Bundle Crafting Backport
Backports the new bundle recipe (1 leather + 1 string) to 1.20.1. Free Minecraft Java mod for 1.21, 1.21.1.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
This project backports the lodestone tweaks from version 1.21.5:
- Cheaper Recipe: 1 Leather + 1 String = 1 Bundle
- Updated Recipe Unlock: The recipe is now unlocked when you obtain leather or string
