I wrote it so many times in this forum, but I clearly remember:

the grappling hook scene - Luke missed for the first time, Leia kissed him, and then he tried it for the second time and was successful.
Luke meeting Biggs in the hangar before the Death Star battle was for me always there, and I thought they have actually made it SHORTER for the 1997 SE
during the briefing when Luke says he used to shoot womp rats from his T-16 to the other guy, they shake hands and introduce themselves. I remember he introduced himself as Wedge, it was weird to see that there’s another Wedge in the battle and this guy appears in any other scene

Were these scenes in the movie? I used to grow up with different high generation bootleg copies of different European prints, so originally I thought that maybe some European country has received a different cut or something like that, but they still can be only a part of my imagination. Why? Because I have absolutely no proof that they existed.

So yes, maybe the memory can play tricks on you. You can’t be 100% sure about anything what happened 4 decades ago unless you have a thing which can be considered a PROOF.
