Dependencies

What The MegaStormdeclares it needs, from the author’s own release metadata. A required one has to be installed alongside it or it will not load.

Frequently asked

Does The MegaStorm work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version The MegaStorm 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 The MegaStorm support?

Everything the author has declared, from 24w12a up to 1.21.1. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install The MegaStorm on the client or the server?

The server only. Players join with an ordinary Minecraft client and install nothing.

What does The MegaStorm need to run?

It declares Cobblemon and Cobblemon: Mega Showdown as required, so those have to be installed alongside it or it will not load. Each one is linked in the dependencies section above.

What licence is The MegaStorm under?

CC-BY-NC-ND-4.0, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install The MegaStorm?

Data packs install per world: put the downloaded file in that world's datapacks folder and run /reload, or add it when creating the world. No loader is involved. On a server, the world folder lives next to the server jar.

Where do I download The MegaStorm safely?

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

Works on the same versions

Ordered by how much of the recent Minecraft version coverage overlaps, not by popularity.

Details from Modrinth, where the author last updated it on 30 Oct 2026. We do not host files or republish descriptions. Available download links point to the author’s own release.
