Man that is too cool and just finished up the 2nd Palace...about how long does it general take to set everything up on the Vita/TV ?

Hacking the vita itself takes mere seconds. Afterwards, FTP/moving files to USB really only takes as long as file transfers need to, and you're all set. With a good walkthrough, you could be playing a PSP game in 30m of setup
