We'll be trying out multiplayer EmuVR for the next few hours. Join code is OEUPTDUU

Grab the latest version of EmuVR from here:
https://download.emuvr.net/EmuVR_1.0.11.7z
You'll also need the same roms as everyone else, those are here: 
http://file.vrg.party/emuvr20230128.zip
Extract that to your /games/ folder it should have each system there.

You should be able to join and see everything loaded up. If you have issues refer to https://www.emuvr.net/wiki/Netplay#Troubleshooting
You may try adding the EmuVR and Retroarch executables to your firewall exceptions.
