This release of UnofficialOS fixes some known bugs along with updates to emulators, cores and various packages. PPSSPP stand alone has been brought up to 1.19.2, and is fixed on the AMD64 build. Booting on the R3xS units is fixed (thanks to @EatPrilosec for finding my typo). Device quirks for the clones have been added, along with Drastic controls being fixed. We've added a Device Diagnostic Tool to help us eliminate problems and bugs. It will generate and dump a text file into the roms folder that can be sent to us to help debug things if users have issues. Rclone, SyncThing, TailScale, HTTP Server, Wine, Box64, Moonlight, QT and Systemd have all been bumped as well. Special thanks to @andremedeiros and @stolen for their work on the clones.

IMPORTANT Known Bugs/Issues

Clone Devices With Single Sticks

Right now there are issues with single stick units, we are working to fix this while we wait for our development units to arrive.

Powkiddy RGB20 Pro and Clones

Currently there are no leds working when uOS is running. Charging led works if the unit is powered off. We are working to fix this.

Powkiddy X55

This device has a few known issues.

1. Charge the unit while its turned on, not while its powered off or sleeping.
2. Plugging the power cable in with the unit off causes it to boot. This is normal right now for the unit to charge.
3. Powering down fully for more then a few minutes at a time resets the battery meter. This IS NOT drain, its a bad meter reading.
4. And last, sleeping the unit breaks sound.

What I have been doing currently is charging the unit to 100%, sleeping the unit when not in use, then I'll wake it and reboot when I want to use it. It still has very good battery life when sleeping, as I only lose between 5% and 10% battery daily. Not ideal I know, I'm working towards a fix.

X86_64

This build has some broken emulators, specifically:

1. CEMU
2. XEMU
3. Vita3K

Odroid Go Advance

There is currently hotkey issues with this unit, specifically with PortMaster. Ports require a hard shutdown (not recommended).

Working for fixes on all mentioned issues and bugs. Please report bugs/issues to the uOS discord here.
