RetroPie

Hey all, last week i was messing with my old rpi i had laying around. I had a couple of failed manual installs, before i realized there was just an image of retropie on the installer, and used it...

I messed around, installing some other things from the command line, that I read about on other dummy guides.

Well, i played a bit, and my saves for Metroid are borked... And the game has hotkeyed saves loads etc that are tied to reteoarch... I have a simple Buffalo SNES controller... So i dont have spare keys on it to rebind them to, and cannot completely unbind them even with a keyboard.

My question is, is retroarch part of the retropie install, or is it something i installed in the chaos of crap i did after my initial install? Can i uninstall it completely, or just reflash retropie? I have seen all of the losta regarding resetting the hotkey for the shortcuts... None of it seems to work, at least with this controller. Im supremely frustrated. I spent an hour or two assing with it last night... Configuring shortcuts from inside the game, without a rom loaded, and could not get any satisfaction.

Im pretty rudderless here, and obviously clueless about the inner workings of these things. So appreciate any advice.
