What the library covers
SuperMartijn642's Core Lib is a core library and API created by SuperMartijn642. The project falls under the Libraries & APIs category on Modrinth.
The mod provides shared foundational logic for other mods. Specifically, the author wrote basic implementations for guis, blocks, tile entities, and network packets. That approach keeps internal code consistent across different Minecraft releases. You'll usually install this file because another mod from the author requires it to run. It doesn't provide standalone tools, blocks, or gameplay mechanics directly to the player on its own.
Loader and version support
Loader choice matters when adding mods to your game. The Modrinth project lists official support for three loaders. Honestly, these are Neoforge, Fabric, and Quilt.
The structured record identifies several specific Minecraft releases. These are 26.3, 26.2, 26.1.2, 26.1.1, and 26.1. The data also explicitly lists 1.21.11, 1.21.10, 1.21.9, 1.21.8, and 1.21.7. In the project description, the author mentions writing code to unify development across Minecraft 1.12, 1.14, 1.15, 1.16, 1.17, 1.18, and 1.19. You must verify that your game edition matches an admitted build before launching your profile.
Side requirements and distribution permissions
The project requires installation on both sides of the game. It's marked as required for the client side and required for the server side. If you host a dedicated server, you must place the file into your server mod directory. Any player joining that server must also install it on their local game client. Omitting the file on either side will cause issues.
The project is licensed under an all rights reserved policy. Even so, the author includes an explicit permission statement in the project FAQ. You can freely include the mod inside your custom modpack without asking for special clearance.
For extra information and downloads, the linked repository points to CurseForge. The author also maintains an official SuperMartijn642 Discord server where players can follow upcoming mods and join project discussions.
