The short response is to change the battle music of the two executives (male and female) and scientist (whom are exclusively fought in allegiance with the grunts in Crystal)

The long one is to find an approach to doing this. I read somewhere that there isn't any room in the offset space asm where the Rocket Battle music could work for rocket male grunts and female grunts.

In reference to this topic
http://hax.iimarck.us/topic/855/

the solution for this is to:
Find a large blank space in the rom
Put asm code on that space for the three trainer types

So the first question is
Can I find an empty space using jiggly puff asm? For example, a good, safe offset that doesn't corrupt or overwrite anything and it is easy to access?

Second question is, what code would I need to write (or copy within the two rocket grunts battle music, using jiggly puff asm?

This is for the goal of giving the executives type and scientist type team rocket battle music, alongside the two grunt types, for pokemon Crystal.
