There's been some work to get Android Marshmallow running on the Raspberry 2 & 3. Right now they are focusing on the Pi 3.
They've been able to get it to use all of the CPU cores and I believe they have been able to get GPU acceleration working.

I haven't tested it yet to see how responsive it is. There's some videos on YouTube that does some demos of it.
Not sure how games like Artemis or Empty Epsilon will run on these builds. If I have some spare time this weekend at the convention, I will give it a go. Might be able to do some play testing on the second bridge if it works well enough.
Hopefully this will open up some more possibilities for in-expensive hardware to be able to run existing BridgeSims.
