Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

No Moon Network Fix

This mod is a general performance improvement patch for no_moon.jar. Originally, this mod aimed to fix multiplayer peformance, but many bottlenecks for multiplayer performance also affect the singleplayer experience - so, if you play by yourself, your TPS should also improve.

This must be installed on the server (or on the game of the player hosting the multiplayer session).

A note for Dedicated Servers (i.e. Aternos, or any other place where no players host the game on their computer): I've seen reports of several Internal Server Errors. In version 0.0.4 I've added a patch for one of the issues. This should allow to join dedicated servers, but stability over long sessions and events may vary.

Incredible fix (ping before: 37s, ping after: 196ms)
