This release of UnofficialOS brings fixed and updated cores and emulators, a bunch of bug fixes, and R36 Ultra support. Be aware that only the v1 Ultra has LED stick support at the moment. Clone users please see the updated directions here. These are important steps for these units, so please review this wiki page. Special thanks to @Pretz for the G350 PR, @KitFox618 and @Sundownersport for the help with testing.

R36 Ultra Bug Fix

I apologize to the users of the Ultra, there was a tiny bug in the current stable that stopped the device switches from showing in EmulationStation, which will break ota updates on this unit. This file can be downloaded and placed in the root on the partition where the boot.ini is, the overlay folder etc. Make sure its placed where the boot.ini, dtb files are and not in the overlays folder. With this file, ota updates will succeed, and the switch can be flipped next update. Thanks, and sorry for the inconvenience. As I don't have a unit to test, I missed this.

IMPORTANT Known Bugs/Issues

Clones Units

Currently some clone units currently have no LEDs working when uOS is running.

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.

Odroid Go Advance

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

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

This release of UnofficialOS brings the usual updated cores and emulators, along with support for the BatleXP G350, and numerous RK3326 bug fixes. PPSSPP had been bumped to 1.19.3, along with CEMU, Hatari, and Hypseus-Singe. Bug fixes include fileman being fixed for clones, updated controls on the R36S units (specific stand alone emulator fixes include Drastic, PPSSPP and Mupen64 mappings), and a V2 .dtb for specific clones with audio issues (please see wiki for instructions). The units that I've seen with this issue are the Batman clones (T16Max, S600, H50Pro), the R36S clone units, and the R36Ultra. There may be more, but these are the units that I'm aware of right now. The BatleXP also has specific instructions that need to be followed (please see here for instructions). Special thanks to @christianhaitian for the G350 dev unit, bsp .dts and joystick driver rotation code.

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.

20250708

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.

This release of UnofficialOS brings a bunch of updates to emulators, cores and packages, along with a new image for RK3326 clone units. There's still some issues we need to work out on devices with single sticks, and we are waiting on dev units now to test. OpenSSH and OpenVPN have been updated, along with ScummVM to 2.9.1 and Mupen64Plus to 2.6.0. All RetroArch cores are up to date as well. Please download the correct image for your supported device. Special thanks goes out to @ROCKNIX, @stolen for the webtool idea and code, and @andremedeiros especially for all his help lately on uOS. Without his help, clone support wouldn't of ever arrived this fast.

Folder Structure for Bios And Games

The folder structure has changed from the root of SD2 to a single folder. The folders for these must now be in a folder named "roms". The folder structure for SD2 can be generated by using the "Create Game Directories" option under System Settings. If you have an existing SD2 with all the folders on the root of the card, just create the folder named "roms", and move the rest of the folders (bios, nes, snes, gb, etc) into this folder. If this is not done ES will not see your games.
