Dual 68k + 2xZ80
no other hardware info..but it doesn't seem related to taitoair.c at all
TODO:
- Fix "sprite" emulation, it's probably a blitter/buffer with commands etc.;
- Comms between the four CPUs;
- understand how to display the "dots", my guess is that they are at 0x200000-0x203fff of the sub cpu (this might need a side-by-side);
- Fix "sound cpu error" msg;
- Inputs, particularly needed for a game like this one;
