet confirmed|| || Also referred to as rotk
|-
|}

=== XXXX-YYYYY_config.lua ===

<pre>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" ).</pre>

'''Known functions: 
'''
Require cleanup.
====ApiRequest====
<pre>The most important part of a lua. without it the lua will crash the game.</pre>
{| cellspacing="0" cellpadding="2" border="1" class="wikitable" style="text-align: center;"
! 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.

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

<pre>Warning: 0x1000000xxx base is not guaranteed in different emu revisions, but layout should be the same regardless of base.
if base is different (Like on kof2000), simply reduce these offsets by 8 hex values.
This list was made for the purpose of making a future debugger for the PS4's PS2 emulator.

=PS3 Config support=
<pre>
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.
</pre>

<pre>
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).
</pre>

'''Performance bottleneck order:'''
<pre>
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.
</pre>

====Debugging through PS4CHEATER====
<pre>
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

'''This list was made since most of the emulator's Commands and /or Wiki instructions are hard to comprehend for most users.'''
<pre>

===============================================================================================================================
</pre>

==CLI==
'''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


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
</pre>
'''Making a CLI.'''
<pre>
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.

Correct CLI example:
--vu1-mpg-cycles=1000
--ee-cycle-scalar=1.1

Incorrect CLI example:

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

3. Your commands cannot contain spaces
4. Values start after the (=) sign
5. Commands can possibly contain multiple value entries and some values can be skipped by adding (,,).
Example: --ee-hook=0x0028A578,AdvanceClock,,1000

Unskipped value example: --ee-hook=0x0028A578,AdvanceClock,0x13a893bd,1000</pre>

==LUA==
'''Making a lua'''
<pre>
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()
</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.
</pre>

'''(vu1/0 mpg cycles)'''
<pre>
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.
<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.

<pre>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.</pre>
