The project is finished. Subtitles were a pain in the ass and I’m not sure they work properly (were wonky when I played the ISO on VLC but I still have to test the disc at home in a regular player)
I cut together a unrated audio track which sounds pretty good considering the source I used. There’s also a mono track as well as a Turkish and a Russian dub I found.
You can find the ISO along with cover art and disc art over at the star wars trilogy forums.
Thanks for your help Doc!
