Ultimate Codes discs?

[Leechboy]

I was at my local EB today and saw these "Ultimate Codes" discs for PS2. They had a Kingdom Hearts/FFX one, GTA 3, GTAVC, Tekken 4 and Medal of honor. It says on the boxes that they give you infinite life, level select, infinite money ect. Does anyone have one of these discs? How do they work? I would like to know as much as I can before I drop $10 on the Kingdom Hearts one. Thanks

They are like stripped down gamesharks. You boot the disc, choose the cheats, then swap the Ultimate codes disc with the game. My advice, buy it, try it, you dont like it, take it back :)

You can return it?
