I was using the GameShark 2 ver 4 on my flat PS2 last time, and it was OK. When i changed my console into Slim PS2, the GameShark doesn't work. My console read the GameShark, but when it show me the message to put in my game disc, it can't read the game. Anyone please help me!!

PS: Sorry for my poor English

We have found that the problem is because the laser that Sony used! Try using the diagnostic mode and see if that helps. If that does not work then you'll have to get your laser realigned!
