I have recently bough PS All Stars for the PS3 and took great pleasure in redeeming the cross buy free Vita copy. I am well aware that it has cross play functionality allowing you to play your Vita against PS3 players. There are many sites that say cross controller functionality is in the game where you effectively use you PS Vita as a dual shock 3 controller to play the game on the PS3 but I have yet to find out how to do this as the cross play on my Vita simply tells me to start up cross play software on my PS3 even when the game is started up.
My question is does this game definitely have cross controller or does it simply have cross play. If it does only have cross play is there a way to play my PS3 against my Vita whilst using the same PSN account on both devices as I would like to use my Vita as a third dual shock to play against others on my PS3.
