| 9 | 9 | |
| 10 | 10 | - CPU type uPD7810HG |
| 11 | 11 | - CPU PORTD and PORTF are connected to the Gate Array |
| 12 | | - CPU Analog Port (AN0-AN7) is not emulated (connects to DIPSW2 and |
| 13 | | some other things). |
| 14 | 12 | - processing gets stuck in a loop, and never gets to scan the |
| 15 | 13 | input buttons and switches. |
| 16 | 14 | - CPU disassembly doesn't seem to indicate conditional JR or RET. |
