This has been fixed in SDL upstream.

Oh, but cemu still needs to build with libusb enabled for the GCN API to work natively, I think the license concern with that was fixed?

Wiimote is not what you select for the GC adapter, SDL is.

I tested two products.

Currently, Mayflash GameCube Controller Adapter for Wii U, PC USB and Switch 2/Switch/OLED Model, 4 Port(W012) is not working. https://www.mayflash.com/product/W012.html

I am using Mayflash GameCube Controller Adapter for Wii & Wii U（Dual Pack) . https://www.mayflash.com/product/W0142.html

It seems that GameCube Controller can be used through WiiRemote API, but libusb does not work well.

If it worked well, Mayflash GameCube Controller Adapter for Wii U, PC USB and Switch 2/Switch/OLED Model, 4 Port(W012) should have worked well too.

In Cemu the Wiimote API is wii motes only and attachments such as the classic control.

GC API enabled builds (pre-2.0) exposed a GameCube type in the control menu.

The adapter will work with SDL albeit with the b and X swapped(iirc), and smash will treat it as a pro controller or wiiu pad

Oh. And Wii motes must not be added to the mapping before the gamepad or pro controllers
