this is no good to the latest playstation2. if you have just got a playstation2 the ps2 gameshark disk won't work. you will have to also get the upgrade disk ... . you do need the gameshark "memory card" thing to make the upgrade disk work. stuck between a rock and a hard place. well worth it other than you feel like you have been ripped off when you get it home and it doesn't work. then you can make it work if you are willing to spend just a little more money. the reason is the sony changed the format on newwer ps2 systems so the original ps2 gameshark disk won't work. that's why you need the upgrade disk. marketing you have got to love it.
