I downloaded the current version of Batocera, and for the most part, everything works like a charm! The version of python included does appear to be broken, though. You can see this easily by running:
python2 -c 'import random'
The effect is that many of the plugins in Kodi are un-runnable. Apparently the 2.7.13 version has this problem on many arm systems, and upgrading to 2.7.14-1 will fix it.
