I just got my iPega 9068 working again after some weirdness with the analogs and i was curious would phones and things like that be strong enough to support 3DNes and maybe the VR stuff via cardboard? Unity being on android should work fine so if there was a barrier it'd be more "would there be the hardware to run it" and "would you want to work on it?" (i understand if you wouldn't but i figured it'd be better to ask than not to ask)

Very good timing question on your part because i'm toying with an Android build on my phone right now :). I would say mid-range phones or higher are enough to play 3DNes. But of course between "enough to play" and "optimized experience" there is still a quite long way to go.
