| 7 | 7 | TODO: |
| 8 | | - EEPROM defaults / fix EEPROM hook-up, all games but F-Zero doesn't |
| 9 | | boot at current stage |
| 10 | 8 | - Fix sound CPU halt / reset lines, particularly needed by this to work |
| 11 | 9 | correctly; |
| 12 | 10 | - Various M50458 bits |
| 13 | 11 | - OSD should actually super-impose with the SNES video somehow; |
| 14 | 12 | |
| 13 | Notes: |
| 14 | - Multi-Cart BIOS works only with F-Zero, Super Tennis and Super Mario |
