That does help. Just be sure to match the names up properly and place them in the stream folder.i have a romfs extraction from acnl (i think it was before the update) if that helps at all?
EDit: would i just need to rename them to STRM_BGM_*name its called*?
That would be helpful. I'll help out with a list too, if I can find the time.I'll try to help with that once I organize. I'm familiar with some of the themes and the bgm of new leaf is available on smashcustom music so it might match up with most of the listed tracks in the document. I'll try to make a list with things matched up.
