PS3 Compatibility List - PS2 on PS3

Jak and Dexter softlock can be next if possible but i think is more easy games has graphical glitches can be fixe than games have softlockups but one game DRIVER 3 is unfixable i think
and would be nice if we (the community ) make repositories of fixes for people get then if want fixes their games of ps2 in PS3 60gb Europeans
 
Jak & Daxter Precursors' Legacy and Crash Twinsanity PAL gxemu fixes in attachment. Credits for original netemu patches to mrjaredbeta (Crash Twinsanity) and Agrippa (Jak & Daxter).

EDIT: Is there a page with those custom configs for ps2_gxemu or they float around this topic only?

-thanks a lot that's very impressive this kind of fixes will help the GXEMU be the best way for ps2 games in my opinion
with rsx 40nm on ps3 60gb pal or 80gb USA CECHE will be the best way

for me I don't any problem put the fixes here in this topic is ps2 compatibility list the goal is the same increase the compatibility of ps2 games on ps3 with netemu or GXemu now

I'm trying to port the SLUS_213.76 configuration, what am I doing wrong?

Due to reversed endianess, 64 bit opcode pairs end up in very weird form.
Original code from game:
Code: 
BC 03 F1 4A 60 04 00 4B
Think of it as of a single 64 bit value, not 2x 32 bit. Now byte reverse it as a whole 64 bits.
Code: 
4B 00 04 60 4A F1 03 BC

This is very confusing because original opcode from 0037EB14 is presented as second opcode, while that one from 0037EB18 is first. The same rules apply to replace opcodes.

other game freezes softlockup is WRC the first one but I think exist one config for netemu for the japanese version
Tekken Tag slow motion ( but i think is uncorrectable ) is the same with netemu
Black teleport or freeze i don't remember well

Greetings!

Both PAL and NTSC versions of Ecco the Dolphin: Defender of the Future have a noticeable graphical glitch in one of in-game cutscenes - a relatively minor one, but maybe it wouldn't be too difficult to fix with a custom CONFIG?

The issue in question can be seen in this video (not mine and recorded on PCSX2, which behaves exactly the same) starting from 5:35:39, it looks like cyan flashes:


I don't know if this info would be of any help for PS3's emulator, but on PCSX2 it's actually fixable (for latest stable and older nightlies) by enabling FPU Negative Div Hack or (for latest nightlies) by switching either EE Rounding Mode to "Nearest" or Division Rounding Mode to "Negative" or "Chop/Zero".

P.S. Just in case: there exists a level select cheat for this game, it can be found at GameFAQs, plus I can provide savestates for PCSX2, if needed (though, I don't have ability to post links just yet).

Okay, I hope I won't be cluttering this thread too much, just wanted to share my own findings regarding that bug with Ecco's cutscene I mentioned before.

That's for PAL version. For NTSC it's 0x2CB518-0x2CB7BC, but I mostly do my testings on the former, because it's the one I usually have at hand and because it supports 60Hz anyways. Speaking of which, the glitch is apparently capable of being MUCH worse in the 50Hz mode, like visuals turning into a mess of colored rectangles rather than just flashes of blue light.

So far I've come up with two ways of dealing with the issue, sadly neither of them is ideal:

1. Use the 0x0F command (actually just 0x27 is enough, 0x26 doesn't seem to affect anything) on the range above: reduces those flashes significantly - if you're lucky you won't see a single one, but it's random and sometimes it would still flicker for me during tests once or twice.

2. NOP the last instruction using 0x0A command and skip that section altogether: this gets rid of flashes completely, but will break a visual effect that's used in at least one another cutscene (can be seen in the video in my previous post at 5:53:07, looks like glowing purple spheres) making it almost invisible.

Well, considering that the game already has tons of smaller glitches (mostly texture flickering, nothing as severe as that flashing) caused by calcualtion inaccuracies, perhaps the first option isn't too bad…

Maybe something better could be achieved with commands 0x11 or 0x12, but I haven't had much time to take a closer look at them yet; I'm planning to, eventually, though they sure look a bit intimidating for a total noob like me. :D

That's for PAL version. For NTSC it's 0x2CB518-0x2CB7BC, but I mostly do my testings on the former, because it's the one I usually have at hand and because it supports 60Hz anyways. Speaking of which, the glitch is apparently capable of being MUCH worse in the 50Hz mode, like visuals turning into a mess of colored rectangles rather than just flashes of blue light.

