<pre> I have added vu1's regs, all i did was copy vu0's info and replace 0x10300 with 0x10400 in notepad++, so i'd love it if you could rename regs if they are wrong or make sure that the info i have added is correct --Scalerize </pre>

Some data that eventually need to be posted on main emulation page. All data posted here is obtained from jak tpl (so called v1) emulator. All data is confirmed in code itself, no guessing (unless said otherwise). Time to start releasing that old work to public.

==Few popular misunderstandings==
== ee-native-function ==
*vu-xgkick-delay take integer between 0-31 (confirmed on both emu and compiler side), and not float (0.5 is invalid, will be truncated to 0 probably)
*Cop2 rounding in pcsx2 is governed by "EE/FPU" rounding setting, not by VU or VU0.
*Cop2 clamping is hardcodded in pcsx2 as far as i know, if no then is likely also governed by EE/FPU setting not VU/VU0
*xx-no-clamping setting is not really no clamping known from pcsx2. This is special mode which can be used regardless of other clamp commands. To compare pcsx2 have similar mode only for FPU (Full), to fully mimic that mode we still need fpu-to-double enabled.


==ee-native-function==
Emulator have set of predefined functions used in popular PS2 SDK libraries. Those function are highly optimized to run natively on x64. <br>

'''--ee-native-function=name,address''' under the hood this is hooking selected address, and replace it with jump to predefined function. Functions available in JAK TPL emu:

This is corner case example as floatdidf convert a 64bit signed integer to IEEE double, and PS2 developers generally had no reason to use doubles (fpu/vu are operating on 32 bit floats). But you can see that whole conversion is practically done in 1 opcode, while ps2 take massive function to do this. Other functions are usually less optimized, but still really worth it.

== EE/VU injection ==
"Injections" are special sets of precompiled functions. This idea is known better as "HLE emulation". Available injections can vary depending on ps2-compiler.self, because that is where the lookup for available functions is done. This literally replaces the code that normally is the recompiler, with optimized version when address and hash match. Probably not many games can use this. Good candidates are games that use the same engine as currently released PS2 classics. Many times VU1 programs are reused by the same developer.

'''VU1'''
*Name + offset in JAK TPL compiler
*unk1
*VU1 mpg start address (divided by 8)
*Some kind of hash to ensure that correct part of microprogram gets replaced
*Many other unknown values

Same goes for "kernel" injections, they are also based on ID + Hash + address. Generally all "injections" should be safe to be enabled by configs. There is really small chance for hash/address(and id) collision. Not to be confused with "native" / "native-patch" !

* GS registers are not mapped in easy way comparing to other ones. Offsets will vary per emulator, and that is for sure. This is what you get in read mode on Jak games emulator (not sure if I have v1 or v2 to be honest, but it is known as ps2emu16):

But keep in mind that GS regs can be "duplicated" for different emulation stages. GS is jited too, so it should have kind of pipeline too.
"Implement a EE memory patch for ratchet up your arsenal" Game write data using qmtc2/ctc2 and expect VU0 to still run at this point, which is not always true. Mega high vu0 mpg cycles could potentially push it little further. Patching that will be pain just because Ratchet use code overlays. This mean you need to patch game image with the same patch in more than 20 places. Because what you see in PCSX2 debugger / ps2dis will change depend on stage you play now. That's why PS3, and PCSX2 use dynamic JIT patches (PCSX2 use it for different issues tho). --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 14:20, 27 February 2023 (CET)
== no-clamping ==
Sup. Can i know how no-clamping behavior was tested to confirm that "The default emulator's behavior cannot be set by CLI commands."? Because that doesn't sound right, and emulator explicitly set 0 or 1 on init, which is confirmed in emu code. What can happen, is that other clamping settings were changed during test, and that affected result. But looking at code i don't think there is any possibility that something "in between" exist. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 09:33, 21 June 2023 (CEST)
<br>It is based on a test I did on Sly Cooper 2. If VU1 Clamping was set to 1 or 0, the game crashes. If left empty, game works fine. --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 14:58, 21 June 2023 (CEST)
* Do you remember when game crash? Right after ps2 logo, when going ingame, any specific level, etc. --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 15:32, 21 June 2023 (CEST)
<br>Right after the ps2 logo if I recall correctly --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 16:34, 21 June 2023 (CEST)
* I think there was typo in config you tested. Crash right after PS2 logo is usually caused by unsupported command (emu will print "Unhandled option for this build/platform" and hit UD2 right after). Missing separator, typo, upper case characters, or something else was wrong. I double checked emu code, and it is set or not set (0 or 1). Recompiler parts which use it also test only for 0/1, and setting this command don't affect anything else. I'm going to leave description as is because without PS4 i can't test it by myself, but i'm really sceptical about it. :P --[[User:Kozarovv|Kozarovv]] ([[User talk:Kozarovv|talk]]) 16:46, 21 June 2023 (CEST)
So, after taking some time to think about it, I had remembered that the game would crash right after the first pyramid fmv at the press start screen. But yeah, leave as it is. You have the upper hand in removing/adding anything you like --[[User:Scalerize|Scalerize]] ([[User talk:Scalerize|talk]]) 17:19, 21 June 2023 (CEST)
== Configuration table with IDs from Jak games emulator ==
Here is a table from Jak games emulator. This is how the PS2 emulator config parser sees data from CLI. Please do not edit typos, etc as this is exactly how it is in the emulator. I am leaving it here, so that the main page can be slowly updated with data from the table if needed. The PS2 emulator translates commands to ID, then uses ID in the jump table in its parser to apply configuration. ID is not guaranteed to be the same between emulators, but I have not tested that. Comments match ID too. UNK value is not critical for anything, but it is used for something, and it is part of the original table. This table is missing a few commands which are parsed outside of the main configuration routine.

