well first thing are you using a US copy of the game? if not theres your reason.. other than that the only thing that would make it not show up is if you put it in the wrong spot..
game saves go in the PS3 Savedata folder if u need help check the kjb stickied thread i think it tells you how to copy saves in there
The following user thanked dose for this useful post:
i read how to do it on page 1 but am still a little confused. Do you load up these saves then play the last level and THEN do the restart thing ? how exactelly is this done because this game is not worth 4 playthroughs
