Welcome to kh-vids :)

They can be used on either the PS2 or for a PS2 emulator on the computer, but in order to use it on your PS2, you need to get a cheat disk, such as Action Replay MAX, Gameshark, or Codebreaker.

Do you have a North American copy of Kingdom Hearts 2? Depending on where you bought the game, it will have a different region, and you need to use codes that will fit that region. If your game was bought in Europe, or certain parts of South America, you need to use PAL codes (not NTSC/UC). It should say on the game's box and disk, either PAL or NTSC/UC; that's how you'll know for sure. If it says PAL, then use the codes in here:

If you need me to explain anything else, just ask :)
