Help ripping music from a 3DS file I downloaded?

I hope this is the right section for this…
Can somebody help me rip music from a 3DS file that I have or at least guide me how to do so? I don’t know how to rip the music at the highest quality nor do I likely have the right system for it.

I downloaded the files from a sharing site. The zip file included a .3ds file, a .nfo file, and a .sfv file. I’ve searched the internet, but I’m not savvy enough with game roms and such. I have no idea where to even start.
I run a Mac which I know makes it even more difficult since a lot of any results I found required a Windows.

I’d really like to make a soundtrack from it.

Thanks for any help!!
