I didnt configure the buttons and now have no "go" button

[thultisu]

I got frustrated configuring the buttons for the Ames controller and the only buttons that configured are the "right" button which takes you down, the "up" button which takes you up, the "select" button which only pops up the config menu, and the "A" button which only works as a "back" button. Is there a way to delete configurations without having a "go" button? If I hook up an Ethernet cable and tie it to the laptop, what steps do I take to reset all configurations I have messed up?

@thultisu Enable SSH, login as the pi user (password is _raspberry), run sudo ~/RetroPie-Setup/retropie_setup.sh, go to the Emulationstation package and reset the controller configuration.
