attached to this post you will find all the Bound High Background music and all the sound effects recorded from hardware. I managed to do this by recompiling the games source code after activating previously deactivated debug features. I will publish the results soon in a different post. As far as I can tell track 16 and 19 are not used from the code. Track 16 seems to be an alternative for track 5. Track 8 (the death music) has a nice easter egg hidden at the end.
Special Thanks goes to all my Patreons (especially to Randy Jeffery). I used the money to buy a set of audio and video conversion tools which made this quite a bit easier. I plan to use them on my youtube videos as well.
