About this Mod
Retromod
Run mods built for older Minecraft versions on current ones.
Most compatibility layers move a mod between loaders. Retromod moves a mod between game
versions. A mod built for 1.20.1 can run on a current release without waiting for the author to
port it.
How it works
Drop Retromod in, put the old mod in retromod-input and launch. Retromod rewrites the mod's bytecode, remaps its names, repairs its mixins, and patches its loader metadata, then moves it
into mods
Works on Fabric, NeoForge, Quilt, and Forge.

Best results: content mods, quality-of-life mods, libraries, recipe viewers, and more.
Poor results: full list and the rules of thumb
A mod that loads is not always a mod that fully works. Test it before you build a world on it.

AI was used in the making of this mod to analyze and improve my code and uses IntelliJ IDEA AI features for some code.
Also, if you don't like AI, just dont use this mod, I cant make this without AI in the same amount of time for the same level of performance "If it works, Why complain?"
Qult support made possible by quilt being able to use Fabric mods.

Retromod 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 (26.2). You can switch loaders with one click in the panel.
Is Retromod compatible with fabric and forge and neoforge and quilt?
Retromod officially supports fabric, forge, neoforge, quilt for Minecraft 26.2, 26.2-rc-1, 26.1.2. 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 Retromod – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Retromod consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
