How to back up a PSP Game to ISO format

This tutorial is how to back up your PSP UMD games.

First you will need a PSP with M33 Custom firmware. Dont have custom firmware? go get it,

Firstly insert your UMD disk you want to back up to an ISO in your UMD drive of your PSP. Turn on your PSP (if not on) Now hit select or home button to bring up your M33 VSH Menu and select the following:

* USB DEVICE: UMD Disc
* UMD ISO MODE: Normal

Once you have selected the M33 VSH menu as above, exit the VSH menu. In your PSP Menu Go to settings USB Mode. Now connect a USB cable to your PSP and connect this to your PC (sorry macs are not supported)

Depending on your PSP it will say Installing drivers this is normal under vista. Go your computer and you should now see a Drive logo with the ID of the UMD. In my case for GTA Vice City Stories its ULES-00502. Open this and you will see some thing like ULES-00502.iso. This is your ISO back image of your UMD Disk. Copy this to your computer. I recommend you rename this iso to the games name for easy of use.
