I've always had lower end hardware than my peers (still do, except at work!) so maybe you had a different experience than I did... But here goes my experience: Emulators are much harder to play than the original console because milliseconds matter! Maybe not so much for puzzle games (like the Zelda franchise)[0] but certainly for action titles... I don't know much about this "RetroPie", but it sounds like a raspberry…

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…

Found the source of 90~% of the latency.

1A current in a standard 10 gauge wire has a drift velocity of 23m/s, the wave propagation is dependant on quite a few other factors. The SNES controller is on a 20mA loop, with short to ground IIRC and the wire is likely to be 18 or 20 gauge, the velocity is still not nearly as high as you think, since the loop is interrupted you also have a delay on the sense line. Overall a 30ft cable adds about 2-3ms of latency t…

Drift velocity is unrelated to signal propagation. Otherwise it'd take entire days for packets to cross the country to get to you, which is clearly not the case. If we want to take an analogy, signal propagation is like a sound wave in the electromagnetic field inside the conductor; in real air, the speed of sound is clearly faster than the wind.

I love when HN users give such simple, real world analogies that are so easy to visualize or relate to. For those of us from completely different fields, it really does nail down the concept. always appreciated :)

> The controller ports aren’t as satisfyingly analog-feeling as the old ones, but that’s really not a big deal. It's slightly ironic that the author says this, since there is absolutely nothing analog about NES controllers -- they're nothing more than a shift register internally. By contrast, modern controllers do in fact have analog input mechanisms (although they are of course communicated with digitally). It seems…

To me "analog" vs. "digital" was analogous to "continuous" vs. "discrete". I would never have called an NES controller "analog".

Analog (as in continuous) was the holy grail back then. I was blown away the first time I got to try a real analog stick for a flight sim.
