I'm trying to get this thing to run on MAME32, and it keeps saying that my 29f400.u2 is corrupt, where the CRC should be 74205250, but I have fb172a8e. The game just crashes after it asks me to press OK several times.

Does anyone know what's wrong here?

Thanks.

use clrmamepro with the latest mame dat from logiqx to check your set.It should fix up all your errors.

Actually when I checked the status in MAME, it says "not working", maybe MAME doesn't work with Street Fighter III?

Actually, I tried in MAME32++ and it says that it's supposed to work according to the game's profile. But it keeps saying that it can't find the u2 file, which folder is it supposed to be in exactly?

The file should be inside of a zipfile called sfiii3 (or similar).
The zipfile belongs in your ROMS folder.

Also, since your file has the incorrect CRC, you should download the latest version from a reputable rom site.

That's a great question. My cousin asked me why he couldn't get it to work and I was completely clueless. Anybody know?

Once it does accept your roms, it will want to set up its NVRAM. This can take an hour, but you only have to do it once.

Unless, of course, you run the non-cd version.

It worked when I tried the sfiii3, turns out that I was using sfiii instead. Forgot about the 3.

When I launched the game the first time, it had an over 20 minute wait time about something rewriting to CDrom, do you know what that is about?

Also, for games like samurai showdownV, there were also some CRC errors, but the game runs fine and I can't detect any errors. So does that mean that those two files that the CRC didn't match doesn't really matter?

That's the NVRAM write at first boot that Robert mentioned earlier. You can speed it up by fast-forwarding. All CPS-3 games do this.

Your going to have to rebuild your romset. My recommendation is to use clrmamepro. It might seem confusing at first but its good to keep your romset current.

@Hera probably missing some files.

By updating you mean to update the rom to the most current version compatible with my version of MAME right?

Don't I have to do that whenever a new version of MAME is released?

That depends whether or not the MAME developers have changed the naming of individual ROM filenames, romsets or have dumped previously undumped or poorly dumped ROMs to existing sets - otherwise, your "old" sets will work just fine on a new version of MAME.

No, this doesn't happen very often, but it does happen.

I only update every stable mame release. I skip over the u versions. For example 130u2 130u3 etc . I will update when it reaches 131 and then again at 132 etc. Its perfectly fine to use older romsets but you should be using the corresponding mame version for better performance. I still use mame 116u3 for cps3 games sometimes but I also have the cps3 116u3 mame set.

But if you have a lot of roms, then you can't do them all right?

Actually, I tried the roms again with MAME32++, and the CRC errors do not exist anymore, I think the plus version solved the problem.

A lot of Roms have the "video emulation isn't 100%accurate, sound emulation isn't 100% accurate", what does that mean? Some roms don't have it.

It means just what it says; if video emulation is not 100% accurate, it means that the games video hardware isn't emulated to match exactly how the real hardware works. This doesn't necessarily mean that you'll see lots of graphics errors - you might not see anything wrong at all, yet the graphics still aren't emulated with 100% accuracy when compared to the original hardware.

It's the same thing with sound emulation.

for emulation of all street fighters 3, the emulator "cps3 emulator v1.0a" works great.
