So, for personal reasons I want to create an archive of the current FTB Beta pack and a world that was created in MP so that at any time I can extract the rar, run it, and play in the world. I have the MP map moved over and loading in SP fine, but I can not figure out how to seperate the MC install from the launcher. Anyone have any suggestions? I am fine relying on the MC servers for authentication (if Mojang ever dies and those go down I am sure there will be workarounds). I would really like to decouple it from the FTB launcher though, and I have no idea where to even start there. Anyone have any idea how I would go about doing that?
