A ZVG may just be a bit much for an Omega Race cab. Especially since it's a B&W monitor. I'd mame it, add a few buttons and you could then play Star Trek, Cosmic Chasm and Zektor pretty nicely. Depending upon how many buttons you add and where, Asteroids, Asteroids Deluxe, Gravitar, Space Fury and Space Duel would look very, very cool in that cabinet. Mounting a monitor with the mirror will be a PITA but Omega Race is a very nice cabinet and I think it would be worth it.
