If you pirate you copy Batman looses his ability to glide. Which is game breaking. Quite possibly the best pirate protection plan I've ever heard, amounting to "fuck those guys!"
Best guess is that they stuck the code for gliding in with the code that checks if you're using a disk. But I have no experience whatsoever with programing so...>.>
I'm annoyed ever so slightly with it now, but I still love it
My fault anyways. I jumped right into HARD mode.
Still, when I press 'X', I want to move to the next guy... not jump up and down like a retarded bear... Oh god... now I can't get the image of a retarded bear jumping up and down out of my mind... LOL
