So, about a week ago I bought this console. It is an Anbernic RG552, a decent emulation machine. I chose this model to turn it into a portable Vircon32 because it fits my console so well. It has widescreen, good d-pad placement and can run both linux and android.
I had never coded for android, but I was able to build an android version of my retroarch core and import it into the console along with game roms and thumbnails. I'm quite pleased with the results, you can see the console running here:
EDIT: And now, thanks to the people at Discord, the core works not only on Android, but also on iOS/MacOS/tvOS.
