Sharing Stuff from Tomodachi Life Online?

[Redeemer]

Hey guys, I wrote a song about SFO on Tomodachi Life and I wanted to show you but I don't know how to upload stuff from my 3DS onto the internet. Any ideas?

I have some other songs that are generally inappropriate (but not rule-breaking) and I'm certain they're worth sharing.

I know you can share Miis in Tomodachi Life with QR codes, but I don't know how to do it since I don't have the game. :c

You could use a capture card/video camera or some way to film it. I don't think there are any ways to share songs that you make on there.

Where can I find a capture card and how do I use it??

They are not usually mass produced, so you would have to find a website that sells custom 3DS capture cards. From what I can see, they are pretty expensive.
