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.
Arch R ships 43 pre-generated MIPI panel overlays covering all known R36S display variants, named after the exact motherboard revision (e.g. `R36S-V21_2024-12-18_2551.dtbo`, `G80CA-MB_V1.3-20251212_Panel_8.dtbo`). Panel selection is done by copying the correct `.dtbo` file to `overlays/mipi-panel.dtbo` on the boot partition. Sources live under `config/archr-dts/{original,clone,soysauce}/<MB-revision>/`; the build extracts the panel description from each revision's `rk3326-r36s-linux.dtb` via `config/mipi-generator/generator.sh`.

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.
