OK. Thanks for the info.
So, when buying a cab, what's the ideal monitor? How will I know if I'm getting a multi-sync or a straight 15hz?
And from your description, even with a 15hz monitor, I can still manage games in 640x480 but I guess I'd never be able to hook up an X-Box or 360 because of the video output? (Which kind of explains why so many projects I read about replace the arcade monitor with TVs.)
