there are practical reasons why [how tthe electron gun works is] important, whether it be lighgun idiosyncrasies or how the game "feels," This is always interesting to discuss because there are so many factors at play! To put it in less than a zillion words, The way a game "feels" in this context is essentially a function of input latency. The old-style "chasing the beam" hardware, plus a CRT display, equals something very close to a true zero lag environment. Here's a breakdown of the input lag in a modern environment, for contrast. These are all latencies that don't exist in something like, say, a Sega Genesis/Megadrive hooked up to a CRT: http://renderingpipeline.com/2013/09/measuring-input-latency/ http://renderingpipeline.com/2013/09/measuring-input-latency... In an ideal emulation situation, you could theoretically recreate something close to a zero-lag analog environment (in terms of latency) without necessarily simulating the path of the electron beam itself. Although, as the linked article implies, there are a lot of bits in the emulation stack that would need to be optimized for low latency. High refresh rate displays get you part of the way there "for free."
