The idea with the Sidious reveal was to have the lights flicker out when he starts to use the force lightning, then come back on to reveal a monster face when it dissipates. Kerr was the first to use the idea, and L8wrtr used it too. It's not perfect, but it helps do away with a lot of crummy dialogue during that scene. More importantly, it gets rid of the idea that he was injured by his own force lightning. He says this later, but this version makes it clear he's lying. Episode III should have featured a gradually aging Palpatine, like Episode II did. This solution, I feel, is better than what we got in ROTS.

The Darth Vader "Nooo" scene had to stay in this edit. Given what I was doing with Padme and changing who knows what about whom, this scene sets things straight. It establishes that Vader believes Padme is dead, that Palpatine lies to Vader about her, etc. I did try to use the "Nooo" from the 2011 edition of Return Of The Jedi, but I couldn't make it work. The music was too powerful in the clip, and there's reverb of the existing "nooo" in most channels. I never really minded that moment too much, though it is cliche and un-Vader-like. What are ya gonna do? If this edit didn't alter Padme's fate, I'd probably do what L8wrtr did and have the scene fade to black after Vader answers, "Yes, Master."

EDIT: The best way to get the edit at this point is myspleen. PM me for an invite; I still have a few left. Or you can try the fanedit.info site for a .dlc file.
