It's definitely not too small. Allow me to quote myself from a different thread:
That's compressed. 3D World is 2.4 GB. Lots of examples like that. The actual installed game takes up a bit more than the download.

I have no idea what you are talking about. You said a 3DS card can't have a "a hour long movie saved on the cartridge", but of course it does.
I thought he meant user videos on the 3DS card, which is basically impossible.
Regardless, 1 hour at 240p? Less than 8 GB sure, 'shrug', not that there's ever going to be a 3DS game that hits that. 3DS is never going to get a game on an over 4GB card or download. It's simple economics. Yes, that's Youtube 240p btw, probably just as compressed too.
Cheaper? How much it costs to add a few more music tracks in the game? It is not like they have to compose new music. Melee was a 2002 game, there is no excuse for the 3DS version to have almost the same quantity of music as Melee. Not to mention Melee's music were mostly remixes/remasters, which doesn't seem to be the case for Smash 3DS.
Melee was a 2001 game, and yes there is. Even not adjusted for inflation the game was higher priced at launch. The Wii U version is going to have more music because it's on a high-capacity disc, there's no restraints, no need for compression, and quite frankly that's where the most money per copy is.
Why should they split it 50/50 and leave their most dedicated customers with only the same amount of music and content? I get that you're a 3DS-only user but I really don't care because it's not relevant, just your biases showing. The games are not equal, never have been. They don't work for free. Also it's pretty ignorant to say "It is not like they have to compose new music." when we saw loads of it in the Smash Direct alone, mainly new arrangements, for example, a new version of the Fairy Fountain music.
But I'm gonna ignore you before I say something that will get me warned. You're biased and have no idea what you're talking about, without a doubt.
