i beat the game on normal to get used to it and then i beat it on difficult...both were fairly easy, so i was looking forward to authentic mode. i selected the first level but authentic difficulty was not unlocked. i check to make sure i had a silver star in every level and i did...except for the final cinematic which didnt(which was weird because it wasnt a playable level yet it still unlocked authentic mode). how the hell am i supposed to get authentic mode? i know at one point in the game i had chose a level instead of hitting continue in the main menu, but i dont think that would effect me getting authentic difficulty. someone please help cause i really wanna beat this game on authentic and unlock all the extras that i havent yet.
