GameShark Swap
 

OK, I just got a ntsc playstation 2 ( 1C ) and a gameshark ( 1.9v )
I put the gameshark in my playstation 2 and it says that the disc is not forrmatted.
So I went to gameshark.com and found out you need a update to use it.
The update will come in about 30 days....
THe Question is.....Can You Still Use The Swap Trick When You Have A 1C Playstation 2 with The 1.9v Gameshark?

I may be wrong on this one but i dont think it will work without the update disc.
