[quote name='Ginger Junk']Anyone know of a list of compatible games in other regions?
I downloaded a few PSP games from Hong Kong and Japan back when they were doing the Welcome Back free games deal so I need to know if I should bother buying a memory card to create a Hong Kong and Japan account on my Vita.[/QUOTE]
It's not about what's compatible--I have Rival Schools on my Japanese PSN account and my Vita sees it fine, but it won't copy to my system as long as I have it set up through my US account. Worse, supposedly, Firmware 1.8 has removed the Vita's ability to have cards with different accounts, so unless you find someone who's confirmed that cards with different accounts can still be used, then I wouldn't even try.
