Since 1.18.1, Minecraft requires Java 17 or above to run. 1.17.1 requires Java 16 


This mod is client-only, installing it on a dedicated server does nothing.


When this mod is installed, it will add a few new things to the "Open to LAN" Gui, which then allows the user to start the LAN game on a specific port, and also provides an option to disable the "online mode".

In addition, it allows you to enable or disable PVP and set the maximum number of players.

Since version 1.9, if you are using the "offline mode", you can enable an option that prefers the UUID from Microsoft/Mojang where possible. This avoids loss of inventory contents when switching from online mode to offline mode.


Language support: English (en_us), French (fr_fr), Simplified Chinese (zh_cn), Brazilian Portuguese (pt_br)
