Comment (by csnover):

 I think you’re confusing AR correction with the broken implementation of
 AR correction in ScummVM today.

 The only technical problem with AR correction right now is that the
 engines can’t communicate the correct PAR to OSystem, and criezy is
 working on this. The correct PAR for DreamWeb (and a few SCUMM game
 versions) is 1:1. The correct PAR for almost all the 320x200 VGA games—and
 this is where the aspect ratio correction functions correctly—is 5:6. The
 NES version of Maniac Mansion is different than both of these and has a
 PAR of something like 8:7. This isn’t a “pros and cons” thing, unless
 you’re talking about how low-DPI monitors can’t interpolate without
 visible smearing. By default, AR correction fixes more games than it
 breaks now, and once PAR is communicated, turning AR correction off will
 result in image distortion 100% of the time.
