Could this work,booting backups on the ps2 without modchip?
 

I read a post At vcdhelp.com in the dvd player hack section and i went to a post about the ps2 some guy wrote that if you press O= 18 times,R1= 5 times, and L1= 5 times at the browser configuration screen you can boot a backup game?

I think it's crap!!!

it has to be during full moon, and you have to dance naked on the street during it too.

of course it's bullshit.
