Hi everyone! I wanted to pass a message from eriktorbjorn himself (who, by the way, is unable to register to this forum since it appears there's an issue which prevents people receiving confirmation mails).
He recently merged a great feature which allows for disabling with a toggle some of the SCUMM improvements not found in the original interpreters. This can be done in the "Game Options" dialog (not in the global options dialog); you can find a list here https://wiki.scummvm.org/index.php?title=SCUMM/Game_Enhancements for details on what the setting covers now (for instance, the character spacing setting in Mac Indy3 has been incorporated into the toggle).
I personally find this very cool, this is a great way to have some cool enhancements while still being able to lend a hand to purists and let them play something closer to the original experience.
