Rogue Squadron uses MusyX. What compression does it use? Is it documented?

All right, I see.

So delroth has said something about a 4-bit ADPCM, coefficients, the initial yn1/yn2, the loop points and loop yn1/yn2, and something about no exceptions. I have no idea what this means, and I don’t know if you know any better than I do. Can you tell me what you do know about it?
