Not really debug anymore, just polishing stuff. You can open a serial terminal at 115200 baud on the USB programming jack to “talk” with the game. I’m beefing up what this can do, both for human-readable debugging, and using Bluetooth UART via a tablet or smartphone app.

•  Improved command parser for serial.
• On serial terminal, added commands for servo control, SFX and music (see below)
• Added one-shot switch status return, so tablet app can control rate at which it monitors switch data.
• Improved main game titles, added vendor logos.
• Improved attract mode PRESS START graphic (always thought it looked crappy before)
