  Emulation by Bryan McPhail, mish@tendril.co.uk

  Trivia ;)  The Mad Gear pcb has an unused pad on the board for an i8751
microcontroller.

TODO:
- The seem to be minor priority issues in Mad Gear, but the game might just
  be like that. The priority PROM is missing.
- visible area might be wrong
