oohhhhhhhh. Thank you so much for all your help. Also will this work on a raspberry pi 4?

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.

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.
