Gameshark 1.9

[neongeon]

Hi guys my friend has an usb mod and as you know, needs a gameshark to play ps2 backups. We're in the US and went to a toyrus where they had a lotta gamesharks but none had version numbers on them. Now the original psx gamesharks toyrus had, did have the ver numbers on a small white sticker on the back. However there was nothing we could see denoting the ver number. I did see a copyright of date of "1996-2000" so I told my friend if it was the lastest ver shouldn't it at least say something like 1996-2001. He agreed and decided not to get it. We're going to try best buy next but what if their's is like the ones at toyrus? How do we find out the version number.
Thanks guys any help is greatly appreciated.
P.S. We also tried funcoland-gamestop.com and their's didn't have a ver number either. Of course it was the very last one on display.
