| 39 | 39 | * A few of the games have an extra 18K pull-up resistor on the |
| 40 | 40 | blue color gun, Carnival, for example. |
| 41 | 41 | Colors inaccurate? Blue background? |
| 42 | | * Does Digger run too fast compared to the real machine? |
| 43 | | The timing is implemented according to the schematics, but |
| 44 | | who knows... |
| 45 | 42 | * DIP switches need verifying in most of the games |
| 46 | 43 | * DIP switch locations need to be added to some |
