As I recently found out you can get full games off the playstation sote onto a memory stick, from ps3 to psp and then plug your ps3 in and take data. As it is possible why can't I find any places to download them for free. ANY BODY KNOW ANY

Because that is ILLEGAL. Its stealing.

Also I don't believe that the Playstation Network is actually connected to the internet (meaning there is no website you can go to from a computer to download the games) you have to connect via the PS3 only.

Also if it's anything like the PS3 games they can only be used by the device that downloads them so you can't transfer them to another PSP
