I've read that it's possible to have Myst III run in a window, as opposed to fullscreen, through "slight edits" to the .exe file. Try as I may, I can't seem to find *what* those edits are though, and was curious if anyone knew what they may be. I'm on the CD version of the game.
My main reasoning for wanting a window is because I was considering streaming a semi-blind playthrough of it, and unless I capture from a secondary computer there doesn't seem to be a way to break out of the fullscreen Exile and be able to resume playing once it reloads.
(I've tried using d3dwindower, while it does put Exile in a window there's no picture and my mouse cursor freezes outside the window until I click, at which point Exile is no longer focused. Using dxwnd results in the game crashing before getting to the graphics select screen.)
I've read about ResidualVM, and if that's the only way to do it I can just use that.
