There’s a bunch of different versions.
Main one on the site is probably Harmy’s Despecialized (SW 2.7 (with help from towne32), ESB 2.0, ROTJ 2.5). There’s threads detailing those.
Those 3 have been made into nice Blurays by NJVC, there’s a big thread on that. And a thread about distributing those from solkap.

Then there’s the new 4k77 for SW. There’s a thread on that.
There’s the Silver Screen Edition of SW. And a Grindhouse of ESB (and the Dreamastered colour correction of that). And I think a ROTJ Grindhouse as well?
Thread’s on all of those too, I imagine.

Probably some other versions I’ve missed.

So maybe a first step is to go look at all those threads and decide which version(s) you want?