So far I've come up with two ways of dealing with the issue, sadly neither of them is ideal:

1. Use the 0x0F command (actually just 0x27 is enough, 0x26 doesn't seem to affect anything) on the range above: reduces those flashes significantly - if you're lucky you won't see a single one, but it's random and sometimes it would still flicker for me during tests once or twice.

2. NOP the last instruction using 0x0A command and skip that section altogether: this gets rid of flashes completely, but will break a visual effect that's used in at least one another cutscene (can be seen in the video in my previous post at 5:53:07, looks like glowing purple spheres) making it almost invisible.

Well, considering that the game already has tons of smaller glitches (mostly texture flickering, nothing as severe as that flashing) caused by calcualtion inaccuracies, perhaps the first option isn't too bad…

Maybe something better could be achieved with commands 0x11 or 0x12, but I haven't had much time to take a closer look at them yet; I'm planning to, eventually, though they sure look a bit intimidating for a total noob like me. :D

Nice find! Try to additionally use command 0x10 for the same range as it deals with mul/div instruction accuracy. If that does not improve anything, you can also use command 0x0E on the specific add/sub instructions to see if that makes any difference. Making entire functions accurate can sometimes negatively impact them, so it can be finicky dealing with them. Hopefully one of these can fix the issue completely.
 
Can you guys fix Harry Potter 2 (CechC08) Pal60gb? There are some glitching textures when you are in the castle for example, when you are far away they appear black when you are near everything's ok, there's also times when you open a door and the character just walks &walks and then goes through textures (but there are ways to get through that) as far as i remember there were no such things in the netemu - the config fixes that game on it

Oh, I apologize, it looks like I forgot to add that part to my post! Actually, I already tried using 0x10, but admittedly just that alone, without 0x0F. It didn't seem to do anything on its own, and the reason I stopped experimenting with it was because it unfortunately turns the game into a slideshow whenever that part of the code runs (e.g. not just during that cutscene, but also whenever you activate a generator, and probably for some other events).

I'll try using 0x0E, but I suppose it can't be used for VADD/VSUB instructions? I suspected the VMUL instructions specifically being the culprit here, because I remember my first strategy still mostly working if I shortened my range to include just all of the VADD/VSUB instructions that command 0x27 apparently works with. Basically, that's also why I thought that maybe I should try looking into some other VU0-related commands next, but I might be totally wrong with my understanding of these things, of course.

And yeah, definitely have to be careful, because during my test some of my attempts would even break an important NPC's AI: at best he would just position himself awkwardly, but at worst he would get stuck, essentially softlocking the game, as he's needed to finish the level, lol.
 
Can you take a look at this attempt to port the netemu config to gx_emu?

Skips check due to inaccurate math and allows player to climb dumpster in level 2.

All credits to kozarovv for finding this. This is untested on PS3, but works fine on PCSX2.

Definitely try both 0x26 and 0x10 as PCSX2's div hack is pretty much command 0x10. It may be slow, but we can at least see if it is fully working or not.

Otherwise, feel free to post your memory card and we can take a look at it!

Yeah, it's weird, 0x26 + 0x10 doesn't seem to do much, aside from making the game run at about 3 FPS: the flashing is just as bad as without config, unless I also add either 0x27 or use 0x0F + 0x10 instead, but in that case it just works almost the same with 0x27 alone, i.e. makes flashes less prominent, but doesn't get rid of them completely.
In fact, because the game runs so much slower with 0x10 active, those flashes become even more noticeable than with a config with nothing more than 0x27 (such one usually looks almost comletely fixed).
Does PCSX2's div hack affect VU0 operations as well? Psdev wiki says that one of the modes for 0x12 is essentially 0x10, but for VU0 opcodes, so maybe that could help? I would try, but I'm not yet sure how to use that complex command properly…

Here's the memcard with all levels unlocked that I use with PCSX2, and I also included two savestates for both PAL and NTSC versions there:
https://gofile.io/d/6m3pYz
The level with that broken cutscene is called "Powers of Levitation". Unfortunately, the game doesn't allow saving mid-level, and the cutscene in question triggers at the very end, meaning that it's required to play the whole level from start to finish to see it. If you're not familiar with the game, the video I linked earlier should show how to beat it, but doing this every time sure gets annoying even when you know what to do. (

Thank you so much for trying to help me!
