Thanks for the info, everyone.
Yeah, Schorman’s I-VI was the one I was racking my brain trying to remember the name of.
As for the ‘97 versions, it sounds like we basically have a “4k97” for ANH and a “D+97” for RotJ, but the ‘97 ESB is basically in a Harmy-esque 720p form with some of the less obvious later changes still left in?
