I have no leads for you mate - though this thread may be of interest…
As well as this post by Earl on the subject - link - and a few follow-up posts in the thread on the subject too. They are from 2017 - and indicate that selutron stopped work on his Edit before it was finished. (Some example videos and WIP cuts intended for inclusion to the Edit can still be found on youtube here, apparently.)
Oh! He didn’t finish it? I thought he did and was just posting clips from it like how Adywan did.
