If so, all you have to do is put the UMD in the PSP, access the VSH Menu, change the USB mode to disc0:// and turn on USB mode. Connect your PSP to your computer and dang! You've got access to the ISO!
Drag and drop it to your desktop and then change the USB mode back to the memory card and plug in your USB cord so you can transfer the ISO file back over. Easy as that.
