I know somebody knows how to do this......plz help!!
 

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

Madness. This is what you are considering to do:

1 Rip off the front plate of the disk tray

2 Shove in a knife at the right moment

3 Find the right spot - the 'clit' so to say

4 Hope that you lovely PS2 lasts for a long time

so you are saying this method doesn't work??
Shed some more light please....

Yes it works but at the risk of breaking the PS2.

nice one charlie
