A universal mod loading system for Minecraft (specifically on servers), allowing mods to be loaded on clients which do not traditionally support mod loading (Lunar, Badlion, etc.).
It appears that a jar's META-INF directory can contain version specific files in the versions subdirectory. At the moment, this versioning is ignored, causing the loader to load files for more recent Java versions than it was compiled with, causing errors such as CoolSpy3/CSHypixelAPI#4 . It should be updated to ignore these files.
