GS2 problems

[nekromansur]

Just yesterday I received my Gameshark 2 and I wanted to see if I could play backup games. I have it all set up and everything, but the problem is that 1. I get these Disc Read Errors some of the times when I try to load it up. I have tried to fix these by following these instructions. 2. When I get to the part where it tells me to swap discs, I move the little white tab over, pull out the drive, pop the disc in, slide it in, pull the white tab back over, press X but then the screen either goes black for a second, then goes to the 'browser' where you can choose your mem card or your cd, or it just crashes at the loading screen. If anyone has any help as to why these dont work properly, I would appreciate it. By the way, I first tried using cheap discs, then I used a memorex and thats where it crashes at the loading screen.
Thanks
