I'm modelling resolution for galdrvr.c driver. This is bit tricky because horizontal should be 768 why vertical only 224 (I've calculated 240 because my TV won't handle 224 correctly) and with 60,606061 Hz. I've calculated following modeline:
Horizontal
Active: 768
Total: 1052
Start: 862
End: 957
Vertical
Active: 240
Total: 261
Start: 242
End: 245
Pixel clock: 1052 x 261 x 60,606061 = 16,6407
is this modeline should work on TV? I've tested similiar resolution taken from web but but upon starting Super Cobra my TV started emiting some high pitch so I stopped test and didn't try again, probably won't hurt my TV but who knows.
My TV is Sony 29'' flat CRT.
Is there any other way to run these games on old resolution 256x224 (256x240)? Is it possible to move it to galaxold.c or use graphics stretching without and tearing or visible signs resizing?
EDIT. ok, I've menaged to run those games as desired (in window 320x240) in cabmame. Still no success in official mame.
