Hello, I'm new here and was just wondering how big of an update will I need to play PSO 2 on Vita after buying the deluxe edition? Will an 8gb memory card be enough?

Also, can I still play the game with a pre-owned cart (I understand the DLC has been used, but I don't think that will stop me from playing)

Sorry if these questions have already been answered, as was unable to find them.
