20 Controllers working on the Wii U...NES, GC, N64, Xbox, Joy-Con, etc.

Hi, this in depth video shows various different controllers throughout the years working on the Nintendo Wii U. Expensive adapters and converters are needed for these non standard controllers to work so this video is more like an experiment to show that it is possible. In real life you will just get a Wiimote Classic controller or Wii U Pro controller.

1. Sega Master System 1:03
2. Sega Mega Drive (Genesis) 2:36
3. NES 3:52
4. SNES 5:27
How to Sync up the adapters 7:11
5. N64 10:07
