| 7 | 7 | |
| 8 | 8 | Todo: |
| 9 | | everything |
| 10 | | - Finish memory map, fill in details |
| 11 | | - Finish input ports |
| 12 | | - Finish palette code |
| 13 | | - Finish machine driver struct |
| 14 | | - Finish cartslot code |
| 15 | | - Etc, etc, etc. |
| 9 | - Fix cpu and system problems that prevent the games from working. |
| 16 | 10 | |
| 11 | Game Status: |
| 12 | - The DAC sound partially works, sound from ports 1,2,3 not done |
| 13 | - Inbuilt ROM and PDA functions all work |
| 14 | - When starting a cart, the graphic of the cart going into the slot is corrupt |
| 15 | - Due to an irritating message, the NVRAM is commented out in the machine config |
| 16 | - Cart games all have severe video issues such as flickering and nonsense gfx |
| 17 | - Lights Out works |
| 18 | - Centipede works with bad flickering |
| 19 | - Frogger works, but there are bugs on the 2nd row of cars (if you turn your |
| 20 | frog to the right it dies, and also one car goes in reverse), and not possible |
| 21 | to get the female frog. |
| 22 | - Wheel of Fortune 1&2, playable although the spinner is corrupt |
| 23 | - Jeopardy, playable with bad gfx |
| 24 | - Quiz Wiz works, but the final score doesn't show |
| 25 | - Tiger Web Link & Internet, they look ok, obviously aren't going to connect to anything |
| 26 | - Williams Arcade Classics, Robotron works, the rest are no use. |
| 27 | - The remaining carts are not functional to any useful degree. |
