Algus: Last time I downloaded these games, it used DOSbox rather than Scumm, just downloaded it and scumm says it can't find the game data. The dosbox versions worked perfectly with no issues any chance we can get those back?
The only method I know of is through GOG Galaxy:
Install the game(s).
Go to Games > Installed.
Right-click any of the Space Quest games.
Select Manage Installation > Configure…
Uncheck Auto-update.
Click Show more versions.
Select "Version – 11 years ago" (the oldest version listed).
Click OK.
The game will update, and you will now have the DOSBox version.
