oops sorry about that m8, i use a nvidia geforce4 ti4200 card,
i used mame but after your second post i tried the dosmame, wich runs fine, but now when i load a game the screen is really small

. btw, i dont know if this works but would i be able to play n64 games trough the arcadeos on my arcade monitor?
edit: the screen is perfect now, i can play games, buti have no sound, i tried all seven soundcard modes available in arcadeos but none works.
