GameShark 2 video game enhancer for ps2

good used condition. it's not a game .I don't know what exactly this is supposed to do lol. but it found its way in my collection years ago. cleaning out my closet. I have a bunch of games taking up space. I want to possibly upgrade to a newer generation ( ps3, Xbox 360 on up) because I never had them growing up. I was fortunate and grateful enough to own a ps1, PS2, and original Xbox consoles.it was fun but it's time to move on. I would like these gone within the month if possible. make offer
