Regs
- 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).

Misc info
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.
- Settings ignored by emulator (there is more than that): https://pastebin.com/Hm9bfnF6
- Settings which use bool (0/1, emu accept true/false on/off too) as value: https://pastebin.com/iaLLAXHn
- Settings which use double float as value: https://pastebin.com/cZvxCb6K (unk max values are likely DBL_MAX )
- Default VU1 settings used by Jak TPL emu: https://pastebin.com/tDsTNWFH
- Default VU0 settings used by Jak TPL emu: https://pastebin.com/iSEngpJh
- Default VU settings used by Jak TPL emu: https://pastebin.com/NL8Vae1b
- Default IOP settings used by Jak TPL emu: https://pastebin.com/9K4dk6vb
- Default FPU settings used by Jak TPL emu: https://pastebin.com/YrF7fBT5
- Default EE settings used by Jak TPL emu: https://pastebin.com/SBXimZhc (awesome formatting pastebin, good job)
- Default COP2 settings used by Jak TPL emu: https://pastebin.com/aG0LDryy
- Default misc settings used by Jak TPL emu: https://pastebin.com/79JCRXkq (ps2_lang is changed later if host system match possible ps2 languages)
Misc misc info
- 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.
Few popular misunderstandings
- 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.
--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.
addiu $sp, -0x30 sd $s0, 0x20+saved_s0($sp) move $s0, $a0 sd $s1, 0x20+saved_s1($sp) li $s1, 0x81E0 dsll32 $s1, 15 dsra32 $a0, $s0, 0 sd $ra, 0x20+saved_ra($sp) jal litodp nop move $a1, $s1 jal dpmul move $a0, $v0 move $a1, $s1 jal dpmul move $a0, $v0 move $s1, $v0 lui $v0, 0xFFFF dsrl32 $v0, 0 and $s0, $v0 dsll32 $s0, 0 dsra32 $s0, 0 jal litodp move $a0, $s0 bgez $s0, loc_2F3734 move $a0, $s1 li $a1, 0x83E0 dsll32 $a1, 15 jal dpadd move $a0, $v0 move $a0, $s1 jal dpadd move $a1, $v0 ld $ra, 0x20+saved_ra($sp) ld $s1, 0x20+saved_s1($sp) 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
"Injections" are special sets of precompiled functions, idea is known better as HLE emulation. Available injections can vary depend on ps2-compiler.self, because that's where lookup for available functions is done. This literally replace code that normally is 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

Please keep in mind that names can be misleading because if function can be reused for EU release, then US inject is used. This happen in Max Payne2 injects.

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" !
Fast Accurate MUL Implementation
While Accurate MUL is implemented as very resource heavy fully fledged soft float operation, there is theoretically less accurate but very fast "accurate MUL" available. Surprisingly this is not copy pasted PS3 implementation (no need to reach Olympus from Lop Nor this time). While this implementation is assumed to be less accurate (than soft floats), result should be the same as with soft floats. r14 and esi are source floats for operation. So, here it comes:
mov edx, r14d mov eax, esi xor eax, r14d shr edx, 23 and eax, 80000000h and edx, 0FFh jz mul_end ; mul by denormal mov ecx, 817h bextr ecx, esi, ecx ; esi >> 23 & 0xFF jz mul_end ; mul by denormal and r14d, 7FFFFFh and esi, 7FFFFFh add edx, ecx or r14d, 800000h or esi, 800000h imul rsi, r14 shr rsi, 23 vcvtsi2ss xmm0, xmm0, rsi vaddss xmm0, xmm0, cs:(float)0.5 vmovd ecx, xmm0 shr ecx, 23 lea edx, [rcx+rdx-115h] cmp edx, 0FFh jle case1 mov ecx, 7F800000h mov esi, 7FFFFFh jmp case2 case1: add ecx, -150 xor ebx, ebx shr esi, cl mov ecx, edx and esi, 0FF7FFFFFh shl ecx, 23 test edx, edx cmovle esi, ebx cmovle ecx, ebx case2: or esi, eax or esi, ecx mov eax, esi mul_end: ret
RESEARCH TO DO
| Name | Notes |
|---|---|
| Locating the gs registers | Abysmal. |
| Trying to reverse-engineer any emulator's executable by using assembly and hxd to improve compatibility | Tedious. / TPC register's instruction 8998B0030000 |
| Locating the proper CDVD read speed (God of war and Ratchet size matters [Both have affected music]) | IOP and CDVD commands help |
| Fully understand what the vif chunk command thingy does | Too low and your game will freeze at the intro |
| Find out what some of the gs commands do and edit their description | Infelicitous! |
| Understand the gs lua functions | |
| Implement a EE memory patch for ratchet up your arsenal | Not trivial obviously |
- GS registers aren't mapped in easy way comparing to other ones. Offsets will vary per emulator, and that's for sure. This is what you get in read mode on JAK emu (not sure if i have v1 or v2 to be honest, 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 issue tho). --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. --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)
Config table with IDs from Jak emu
Table from Jak emulator, this is how emulator config parser see data from cli. Please don't edit typos, etc. This is how it is in emulator. I'm leaving it here, so main page can be slowly updated with data from table if needed. Emulator translate commands to ID, then use ID in jump table in parser to apply cfg. ID is not guaranteed to be the same between emulators, but i didn't tested that. Comments match id too. Script for ida to dump this info will be posted soon. UNK value is not critical for anything, but it is used for something, and it is part of original table. This table is missing few commands which are parsed outside of main cfg routine.

Script
IDA Script to dump this info, should find all by itself. Should... Tested on jak emu, and rogue emu. Keep in mind that it will dump only to ida output window, to dump it to file you need to modify it by yourself. Script will separate fields by comma. Output will be ID, UNK, COMMMAND, COMMENT. Next commas are eventually from config comment itself.

It seems modifying the eboot.bin of any emulator using HXD allows using 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'm not sure when and if to work on it. --Scalerize (talk) 19:10, 29 June 2024 (CEST)
