[HGSS] SDAT Hacking/Custom Banks?

[Kurausukun]

I've been trying to get a custom SDAT working in HGSS for ages now... Basically I've recreated the entire SDAT using the SDK, and all of the stuff that was originally in the game works fine, but when I add an extra wavearc+bank and try to use it for an existing song, the song just doesn't play. I'm looking for someone who is well-versed in the way HGSS handles audio and SDATs, or even someone who can help me debug it myself--I've tried doing a memory watch, but I don't know the correct addresses to look for, nor do I know how the game loads the audio in the first place (I think I'd need a disassembly of the executable). Is anyone willing to offer some advice? Thanks in advance.
