Here's a great Android port of Cemu that seems to work really well!
It has graphics packs and supports mods!
https://github.com/SSimco/Cemu
Wind Waker HD/Twlight Princess HD tested for a bit and the quality was excellent on my phone. A solid 30fps for each. It even has motion controls, I think, which might help with the gyro puzzles. So maybe Android is a good bet, assuming SSimco keeps working on that port, also assuming there aren't any issues. I haven't encountered any yet.
I will test BOTW soonishly and report on how it runs.
