Hello, I'm having a bit of trouble with this. Everything works perfectly fine except for trying to get multiple controllers to work.
I'm testing the Wii U GC adapter to work with PC and its working just fine. I set player one controller and player two controller to "vJoy Device" which is what the computer is reading it as. I can set the controls to the buttons I want without any problems. The problem is that player one can control things just fine, but when I try to do anything with controller two, nothing happens.
Is this because the device that it's reading from is just the one Wii U GC adapter even though their are four ports for the 4 GC controllers able to be plugged in?
