Things you will need

• a CFW Nintendo Switch
• a Computer (Windows, Mac, Linux) or Raspberry Pi

Computer setup

Windows

Loopback packet capture driver

(If you have npcap installed, please uninstall and use winpcap instead. having both lnstalled will only cause issues)

• Download WinPcap

Download the lan-play client

lan-play client 32bit
lan-play client 64bit (if you're not sure, you probably want this one)

Open the lan-play client

Enter the lan-play server address

You can use Kinket's lan-play server (lan.kinket.app:11451) or one of the servers from the Lan-Play Website. You'll see the following type of output:

wget https://github.com/spacemeowx2/switch-lan-play/releases/download/v0.2.3/lan-play-linux # download the client from GitHub
chmod a+x ./lan-play-linux # make the client executable
./lan-play-linux  # start the client

Some Linux distributions might have lan-play in their package repository - feel free to use that instead of directly downloading the binary.

If you prefer building from source, you can follow the Raspberry Pi instructions

Raspberry Pi

There's no prebuilt binaries for ARM architectures - you'll have to build the client from source.

cd switch-lan-play
sudo mkdir build
cd build
sudo cmake .. # prepare makefile
sudo make # actually build the client

cd src
sudo chmod +x lan-play # make the binary executable
cp lan-play $HOME # copy the binary to your home directory, you can also copy it anywhere else
