Review on 🎮 Y Team Gamecube Controller Adapter for Nintendo Switch and Wii U (Compatible with Super Smash Bros), PC, 4 Port, Black - Model W046 by Mike Bucher

Although I didn't put the product in PC mode, it worked immediately with Dolphin, which bothered me as many of these adapters claim to work but don't work. I already had the drivers needed for the OG adapter installed, so I leave it in Wii U mode and plug it in. There was no noticeable input lag and there were no crashes during the game. When I then connected it to the switch, I had no problems at all. Apart from the different feel of the plastic and switch on the back. It could also be the original GC adapter. If you need an adapter for Dolphin, Smash 4 or Switch games this is by far the best option out of several fakes I've seen/used. To use Wii U mode on Dolphin just follow the instructions on their wiki to get the normal GC drivers and it will work without any issues.
