You can call me handicapped alll you want but what in the hell does MCP stand for?
I'm not sure what it stands for, but I know it's some kind of modding API for Minecraft that is required to code Equivalent Exchange.
It's called MCP, Minecraft Coders Pack.
It decompiles and de-obfuscates all the code so it's easy to read and find out what functions do, and generally a large amount of mods use it because it would be a complete pain in the ass to figure out what all the code did yourself.
