neokey sbox
 

I have tried to back up mmx 2002, wwf smackdown 2, and nfl blitz 2001, I have gameshark version 1.5 and neo key. I have been to many sites that show me how and i do what they say. But none of my backups work, can someone please help me, I don't know what to do?
I have used clone cd, cdrwin, and nero and i can't get any of the backups to work?
