I have a modded 5.50 Prome-4 hacked psp with a 4 gb memory stick. I just purchased a new 8 gig earlier today and I want to know what I have to do to enable it to run iso files. This may be a noob question, but I just want to know how to get it to work so no negative comments please. I'm relatively new to this scene so all helpful comments would be appreciated. Thank you for all that help me :)
