As of 4.0-4599, Dolphin has built in support for Nintendo's GameCube controller adapters for the Wii U and Switch, the only official USB GameCube adapters available. With Dolphin's implementation, the GameCube controller is auto-configured and calibrated, with full rumble support. Wireless controllers and bongos are supported.

In addition to the official adapters, third-party adapters that are compatible with the Wii U are also supported. Such third-party adapters generally have a switch for choosing between PC mode and Wii U mode. If your adapter has a switch, you have to set it to Wii U mode before following these instructions. Official Nintendo adapters don't have a switch.

When using the flatpak version of Dolphin, some Linux distributions will additionally require you to specify access to all devices. This can be done with the --device=all command argument, e.g.:

Due to the nature of Apple's HID implementation, all HID devices (including non-standard ones) are intercepted by IOKit's HID driver. Since the adapter does not supply a valid report descriptor, this makes the IOKit driver useless for direct communication. Thus in order to use adapters on macOS, a driver needs to be installed that simply grabs and ignores the adapter, and permits a lower-level connection (like the one Dolphin makes).

Once installed, Dolphin should be able to recognize that the adapter has been plugged in. You do not need to configure the controllers manually within Dolphin's controller settings but any controllers plugged into the adapter should work immediately.

On El Capitan (10.11) and later, the unsigned Kernel Extension will fail to load.The only workaround is to disable kernel-extension signing verification, which can be done in macOS Recovery Mode.This will lessen security, and is not recommended.

On Windows, the GameCube controller adapter will need a custom driver to let Dolphin detect it and use it, Zadig can help you with it. From 5.0-2472 to 5.0-10617 it was possible to alternatively use UsbDk, but it is no longer supported in current versions.

The software that utilizes vJoy drivers, such as GameCube USB Adapter Driver, can treat the GameCube controllers as generic gamepads for Windows. They can be configured in Dolphin like any other controller. Unlike vJoy, Dolphin's native support will offer more straightforward and added missing supports from vJoy (i.e. force feedback), and offer better latency. vJoy and Dolphin's native support conflict with one another, so to use the native support in Dolphin, driver services must be stopped through GameCube USB Adapter Driver 's window. You probably already have ran Zadig setup if the GameCube USB Adapter Driver version is v3.0 or later. Skip to #Dolphin Setup below if you haven't encountered any problems with it.

Plug in the GameCube controller adapter if it hasn't been already. Download and launch Zadig. If you're using the a third party adapter, like the one from Mayflash, make sure you switch it to "Wii U" or "Switch" mode or Zadig won't pick it up properly.

Android doesn't require anything special to make the adapter work. Under the gamepad controller settings; For each controller that you want to use the adapter with, change the selection from Emulated to Gamecube Adapter. After that point, make sure to start the game with the adapter plugged in and Android will ask if you want Dolphin to have permission to use the device.

There is a bug in Android's USBManager framework that sometimes causes Dolphin to be incapable of reading the adapter. In these instances a toast window will pop up asking you to unplug and replugin the adapter. Do so and Dolphin will be able to read the adapter after that.

With any necessary installation complete, run Dolphin, and check Direct Connect under GameCube Adapter in the Controller Settings, then restart Dolphin. Set GameCube ports to Standard Controller corresponding to each port on the adapter that is plugged in with the actual GameCube controller. The setup for the adapter is now completed. To test, simply start a game that uses GameCube controllers.

With any necessary installation complete, run Dolphin and click the GameCube controller dropdown. Select GameCube Adapter for Wii U on any slot that you wish to use the adapter for. Hitting Configure when this is selected allows you to turn rumble off/on per controller, as well as a toggle for using the DK Bongos.

It's worth noting that only the first instance of Dolphin Emulator will detect the adapter. Another instance will detect the second adapter if inserted, and so on. If the Dolphin Emulator couldn't detect the adapter, it's possible that you already have another one running.

If the adapter is not detected at all, then it may only be a matter of changing USB ports and restarting Dolphin, or its driver/setup might have recently been changed/overridden. You should follow the instruction again from one of the sections for your system.
