Arch R is a custom Linux distribution for the **R36S** handheld gaming console and all its variants, built on top of [ROCKNIX](https://github.com/ROCKNIX/distribution) with an **Arch Linux-based** build environment. It supports **16 board profiles** and **20 display panels** across original and clone hardware.
- MIPI panel overlays for every known motherboard revision, generated on demand by the online overlay generator at https://arch-r.io/overlay-generator/ (or during flashing by the Arch R Flasher).
Panel overlays are not baked into the images. Generate the overlay for your exact motherboard revision at the online generator, https://arch-r.io/overlay-generator/ (pick your board, or upload the stock `dtb` from the SD card that shipped with the device), then copy the resulting file to `overlays/mipi-panel.dtbo` on the boot partition. The Arch R Flasher can also generate and install the overlay during flashing. The `/flash/overlays/` folder on a fresh install contains a `README.txt` with the same instructions.

Special thanks to:
- **[ROCKNIX](https://github.com/ROCKNIX/distribution)** -- the upstream distribution that Arch R is forked from. ROCKNIX provided the complete build system, device support, EmulationStation integration, and the foundation for handheld gaming on Linux.
- **[JELOS](https://github.com/JustEnoughLinuxOS/distribution/)** -- the project that ROCKNIX was originally forked from.
- **[CoreELEC](https://coreelec.org/)** and **[LibreELEC](https://libreelec.tv/)** -- the embedded Linux distributions whose build system forms the backbone of this project.
- **[Hardkernel](https://www.hardkernel.com/)** -- for the Odroid Go Advance BSP U-Boot and kernel device trees.
- **[Rockchip](https://www.rock-chips.com/)** -- for the RK3326 SoC and rkbin firmware.
- **[Mesa](https://mesa3d.org/)** -- for the Panfrost open-source GPU driver.
- **[RetroArch](https://www.retroarch.com/)** and **[Libretro](https://www.libretro.com/)** -- for the emulation framework and cores.
- **[EmulationStation](https://emulationstation.org/)** -- for the frontend.
- All developers and contributors across the open-source community who made this possible.