'''It seems that modifying the eboot.bin of any emulator using HxD allows us to use commands without adding them to the CLI. Potentially, we could locate VU0's jit-sync and modify it to fix many issues, while changing the values of other commands to suit our needs. This is a to-do in the future. Considering it needs a lot of researching, I am not sure when and if to work on it. It is filled with what Stayhye calls "speculation".'''

Registers[edit source]

    • 1040000000 VU1 regs, mapping like on VU0.
    • 1050000000 VU1 micro data memory (1100C000 on real PS2 and PCSX2 debugger) size 0x4000.
    • 1050004000 VU1 micro data memory mirror (1100C000 on real PS2 and PCSX2 debugger) size 0x4000. Likely mirrored 2 more times on 8000 and c000
    • 104000C000 emulator place here VU1 constants used in popular operations. Eatan/eexp constants, masks for clamping, etc. Similar array can be found in PCSX2 (mVU_Globals), Dobiestation (atan_const, etc), Play! (GenerateEATAN, etc.)
    • 1030004000 emulator place here VU0 constants used in popular operations. Like above (vu0 don't have efu so placing there efu constants for eatan/eexp is pointless, but there they are).

Miscellaneous information[edit source]

Some data that eventually need to be posted on main emulation page. All data posted here is obtained from jak tpl (so called v1) emulator. All data is confirmed in code itself, no guessing (unless said otherwise). Time to start releasing that old work to public.

Miscellaneous information 2[edit source]

  • Both settings do the same thing:
--external-hdd-fix
--cdvd-determinism

--ee-kernel-hle
--ee-injection-kernel
  • Setting take unused value:
--ee-cache-breaks-block
No matter which value is used, 1 is set.

ee-native-function[edit source]

Emulator have set of predefined functions used in popular PS2 SDK libraries. Those function are highly optimized to run natively on x64.
--ee-native-function=name,address under the hood this is hooking selected address, and replace it with jump to predefined function. Functions available in JAK TPL emu: 

memset      | fptoui           | ieee754_sinf
memcpy      | fptodp           | ieee754_cosf
strlen      | dptofp           | ieee754_sqrtf
strcmp      | fabs             | asinf
strcasecmp  | fabsf            | acosf
litodp      | ieee754_atan2f   | sinf
dptoli      | ieee754_asinf    | cosf
floatdidf   | ieee754_acosf    | sqrtf

This drastically reduce emitted code size for selected function. Additionally there is no need to recompile that at all, emulator just emit jump to label, and that's all. Additionally emulator advance delta clock to compensate cycles which will be normally took by original function.

Example ee_native_floatdidf 

vcvtsi2sd    xmm0, xmm0, rdi
vmovq        rax, xmm0
retn

This is what real floatdidf looks like originally in ps2 mips, you can imagine that recompiled x64 code will be much longer. Every single instruction will be translated/recompiled separately.

move         $a0, $s1
jal          dpadd

ld           $s0, 0x20+saved_s0($sp)
jr           $ra
addiu        $sp, 0x30

This is corner case example as floatdidf convert a 64bit signed integer to IEEE double, and PS2 developers generally had no reason to use doubles (fpu/vu are operating on 32 bit floats). But you can see that whole conversion is practically done in 1 opcode, while ps2 take massive function to do this. Other functions are usually less optimized, but still really worth it.

EE/VU injection[edit source]

"Injections" are special sets of precompiled functions. This idea is known better as "HLE emulation". Available injections can vary depending on ps2-compiler.self, because that is where the lookup for available functions is done. This literally replaces the code that normally is the recompiler, with optimized version when address and hash match. Probably not many games can use this. Good candidates are games that use the same engine as currently released PS2 classics. Many times VU1 programs are reused by the same developer.
VU1

  • Name + offset in JAK TPL compiler
  • unk1
  • VU1 mpg start address (divided by 8)
  • Some kind of hash to ensure that correct part of microprogram gets replaced
  • Many other unknown values

Same goes for "kernel" injections, they are also based on ID + Hash + address. Generally all "injections" should be safe to be enabled by configs. There is really small chance for hash/address(and id) collision. Not to be confused with "native" / "native-patch" !

