I am new here, but I spent quite a few hours digging into the archive of this forum, and I would like to say that you look like an exquisite community
Now, I am doing some research on GF, and I learned that the backgrounds of the game were pre-rendered 3D. I got hold of Scumm Revisited (which I learned about in the babbles this very fine society) and was amazed to see all these assets neatly lined up in a browser.
But beside sounds file, I could not make much sense of the rest. In particular I am not sure where are the backfrounds/backdrops of the game located.
If anyone here toyed with SCUMM Rvsd and located these assets, and how to rip/dump/extract/decompress them that would probably save me a lot of time.
