They look AMAZING at 640x480... if you turn antialiasing on... I'm assuming your running an arcadeVGA so you will probably want 640x288 and set anti-aliassing on.
Download it and get it working... will take you 15 minutes... Download one or two tables.
don't mess with the wrappers yet... Just run it once and see if you like it.
but I LOVE it on my cabinet. I added 4 buttons just for it... And I'm still considering building a control panel just for it (that sits on top and rocks back and forth... so the tilts would be really moving it... just pressing tilt buttons)
