I just had a thought about the Post-to-Miiverse feature in several 3DS games. I tried to use it in Tri Force Heroes and My Nintendo Picross: Twilight Princess but the game tries to connect to Miiverse first, which now causes an error message. Since some games (including those two) have Miiverse stamps, which you can only use when posting from those games themselves, it made me wonder if the screen where you compose your post / drawing is part of each game's ROM, or if it's an extension of the Miiverse app. And if it's part of a game's ROM, might it be possible to patch out the connecting-to-Miiverse process so that we could at least mess around with the stamps?
(In any event I'm trying to access the stamps from Picross. I tried by extracting the ROMFS contents but can't get the JTEX images properly converted.)
