Open up a NeoGeo game, doesn't matter which one. Press F1 on your keyboard to bring up the Retroarch GUI, go to Quick Menu then Controls. Scroll a little til you see on the left "User 1 Button A" and so on. The left column is the actual NeoGeo controls and the right column is your controller buttons. Go to each button and push left or right on the d-pad til you got your buttons the way you want. Once you have the buttons the way you want scroll back up and little and look for "Save Core Remap File".
Everything should be good now. Should.
