If you have 1600x900 monitor i.e. the resolution will look stretched horizontally. The larry games don't allow you to adjust stuff like aspect, fullscreen, resolution, output etc... instead of regular dosbox it uses scummvm. Go to the scummvm config file for each game, change aspect_ratio=false to aspect_ratio=true then save file, now the games will look right. Use alt+enter to switch between full screen and window mode. LSL6 super vga version has a gogdosbox configurator, wonder why they didn't sport this format for lsl1-6vga.

The set originally was released using scummvm, but no LSL6 SVGA.

After enough of us complained they added LSL6 SVGA in on dosbox. This is because LSL6 SVGA does not work in scummVM yet.

Also for the most part the VGA games run more efficiently in dosbox, but they never bothered to change them over to dosbox.
