The Last of Us [BCUS98174]

If the save is from a real ps3 then you need to decrypt it with Brute Forcse SaveData.
Saves from a real PS3 are encrypted using console-unique idps and account private key (act.dat).

Just watch the video on The Last of Us by BSoD gaming on youtube, it explains how to go ingame although his settings aren't completely accurate.
Strict Mode isn't needed anymore and some other issues with the info in that video that I can't remember.
