Yuzu/Citra本地多人联机模式(LDN)指南

CVN-Play

2022年9月10日，yuzu EA-2943更新LDN模式联机，并且支持玩家自建房间。这里和大家简单介绍下LDN模式的联机方法。

首先介绍下LDN模式，LDN 模式是 Nintendo Switch 上本地多人游戏（Local Wireless）的默认模式，支持附近NS之间的通信。后来由spacemeowx2开发的Nintendo Switch系统模块ldn_mitm，可用于在线联机支持局域网的游戏。它通过替换系统原有的ldn服务，利用UDP通信协议实现局域网内的设备发现与连接，避免了依赖WiFi服务的限制，让Switch在没有网络或WiFi信号弱的情况下也能顺利进行联机游戏。而模拟器对LDN的实现也得益于ldn_mitm项目的代码支持。模拟器有了LDN，无论是LAN还是WAN环境，都可以通过UDP通信协议实现Local Wireless游戏的联机。
由于目前LDN功能几乎停滞开发了，因此某些游戏可能会有一些限制，以下是目前LDN模式（Local Wireless）的游戏列表，仅供参考。

yuzu玩家想要建立联机房间有两种方法，下面详细说明一下它们的使用方法。

方法1-创建公共LDN房间

此方法需要~~注册yuzu账户和~~公网IP，网工小技巧 | 如何判断路由器WAN口IP是否为公网IP - 哔哩哔哩 (bilibili.com)

~~可在yuzu官网获取密钥，将获取的密钥填写至yuzu模拟器设置-通用-网络-令牌对话框中~~

由于不可抗拒原因，Yuzu和Citra团队的项目于2024年陆续被迫关停，官方的公共联机服务一同也下线，2025年CVN联机平台托管了国内的LDN公共联机服务供玩家免费使用，可下载通用LDN联机修复工具，该工具可使用于修复Citra和Yuzu以及基于Yuzu源代码的衍生项目Suyu、Sudachi、Torzu、Citron模拟器的公共联机功能并转接至国内托管的公共联机大厅。

然后点击Mutilplayer-Create Room输入房名等信息即可，此房间为公共房间，可以显示在公共服务器列表中让全互联网的玩家加入。

同时需要在路由器将运行yuzu的电脑IP联机端口（默认24872）映射到公网，这个不同品牌路由器方法不同，但基本一致，可自行百度。

此时小伙伴就可以加入你的房间了。此方法有个特点，就是房主的用户头像是和yuzu官方论坛账号头像一致。

方法2-创建私人LDN房间

此方法无需yuzu用户密钥，无需映射端口，可直接建房远程联机，但是无法显示在公共服务器列表中

如果是在同一真实局域网环境或者联机双方（多方）均为公网IP，可以直接开房联机。如果没有外网IP也想远程和小伙伴联机，可以配合CVN联机平台组建虚拟局域网实现LDN多人联机。

首先所有需要联机的玩家登录CVN联机平台，并且确保可以互ping，具体教程可参考STEAM？模拟器？怀旧游戏？支持各类游戏局域网联机的通用方案-CVN联机平台 - 哔哩哔哩 (bilibili.com)。

注意，CVN账号需付费购买，购买前可免费使用测试账号进行测试，使用过程中遇到问题可参考FAQ

CVN登录完毕后运行yuzu，模拟-设置-系统-网路-网络接口 选择CVN的虚拟网卡，注意该网卡命名不一定为以太网2，请自行辨别

然后点击Mutilplayer-Create Room输入房名等信息，需要注意的是右下角下拉选项中选择未列出

点击管理房间，此时私人房间已建立完毕，房主IP即为CVN分配的虚拟IP

其他CVN玩家加入该房间只需要点击Mutilplayer-Direct Connect to Room，然后输入房主的CVN平台IP和端口号即可联机
