Hello, I have been dabbling in RetroPie for a little while now, (At least a month?) and have recently taken on a project of gutting and “RetroPieifying?” a Nintendo Gamecube. I’ve installed the latest update of RetroPie, along with the Gamecon drivers (As well as the sibling one, forget what it’s called) through the RetroPie-Setup script. I am using a RPi 2, with the controller’s ports connected as follows(View the image that should be attached, if not, http://www.int03.co.uk/crema/hardware/gamecube/images/gc-socket1.gif):

2 – GPIO 2
3, 4, 7 – GROUND
6 – 3.3v
(No mysterious pin 5)

I then use this command:
sudo modprobe gamecon_gpio_rpi map=0,0,0,0,3,0
Also, I tried adding it to /etc/modules, and am VERY unsure about how, and am pretty sure I did it wrong.

Finally, onto the problems!
I power on. Nothing acknowledges the controller. I use the modprobe, and still no acknowledgement. I navigate to the correct folder, then use jstest. Also unsure of this command. (jstest /dev/input/js1) Play with the controller, nothing happens.

I’m sorry if I’m missing info or have too much, this is my first post on ANY forum.
