I’ve made a fork of Gargoyle here with the three Scott Adams-related interpreters from Spatterlight:
https://github.com/angstsmurf/garglk/tree/saga
More precisely, this adds the updated ScottFree for standard Scott Adams games, Plus for the SAGA Plus games, and TaylorMade for AdventureSoft UK games. Now you can try them out even if you don’t have a Mac. Of course you will have to build it yourself, unless there are working artifacts for your system under the Actions tab.
The main issue is that certain animations will hang Gargoyle. At least this happens at the very start of Rebel Planet and at the waterfall in Robin of Sherwood. Other animations will make typing slow and difficult.
Also, there is currently no way to access settings for things like colour palettes or slow vector drawing.
