Greetings,
This is a minor annoyance at best, but when I play a game like SSBB on the Dolphin wii core it will detect my controller as a gamecube controller and the controller I selected in the retroarch.
For example when I want my contoller to be emulated as a wiimote + classic controller it will lock the first player in with a gamecube controller and the second player as the classic controler. In the beginning it used to give me allot of double input trouble in the menu, but this was fixable when selecting the controller type as none, where you are only left with the gamecube controller.
It would be wonderful if someone knows the source of this problem. 
Thank you for your time.
