Only Official GC Controllers will work the buttons are OK but I have slight movement from the R and C Stick making it a bit difficult on some games e.g. Star Fox when you try to roll it will on go on its side?
The rumble feature does not work with the N-Rage plug-in , as far as know it works with a specific plug-in but I don’t remember the name of it. Because they were problems when using that plug-in as the buttons become very sensitive making games hard to play and as I had a slight movement in the R button on Star Fox the ship was always on its Right side.
