Powkiddy RGB20S — Troubleshooting

Quick answer

Button combo

SELECT+START(exit game, twice)·SELECT+X(RetroArch menu)·POWER(hold for menu)

Steps

  1. 1Won't boot / black screen: re-seat the boot microSD and re-flash the OS image with Rufus or Win32 Disk Imager; a bad card is the usual cause.
  2. 2Games missing: confirm ROMs are in the correct folders on the second microSD, then refresh the game list from the menu.
  3. 3Stuck in a game: press SELECT + START (twice for some emulators) to exit, or open the RetroArch menu with SELECT + X.
  4. 4Won't charge: use a low-wattage USB-C charger and a known-good cable, then let it charge before retrying.
  5. 5Always shut down from the menu (hold POWER), never by pulling power, to avoid corrupting the card.

Most RGB20S problems trace back to the microSD cards or to improper shutdowns; treat it like a small Linux PC. A bad or poorly written boot card causes black screens and boot loops, so re-flashing a fresh image with Rufus, Win32 Disk Imager or Raspberry Pi Imager is the first fix. Use SELECT + START to leave a game and SELECT + X for the RetroArch quick menu. Always pick Shutdown from the menu rather than cutting power, and use a quality card formatted by the imaging tool.

FAQ

It powers on but the screen stays black.
The boot microSD is likely faulty or badly written. Re-flash the OS image with Rufus or Win32 Disk Imager onto a quality card and try the boot slot again.
How do I exit a game?
Press SELECT + START (twice for some stand-alone emulators). You can also open the RetroArch menu with SELECT + X and quit from there.
