This music will be playing while you fight some of the new bosses in this game. They are fully custom coded.

Download for the tool:

Expect an actual preview of the mod within the next few days.

Put 2 files called "intro.m64" and "loop.m64" into the folder of this tool. Both have to have "looping enabled" when creating. The tool will then fuse them together, so that the intro will play only once, while the loop repeats. You can still only use one Instrument set though.
