:| Likely not for while considering the 3DS' relatively short lifetime.
Also comparing something like the N64 to the 3DS is sort of an apt comparison to me for a couple reasons:
1. The 3DS is a handheld while the N64 is a console. And traditionally, being that consoles hold more vague similarities with PCs than handhelds, they are most of the time much easier to work with than handhelds.
2. The N64 and the 3DS are several console generations apart. It's no surprise that technology is constantly evolving and growing complex. It's no exaggeration that the 3DS is many leagues ahead of the N64 in terms of hardware. Comparing the two is difficult because they do not match technologically.
3. Console emulation is not a universal wave. The pretty picture of emulating is that every console game will come flooding into PC the moment that said console generation is over. This is simply not true. Different console get emulated at different times, some take a few months, some take a few years, and a spare few take several console generations. Some consoles can't even get emulated at all, take the original Xbox which to this day has not had a successful and fine tuned emulator while in contrast the PS2, a console released at the same time, which had a emulator developed a short time later.
4. Nintendo has arguably gotten more protective of its property in recent years. It doesn't take a historian to see that a lot of mediocre third party games and absolute crap was easily released in the N64 and previous console generations (take one good look at retro video game reviewers such as AVGN and JonTron for proof). While I'm not saying that current consoles are immune to crap, be it games or gamers (I've seen my fair share), I am implying that corporations (Sony, Microsoft, Nintendo) are much more careful and protective of their big black boxes than in the past.
I'm not saying a 3DS emulation is impossible. I saying that too much is in the way of an emulation happening in the near future with all the varying and occasionally incompatible technology, hawk-eyed and ruthless corporations, and the continuous changes in the gaming industry.
But that's just one man's two cents
