@retropieuser555 I'm baaaack lol

Ok, so updating my retropie didn't help with the save game issues. My son was playing some Kirby games, and they were getting erased every day he logged in.

So, I finally found "resetromdirs" and did it! However, now I have this ...Error after using ResetRomDirs

Although there's a command line, I can't seem to type anything using the controllers. Any help would be appreciated, thank you!

You can choose a hotkey enable button when you configure your gamepad and this will set it also in RetroArch so you can trigger an action with 2 button combos - see https://retropie.org.uk/docs/Controller-Configuration/#hotkey.
However, this is an emulator feature (RetroArch) and not a global/general input configuration option that will work in any program (including EmulationStation).
