RetroPi is one of forks of the Raspian (Debian) Linux. It is one of the most popular Raspberry Pi emulation apps around.
Though it has been around for a few years, it has not been perfect with issues of incompatible drivers of their hardware graphics acceleration. It's been fixed for the most part a couple years ago (but I had forgotten about it and not accessed since then). Now RetrOrangePi comes complete with Emulation Station, RetroPi, Kodi under Armbian Linux (a version of Linux for Arm Systems similar to Raspbian for the Raspberry Pi. actually they are functionally the same). It will tun on most Orange Pi Systems with H2+, H3, H5, A20, A64 CPUs with the Mali (400/800) GPUs. That is basically anything from an Orange Pi Zero on up, preferably anything system with 1GB of RAM though 512MB will work as well.
I do not have the time to check it out now but will in the near future. Check out:
