by adding chips and wires to the inside of the game.
TODO:
- Need instructions
- Proper SED1503F emulation (it's simulated in-driver for now)
- After each keypress it hits a HALT instruction. I guess the controller
should respond with a pointer to a RET somewhere.
- After each keypress it hits a HALT instruction. I guess the controller's
sync pin is involved somehow.
- When it wants tiles, put 64 into FD1B (monty), 7D1B (mmonty) and press
Enter.
