Need help with PSX ISOs in PSP

Hi guys... i'm having some problems here..
Firstly, my psp's current version is 2.73... I'm hoping to upgrade i to version 3.10 so i can play PSX games on it.. Any idea on how to do that?

I think that is the version... Also, what program should i use to create the 3 images from PSX Isos that you mentioned in your tutorial ?

CloneCD

G.C, i have another problem.. when i run the 3.10 oe upmaker, nothing happens... also beforehand, i tried to on the PSP while holidin the right shoulder button down and nothing happen also
