Hello! I'm using Nintendont on my Wii U. Little problem here: I bought two "KADE miniconsoles" (KADE is a "gaming device that connects retro gamepads and controllers to a huge variety of computers and consoles using plug and play detection"). I can now connect the KADE to WiiMote or to a USB port on the Wii U and use GameCube controllers (or whatever controller I want). I can play with two controllers using two KADEs connected to two WiiMotes (in this case, KADE emulates two Classic Controllers). I can also play with one controller using one KADE connected to one USB port on the Wii U (in this case, KADE emulates a SSB GameCube Adapter with one GameCube controller connected to it - even if I use other controller connected to KADE, the point is that the KADE connected to the Wii U via USB emulates this adapter). But I cannot play with two KADEs connected to two USB ports on the Wii U. After trying various firmwares that one of the developers rebuild for me to test with the Wii U, the conclusion is that Nintendont doesn't recongnize two SSB GameCube adapters connecter at the same time - the developer told me that he can use two of this adapters at the same time on the SSB for Wii U. We had also set one KADE to be always as controller 1 and the other to be always the controller 2, and as a result we have only controller 1 or only controller 2 connected, demonstrating that Nintendont doesn't really recognize two SSB GameCube Adapters at the same time. This could be, at this time, the only way to me to play with two GameCube controllers with vibration (I can play with two controllers connected to the WiiMote simulating a Classic Controller, that don't have vibration). Could someone help me making Nintendont work with two SSB GameCube Adapters to play with them using two KADEs? Thank you all for the hard work here!!
