> I would definitely be curious to know why - the emulation of Genesis is notably behind most other video game consoles but I always assumed this was because of less interest and not because of any unique technical challenges.
I guess it sort of depends on what you mean, but I don't think there are dramatic differences in emulation quality between the Genesis and other consoles of its generation. Admittedly, I am rather biased since I'm the author of one of those, but I think outside the add-ons Genesis emulation is in pretty good shape overall. Both Ares and BlastEm acquit themselves well on the most demanding demoscene prod[0] for the system and even Genesis Plus GX is fairly accurate for a more performance-focused emulator.
Now none of those are perfect and I think it would probably be fair to say that they are less-perfect than Higan is/was for the SNES (though it wasn't perfect either), but I don't think the delta is huge.
Now once you add the Sega CD and 32X things are definitely worse, but those combined systems are considerably more complicated to emulate than any of the base consoles of that era while also being much less popular.
