- verify AY8910 irq freq and XTAL, both are approximated from video recording
|

- verify CPU speed/XTAL, currently guessed, but it's logical to share the same

master XTAL with AY8910
|

- verify adpcm freq/prescaler
|

- HC55516 should actually be HC55536
|

- verify HC55536 clock, I don't think it's from master XTAL, maybe R/C osc

- is the "Chu has food" sample ever played? Nothing is written to soundcmd when

a Chu eats a Boo dropping
|

- 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.
