I know I've had it about three days, but the video on the nova sucks. Anyone ever open one? I'm this close from ordering a JROK and scrapping what is inside. I have no idea what kind of circuitry MAS uses, but it sure seems old. I can barely see the screen with my ehrgeiz board. It works excellent with the capcom stuff, it seems tuned for it.
Then I'd personally sell the MAS and build something with a JROK. I take it you're using S-Video, then? Try getting an RGB monitor (even one of those old Amiga ones - the Philips was great). That should give you a better picture.
