Thanks so much for your work AllTinker, this is brilliant!
I know some of the comments elsewhere may have left a bad taste in your mouth, but I really appreciate what you've done and the love you show for the game.
Would you be willing to release the tool you wrote to extract the audio and rebuild the resource.aud file? I'd love to use AI tools to further clean up the audio - I've got some really nice results working on files extracted using SCI Resource Viewer, but the game doesn't seem to have an override mechanism so I believe the only way to get the restored audio back into the game would be to recompress them (as losslessly as possible) and rebuild the resource.aud file. Do you think that's doable?
