TODO:
- needs merging with ikki.cpp
- look up schematics for all games
- banbam and pettanp likely share the same MCU code, check once redumped
- MB8841 data might be good! same hash as arabian, unsure if dumped twice
or just copied from arabian. hookup looks to be very(?) different compared
to arabian though
- fix banbam/pettanp simulated comms or hopefully hook up MCU ports and
at least get something out of the existing dump
