Frequently asked

Does Insane's Survival Overhaul (aka IguanaTweaks Reborn) work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Insane's Survival Overhaul (aka IguanaTweaks Reborn) 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 Minecraft versions does Insane's Survival Overhaul (aka IguanaTweaks Reborn) support?

Everything the author has declared, from 1.10 up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Which platform or loader does Insane's Survival Overhaul (aka IguanaTweaks Reborn) support?

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

Which Java version do I need for Insane's Survival Overhaul (aka IguanaTweaks Reborn)?

On the newest Minecraft version it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the mod itself, so on an older supported Minecraft the answer is that version's Java, not this one.

How do I install Insane's Survival Overhaul (aka IguanaTweaks Reborn)?

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 Insane's Survival Overhaul (aka IguanaTweaks Reborn) safely?

Start with the author's page on CurseForge, which is where the data here is synced from. MCReference does not host or repackage files. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
