PS3 Compatibility List - PS2 on PS3

Works great :) Thank you so much kozarovv and thanks for your efforts. Could you make a fix for Yakuza? :)

Not tried with Yakuza yet, but I think that game can be fixed by that method. I will try some problematic games I own this weekend.

Short description what I found.

Config commands: 0x0F, 0x10, 0x26, 0x27 are responsible for handling some instructions accuracy. We can compare it to software mode in PCSX2 (is not the same, but can shed some light). Usage of commands is:

Command --> Start offset of EE memory --> End offset of EE memory.
Selected operations in this memory range will be performed with much better accuracy, but it will cost us performance in most cases.
Command are still not clear for me, and I need to do more tests. But looking at PS4 possible configs that I extracted from eboot.bin those are candidates:

  • fpu-accurate-addsub-range
  • fpu-accurate-muldiv-range
  • cop2-accurate-mul-range
  • cop2-accurate-addsub-range

Now we just need figure out which command in netemu is what.
Testing is pretty easy in most cases, so looking for fixes is not specially time consuming. But later when we find fix we need to get smallest range possible to game stay fixed, but not speed affected.
 
So thats why the second value is always bigger, because are specifying a range, oook :)
In order of complexity (to reach the big goal of understanding all them), that 4 commands was very important, in the talk page in wiki was marked in orange to call attention on them

Ok here is test config that I have for now. Work with SLUS-21386

Code: 
00000000  3D 00 00 00 65 3D 00 00 26 00 00 00 00 50 27 00  =...e=..&....P'.
00000010  00 00 30 00 00 00 00 00                          ..0.....

Current issue: Very noticeable slowdown during walking thru map.
Fix: Choral Castle no longer freeze.
Warning: Config is highly experimental, backup your save first.

@kozarovv So how I can make this config with ManagunZ ??

Shadow Hearts 1 and 2

SH2 (From the new world?) issue is freezing near save point? Or something else? I probably fixed it (testing, but it looks ok). About SH1, I know issue and I try later.

Not sure it can be done internally in managunz, if yes then try "add new command" Select 26 command, then first value 275000, and second value 300000

And just when I said I fixed, it freezed :P Those damn random issues, 10 times ok, one time not.

Yeah these Shadows Hearts 1 and 2 are very tricky :) Same as Yakuza. I did not test the Yakuza with the Tales of the Abyss config yet, but I think I can give it a try today evening.
These games have a freezing issue:
- Yakuza
- Shadow Hearts 1 and 2 (I think one config will fix both of them)
- Summoner 2
- Dragon Quest 5
Tales of Legendia has graphic glitch problem and the legendary Valkyrie Profile 2 has a slow downs + freeze randomly.

@kozarovv : your config for Tales of Abyss is game specific? Or is this config fix the Yakuza freezing problem too and the Dragon Quest 5 issue where the characters stuck?

I see. Is there a chance that you can make a config for Yakuza or Shadow Hearts 1,2 and 3. Every one have a freezing issue.

Yeah I'm gonna try tomorrow some of those games. About SH2, it won't work for me. So this game can't be fixed that way. But that SH part where character stuck temporary and, then can move again should be fixable. Is definitely bad calculation, so accuracy fix should help.

About yakuza, is still not clear what is the issue here, anyway I have save very close to moment where it hang. So I try tomorrow.

Any progress about Yakuza and Shadow Hearts 1 and 3? :)

Sadly every Shadow Hearts title seems to not react to config, or even getting worst with it.

Oh these SH games seems like very complicated :) And what about Yakuza? I think thousands of Yakuza fans would be happy if we can play without problem.

No idea how, but I lost save game for Yakuza. And I have no time to play it now from start. I anyone have save file. Or I can post 4 random configs to test.
 
Can anyone test out the Shin Megami Tensei III: Nocturne Maniax Chronicle Edition English Patch with any of the config files you believe will work with it? I get a black when screen when attempting to play it without any config file. the game ID is supposed to [SLPM-66681] but instead its [SLUS-20911] which is the same as the american release and psn version when i use managunz to check the ID
