⬇ Download on CurseForgeThe author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
The Dupe Core is a coal-powered duplication machine designed for simplicity and flexibility.
Fueled by Blocks of Coal, it allows players to duplicate items according to configurable rules. Users can choose between two duplication modes: duplicating items one by one from a full stack, or duplicating a single item directly.
A whitelist system defines which items are eligible for duplication, ensuring balance and control.
All settings are adjustable via a .toml configuration file.
