OPN-1 2.0.1 runs on newer FM-1s.
Use it with the web app: https://opn-1.putch.co.uk/ (Chrome or Edge).
What's changed since 2.0.0
- Newer FM-1s carry a different flash chip, the UC25HQ80, instead of the Puya P25Q80. On those units 2.0.0 kept the library and settings in memory only, so they were lost at power-off. 2.0.1 accepts both chips, in the app, the USB rescue and the update loader.
Nothing else changes: on an FM-1 with the original chip, 2.0.1 behaves as 2.0.0.
Install

To go back to 1.0 or the official firmware, install that instead, or use the FM-1 Firmware Hub.
