I accidentally found this, but I think it might help with listening to remixes for CE
I downloaded a new version of CT from gpemu.cjb.net to do more beta testing, but when I unzipped the file, it came up with a long list of things. I assume that each file in the 7z file is a different version of the game, and one of them was 'BS Chrono Trigger - Music Library (J).smc', and it's basically just a menu where you can play songs from the soundtrack... that one, however, is in japanese, but there's a 'BS Chrono Trigger - Music Library (J) [T-Eng].smc' which is in english
It seems like a really convenient way to be able to listen to remixed music, rather than going to the part of the game that plays it... I'm not exactly sure how to listen to remixed music in the first place, but is there a way to patch this instead of the actual game to listen to the music?
