Installing XLink Kai

Follow the installation guide for your Operating System:

• Installing XLink Kai on Windows 7
• Installing XLink Kai on Windows 8
• Installing XLink Kai on Windows 8.1
• Installing XLink Kai on Windows 10

Network Configuration

Yuzu support in XLink Kai is still experimental and as such the setup process is a bit... bespoke.

Windows

These instructions are Windows 10 and Windows 11 specific. Older versions of windows should be similar.

Installing NPCAP

Due to licensing issues XLink Kai ships with WinPCAP which unfortunately is not compatible with loopback adapters. To solve this you will need to install NPCAP. Version 1.31 is known to be stable.

During installation the default options are fine, just keep hitting Next until finished.

Run kaiLoopbackBridge

1. Open Windows Explorer and navigate to C:\Program Files (x86)\XLink Kai\
2. Find kaiLoopbackBridge64.exe, right click, Run as Administrator
3. Read the warning, press any key to continue.
4. Select Nintendo Switch as the emulator type
5. The loopback adapter will now be configured automatically.
6. Close kaiLoopbackBridge. We will use it again later.

MacOS

Coming soon.

Linux

Coming soon.

Installing and Configuring Yuzu

Yuzu setup is quite simple, read the Yuzu Quickstart Guide to get set up.

Network settings

1. Once Yuzu is running enter the configuration by clicking Emulation then Configure
2. Click the System on the left, then click the Network tab
3. Under the General heading change Network Interface to the entry thats starts with XLink Kai Loopback Switch
4. Click OK
5. Exit Yuzu.

Playing a game on XLink Kai

Since Yuzu and XLink Kai are not able to communicate with each other directly (yet), kaiLoopbackBridge is used as a "bridge" between them.

1. Start XLink Kai and log in
2. Start kaiLoopbackBridge, navigate through the prompts and keep it open the entire time you are playing
3. Start Yuzu and start your game. Yuzu must not be running before you start kaiLoopbackBridge.
4. XLink Kai will now see Yuzu as a Nintendo Switch console under the Metrics tab
5. Navigate to a game arena and play!
