You need game genie and these cheats are probably preloaded when they release the update for it, which i saw is suppose to be this week. if you cant wait or dont plan on spending money on a cheat device, just use bruteforce to decrypt the save, find the right lines and replace them with what you have there. then encrypt again. viola.
Its a program for decrypting ps3 game saves. And really, all game genie is is a hex editor. so with bruteforce and a hex editor you essentially have the same program. game genie just can decrypt it for you.
