Okay, I'm sorry, I thought my save file was 100% but it's only 98%. It was the Xbox 360 version that I completed 100%.
It seems to be only missing a couple of the hidden case files. Unfortunately, unlocking all of the movies requires beating the game 3 times, fighting the main bosses in a different order each time.
I put instructions for both JKSM and Checkpoint in the .zip file.
