well the wii u is actually an android phone with the wii u emulator on it.
I mean that the wii u actually uses the android operating system to some point.
So if we (and by we i mean i will probably do all the work) manage to boot up our phone/tablet with the wii u operating system the phone is actually going to boot up running it (with lots of lag).
But the only problem is that we will need a high end device to be able to boot up the phone without it crashing.
So the wii operating system has been known to be ported to wii u, so that means we can run the ported version on our phones/tablets. But its going to need lots of processing power and maybe lots of battery power and is not worth the hasstle.
But i have tried to do so and failed because my xoom is not fast enough.
