LDN Multiplayer

Ryujinx offers multiplayer support over the internet via LDN/Local Wireless emulation in a special preview build. Furthermore, all versions of Ryujinx now also support LDN connectivity with CFW Nintendo Switch consoles via ldn_mitm, and LAN Mode connectivity with Switch consoles on games with LAN functionality!

Requirements
Configuring LDN

Requirements

  • An active high-speed internet connection.
  • The Ryujinx application must be enabled for inbound traffic in your firewall if you are the game host. Windows Firewall, if enabled, will pop-up prompting you to allow access. Make sure to allow it!
  • UPNP enabled in your router/firewall for P2P mode (most routers already have this enabled). Otherwise the game can still work (albeit with higher latency) using the proxy host.
  • The same game version as those you are playing with e.g. Animal Crossing: New Horizons 2.0.5; mixing game versions will not work!

Configuring LDN

To setup LDN on the latest Ryujinx builds go to Settings > Options > Network

To play ONLINE only select ldn_mitm under Mode and leave the Guest Internet Access/LAN Mode disabled.

To play Locally (via same WiFi/LAN) select both ldn_mitm under Mode and enable the Guest Internet Access/LAN Mode.

More info on ldn_mitm

  • ldnMitm will modify local wireless/local play functionality in games to function as if it were LAN, allowing for local, same-network connections with other Ryujinx instances and hacked Nintendo Switch consoles that have the ldn_mitm module installed.
  • Multiplayer requires all players to be on the same game version )i.e. Super Smash Bros. Ultimate v13.0.1 can’t connect to v13.0.0)

More info on Guest Internet Access/LAN Mode

  • Allows the emulated application to connect to the Internet.
  • Games with a LAN mode can connect to each other when this is enabled and the systems are connected to the same access point. This includes real consoles as well.
  • Does NOT allow connecting to Nintendo servers. May cause crashing in certain games that try to connect to the Internet.
  • Leave OFF if unsure.
