Sorry I know it's signed but forgot to mention it. Yes, it's the character voices. I guess ADPCM is close enough to linear PCM that it can be read as linear PCM and sound pretty accurate? It did sound slightly different when I imported the data into Audacity from the rom but it was so close that I chalked it up to different hardware handling it slightly differently.

Thanks for the suggestion - I'll see what I can do with ADPCM. First time trying to import the original sound data as ADPCM, it seems a little more distorted than it did with linear PCM but it's at least something to start playing with.

Thanks all for the input!

P.S. I haven't yet figured out how to find the exact start of a sound clip with whatever header info might be present (i.e. exactly how the sound chip reads and processes it) so I'm just working with the data raw. *Hopefully* that's not part of my problem but if I don't get very far going the way I'm going now, I'll switch my attention back to trying to understand what the sound chip is doing. My current approach *seemed* like the easiest way to get some success but maybe that was a flawed approach from the start.
