Multiplayer Mods

MultiMC Zip Method
If the server is on a modded multiplayer version, the download link to the mod is on the Downloads page. It is recommended to use a MultiMC-adjacent launcher for these mods. There would be two download links, one for a MultiMC instance, and another for the Jar itself. Only use the Jar if you know what you are doing.


 * 1) To use the MultiMC instance, drag the zip file into your instances window. That should import the instance. If this doesn't work, click "create new instance", then click "import from zip". From there you can browse your drive for the zip file.
 * 2) Right-click on the instance and press edit instance.
 * 3) Go to settings and make sure that the java path is correct for your system.

You can now launch the game.


 * For classic versions there is no fullscreen so you will need to manually edit window resolution under the "Game Windows" tab.

Jars/Jarmods
You can also use the Jar file or jarmod yourself. Warning, only do this if you know what you are doing. If you are using MultiMC or Codex-ipsa client, select the closest version to the multiplayer mod version and use replace jar for jar files and add to jar for jarmods. In Betacraft, move the jar file into the versions folder and with jarmods do the same but move the jarmod into the vanilla jar for its version. Also make sure to use the Betacraft proxy: ``-Dhttp.proxyHost=betacraft.uk -Djava.util.Arrays.useLegacyMergeSort=true``. You can download the Jars/Jarmods here!
