I would like to know what's needed and preferably some instructions for registering buttons and PC recognizing it as gamepad plug-n-play.
I threw idea to mod NES usb controller with tactile buttons so they work every time Instead of flimsy feel. And friend who got his DIY 3D printer said he could make custom controller body and I could get PCB and electronic apartment done for it. Only problem is I couldn't find any instructions or information except using arduino which doesn't get recognized as gamepad and it's bulky as cow crap.
It would be grate for future projects if I could get joysticks working for it too.
