There should not be any major changes. Mmm weird.

Thankyou, first question. Who was Raphael again? Link mentioned him while saying that both him and Irma left.
second question. What happened to Kentor at the start of the game? he was one of the villains that was shown that I don't think was shown in the rest of the game. Was he killed in that battle? Also do I have to move any files to transfer my save to the new version, or is it already set in local files?
Raphael is Link's best friend. He appears in his memories. He is the purple-haired guy killed by Thaneris in the ambush in the desert.
Indeed, Kentor was killed by Athel in the battle at the castle front. It's mentioned in the introduction of the game. The Hyrule Army lose because of Thaneris' intervention.
You must transfer all "Save" files to the "Data" folder of the updated version of the game. As a precaution, back up your original game files before making any moves.
