Question about Neokey?

[raiden_9123]

I just purchased a PS2 and my serial number begins with U6.
I am not sure which version that is and I am not sure if it will work with the Neokey.

Can someone help me in determining what my options are?

Also, if a Neokey will work, which version of GameShark will I need?

Thanks

You have a version 4 PS2, A neo key will work ok but you will have to patch some of the games. You will also need a gameshark V1.4 or better.
