Oli-Boo-Chu Oli-Boo-Chu (aka Punching Kid)
driver by Nicola Salmoria driver by Nicola Salmoria
TODO: TODO:
- main->sound cpu communication is completely wrong, commands don't play the - verify CPU speed/XTAL, currently guessed
intended sound. - verify AY8910 irq freq and XTAL, both are approximated from video recording
- Figure out (ad)pcm format or chip? see samples roms, 16.1m is definitely death sound.
Sample triggers are already hooked up preliminary.
- How is the first half of the palette used? (the colors, not the clut).
The title logo looks better with it, but not much else does. Or maybe it's a
region change? The Japanese Irem flyer (Punching Kid) shows the purple/yellow
maze colors. The USA licensed version has a black background like in MAME,
and it matches a video of the cabinet.
