I did try to run it in the software mode, and had this problem with it.
Ok, sound acceleration is put all the way down now. Did you mean hitting the button next to the hardware acceleration slide bar with '8 bit palletization test'? If so, it just played some jungle sound and asked me if I could hear it, and I did, every time. Although in the end, it said my sound card can't support hardware buffering and sounds will only be played through software buffering.
EDIT: After pulling the slide bar all the way back, it doesn't even load the starting eidos and squaresoft movies any more.
I downloaded the latest Nvidia driver available. Also an omega driver, but the problem occured before using this one, so that can't have anything to do with it (I downloaded the omega driver to be able to switch the screen graphics rapidly).
I think I tried that Riva TNT patch, and read a lot about it as well, but after you mentioning it I can't find it on my pc any more. So maybe I skipped that one. I'll definately check it out. (By the way, wouldn't the ultima edition have this patch as well? If so, I already surely had it in a way when trying that one.)
EDIT: Although the patch seems to be removed from their site; only FF8 can be found. But that's ok, I can likely get it somewhere else. But I have yet to find it.
Yes, the Chocobo patch is already waiting for the complete game to work.
And I noticed the people here weren't too fond of the Anime Vamp

Thanks a LOT for your help, it's very much appreciated.
