So, on the v1.0 & v1.1 versions of "The Macintosh Demo Games CD", there's a non-interactive demo for Indiana Jones and the Fate of Atlantis. Here's a video recording of what it should do: https://www.youtube.com/watch?v=K6P8VSN4YA0
But, in ScummVM, it's somewhat playable and broken. In the demo's folder, there is a file called "INDYPLAY" & in the "Atlantis Demo" sub-folder, there's a copy called "INDYPLAY copy". From what I can gather by viewing the demo in Mini vMac & SheepShaver, those are the files that dictate the non-interactive/gameplay recording part of the demo.
I confirmed that the issue still exists in macosx-arm64-master-2db0e59a. Is there any chance that proper support for this demo could be added? I've attached a compressed .sit version of the demo's folder if that helps. You would need to set the game's path to the "Atlantis Demo" sub-folder and the Extra's path as the "Indiana Jones" root folder.
