+Time to grab your friends and jump right in! + + + +## What is this? + +The Nintendo Switch console supports various multiplayer options. +Among these, the following options are useful when you want to play multiplayer with other Switch consoles. +{{< imgs "./multi.png| Table indicating yuzu's supported Switch multiplayer modes" >}} + +{{< imgs + "./Switch_Conn.png| Graphic demonstrating the key differences between the three wireless modes" +>}} + +

+The Switch's HorizonOS uses the LDN service for all Local Wireless communication.
+This is why Local Wireless Multiplayer can also be referred to as LDN Multiplayer. +

+ +Thanks to the incredible efforts of our developers [FearlessTobi](https://github.com/FearlessTobi) and [german77](https://github.com/german77), Local Wireless Multiplayer in yuzu is no longer a dream! +Special thanks to [spacemeowx2](https://github.com/spacemeowx2/) and [all the contributors](https://github.com/spacemeowx2/ldn_mitm/graphs/contributors) of the [ldn_mitm](https://github.com/spacemeowx2/ldn_mitm) project. +Without their extensive reverse-engineering of the `LDN` service, and the gracious [license exemption](https://github.com/spacemeowx2/ldn_mitm#licensing) for yuzu, this would not have been possible. + +
+
+

⚠️ Attention

+
+

+Currently, Local Wireless Multiplayer (LDN) is only supported between instances of yuzu.
+Multiplayer between yuzu and a real Switch or between yuzu and other emulators is not supported! +

+ +## Where can you get it? + +The Local Wireless Multiplayer feature is now available in the latest version of the Early Access release. +We will be working to polish this feature and make this available to the Mainline builds soon. + +

+If you're using the yuzu installer, you'll automatically be updated to the latest build.
+If you're not using the yuzu installer, please download it from our Download page.
+
+We highly recommend using our installer to always stay up to date on both Mainline and Early Access builds. +

+ +## Local Wireless (LDN) Multiplayer + +yuzu's Local Wireless multiplayer (LDN) differs a little bit when compared to the Nintendo Switch. +The Switch console uses the `LDN` service to scan for other Switch consoles using Wi-Fi and connects all players. +Here, one player would act as the `host` and all others would connect to it. + +yuzu, on the other hand, employs virtual rooms to allow players to create and join game lobbies within said rooms. +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. +While on a real Switch, you’d be limited to the people in your immediate vicinity, yuzu boasts a complex server/client infrastructure that forwards a game’s wireless communication across the internet. + +In order to connect with other players, players simply need to join the same room within yuzu’s Public Room Browser. +But, before opening the Public Room Browser, you will have to first configure your network interface in yuzu. + +You can find this setting under `System -> Network` and you need to select your internet connection from the drop-down as shown below. + +{{< imgs "./network_interface.png| yuzu's Network Interface configuration" >}} + +Out of the box, we provide you with an assortment of public rooms hosted across the world by yuzu. +Creating and joining rooms is extremely easy in yuzu and can be done in just a few clicks. + +{{< imgs "./room_browser.png| yuzu's Public Room Browser" >}} + +If you’re a [Verified User](https://community.citra-emu.org/signup), you can create your very own public room for people to join. +These public rooms can be seen by anyone using the Public Room Browser, but you can also password protect them to restrict users' access. +Verified Users will have their forum nickname and profile picture populated in the chatroom. +
+ +
+

⚠️ Reminder

+

+When hosting a room, remember to port forward or your friends won’t be able to connect! +

+ +If you prefer not to sign up for our platform, you aren’t out of luck! +Unverified Users still have the ability to create unlisted rooms, directly connect to unlisted rooms, and can join any yuzu hosted room. + +Do note that Verified Users will have their privileges revoked for violating any yuzu policies while in the room chatroom. +Please respect the `Preferred Game` listed in publicly hosted rooms, as even unrelated games will add to the bandwidth load. + +{{< imgs "./room_chat.png| Public Room chat and moderation features" >}} + +

+You can use these rooms for LAN mode games as well — instead of ZeroTier or Hamachi. +

+ +Please visit [our multiplayer guide](https://yuzu-emu.org/help/feature/multiplayer/) for further help with Hosting, Port Forwarding, Authentication, and Moderation of your publicly hosted rooms. + +## Development + +FearlessTobi began development by leveraging the existing virtual rooms infrastructure from [Citra](https://citra-emu.org). +Due to code similarities between yuzu and Citra, this tried-and-tested infrastructure easily became the foundation of this feature. + +Now that the virtual rooms were taken care of, Tobi moved onto the `LDN` service and its protocols. +Using the research and code from the [ldn_mitm](https://github.com/spacemeowx2/ldn_mitm) project, he implemented the necessary changes for yuzu instances to communicate with each other over these virtual rooms. +During this process, Tobi put an extra emphasis on ensuring no personal data, such as IP addresses, was leaked to the other room members. + +As the feature slowly matured, Tobi began utilizing yuzu's internal team of testers to verify the feature across several titles for compatibility and performance validation. + +With the multiple testing iterations, various bugs and glitches were found. +german77 relied on his own reverse-engineering and hardware tests to debug these issues, which then made it easy for the team to fix these various problems. +He also made several UI fixes to improve its usability and brought the codebase up to yuzu standards. + +## Compatibility + +Please note that as this is the initial release of the feature, some games may have some limitations. +We hope to slowly fix these over the course of the next few months. + +yuzu's Local Wireless Multiplayer was tested by our team of Testers and Support staff across a small set of popular titles. Their compatibility findings are as follows: + +{{< imgs "./compat.png| List of yuzu-tested multiplayer titles" >}} + + +## Screenshots + +{{< single-title-imgs + "Animal Crossing: New Horizons" + "./acnh1.jpg" + "./acnh2.png" +>}} + +{{< single-title-imgs + "Splatoon 2" + "./splatoon2_1.png" + "./splatoon2_3.png" + "./splatoon2_2.png" +>}} + +{{< single-title-imgs + "Mario Kart 8 Deluxe" + "./mk8d_1.png" + "./mk8d_2.png" +>}} + +{{< single-title-imgs + "Pokémon Legends: Arceus" + "./arceustrade1.png" + "./arceustrade2.png" + "./arceustrade3.png" +>}} + +{{< single-title-imgs + "Luigi's Mansion 3" + "./lm3_1.png" + "./lm3_2.png" +>}} + +{{< single-title-imgs + "Super Mario Smash Bros.

Poke, prod, and play! Please break this release if you can! With your help, we can make yuzu the best it can be. +Please reach out to us on our [Discord](https://discord.gg/u77vRWY) and report any bugs you find, so that we can quickly address them. + +That's all we have for now, until next time!
