Frequently asked

Does EXTREME CORE work on Minecraft 1.20.1?

Yes. 1.20.1 is the newest Minecraft version EXTREME CORE declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which loader does EXTREME CORE need?

Forge. A build for one loader will not load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for EXTREME CORE?

Java 17 or newer, because that is what the newest Minecraft release it supports requires. The requirement comes from the game rather than from the mod itself.

How do I install EXTREME CORE?

Install the matching loader first, then put the downloaded file in your mods folder and start the game. The loader, the mod and Minecraft all have to be on the same version, which is the usual reason a mod does not appear in game.

Where do I download EXTREME CORE safely?

From the author's own page on CurseForge, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
