Mega Man X Music

[Sprite:D]

Is it possible to change which music track plays in a stage in X1? I want to swap Launch Octopus with Flame Mammoth and vice versa, but I haven't been able to find any info on how to do something like this.

I've had this for a while but haven't used it as much.

These are the offsets to the music that plays in each stage. You can change it to any values you want.
I have both header and unheader offsets:

Is this from a hacking document somewhere, or are you working on a disassembly?

I found it on a website years ago, 13 years to be exact.

And I found the hex values myself through experimentation.
