this reminds me of the days when i was a teenager in the 80s and one of my hobbies was ripping the music from video games which basically meant identifying and isolating the code and data responsible for the audio. i remember taking a hex monitor and browsing/ scrolling through all the 64k memory of the commodore c64 and i could tell you just by looking at visual repeating data patterns in the raw hex dump where the song data was located.
