ok im going to get the gs2 for the ps2 v4 but i dont know about a mod chip. It seems to hard. Then I heard that I can use the gs2 w/o the modchip and play backup games. But I need to do certain methods, i think one of them is a knife method, can someone please tell me the best method and im trying to steer clear of dismantaling my ps2. So anyone help would be nice. Thanks bye!
P.S who is the most realible ps2 backup game seller.
