For my dismay, I can't play the 3rd birthday nor FFIV CC. So I guess it's time to upgrade my PSP. So, I would like to ask you the following: 1 - Do I really need to upgrade my PSP? 2 - Is there a way to fix the ISOs, so I can play them in my current version? 3 - If I need to upgrade, what would you recommend me? I would prefer one that wouldn't require me to hack it each time I reboot it... Thank you for you time.
