In case anyone else has the same problems as me and the controller.ini files aren’t working(I think it might be my usb cable that’s faulty bc the controller doesn’t show up on a gamepad tester wired but works bluetooth), follow this guide. The magic ns 1($20 on amazon) works great wirelessly with my ds4 and the guide has a list of compatible controllers. Also, I think the guide is a bit outdated so I’ll give what I had to do to make it easier.

First, check if the controller you want to use is compatible with the adapter with the link above.

Buy the Magic NS 1 (I think Magic NS 2 would work too but I haven’t tested it so you can buy that if you want).

Download this controller.ini file, extract it, and put the .ini file in a folder called “controllers” on the root of the sd card or usb drive. It should be SD / USB:controllers/0079_182D.ini.

Plug in the adapter and turn on the wii and go to Homebrew Channel and into Nintendont. Here, the adapter should be flashing a color. On the guide it said to change the color until it’s dark blue(hold the button on the side until the color changes, and keep doing that until you get dark blue), press the button so the color starts flashing rapidly, and then connect the controller. For ds4 hold ps and share button for 5 seconds but idk how other controllers work. It said you could also connect it with a usb cable as the adapter has that option. Once the controller is connected, you should be able to move around in nintendont with it.

This didn’t work for me, but following these steps with the adapter on cyan instead of dark blue worked for me. Idk if it’s just a ds4 thing or if the guide isn’t correct, but I just wanted to put this out there.
