Getting started
From the project's README ("Status and safety"):
- Verified in the native simulator, the browser build, and the JieLi chip emulator.
- Runs on a real FM-1 (first install 2026-10-29, tag v1.0-hw): the screen, all 27 keys, pressure, the CPU meter, saving and the USB Sounds and backup tools all work. The installed package was built from this tag with fm1-base 086cd0c (sha256 1a3b809f…7fc5).
- No firmware package (.fwsc) is included in this repo.
- Before installing any custom firmware:
- back up the unit's full flash;
- keep the official V15 image for recovery;
- have the RP2040 "Transporter" recovery dongle ready.
