Gameshark Compatibility Question
 

Heres my set up
Gameshark 2 version 1.9
PS2 Version 4
I have the case opened so that I can swap disks without pressing the eject button. Do I need to patch backups? Are there any special things I should be doing?

You should be getting a Duo2 se installed :) .
You will need a Original hi-TOC dvd game to double swap with to load dvd backups. I think some of the EA games may need patching but i'm not 100%positive. This way of playing backups sucks, You really should get a chip, obviously your not worried about screwing up the PS2 or you wouldnt be trying this method.
