Mario 3D Land by Splashman at 10:39 AM EST on November 18, 2011
I think Mario 3D Land should clear any leftover doubt that the 3DS is capable of playing fully streamed music in decent quality. Some of the tracks are even taken directly from the Galaxy games.
Now if only the developments in the 3DS dumping scene could move a bit faster. Or have I missed something? All I know is that there's a file viewer so far: http://3dbrew.org/wiki/3DSExplorer
But... not ALL of Super Mario Galaxy's music is streamed. Infact, I'm pretty sure that tracks like "Blue Sky Athletics", which is one of the tracks in Super Mario 3D Land is not streamed.
Also, how long was it until the first 2SF rips were possible? As in how long, after the DS itself was released?
Whoops, my bad. I just compared the 3DL tracks to those from Galaxy. They sounded so similar because they have the same compositions, but they use very different instruments after all. Except Blue Sky Athletic, which was indeed sequenced to begin with in Galaxy. So now I'm not sure anymore about my streaming theory... but still, I'd imagine they recorded a live saxophone for the 3DL Main Theme.
I still don't understand why Nintendo doesn't just improve their sequenced formats... Recording real instruments, etc..
Streams are annoyingly large and lack the dynamics that can be put in in sequenced.(Although Mario Galaxy and Mario Kart uses streams quite well dynamically.)
