It MAMECE-10X crashes when I try to run Gauntlet after disabling the 6502 :(

Well, I haven't yet found a way to get it to run w/o the 6502, I tried 1/2 normal clock speeds and it hung, and the video hardware is too complicated for me to understand, much less improve. So it looks dim for Gauntlet right now.
