SignatureThere's not really a thread... or anything for that matter really about music hacking in Pokemon, save one page of two different threads in PC, and a couple here, but none of it specifically covering the whole process of 4th gen music replacement. I've ventured into it myself, and have gotten somewhere... but it's not nearly enough. If you want to help with figuring this out (more specifically for HGSS) then PM me.
I'm doing this whether people help or not....... But it'd be really nice to have a team
