Ok to get this on my psp I need a ISO i can turn into EBOOT but when I downloaded if off this website its a .mdf file.
What the hell do I do to turn it into a ISO?

An .mdf file is a another sort of image file usually created by Alcohol 120%. You should be able to mount it using a program such as Daemon Tools then using another program to create a .iso image from that mounted image. You can convert the .mdf to .iso by using UltraISO or something.

I tried ultraiso already. Popstation calls it a invalid game id.

Hm, try another program then like MagicISO. Don't bother using it for anything else other than image converting though.

have the same prob too :(

don't convert images, it frequently doesn't work. Use the mounting method described by anandjones above. A good ISO creating program to use is ImgBurn, if you don't mind not having a 'do everything for you' wizard.
