Explain why BlargSNES works with the 3DS. I was able to go on Miiverse with the software still going. Also, what meltdown on Miiverse?
That's easy to explain!
You're talking about homebrew.
Nintendo's software has never done that on the 3DS. There's only been those Ambassador games and they haven't let you do that. I'm not saying it's impossible per se, but that it's impossible with Nintendo's excellent emulation software.
Hell, the GBA games aren't even emulated, they're running on the 3DS directly, which is why GBA on 3DS VC is even more unlikely, since Nintendo obviously wants main menu functionality.
It's just not feasible, regardless of a homebrew app that can do it, Nintendo's VC with tailored emulators, save states, and other secret sauce can't. I don't like to talk about homebrew anyways.
Edit: I should add, that app may have saves states too, I dunno, but yeah, not happening.
