Any up-to-date 3DS ripping tutorial?

[TheWeirdOtaku]

All the ones I've found seem to have dead links, outdated and/or missing information. I'm interested in ripping some weapons and stages from Kid Icarus: Uprising, I have the game digitally but I've broken my laptop to the point of it not being able to read SD cards.

I was just wondering if anyone had a tutorial that's at least sorta easy to follow?
