How about title directories? Do you happen to know a database for title directories?I don't think there is, sorry :-( You could try formatting your console once more in the hope the encryption lines up again.
EG: "Nintendo 3DS\daef03417d3a0d67e4128dbc9f4a1cb9\14cf01023010a55d30303030001b534d\title"
Do you happen to know which folder, within title, secures data for StreetPass Plaza?
