Interact GamePad won't work (Playstation)?
Yes, I tried playing with a official Playstation controlller and another 3rd-party controller, both of which work perfectly, so it's not the controller port.
I was going to ask this question on Yahoo! Answers, but half the people on there are just looking for points and don't know anything. Don't let me down, Instructables community!
P.S. If it helps any, the circuit board inside the controller are almost the same design as an official Sony Playstation Controller (Not Dual Analog/ Dual Shock). The only difference is that this controller board is much simpler.
