Hey i used to be called bigglich72 but now it’s metroid98.
Anyway, I know how you can use MP3 music in the game with out slowing down the loading part.
You just set an action to replace the midis that are present with the mp3.
If it makes the download to big, then i have it covered.
Just make the MP3 music pack as a separate download, and if a player decides not to use them, the midis will play instead.
