no other hardware info..but it doesn't seem related to taitoair.c at all
TODO:
- pal banking;
- Sound is nowhere near to be perfect, mode 5 causes "sound cpu error" for whatever reason;
- Palette banking;
- Comms between the five CPUs;
- Gameplay looks stiff;
- Needs a custom artwork for the cloche status;
- Sound is nowhere near to be perfect;
- Current dump is weird, a mix between German, English, and Japanese?
- clean-ups!
