- This is a driver for a gambling board with a yet unknown name.
- The PCB is labeled with: WU- MARY-1A
- And there's a text string in the ROM that says: "Music by: SunKiss Chen"

- Driver by Felipe Sanches

- TODO:
- * Figure out where exactly all devices are mapped to (the devices are
- 2 sound chips, the 2kb SRAM, the 8bit dipswitches,
- 31 LEDs, 13 modules of double-digit 7-seg displays and 4 push-buttons).
- * we may also have user inputs from the coin slot and from the
- cabinet buttons, for making bets.
