SuperMartijn642s Core Lib Mod FAQ
10 questions players actually ask, answered.
What does SuperMartijn642's Core Lib actually do for me as a player?
Nothing on its own — it adds no items, blocks, or gameplay. It's a shared code library that other mods by the same author depend on, so you only notice it when it's missing or outdated.
How do I know if Core Lib is installed and working?
Check your mod list and confirm it appears alongside the mods that require it. If a dependent mod loads without a missing dependency error, Core Lib is doing its job.
A mod says it needs SuperMartijn642's Core Lib — where do I get it?
Install it from the same mod hosting platform you got the dependent mod from, matching your Minecraft version and mod loader. It must be present in the mods folder before the dependent mod will load.
Is Core Lib the same as SuperMartijn642's Config Lib?
No, they're two separate libraries by the same author. Many mods need both installed at the same time, so if one is missing you'll still get a dependency error even with the other present.
Why does my game crash on startup saying Core Lib is missing?
A mod you installed depends on Core Lib but it isn't in your mods folder, or the version doesn't match your game version. Add the correct Core Lib build for your Minecraft version and loader, then relaunch.
Do I need to update Core Lib when I update a mod that uses it?
Usually yes — dependent mods are often built against a newer Core Lib. If a mod fails to load or crashes after updating, update Core Lib to the matching version.
Can I remove Core Lib if I don't use any of the author's mods?
Yes, it's safe to remove if nothing depends on it. But if any installed mod lists it as a dependency, removing it will break those mods.
Does Core Lib affect performance or FPS?
It's a lightweight library with no world content, so it has minimal impact on its own. Any performance cost comes from the mods that use it, not from Core Lib itself.
Will Core Lib work on a server, or is it client-only?
It's typically required on both client and server when a dependent mod is installed on both. If the server runs a mod that needs it, install Core Lib server-side too, or players will get connection or loading errors.
Can I use Core Lib with other mod loaders or alongside unrelated mods?
Use the build made for your specific loader (Forge, NeoForge, or Fabric) and Minecraft version. It coexists fine with unrelated mods, since it only provides shared code for its dependents.
