    Hi Retropie forum.
    I’m working on a compact, portable Retropie powered project.
    I would like to connect the built in controller through GPIO, much like the Adafruit PIGRRL Mini.
    How could I do that on a fresh install of Retropie?
    Can I just write a GPIO pin name instead of a button number on a gamepad?
    Thank you in advance
