There is something to be said for purposefully not emulating a machine exactly. Some emulators use intelligent algorithms to increase the resolution of the graphics. Obviously that is not aiming for authenticity, but just to make it look good. Same could apply to sound, and we could add sample interpolation &c, and have all the Amiga games with all the original gameplay, but which look and sound BETTER than before.
And why not?
But different people like different things so we should have options. Not everybody still has a real Amiga anymore.
