Hi. I had actually been thinking about a project like this myself for a looong time
Anyway, I have the tools set up to dump all the cutscenes directly to png and wavs, losslessly, if that might be of any assistance whatsoever
And I'm a sound engineer if that is needed.
Drop me a PM if this sounds interesting.
EDIT; AND I have very good knowledge of the game and it's inner workings, if that counts for anything.
