Sega's take on the “classic” system. Releasing on September 19th, 2019 for much of the world, the Genesis Mini's ZUIKI Z7213 SoC (1080p maximum output) and 256 MB of RAM is surely capable of emulating the Genesis and it's games. Of course, it can emulate many other systems too, if you hack/homebrew it. Sales figures are unknown, but are presumed to be “OK” as Japan is getting a 2nd one in October 2022.

Whether these emulators support operating systems for these consoles is unknown; it must be looked into further. Consoles without meaningful OSes are not included.
