when i look in each ps3 game folder there is ps3 game and ps3 update, which in the update folder its a pup file. what is this can it update the ps3 firmware or does it only affect the game , i guess im asking if it could update system software if im not safe . i know w/ the 360 i always delete the update folder and w/ wii run iso through brickblocker b4 burning. just curious what it is thanks
