Despite the 'forcing' aspect, I have to disagree with that to some extent. Sure, the OPL synth is not what Prince composed
Doom's music on or for, but that's the way most old-school Doomers first heard them. If you were to seat someone who played the original shareware in 1993 at a station playing the
Doom tunes via SoundCanvas and then at one playing them via OPL, the latter is much more likely to provoke an "Oooh, that brings back memories"-type response. Nostalgia here lies in the ear of the beholder, not the composer.
Additionally, I think it's important to note that as
Doom fans, our view of the original game is always and forever will be skewed by the way it was. Sure, the game we know turned out much different from the
Doom Bible's original spec, but that doesn't mean that one who wants to experience it 'old school' by, say, turning down the resolution is 'misguided' at all. If that's how they view "the way it would've been" in their mind, then so be it. Not that all of us would care about that, mind you, but the ones who do will most likely see it that way.
