PicoMicroMac UF2 Creator

Builds firmware for use with the PicoMicroMac.

Select any bootable disk image compatible with the 128K, then copy resulting firmware to the Pico.

Without a disk image you get firmware that reads its disk from an SD card.

Flashing

1. Hold the BOOTSEL button on the Pico while you plug it into USB.
2. A drive named RPI-RP2 appears. On a Pico 2 it is named RP2350.
3. Copy the .uf2 file onto that drive. The Pico restarts when the copy finishes.
