Wii Remote (Wiimote) & Nunchuck

The main input for the Nintendo Wii.

Steam Input Support

No

Linux Kernel Support

Yes, since 3.1 - hid-wiimote

Emulator usecase

Dolphin

Information: On third party Wiimotes

Many 3rd party Wiimotes do not have native Linux support this is being worked on a higher level. If you own or want to try them in RetroDECK and you should know that:

• Sometimes they will work with Bluetooth Passthrough mode in Dolphin (read more on this page).
• Sometimes they will be remember the paring to the Bluetooth adapter while other times they will not and needs to be synced for every game.

RetroDECK: Sync Wiimote Button Hotkey

RetorDECK has a built-in hotkey for pressing the Dolphins Sync Wiimote button Alt + W if you find yourself disconnected.
It can also be accessed from some controllers radial menu systems on for example the Steam Deck.

Steam Deck Tips:

The recommended method of playing is docked connected to a monitor/tv and to have a separate Bluetooth dongle attached to the dock.

• You need to have set a sudo password for the Steam Deck.

• It can be helpful to have a Keyboard / Mouse connected to the dock while setting everything up.

• It is good to sit close to the Steam Deck when paring the Wiimotes.

• As of now it is easier to configure Wiimotes in Desktop Mode then transfer over to Game Mode when everything is working (we will make easier tools later in the Configurator).

  • Open up Dolphin by launching it from the stand alone Configurator.
  • Make all the settings changes to connect the Wiimotes from the methods here on this page.
  • Try to launch a game from Desktop Mode directly in Dolphin by clicking on a game in the Dolphin interface.
  • If the paring works, the Wiimotes connects and the game controls fine with the Wiimotes in Desktop Mode it will as intended in Game Mode when launched from RetroDECK.

Dolphin and Wiimotes

Hardware Prerequisites for Dolphin:

• A Wii Sensor Bar alternative that can be wireless or wired.

• At least one Linux compatible Bluetooth dongle or built-in Bluetooth adapter.

Mod: Wii bluetooth adapter to USB

For those people that really likes to do hardware mods it is possible to buy the bluetooth adapter spare part from a Wii console and wire it as an USB bluetooth adapter for the best compability.

How to wire a Wii's Bluetooth Module to a PC USB Port

How-to configure Dolphin - Method: Emulate Wii's Bluetooth Adapter

This only works with the Official Wii Remote controller and is the easier method.

Step 1: Open Dolphins Controller Settings

Open `RetroDECK Configurator` -> `Open Emulator` -> `Dolphin` -> `Options` -> `Controller Settings`

Step 2: Change the Settings

Under Emulate the Wii's Bluetooth adapter

Change the values of Wii Remote dropdown lists

From Emulated Wii Remote to Real Wii Remote

Then enable the following checkboxes:

• Connect Wii Remotes for Emulated Controllers
• Continous Scanning

Step 3: Syncing the Wiimotes

The Wiimote can now be connected by pressing the Sync Button when a game is launched after changing the settings as long as the bluetooth is working correctly.
It will need to reconnect everytime when launching a new game, if everything works the reparing should be quick with the press of the A and without the need of pressing the Sync Button again.

How-to configure Dolphin - Method: Bluetooth Passthrough

This works with both 3rd party and official Wiimotes. It is a harder method with some downsides.

🛑 Warning 🛑

This method will make the Bluetooth adapters unusable for other devices while playing Wii Games and not other devices can connect to it except Wiimotes, that means all other devices will disconnect.

It could be good to have a second input method connected as backup like a wireless keyboard with a dongle or a controller with a dongle/cable.

Step 1: Find your Vendor and Product ID's

First you need to find our your Vendor ID Product ID for the Bluetooth adapter you want to use.

1. Open a terminal window
2. Type lsusb
3. It will now display all connected USB or BUS devices that you have connected. Example:

Bus 001 Device 003: ID 0bda:5650 Realtek Semiconductor Corp.
Bus 001 Device 004: ID 8087:0025 Intel Corp. Wireless-AC 9260 Bluetooth Adapter

ID 8087:0025 Intel Corp. Wireless-AC 9260 Bluetooth Adapter is the Bluetooth Adapter in this example.

The ID 8087:0025 left value is the Vendor ID while the right is Product ID.
Thus in this example: Vendor ID is 8087:Product ID is 0025.

Step 2: Create the rules file

You will need root privlages for this.

Open a terminal and type the following command and replace Vendor ID and Product ID respectively.:

sudo echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="Vendor ID", ATTRS{idProduct}=="Product ID", TAG+="uaccess"' | sudo tee -a /etc/udev/rules.d/52-dolphin.rules > /dev/null

from the example above the result should look like this:

sudo echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="8087", ATTRS{idProduct}=="0025", TAG+="uaccess"' | sudo tee -a /etc/udev/rules.d/52-dolphin.rules > /dev/null

2. Reload udev rules with: sudo udevadm control --reload-rules
3. Take out and reinsert the Bluetooth adapter or reboot if a built-in was used.

Step 3: Enable Bluetooth Passthrough in Dolphin

Open RetroDECK Configurator -> Open Emulator -> Dolphin -> Options -> Controller Settings

Change Bluetooth type:

• From Emulate the Wii's Bluetooth adapter to Passthrough a Bluetooth Adapter

Enable the following checkboxes:

• Connect Wii Remotes for Emulated Controllers
• Continous Scanning

Step 4: Syncing the Wiimotes

The Wiimote can now be connected when a game is launched, but it will not connect before that. It will need to reconnect every time when launching a new game.

You will need to Sync Wiimote by pressing 1 and 2 together on the Wiimote or the Sync Button (under the backplate), when launching a game.

Sometimes you will also need to press the Sync Button on the Emulated Wii in the Dolphin Interface, this can be found in the controller menu in Dolphin or RetroDECK has a built in shortcut for this Alt + W that is also be accessed from the RetroDECK Radial Menu system on the Steam Deck while in Game Mode under Dolphin.

Extra: Troubleshooting and tips

• Always sit close to the device when you are doing the initial paring.
• Sometimes it can take a while before the paring happens, specially on 3rd party Wiimotes. You might need to try multiple times with both the Sync Button + Sync Wiimote.
• If you want to play with normal controllers as Wiimotes again the best way is to change back to: Emulate the Wii's Bluetooth adapter setting.
• If the udev rules you created in Step 2 are wrong and Dolphin can not get Bluetooth access, it will display a error message and crash. If that happens go back and make sure that the file in /etc/udev/rules.d/52-dolphin.rules and the content is correct.
