Since this emulates the Switch’s ability to do local wireless multiplayer, it does NOT rely on Nintendo’s servers and does NOT require a Nintendo Account. Yuzu, on the other hand, employs virtual rooms to allow players to create and join game lobbies within said rooms. Here, one player would act as the host and all others would connect to it. The Switch console uses the LDN service to scan for other Switch consoles using Wi-Fi and connects all players.
Yuzu’s Local Wireless multiplayer (LDN) differs a little bit when compared to the Nintendo Switch. We highly recommend using our installer to always stay up to date on both Mainline and Early Access builds.
