Help to get the Switch Online GameCube controller to work on PC??

thekarter104 · Friday at 12:40 AM

So I have this GameCube online controller for the Switch 2 and when I want to connect it, the Bluetooth doesn't work, but that's no problem, I have a long USB-C cable.

There is this app Procon 2 which makes input work, but not correctly.

I open Dolphin and configure the controls. All buttons work except the sticks... Left analog stick left doesn't work and C-stick doesn't work at all.

Tried another emulator and it just refuses to work...

What to do now?

Sorry for the late reply, just got back.
I added Dolphin to my non game steam library and controls still don't work, or do I need to start a game?

From the picture I see you use some sort of program? Looks cool. What do I do?

You need to pick the controller in Dolphin settings if you go the Steam route, as brought up earlier. Note that this only works via USB.

That's Steam with an Aero/WMP theme of some sort.

There are a couple of other ways to use the controller on PC with Bluetooth LE support too, namely Pairing App (Linux/macOS/Windows). There is also a Windows-exclusive utility I can't find at the moment, but it is supposed to work for all Switch 2 controllers.

Alternatively, you can combine WUP-028 and a BlueRetro GC adaptor.

I wrote more about the controller here if you'd like to know a bit more of what I found out about it (as well as other GameCube controllers).

Yes, I'm on USB. And yes I've set it in steam to use the steam input.

I'm not sure if you read that right. Aside from using Steam Input on Steam side, you need to select the Steam Input controller within Dolphin under its settings.

That's the problem. Nothing works. Not sure what to choose, but I tried everything from the list.

Usong Nintendo GameCube controller makes it not work correctly. Steam Input is enabled from Steam settings. So yes, I tried to configure it in Dolphin, but what I do? From the list of controllers, nothing works with the GameCube controller.

Looks like Steam Input was configured for Dolphin as Xbox 360 controller on your end, so pick one of those entries.

Also note that inputs in Dolphin are unbound by default, so you may need to manually assign buttons.

It seems to work on one of the Xbox 360 profiles. Had to click atleast a button twice before it started working correctly.

But now I have this problem which I don't have on my other PC which is even older.

Edit - seems setting it to OpenGL fixed it. I have ZERO idea what it all means as I'm no PC gamer. But emulators use these terms aswell and now I can connect it and play with mods now.
