r31253r31254
77    A blend of arcade video game, and pinball.
88
99ToDo (babypac):
10- You can play the video portion but try not to use the lower
11  escape chutes. If you do, alternate between pressing X and
12  right-shift until you are returned to the maze.
1013- No sound
11- No inputs
14- Playfield inputs
1215- Mechanical
1316- Artwork
14- Beeper needs to be replaced by a red LED when artwork gets done.
17- Beeper needs to be replaced by a red LED when artwork is done.
1518
1619ToDo (granny):
1720- All of the above, plus:
r31253r31254
1922- It has 2xTMS9928 but only 1 screen. The outputs need to be
2023  blended with transparency. The '9' test screen will have
2124  coloured stripes overlaid with the text names.
22- The RAM layout is incorrect.
2325- No schematic found.
2426- DIP names are different.
