Well, no, I'm totally useless with audio. But the mono mix is there.

But I think it would be a nice idea (as someone here already suggested) if one of the sound guys made a nice 5.1 mix that would have all the mono mix sound choices. But I'm definitely not the right guy to attempt something like that.

Harmy, my ANH:Revisited 5.1 track has most of the mono mix dialogue, so that might be useful for you. I don;t think any sound effects were added in the places these lines were replaced
