What's PSP ISO?

Seriously, what's PSP ISO? If you own a PSP you probably know what a PSP ISO is. Right? Or am I wrong?

I don't have the details about PSP ISO or other related information about this one. I also don't have download links for PSP ISO. It's illegal for me to offer download links for PSP ISO. I could however point you to sites where you could possibly find the information you are looking for. That's the best that I could do for now.

Just let me know if you want the links to PSP ISO. Or better yet, just google for it. hehehhe
