Copying to your ROM a song available on the Forum

Maybe try not moving the song pointers? If you are moving instrument data then there is no need to move song pointers, as they can just expand into the space that instrument data was previously using. I had a lot of trouble with getting relocated song pointers to work, and eventually realized that it was a totally unnecessary step and stopped trying and all my problems went away. I don't actually remember *what* the problems I was having were, though ...

Also, make sure it works without the new background music asm hack first before testing with it. Change $C2BF3B from 24 to 56 and get into a battle, for example.

And make sure the battle you're using for testing actually has music normally!
