HW seems the natural evolution of Dark Mist type.
TODO:
- T5182 hookup, controls sound and coin inputs. With current hookup it accepts coins but not fully, and sound isn't working at all ...
- Still various unused bits.
- Video registers needs better understanding.
- Nuke legacy video code and re-do it by using tilemap system.
- sprites are ahead of 1/2 frames;
- Writes at 0xb800-0xbfff at attract mode gameplay demo transition?
