Thanks
I *do* have a few other revs of MAME. Shame on me for not trying those first. Jasonbar doesn't even love Jasonbar, it seems...
Here's what I found:
Didn't work right in 63 (with rotary stick hack patch)
Backdrop shows up fine in 82
Backdrop shows up fine in 105 (with processor optimization patch & dial hack patch)
Backdrop missing in 108 (with processor optimization patch)
Backdrop missing in 115 (with processor optimization patch)
Backdrop missing in 115u2 (with processor optimization patch)
So, the backdrop appears to have been broken between 105 & 108, so I'm using 105 for Atari Video Pinball on my cab.
I actually kinda like the game--it has some charm. Sure, there are fancier video pinball games out there, but this game is really neat, at least from a nostalgia/innovation standpoint, if not from a pure gameplay standpoint...
Thanks,
