Vertical games which need 288 lines of resolution still seem to be a problem though. GM is displaying them at 320p which seems to make it too "squished" and un-centered in the screen. Did you happen to see the mspacman log I posted in the last post?
Yeah, I've confirmed this. The d9200 preset probably needs some tuning. Try changing this value:
monitor "d9200", "Wells Gardner D9200", "4:3"
crt_range0 15250-16500, 40-80, 2.187, 4.688, 6.719, 0.190, 0.191, 1.018, 0, 0, 224, 288, 448, 576
crt_range1 23900-24420, 40-80, 2.910, 3.000, 4.440, 0.451, 0.164, 1.048, 0, 0,
384, 384, 0, 0
crt_range2 31000-32000, 40-80, 0.636, 3.813, 1.906, 0.318, 0.064, 1.048, 0, 0, 480, 512, 0, 0
crt_range3 37000-38000, 40-80, 1.000, 3.200, 2.200, 0.020, 0.106, 0.607, 0, 0, 512, 600, 0, 0
