The Nintendo GameCube controller continues to live on despite it now being two decades old. People just cannot get enough of the thing. One fan modder to his love of the classic to the extreme and outfitted his Switch dock to be natively compatible with the controllers.
Redditor “i_AM_hank” managed to use some tech engineering skills to install a quad-array of GameCube controller ports to the rear of his Nintendo Switch dock:
As you can see, the ports don’t even get in the way of the functionality of the rest of the dock; that’s pretty clever. While the modder does have an extensive report as to how he made this makeshift adapter work, here’s the basic rundown. The modder removed the mainboard from a third-party GameCube-to-Switch adapter and installed it into the dock. He then wired up the two front USB ports of the dock to the adapter’s mainboard, so it would function as if it were a regular external device. However, the modder doesn’t have to permanently sacrifice both of those ports. He also installed a button that will activate the adapter on demand. When not in use, it can be turned off and regular USB functionality will be restored to be used with over devices.
If you have some time on your hands, you can try to use i_AM_Hank’s guide to create a rig of your own. But, for us peasants, guess we’ll just have to stick with using regular adapters or GameCube-style controllers that are natively compatible with Switch.
