Comment (by spiffythedog):

 A few FM Towns games (most notably Last Crusade, Loom and Zak McKracken)
 also make use of smooth scrolling. This is especially evident in their
 introduction sequences:

 This lack of smooth scrolling in ScummVM also seems to be the reason why
 the visuals appear to run slightly out of sync with the redbook audio
 tracks, as documented here: [https://bugs.scummvm.org/ticket/9591]
