I just purchased and assembled a Picade which is being run by a Raspberry Pi 3 B.
I really love it, it has a very satisfying look and feel, and could even be assembled by a relative noob such as myself.
One problem/question: I cannot map the two left hand side buttons to the joystick. Initially I thought I had done something wrong with my install, but then I realized that they control volume. Since I can control the volume through the RetroPie software, is there any way that I can use these two buttons in the joystick controls?
I have looked online, but can’t find any solutions which don’t involve rewriting parts of the operating system, which is a length I am not willing to go to. I feel that I am just about competent in Linux to rewrite a config file.
Can you give me any help?
