OpenTracker v2.2.3-ot1

The first OpenTracker fork release for the original Polyend Tracker, built on upstream 2.2.3. Stock projects still load and play; fork data lives in side files that stock firmware ignores.

Install:

1. Back up your SD card.
2. Copy PolyendTrackerOTv223.ptf to /Firmware. Keep the name: the bootloader only accepts 24-character names.
3. Go to Config > Firmware update and select it.
4. Keep the stock PolyendTracker_1.9.2.ptf in /Firmware so you can go back.
