Hey,
I agree whammoed...
I've recently been researching various video cards for my MAME cab (thank you for your help BTW) and have noticed several posts regarding triple buffering problems with the 9200-based AVGA card. It's a brand new chip so I guess there may be a few glitches along the way...you're very right though, I suspect Andy will be very diligent in checking these problems out and resolving them ASAP if they turn out to be related to the recent chip switch.
