Since the game is already supposed to read files that are missing from the CD, All I did was simply to insert the missing files into the ISO.

I don't see any reason why runs with the missing music (or any other music) won't be accepted, but I'm asking just in case.

(Ignore the fact that I put the wrong music in the credits)

I'm fairly sure Cyberdemon would allow it. She allowed the command line option "-mpeg" to disable cutscenes which is more severe than what this is here.

yep, should be fine. I was thinking of doing this myself actually

Just for future reference, I uploaded a small .zip file to github that contains all the missing soundtrack, as well as some dlls that allow you to run the game in windowed mode. You can find it here: https://github.com/MrMonsh/BLoSC/releases/tag/v1.0.0

To install the files simply extract the contents from the zip file directly as-is into the root folder of the game (which would be where buzz.exe is contained).

PS: If you're not really interested in running in windowed mode, you can just dispose of any files outside the ...\data\audio folder of the zip file.
