Sorry, but you're using a 3rd party image bundled with the hardware, which we don't/can't support. Note that selling RetroPie is against the project's license - https://retropie.org.uk/about/legal/, so you've been scammed, since RetroPie is free/open source software.

@Clyde Thank you for the kind words :)

@pengu1n said in GPIO Controls Not Registering After Launching Games: [WARN] Input device ID 3 is unknown to this libretro implementation. Using RETRO _DEVICE_JOYPAD. That's because of the RA's configuration - try resetting the configuration to default by copying the retroarch.cfg.rp-dist files over the retroarch.cfg in the /opt/retropie/configs/all/ folder.
