TODO:
- EEPROM hook-up;
- sound interface;
- implement remaining video features;
- inputs are bare bones and needs extra work, they doesn't work on attract mode?
- printer device;
- camera device;
- sound interface, needs full Neo-Geo conversion;
- inputs are bare bones and needs extra work;
- printer/camera devices;
- lamps;
- upd4990a returns 4 years less than expected?
