I don't think many music- and sound-related things have been documented. I do have the starting point for such things, though, via my old blfind program.

you can see some differences in the pixels

Well, you can open up a sound file in Audacity, convert it to 8-bit unsigned PCM, and place the sound file over where the audio you want to replace is in the ROM (opened up as a RAW file in Audacity)

In that case, writing a python script to do that automatically shouldn't be too difficult. Could possibly even handle repointing; there should be a pointer table somewhere. I never did finish debugging that sound bl...

Alright, following some work, I was able to find a big table of all sounds in the game at 08F2C0 and determined that the data best fits as 8-bit signed PCM (like gbatek says the DMA channels use) at 16384 Hz in one channel. I still don't understand how to determine the lengths of samples, though.

If I were to make a (relatively good) program for editing the game's sound samples, I'd have it read the pointer to the table from 003FEC (or a user-specified location), make it able to relocate said table, give it the ability to relocate the samples themselves, and obviously have it convert input files to the necessary format. I'd still need some help determining sample lengths, though - the subroutine starts at 08003FAC hinthint. Huzzah!

    Since when did people use scientific fact to justify hacking laziness?

    This document seems consistent with what I vaguely remember from my previous attempts at hacking MZM sounds. Probably useful indeed.

    Oh wow, I never even thought of looking up a doc about sound implementation.  Very recent actually, wondered how I missed that doc
