I had a game shark but it stopped working. 
I'm not gonna waste money on another.
Maybe I'll just look around for a mod chip.
Don't you know how to reset one of those?! Mine went funky once and this fixed it.
To do this hold down the L1 + L2 + R1 + R2 + START buttons while you restart your PS2 console with the GameShark2 Disc and Dongle inserted. You will either see a screen stating to "press X to reset to factory default settings" or the screen will automatically state "resetting to factory defaults".
