I bought my real A500 back in 1987 and I never ever came onto a non-distorted copy of "The Faerytale Adventure".
Why is the Intro sound-distorted all the time? Every ADF I checked out is distorted. On real Amigas or the WinUAE it sounds the same.
Is the Original Release distorted as well? I don't know. Maybe one can tell, who own the original DD.
