Thanks Lars, for sharing this... I've been able to get a debug mode in EcoQuest 2, LSL 6 & Laura Bow 2... I've also seen the feature writer/polyeditor etc., they're in the later SCI11 games (KQ6, FPFP, etc.) and really extensive... However, SQ4 still didn't work, so there's probably another way of activating the debug mode in that game...
