FWIW, the stuff you're listing (MegaTech, PlayChoice, SNES bootlegs) *was* in my build.
For the rest, I repeat, it's only a matter of personal choices. As I said, we're going to see pacman arcade played on smartphones so I'm not surprised that there are people that play Atari 2600 Pitfall II in arcade cabinets. If it's fine for them, it's fine for me too.
My post was only a general hint. After all, also play Black Tiger with a PC and an LCD monitor is "retro-madness"..... But all of us, I guess, do it.
