Most RG28XX problems trace back to charge, the microSD cards, or per-game emulator settings. A device that won't power on is usually flat — charge it over USB-C and force a restart by holding POWER. Boot failures and black screens are most often a bad or loose TF1 (OS) card, so re-seat it and, if needed, re-flash the official Anbernic .img with balenaEtcher; an unreadable TF2 card can be re-formatted and reloaded on a computer. For poor in-game performance, switch emulator cores from the in-game menu in RetroArch. This is a DRAFT for human review.

FAQ

The screen stays black on power-up — what now?
It is usually the TF1 (OS) card. Power off, re-seat the card, and if it still fails re-flash the official RG28XX .img with balenaEtcher. Charge over USB-C first in case the battery is flat.
My microSD card isn't detected.
Power off and reinsert it firmly. If still not seen, check it on a computer; re-format and re-image the OS card, or reload files on the ROM card. A failing card may need replacing.
