Would it even be possible? There is a project Retropie On The Nano, but I think it hasn’t been maintained in over a year or so, and they claim it has bugs.
Could the Jetson Nano perhaps run EmuElec if android was flashed on it? It has a different CPU and GPU type so maybe it isn’t possible.
It would be very cool cause the Jetson Nano GPU is like 1000 Mhz or so, and it would run 3D much faster than the Mali’s.
