I will try if I have time tomorrow... however the game is out in two days, and will have a proper sound test (which the demo hav'nt).
So far in the demo I heard:
- Battlefield (from the regular Battlefield arena, inpossible to rip without sfx in the demo);
- Menus tracks: At least 3 versions of it, come out at random when you navigate the main menu and the help/achievement menu back and forth; Those menu tracks are variations of the new main theme (exactly the same as Brawl).
Edit: Oh, it's only the same track; I've been fooled! Because 1/ the loop is very long (2 minutes for a menu music); 2/ it starts at random within the track when going back to the main menu!
Ripping right now.
- The help/achievements menu music.
- Result screen: Which is one of the original SSB menu theme arrangement.
- There is a how to play music with sfx when you don't use the game for one minute or two on the title screen (impossible without sfx in the demo).
- And the 3DS jingle from the dashboard.
Regarding rips from the game files, it will not be possible as the current method allow only games requiring 3DS firmware <7.0 to be ripped.
Edit again: Not first but did it anyway, enjoy:

Final edit (I hope): Enjoy!

~16Mo containing two Menus, jingle and results. Tried to do fast. I compared to some other guys menu rips on youtube and mine seems better quality I believe. Just tell me what you think, I will be back for the Zelda tracks on saturday! :)
