If you’re having a problem uploading a new game to your Arduboy, you may be encountering a bootloader issue. Some games use so much memory that your Arduboy’s bootloader cannot correctly enter into the mode needed to reprogram. Luckily, the Arduboy has a built-in function to prevent this from stopping you from installing another game. It’s called flashlight mode.
To use flashlight mode to install another game:
- Turn off your Arduboy.
- Hold UP on the D-Pad.
- While still holding the D-Pad, turn on your Arduboy. You should see your Arduboy’s LED’s light up white.
- Release the UP button.
- Connect your Arduboy via USB and attempt to transfer the game, again.
