I'm trying to get a generic GameCube controller adapter to support multiple controllers on Nintendont for multiplayer. At the current moment, four controllers are recognized, the controller in the player 1 port works, but controllers in the player 2-3 ports do not work right. All of the buttons work properly, but the left joy-sticks keeps inputting up and left. This is what I have so far. I am using a YCCTEAM GC Controller Adapter.
