Mame is on a network share, and runs fine on other computers, all other games I've tried work fine. It's running windows 7 64bit. It's an dual dual core amd 64 bit server with scsi raid drivers that won't run in xp, so I'm stuck with either windows 2k3, 2k8, or vista premium all of which are just 2 expensive.
Booted vista, same thing, deleted the ini files, saves, tried another version of mame, deleted backgrounds, artwork, same thing. I've tried dozens of other games, they seem fine, tried the same roms and mame.exe on another computer, gyuss looks fine. It's bugging the crap out of me.
