Frequently asked

Does Sophisticated Backpacks (Unoffical Fabric port) work on Minecraft 1.21.1?

Yes. 1.21.1 is the newest Minecraft version Sophisticated Backpacks (Unoffical Fabric port) 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 Sophisticated Backpacks (Unoffical Fabric port) support?

Everything the author has declared, from 1.19.2 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 Sophisticated Backpacks (Unoffical Fabric port) on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which platform or loader does Sophisticated Backpacks (Unoffical Fabric port) support?

Fabric. 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 Sophisticated Backpacks (Unoffical Fabric port)?

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 Sophisticated Backpacks (Unoffical Fabric port) under?

LGPL-3.0-only, 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 Sophisticated Backpacks (Unoffical Fabric port)?

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 Sophisticated Backpacks (Unoffical Fabric port) 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.
