I decided to look for the music in the newly dumped S3D beta ROM. Here are the pointer locations. Music is in S2B pointer format. BF4C6-BF4DD: adds to B8000 BF4DE-BF4E9: adds to C0000 BF4EA-BF4FB: adds to C8000 BF4FC-BF684: adds to D0000 Many pointers lead into a huge bank of 00s, which makes me think that I might have done something wrong. Or maybe it's just a regular beta thing. But these do seem to be the right pointers.
