Gamenative is absolutely sick but Android is also a PITA for handhelds these days. The kernels are always dated, the task management sucks, the UX sucks, and everything has to be ported into an APK with cruddy Android API mappings.

I have Rocknix dual boot on my AYN Thor, and it is so much easier to run native emulators on linux then to run the Android counterparts, which are guaranteed to be missing features or are out of date with upstream releases.
