How do I change the music that plays in the "Leaving Yoshi Outside" cutscene? Is it tied to a level, or is it tied to a song number?"What's 9 + 10?"
-Jah
You would have to change the default castle music in the tweaks.asm file. Do note that it's this way for every castle entrance cutscene.
Same thing goes for ghost house cutscenes with their default ghost house music.
