a friend of mine installed the retropie-software to my device and when he started it for the first time, he had to choose keys for CHOOSE and BACK. He just typed A for CHOOSE and B for BACK on the keyboard, but I wish to have ENTER als CHOOSE and BACKSPACE for BACK.
Can someone tell me how to change the configuration?
BTW: The games are runnig fine, I really love this project. Thanks a lot to the developers!
