I'm pretty sure PSVita will do that out of the box. With 3DS' hardware, however, it's not possible.Zarxrax said:but most of all, I would simply want a movie playing app like moonshell, which can play h.264 videos at the system's full resolution.
But I would already be satisfied with a decent MPEG-4 (XviD/DivX) player. There was already one for DS (could menage only around 12 fps), so I believe it could be ported relatively easily, provided 3DS is hacked.
