Well, might as well tell the whole story.
I recently got Age of Conan, and at the start of the game there are a number of intro screens. I find them rather annoying and would like to remove them. But the problem is the launcher checks for certain files, if they are not there they get redownloaded. It also does a hash check on them.
So is there anyway to spoof a hash check, on some random file so I can replace the rather large in size videos with them.
