content-backport

by juanmuscaria

Players on a NeoForge 1.21.1 world who want content from newer Minecraft versions can use content-backport, which ports that content back to 1.21.1.

What it does

content-backport brings content from newer Minecraft versions back to 1.21.1 on NeoForge. The author states that the backported content is built from Mojang's own code, adapted to 1.21.1 wherever that is possible, so the result stays close to the original. The mod was first made for a friend's server, because most backport mods the author found were either poorly made or barely used.

Every player and the server need a copy of the mod. Files are published for NeoForge only, and the only game version covered is 1.21.1. The latest file is 1.5, released 2026-06-05, after the first release on 2026-05-13. The code is released under All rights reserved and is not open source.

Key features

  1. Backported content

    Content from newer versions is ported to 1.21.1 with high fidelity to the original design.

  2. Wandering trader offers

    The wandering trader sells some of the backported items, so they can be obtained in play.

  3. Message-based backports

    Some backported content is reached through a direct message, which the player can use to get the item.

  4. Worldgen settings

    New world generation settings are added, and they can be applied to a world that already exists.

Questions

Can content-backport be added to an existing world?

Yes. The new world generation settings can be applied to a world that was already created.

What the author says

I originally created this mod for a friend's server because nearly every backport mod was either bad, or used MCreator. This most is pure distilled Mojang code, mixed and adapted to 1.21.1 whenever possible. I'm deciding to publish this mod now before it rots forever in my HDD. Won't be publishing it as open source…
