I’ve been working on a Retropie Arcade cabinet, and I’d been having some trouble with getting the buttons to work. I later learned that the GPIO board wasn’t able to be used with retropie, so I bought this (http://www.amazon.com/gp/product/B00UUROWWK?keywords=usb%20encoder&qid=1445207699&ref_=sr_1_1&sr=8-1) USB encoder in hopes of getting the controls to work.
The only problem is, I don’t know how to set it up. It’s acknowledged as a gamepad, but I have absolutely no idea about how to set up individual controls, let alone something like a joystick.
