I'm using MAME32k v0.67, and it works great ^^ however, when I play games like 19xx, I need to play in a windowed screen and not full screen because its just a few thin lines across (kind of like you're trying to put your screen res too high), so I'm figuring thats my problem. Is there any way to get MAME to run the games in different screen resolutions without altering your desktop res?
