That raises an interesting question as the things that need changing are indeed no different from any mod. All you do is unlock the campaigns manually. The guys who came up with it also uncovered intersting tec-stuff related to campaigns and missions in general, yet we can't talk about it because it can also be used in the pirated version(like any other mod).
