Black Rock Shooter is out however despite the fact that it's released on US and UK Playstation Network Stores it's not available in Australia, I messaged NISA and they repplied
I regret to inform you that Black Rock Shooter: The Game is not available as an Australian SKU. This is due to licensing restrictions coming from Japan.
this means i am now forced to get the game from another store, i know with the PSVita, the memory card you use gets locked to the store you open it with which in my case an Australian one
For a PSP however, i already have a memory card which i logged into my Australian PSN Account with which is my main card, i'm wondering if i need to use a separate card to access the UK Playstation Network Store cause with the PS3, you can't access 2 accounts on 1 profile, you have to create another profile in order to access another account (which is why i have 3, my main one, one for the UK STore and one for the US Store) and the PSP doesn't have the functionality to create different profiles on it
