@tehswiftone said in Single GPIO button:
Add this inside of your controllers config, don't forget to replace button with a proper button ID. This will be similar to exiting an emulator, you will use select + button to use it. So don't worry about it taking up a button on your controller.
input_volume_down_btn = "button"
input_volume_up_btn = "button"
I have mine setup to use Up and Down on the D-pad. Just change the "btn" to "axis".
input_volume_down_axis = "+1"
input_volume_up_axis = "-1"
