TODO:
- colour decoding might not be perfect
- Background color should be green, but current handling might be wrong.
- some unknown sprite attributes
- don't know what to do when the jackpot is displayed (missing controls ?)
- according to the board pic, there should be one more 4-switches dip
  switch bank, and probably some NVRAM because there's a battery.
