driver by Angelo Salese, based off info from Noca$h
TODO:
- EEPROM defaults / fix EEPROM hook-up, all games but F-Zero doesn't
boot at current stage
- Fix sound CPU halt / reset lines, particularly needed by this to work
correctly;
- Various M50458 bits
- OSD should actually super-impose with the SNES video somehow;
Notes:
- Multi-Cart BIOS works only with F-Zero, Super Tennis and Super Mario
World;
