The Magic Carpet 1001 hack made by Inventor called "Harry Potter", as well as it's other variant "Harry Tour", was known for it's ear-grating music throughout the game.
Inventor also made another hack called "Little Hag", based on the Harry Potter hack, which replaces Harry with a witch and significantly improves the music.
I just opened the NSFs for both the Harry Potter one and the Little Hag one in a hex editor. I opened the rom for the Harry Potter hack, replaced the hex data for the music with that of Little Hag and to my surprise, IT WORKED!
I've attached the zip file containing the modified rom of Harry Potter (as well one for Harry Tour).