RESEARCH TO DO[edit source]

Name Notes
Locating the gs registers Abysmal.
Trying to reverse-engineer any emulator's executable by using assembly and hxd to improve compatibility Tedious.
Locating the proper CDVD read speed (God of war and Ratchet size matters [Both have affected music]) IOP and CDVD commands help
Find out what some of the gs commands do and edit their description Infelicitous!
Understand the gs lua functions
  • GS registers are not mapped in easy way comparing to other ones. Offsets will vary per emulator, and that is for sure. This is what you get in read mode on Jak games emulator (not sure if I have v1 or v2 to be honest, but it is known as ps2emu16):

But keep in mind that GS regs can be "duplicated" for different emulation stages. GS is jited too, so it should have kind of pipeline too. "Implement a EE memory patch for ratchet up your arsenal" Game write data using qmtc2/ctc2 and expect VU0 to still run at this point, which is not always true. Mega high vu0 mpg cycles could potentially push it little further. Patching that will be pain just because Ratchet use code overlays. This mean you need to patch game image with the same patch in more than 20 places. Because what you see in PCSX2 debugger / ps2dis will change depend on stage you play now. That's why PS3, and PCSX2 use dynamic JIT patches (PCSX2 use it for different issues tho). --Kozarovv (talk) 14:20, 27 February 2023 (CET)

no-clamping[edit source]

Sup. Can i know how no-clamping behavior was tested to confirm that "The default emulator's behavior cannot be set by CLI commands."? Because that doesn't sound right, and emulator explicitly set 0 or 1 on init, which is confirmed in emu code. What can happen, is that other clamping settings were changed during test, and that affected result. But looking at code i don't think there is any possibility that something "in between" exist. --Kozarovv (talk) 09:33, 21 June 2023 (CEST)


It is based on a test I did on Sly Cooper 2. If VU1 Clamping was set to 1 or 0, the game crashes. If left empty, game works fine. --Scalerize (talk) 14:58, 21 June 2023 (CEST)

  • Do you remember when game crash? Right after ps2 logo, when going ingame, any specific level, etc. --Kozarovv (talk) 15:32, 21 June 2023 (CEST)


Right after the ps2 logo if I recall correctly --Scalerize (talk) 16:34, 21 June 2023 (CEST)

  • I think there was typo in config you tested. Crash right after PS2 logo is usually caused by unsupported command (emu will print "Unhandled option for this build/platform" and hit UD2 right after). Missing separator, typo, upper case characters, or something else was wrong. I double checked emu code, and it is set or not set (0 or 1). Recompiler parts which use it also test only for 0/1, and setting this command don't affect anything else. I'm going to leave description as is because without PS4 i can't test it by myself, but i'm really sceptical about it. :P --Kozarovv (talk) 16:46, 21 June 2023 (CEST)

So, after taking some time to think about it, I had remembered that the game would crash right after the first pyramid fmv at the press start screen. But yeah, leave as it is. You have the upper hand in removing/adding anything you like --Scalerize (talk) 17:19, 21 June 2023 (CEST)

Configuration table with IDs from Jak games emulator[edit source]

Here is a table from Jak games emulator. This is how the PS2 emulator config parser sees data from CLI. Please do not edit typos, etc as this is exactly how it is in the emulator. I am leaving it here, so that the main page can be slowly updated with data from the table if needed. The PS2 emulator translates commands to ID, then uses ID in the jump table in its parser to apply configuration. ID is not guaranteed to be the same between emulators, but I have not tested that. Comments match ID too. UNK value is not critical for anything, but it is used for something, and it is part of the original table. This table is missing a few commands which are parsed outside of the main configuration routine.

PS2 Emulator Configuration Table Dumper IDA PRO Script[edit source]

IDA Script to dump this information. It should find all by itself. Should... Tested on Jak games emulator, and Rogue Galaxy emulator. Keep in mind that it will dump only to IDA PRO output window. To dump it to file, you need to modify this script by yourself. Script will separate fields by comma. Output will be ID, UNK, COMMMAND, COMMENT. Next commas are eventually from config comment itself.

Fatal Fury Battle Archives Vol. 2 Modding[edit source]

It seems that modifying the eboot.bin of any emulator using HxD allows us to use commands without adding them to the CLI. Potentially, we could locate VU0's jit-sync and modify it to fix many issues, while changing the values of other commands to suit our needs. This is a to-do in the future. Considering it needs a lot of researching, I am not sure when and if to work on it. It is filled with what Stayhye calls "speculation".
