lets try the multiplayer feature…
if you don’t find anyone you can test yourself by creating a second citra instance in portable mode:
Simply duplicate your citra install folder (where citra-qt.exe resides), in this second citra folder create a new folder and name it
user. copy and paste the contents of
%appdata%/citra to it.
launch this second citra instance and go to Emulation > Configure > System > System and click on ‘Regenerate’.
now simply open both citra instances, on one of them create a room (Multiplayer > Create Room) and on the other connect to it (Multiplayer > Direct Connect to Room, connect using the same port and leave the IP field empty).
