This is an input button for the game Rhythm Doctor to provide you addition immersiveness.

You will need a rapseberry pi pico and an MX switch. Soldering required.

Look up GP2024-CE for detail of how to use this firmware on the Pico. Since we only use one button and the game support controller input, all you need to do is dragging and dropping the firmware, soldering GPIO6 and GND to the switch, and it is ready to go.
