TODO:

- Video registers meaning: Have a look at subcpu routines $11,$12 (different registers init according flipscreen dsw).

- Sound: Can be guessed from DSW and what main68k does with 'DemoSounds On/Off' subcpu routines $05,$06,$07 + elsewhere (search for $10600c in dasm) status/data register is probably $10600c + 2/6 (hooked up but commented out for now).

- Player controls not really understood - they end up @ $2000b1.b,$2000b5.b, see $21e2a

- 'sub68k IT' is not hooked up (except the one triggered by main68k). NOTE: triggering any IT at VBL makes self-test HANG.



NOTES:

- Turns out to be quite similar to other kaneko16 games (main 68k + mcu), mcu communication triggering is identical to bloodwar & gtmr and except it has a sub 68k that seems to drive a 2nd video chip (and sound)?
