Demo Quake III multiplayer setup

Quake III is a wonderful shooter! With two Raspberry Pi and the great emulator RetroPie, it’s easy to setup an local network and play Quake III with multiple players. The RPis just need to be connected over a network switch and each requires an unique IP.

Installation
Follow the steps described in the tutorial RetroPie gaming, but without the section Hack for two keyboards. Then, duplicate the sd card, for instance with Gnome Disks. Then connect both Raspberry Pi to the network switch.

Change the IP
On both sd cards, the same IP is defined in interfaces. For the local network, these should differ. Boot one of the RPis and open interfaces with

Now, change the address in the code block defining eth0. For example, changing 10.42.0.51 to 10.42.0.100 here would be fine:

Save, then reboot.

Start a multiplayer session
Run RetroPie by entering

Choose Ports, then Quake III Arena. In the game, click Multiplayer and Create. Select a map, click Next and finally Fight.
Boot the second RPi now and start Quake III. Go to Multiplayer and join the open game with Fight.
