Emulator

Have you tried to disable the dual core enable option?

Have you tried without using savestates since those are really buggy?

I have tried without dual core. Still the same.
I have tried without savestates, too (not so extensively obviously because I need to wait longer for the bug to appear). Still bugs.

Little precision : when the bug (or bugS) occur(s), there is not necessarily something special on screen (I mean, no heavy particle effects, no lag, no nothing) or no special sound effects (voices or stuff). It is just during gameplay. Happens in window and fullscreen mode.

Would you please identify the revision where this issue started? Start from 3.0-483 to the latest.

Interesting, I never see this game.

OK, I will try to look for the revision, even though I suspect it was a bug hidden in the previous revisions that became visible because some other part of the emulator became faster, so there is a race condition or something like that.

If you tell me in which source file the code causing the error could be located, I might have a look at it. I am a developper, but I never worked on an emulator.

I cannot guarantee that I will test the revisions fast because I have a LOT of work to do, so see you in a few weeks.

By the way, when the game crashes, most of the time, I do not get an error code (just freezes with sound looping). But when there is one, then I get a ton of them in a row.

Have a look in Fifo.cpp and CommandProcessor.cpp, but we can't be sure which area is causing this issue as you said that single core mode does not help.

Only post one revision where this game is working, is enought for me. Batalian Wars 2 porgramming sucks, so maybe the first sucks too.
In the pastt the gfx problems are produced because of fifo reset or CPREad cpRW pointers writed for the games.

Thanks.

No problem. I finally found the time to test the revisions. Here are the results for the 3.0- versions:
374 OK
590 OK
673 OK (sometimes freezes for about 1 sec but recovers)
680 bugged
683 bugged
But maybe I didn't play long enough on 673 version since the thing is random.

I wish it will be of some help for you guys.

decfabr...@voila.fr, please, can you give me some sort of save not a savestate which is closes to the issue point

Thanks, I will ask for a friend who has this game for test :) I need some days.

Like Autoran1@yandex.ru said, if you have a savestate, please attach this.

Yes i think i've found one freeze spot in the first mission, but i have no GFX FIFO messages

Sometimes, there is no error message.
I will try to give you a save (may take some time because I don't have my gaming machine with me), but you can also take my savestate from the first post, return to the main menu and save, this will create you a clean (memory card) save.
By the way, just complete the first mission (5 minutes) and you will be able to start the (buggy) second mission from a fresh save.

Here's your save

decfabrice, would you please retry this with the latest 3.5-393 revision? I was unable to reproduce this one.

I just managed to finish mission 2 on the first try, so I guess the issue is solved (version 3.5 - 367). There are now sound problems, but this is another issue. Thanks guys for the good work on the emu.
