Custom firmware on the Powkiddy A12 means running the community RK3128 Batocera build (from the RK3128-CFW project) in place of the stock Linux menu. Because the A12 came in several hardware revisions, you must point the build at the right device tree: write the Batocera RK3128 image to a microSD with balenaEtcher, then edit boot/extlinux.conf on the BOOT partition to use rk3128-powkiddy-a12-rev-c.dtb or rk3128-powkiddy-a12-rev-d.dtb. Insert the card and boot; first start expands the filesystem and loads RetroArch. Keep your stock card as a backup.
