I am playing Solatorobo: Red the Hunter (which is a DS title) on my 3DS, and I often just shut the 3DS while I am walking around (thus suspending the game).
It seems, however, that I never manage to pick people up via StreetPass while I have a DS game suspended in my 3DS.
Is this actually the case? Is there something about suspending a DS game that prevents StreetPass from working? Or have I just been unlucky?
Best Answer
No - StreetPass will not work if a (regular) DS title is suspended.
StreetPass will definitely occur if a 3DS title is suspended with the system on, closed, and transmitting wireless. (I've had this happen with Ocarina of Time.)
StreetPass will also often work when the system is open and you're actively playing. I've had this occur many many times when using StreetPass Mii Plaza (Plaza and Find Mii II), and even in Street Fighter IV 3D.
