The main disconnect is how much buffering/pipelining there is of inputs and outputs on modern platforms. This affects native games just as much as emulators, but most people don't complain because they're used to it. Modern systems driving LCD TVs routinely hit total input latency of 5+ frames. Oddly enough, we might get the necessary stack enhancements for lower input latency thanks to VR development, since in VR it's associated with vertigo and motion sickness. It would be pretty funny if a VR headset turned out to be the best display for old-school 2D games.
