About this Mod

This mod adds all discs added after the version you download for into the game. This is a great mod for any music disc lovers that want the 1.21 music discs but are bound to 1.20.1 due to the semi-discontinuation of forge modloader. Later versions will be realeased for 1.19 and 1.18, but currently only 1.20.1 in supported, as I am working on a massive update for my main mod, More Discs (This will be coming to Modrinth when the update is done, beta version on Curseforge). This mod is basically vanilla and is a great addon to your modpacks without making the game feel overly-modded.

Frequently Asked Questions

Disc Backport server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.6). You can switch loaders with one click in the panel.

Disc Backport officially supports fabric, forge for Minecraft 1.21.6, 1.21.5, 1.20.6. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Disc Backport – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Disc Backport consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
