1st... Thank you for insulting the site and staff, I really appreciate it, really I do... 2nd... If you had suggestions for improvement of the organization, you can always let a staff member know. But hey, what ever... 3rd... All MSPD (Memory Stick Pro Duo) work with PSPs right out of the box, except for the fake ones (which most times aren't formatted right, and never will be. Causing the failures), but I personally format every one with my PSP, since that almost guarantees that they will work, it's just like installing a new hard drive in a PC, you can either trust that the factory has formatted it right, or you can take the couple of minutes of you time and do it yourself... Now if I sound a bit terse tonight then that would be because I have just gotten out of a bar fight trying to help a buddy, and my adrenaline is flowing just a bit... So I apologize for the untempered-ness of my initial reply...
