Now if only you'd ditched the stupid praxis ring.
That would be impossible without resorting to footage from before the Special Edition, which I think looks a lot worse, or creating a brand new explosion which would be too much.
Out of curiousity, did you fix the Rebel Fanfare at the opening of the Battle of Yavin?
No I didn't.
Edited to add I've just been doing some research and it looks like I was mistaken about where this change was. Now I've had a chance to check it, I don't think it would be easy enough to fix. Using SE Laserdisc audio is fine for small changes, but I don't think I could paste it in seamlessly, and a 2.0 soundtrack wouldn't be enough to work from because the scene is sound effect heavy.
I suppose it's too late to grab a copy, but then, there's always the torrent release.
