I ripped all the PMF'S from Final Fantasy Crysis Core USA ISO
so i could playback any of the cut scenes at any time without playing the game.
IR SHELL is needed to playback PMF files, I don't know of any other way including a PC with multi codec pack even fails.

The PMF can be anywhere on the memory stick and play them with IR SHELL Directory view. Triangle returns to the menu. Have fun   ;D
