[1030]

I just went to Wal-Mart and bought a new Game Shark for PS2 and it didn't have a sticker on the back saying which version it was so I went aheand and bought it anyway got home and was surprissed to see the Game Shark was on a DVD poped it in and tried to see which version it was but it didn't say well anyway glad to say it booted up my Backups no problem with my Neo 2.0.So my question is which version of the Game Shark is it and will it work with all of the PS2 modchips Neo 2.0,2.2, and 2.5 and all board versions????
