Hi! I am currently working on a hack of NSMB, and am wondering how to change the music for only one level without actually changing the music in the game's file system. I tried to use the "Sound Set (HEX)" box, but I cannot work around it.

Thanks.

Instead of setting the music per level, you set it per view. After you have a view created, you can change the music in there.
