For awhile I was holding out for the 8bitdo version, but I'm so happy I went with this Armor3 brand instead. As you can tell by my photo, I've got many retro style controllers such as the following:- Original Gamecube-Evoretro (3rd party Gamecube controller)-Samus wii controller-NES Classic controller-SNES controllerI can confirm they ALL work perfectly with this adapter! I do notice when using Gamecube controllers that the adapter swaps the shoulder buttons. This does not bother me at all because I prefer the swap, but if it bothers you then you have the ability to remap the buttons in system settings on your switch. You can remap your controllers to however you wish. I am so happy this adapter allows this because not all controllers (such as PowerA's version of the gamecube controller) allow remapping. So it's nice to have an adapter that does allow.Lastly, the fact that no batteries are needed is a huge plus!! It's rechargeable.Overall, great little adapter! Highly recommend.
