I learned recently the composer for 7th Saga (Norihiko Yamanuki/"Botatsu Beat") released a remix of the soundtrack on Bandcamp in 2023: https://bosatsubeat.bandcamp.com/album/the-7th-saga-soundtrack-composers-edition-album-2023

It's interesting hearing some of the remixed tracks with added instrumentation and effects. Mix quality seems really all over. Sadly, I'm not so sure of "We are careful not to disrupt the worldview of Super NES". I think the SNES soundtrack is a case of "less is more" and these arrangements lose some of that charm. Still, neat to find.
