According to someone at Wells-Gardner, the specs are:
Horizontal sync is 15.7khz
Vertical sync is 60hz
Resolution is 400 X 240
Two things concern me. 1) I still don't know an appropriate value for PCLOCK. 2) (This is going to sound stupid) Is 400x240 the maximum resolution that I'm going to be able to get?
I don't understand why I can get a stable 640x480 in vbev and advv, but when ArcadeOS tries it, the screen jumps everywhere.
I've also tried AdvanceMenu, hoping that since the games were displaying, the menu would display as well. No luck. I either get dumped out to DOS with an error, a split screens, or total garbage
depending on whether vbe is loaded, and the device_video option.
