Y Team Controller Adapter for Gamecube, Compatible with Nintendo Switch, Super Smash Bros Switch Gamecube Adapter for WII U/PC with 4 Port

I did not do a full test, but the thing did its job, and with little fuss. It did not work correctly on first link, but resetting the system helped, and it has been fine since. I used the WiiU mode for linking to the Switch. It works fine with MarioKart 8 Deluxe + 2 Wavebirds. TBH, Playing on the new pro controller is a much better experience, but this was cheapest way I had to add two extra players.

Bought this to play melee online with friends and it works great. They originally bought different ones and even after some googling and messing with drivers they couldnt get them to work and both ended up buying this one which is working for them too.

Solid product

This was delivered really fast, and it is really compact and easy to use. The switch fits in it and it has a lot of slots for the games. Extra controllers can also fit in there, and it is made really well for travelling. The quality feels really good, and the two screen protectors are a perk of the price. The glass tempered screen protectors are really nice.

It is great for smash brothers and works like a charm.

Bueno

I am using this for my 2015 Macbook Pro. When I boot into bootcamp, it works well, however, in MacOS dolphin, it allows me to input my controllers, but the joysticks are not working. When I go into Super Smash Bros, it straight up has no response. WHY IS THIS HAPPENING???? It says to contact their service, but it DOESNT SAY HOW! I am connecting only the black, both black and gray, and its on PC. I even tried in Wii U and used dolphins Wii U mode, and it STILL DOESNT WORK! Edit: After customer support helped me out and sent me a replacement, everything is all good!

Worked really well. Just make sure the switch is in the proper position for what you’re using it for.
