OP updated to reflect a new release of ESB that is underway.
In short, it’s remastered using OohTeeDee’s 19SE regrade and D+80 but essentially unchanged in terms of content.
I no longer use Adywan footage save for the Emperor hologram scene.
Currently uploading some of the versions while encoding others, but this’ll be appearing in the usual places soon.
ANH is next, and may have more for me to tend to than the others.
