Steps

  1. 1Pick a community OS that lists the RGB10 Max 3: ROCKNIX is the verified choice, and Batocera ships it via the Anbernic RGxx3 RK3566 image.
  2. 2Download the matching RK3566 image (.img.gz) from the project's releases page.
  3. 3Insert a 16GB+ microSD into your PC and write the image with balenaEtcher.
  4. 4Power off, put the card in the TF1 (OS) slot, and power on to boot the new OS.
  5. 5Use the second microSD (TF2) for your own ROMs and saves.

The RGB10 Max 3 (RK3566) is a community-OS favourite. ROCKNIX has a dedicated install page for it, and Batocera supports it through the shared Anbernic RGxx3 RK3566 image; ArkOS also builds for RK3566, so verify your exact device is listed before flashing. Write the chosen RK3566 image to a microSD with balenaEtcher, boot it from the TF1 slot, and keep games on TF2. These RK3566 ROCKNIX and Batocera images flash cleanly with balenaEtcher; if you choose ArkOS instead, that project recommends Rufus, Win32 Disk Imager or Raspberry Pi Imager over balenaEtcher.

FAQ

Which custom firmware is safest for the RGB10 Max 3?
ROCKNIX, which has a device-specific install page, is the most reliable starting point. Batocera works via the Anbernic RGxx3 image; always confirm the RGB10 Max 3 is named on the project's current support list.
Do I need to replace the stock card?
No. Flash the custom OS to a separate microSD for the TF1 slot and keep your original card aside, so you can swap back at any time.
