Cut Levels and Cutscenes in Mirror's Edge

The console retail builds of Mirror's Edge contain files of unused levels and cutscenes, including an in-game cutscene with Miller that was (presumably?) originally going to be used before it was replaced with the FMV cutscene. It's surprising these levels exist in retail builds and not the Feb 2008 PS3 dev prototype. They were however removed from the PC build. I've modded the PS3 ISO to include binds for launching these levels and to display debug information. There is otherwise no other mod performed to make this work.
