It’s the only version on the iTunes store. Just search on itunes.
Ok, I could be mistaken in my above post. While it’s true that the SW and TESB ibooks were updated in 2018, I’m unable to find my original file backups from back in 2013 when they were initially released. I can only say that I remember both ibooks being near the 1.2 Gb file size mentioned on the iTunes store listing.
After investigation, I noticed that my PC was only downloading versions in the 600-700mb file size range for those two books, while the files on my iPad and mac book are both in the 1.1-1.2 Gb range. I figured that must be due to a difference between SD and HD video files, but after a little effort to move the mac files to my PC, I’ve compared the video files in each version, and they seem identical.
Unless someone backed up the v1.0 or v1.0.1 releases of TMO SW or TESB, it’d be difficult to say if they ever included HD video. It is certain that ROTJ has never been updated and the video files are 720p rather than 480p.
