I'm interested in writing an addon to IC2, and I've used mcp to write a few small things in minecraft, but I have no clue how to get IC2 working with mcp.
I tried by putting all the files from the IC2 jar into my minecraft.jar, but when I run the forge install script I get the following error during Retroguard:
COM.rl.obf.classfile.ClassFileException: ClassNotFound forge/ITextureProvider
I'm currently using mcp 6.1, Industrialcraft 1.90, Modloader and ModloaderMP 1.2.4, Forge 2.0.0.67. Any help would be greatly appreciated so I can start working on my IC2 addon!
