[Cza102282]

I am wondering how to do the knife/cog method. The method in which you take off the disc tray cover and stick a knife in the cog to unlock the tray and then put your back up CD in after you have booted up with either game shark 2 or action replay 2. Does this method exist?? Where is the white cog?? SOMEONE PLEASE HELP?? Thanx
