SuperMartijn642s Core Lib Mod is a technical library created by the modder SuperMartijn642. It is used in most of their mods, which means that this technical mod must be installed along with the other mods. The mod itself does not add anything or change anything in the game, but it simplifies and speeds up the creation of other mods. It is loaded on demand.
Warning: Be careful, as the same author has another technical mod with a similar name – supermartijn642s config lib. In many cases, you will need to install both technical mods simultaneously for proper functionality.
