TODO:

- The watchdog test prints "WATCHDOG TEST ER". Just by looking at the code, I can't see how it could print anything else, there is only one path it can take. Should the game reset?


NOTES:

- Zoar: At location 0xD50A is what looks like an undocumented opcode. I tried implementing it given what opcode 0x23 should do, but it still didn't work in demo mode. So this could be another protection or a bad ROM read. I'm NOPing it out for now.


VIDEO HARDWARE NOTES:

- Burger Time doesn't have a color PROM. It uses RAM to dynamically create the palette. The palette RAM is connected to the RGB output.
