OpenGL FFVII Graphics Driver and WINE

[arew264]

I'm wondering if anyone has tried to run FF7 in Wine (on linux) with Aali's OpenGL graphics driver. If I remember correctly, the main problem with running it was graphics problems, and the custom driver *should* resolve that. The only other OS-specific code that could give Wine problems would be the sound, but I've never heard of that causing problems in Wine, probably because the API is a lot simpler.

Oh wait... Hopefully CD checking won't cause issues, because that could be a showstopper.

Anyway, I'll copy my FFVII installation over to Linux and add the registry keys. I'll report my findings back here. Hopefully this post is in the right forum.

Okay, after fiddling with Timidity (MIDI driver), I can get to the main menu and watch the intro video. The game starts, but crashes in the first battle. I'm going to have to do it again to see if anything is obviously causing the crash.
[EDIT]
Well, the crash just happens a few moments after the battle starts, nothing seems to specifically happen. It could be at the start of one of the enemy soldier's attacks.
[/EDIT]
Wine gives this just after the crash occurs: err:ntdll:RtlpWaitForCriticalSection section 0x7d22f9c0 "x11drv_main.c: X11DRV_CritSection" wait timed out in thread 0018, blocked by 0009, retrying (60 sec)

Loading my current save game (which is in Cosmo Canyon) gives an instant crash.

What bothers me is that the crash dumps are blank, and an emergency save file is never created, even if I say yes at the prompt.

Aali, if you're reading this, when the renderer needs to play a video, does it just get a filename or something along those lines, or is the linkage more direct? If it's loose, would it be possible to try and load the file with the extension changed to mkv, and fall back to avi if such a file can't be found? I hate the current audio quality, and it seems to me that a good solution would be to repack the video with flac audio in a matroska, which is supported by ffmpeg.

[EDIT]
Well, the audio does have more problems than the quality that bugs me. It bugs me on Windows too, so that's not a Linux thing, but in Wine, sounds are clipped at the front and end, seemingly randomly, such that if I switch between "Continue" and "New Game" at the main menu, the sound I get varies from the full chirp to a short squeak to a small pop.
[/EDIT]

Anyway, I'm still fiddling at this point. Kudos to Aali, the graphics are flawless, including the battle swirl, except that the credits effect before the main menu where the words fly from different sides and converge runs really really fast. Is that symptomatic of anything involving the renderer? The only scenario where I can see that happening is if Wine is responding incorrectly to calls to gettimeofday and its cousins, but that would mess up more than this effect.
Oh, and the MIDI kind of falters every so often, and it bothers me that it can't keep a steady tempo. That's a problem with Wine/Timidity though, and I'll worry about it later. Right now, MIDI works, and that's good enough.

Okay, on to the debugging. Is there a way to make FFVII output more verbose? I doubt it, but I haven't had to do this before.

I'm not sure what's with those COULD NOT READ/WRITE FROM/TO FILE *.P. Aren't those files created at the root ff7 directory? I'll see if there's anything wrong there. Crash file is still blank, and emergency save isn't created.

[arew264]

Eventually I'll stop posting after myself, but it seems like the most logical thing to do right now.

This time, when I started the game, the crash didn't occur until the first soldier was halfway through his attack, and the machine gun sound was played and everything, so the only thing I can think of that might be causing the crash is camera movement, if only because the camera doesn't move before the crash. Then again, I also didn't pick an attack before the crash, so the camera might still be locked in place. Anyway, I don't see what's happening there. Anything I should investigate?

As to the file errors, I deleted all the existing *.P files and made sure the game had write permissions, and it recreated the files at next run, but the errors are still there. It's not a case-sensitivity issue or anything, so I don't see what's going on there either.

I'm seeing if Wine has any good ways of figuring out what's crashing.

[EDIT]
Gah, winedbg (the Wine debugger for applications run within Wine) is crashing and starting itself to debug itself and crashing again and again and so on. It's probably because I'm running 32 bit Wine on 64 bit Linux. I'll switch to a 32 bit linux installation and see if anything changes.

Isn't Linux all binary code...?

[arew264]

Isn't Linux all binary code...?

Not sure what you mean. My installation of linux has all applications, libraries, and kernel compiled for a 64 bit processor, but Wine doesn't work when compiled as 64 bit (I don't remember exactly why), so I have Wine compiled for a 32 bit processor, and I have a number of libraries compiled for a 32 bit processor so Wine can run. However, this sort of setup means that many things that Wine expects to do simply can't be done because a 32 bit application cannot load and use 64 bit libraries.

If you're referring to this whole setup, Wine is a linux application that can parse and run Windows binaries. Windows has a binary format slightly different from Linux, so such a layer is needed. Wine also provides equivalents for many Windows dll's like DirectX and the Windows kernel, essentially recreating the Windows API. It forms a compatibility layer to run Windows applications, essentially translating Windows API calls into calls to Linux API calls.

[BrokenCrowe (Mendelevium)]

I thought linux wasn't user friendly and somewhat old fashioned... where you had to type in the commands?

[Aali]

Don't worry about it, this is on my todo list.

I know about the crash but I haven't figured out what's going on yet. I did not experience any of the other issues you had except for the slurry of errors about the .P files, which should be harmless.

[arew264]

Linux is whatever you make out of it. You can get the equivalent of a DOS prompt and run your system from there (as is done on many servers), or you can run a full desktop environment like KDE or Gnome and have 3d accelerated OpenGL graphics for gaming (or many variations in between). There are games made for Linux as well as Windows like Enemy Territory Quake Wars and other Quake derivatives, and there's the Wine project to let you run pure Windows games like Battlefield xx42 and Crysis on linux.
Linux is a full operating system that's every bit as capable as Windows. Yes, it isn't as user friendly, but it also isn't a black box.

Aali: which part of this is on your todo list?

[Aali]

Aali: which part of this is on your todo list?

Wine compatibility.

[arew264]

Ah, that's good to know. I'm about to fire it up in winedbg on my 32 bit laptop.

[Aali]

Well you wont have much luck, I'm pretty sure the problem is due to windows XP giving special treatment to ff7.exe (rename it and a similar crash occurs on windows)

I'm looking through the ACT database for a fix.

[arew264]

I'm hoping that i can get the API call that's crashing. It's possible that there isn't one, though, and (I hate to sound like a noob here), I assume FF7 doesn't have debugging symbols included? That would make it too easy.

[Aali]

It doesn't, and the crash can happen inside *or* outside an API call, there's nothing wrong with the API function, the parameters are simply incorrect.

[arew264]

I dunno, I'm just hoping to get a clue. Sometimes that works, sometimes it doesn't.

[Aali]

So, it turns out FF7 has a few compatibility fixes, one of them a special "compatibility patch" made just for FF7. Any windows gurus who knows where you can find out anything about those, get in touch with me.

In the meantime, I'm going to make a memory dump of FF7 to see if XP is patching anything at load time.

:EDIT:

While I could not figure out what that special FF7 patch does, the good old EmulateWriteFile shim fixes the crashing problem. I will be implementing a fix for it in the driver.
