Seems to me few if any people here have actually thoroughly used Windows 8, preferring to make generalised assumptions.
Let me put my five cents in regarding Kega Fusion: I have a laptop that came with Win8 preinstalled. Kega Fusion ran the same except in fullscreen mode it ran at 32 FPS, regardless of vsync settings on Intel GUI or the emulator itself. A fix exists, but it's certainly not one you would've figured out yourself. Whether you're running 8 or 8.1 is irrelevant for these kinds of issues of which I've seen a fair few with older programs etc. While not an emulator Total Annihilation for instance will not run at all without its community patch and even then is a compromise vs just having Windows 7 installed instead.
Anyway, Kega is not the most accurate emulator anymore, although it certainly works for the 95% of games. Running Genesis Plus GX via RetroArch will allow you to run non-butchered versions of Titan Overdrive among other things flawlessly once you get used to the UI.
