ESB and ROTJ use the 1980 and 1983 ALTA’s, I believe, rather than their 1997 counterparts.
Wasn’t SW the only one that was changed for 1997? Which means, TESB SE and ROTJ SE should have the originals since they weren’t touched in 1997? It’s been awhile so I don’t remember anymore… Otherwise it doesn’t make sense that they would’ve scanned only the titles from different reels altogether.
