If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.
I've been searching the forums for this for a while but still can't find this. I don't know where to attach the Super Joy III and Hip Gear (whose screen is disconnected from the controller half). Anyone have a clear pinout?
