The sampling technique is another thing altogether, as well as the true-to-life circuit path. The closer you model the small things, the closer the whole thing is to it's real-life counterpart, but the time you invest in it seems to increase exponentially once you get into that much detail.
Also, I kind of disagree to a point with the notion of not making remakes 100% true to life. I think if you're really trying to make an emulation, you try to make it as much as possible like what it's intended to replace, otherwise it's really just a knockoff inspired by . . .
But anyways, cheers to the notion, real emulations are charming to play around with regardless, especially when a real one costs more than a house.
