Prince of Persia: Forgotten Sands (BLES00840) - Working PKG here!
I didn't see any working pkgs for the mentioned game, so here you are:
Install the pkg, and put ALL the game files to /dev_hdd0/z/PRINCE
This folder should have:
USRDIR (with everything except eboot.bin)
At the moment this is the only way to play this nice game (it tries to use a place in the memory that's in use by the payloads, so it can't run).
P.S.: Don't try to update the game with this pkg! It won't work, and you'll have a lot of work in restoring the game's original state!
