Creating an Account

To begin, you'll need to register for an XLink Kai account and download the program. Click on 'Sign Up' at the top of the XLink Kai home page and fill in your details, then click Submit. You then need to verify your email address and consent to the XLink Kai data collection policy (GDPR compliance). Please be sure to read the Acceptable Use Policy.

Installing XLink Kai

Follow the installation guide for your Operating System:

Wii console setup

Your Wii console will require specific network settings and homebrew applications. Unmodified Wii consoles will not be able to play GameCube LAN multiplayer.


If your Wii does not currently have the Homebrew Launcher installed follow the guide here before continuing:

Connecting to your network

our wii console will need to be configured with a specific IP address to be used on XLink Kai. This address is unique to your console to avoid addressing conflicts with other players. If the address is not set correctly XLink Kai will ignore your game traffic and show an error. The best way to play GameCube LAN multiplayer on XLink Kai is with a fully wired set up. You will have the lowest latency (ping) and most stable connection possible. Using a wireless connection may work, but it will be unstable.

Wired Connection

To play on XLink Kai the network settings of your console must be configured very specifically:

  1. Connect your LAN adapter to one of the rear USB ports on your Wii console and connect an ethernet cable to your network.
  2. Navigate to Wii Options from the home screen

  6. Select Console Information

  7. Your Wii's MAC addresses will be displayed. We're interested in the LAN Adapter MAC Address. Write down the last 4 digits. In this example that is 66-54

    If the LAN MAC address is greyed out and is all zeroes make sure your LAN Adapter is plugged in then power off your Wii console and power it on again.

Wireless Connection

The process to configure a wireless connection is very similar to the process for a wired connection. Follow the same steps but use the MAC address for the wireless adapter.

Installing Nintendont

Playing GameCube LAN multiplayer on a Wii is not possible with the built in GameCube emulation/hardware. We must use a homebrew application called Nintendont instead. Follow the instructions at to install Nintendont. This process is not covered in this guide.

Create ISO files of your game that you want to play using your copy of the game and put them on your SD card or USB device. The Dolphin wiki has a comprehensive guide on the process

Configuring Nintendont

  1. Launch Nintendont

  7. When the other players are ready select Yes and press A ButtonIcon-Gamecube-A.png at the same time.
    GC MKDD 3 choose yes.png
  8. Wait for the games to connect. Usually the connection happens when the counter says 170. If it passes below 150 its best to abort by pressing B ButtonIcon-Gamecube-B.png and trying again.

  9. Your console should now be connected to the other player(s). Once everyone is connected press Start ButtonIcon-Gamecube-Start.png to continue. You can not join games that have already started.
