Frequently asked

Does Radical Cobblemon Trainers API work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Radical Cobblemon Trainers API 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 platform or loader does Radical Cobblemon Trainers API support?

Fabric, NeoForge. 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 Radical Cobblemon Trainers API?

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.

What licence is Radical Cobblemon Trainers API under?

LicenseRef-MCOML, 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 Radical Cobblemon Trainers API?

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 Radical Cobblemon Trainers API 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. The download link goes to the source recorded for that release; verify the publisher, filename and checksum before running it.
