Installation

Two Fabric jars are published, one per supported Minecraft version — pick the one matching your game version.

Fabric (primary platform)

Jar Minecraft Fabric Loader Fabric API Java
multicore-magic-fabric-26.2-*.jar 26.2 >= 0.18.4 any 26.2 build 25
multicore-magic-fabric-26.1-*.jar 26.1.2 >= 0.18.4 any 26.1.2 build 25

Mod Menu and Cloth Config are not required — the mod works fine without them via /multicoremagic commands. They're only needed for the in-game settings screen.

Steps

  1. Install Fabric Loader for your Minecraft version (26.2 or 26.1.2).
  2. Download Fabric API matching that same version and place the jar in your mods folder.
  3. (Optional, for the config screen) download Mod Menu and Cloth Config for that version, also into mods.
  4. Download the matching multicore-magic-fabric-*.jar from the Releases page and place it in mods alongside the above.
  5. Launch the game with the Fabric profile.

NeoForge (via Launchpad)

Both Fabric jars also run on NeoForge through Launchpad — a tool that loads Fabric-format mods directly from their fabric.mod.json on NeoForge, with no separate build or code changes needed. This mod opts in via a launchpad:compatible metadata flag.

Important

Launchpad currently only has builds for Minecraft 26.1.2 — there is no 26.2 release yet. Use the fabric-26.1 jar with Launchpad on NeoForge 26.1.2. The fabric-26.2 jar is ready for NeoForge the moment Launchpad releases a matching build, but genuinely cannot be loaded on NeoForge 26.2 today. Check Launchpad's releases for current status.

To use this on NeoForge 26.1.2 today, you'll need:

The Mod Menu config screen is not available on NeoForge (Mod Menu itself is Fabric-only, and isn't ported by Launchpad) — use the /multicoremagic commands instead, which work identically on both loaders.

Verifying it's working

Run /multicoremagic status in-game. You should see something like:

Multicore Magic: enabled | threads=7 active=2 queued=0

See Usage for what these fields mean.
