Then I'll send you the tracks for it.

1. Open up Sappy and Load your rom.
2. Go to
Battle 3(Which is the Gym Leader Music)
3. Before you do anything else, put the tracks that I gave you into
the folder with your rom.
4. Go back to Sappy and press import tracks. Click all the numbered files.(which will be 0, 1, and 2.
5. Now find an open space in your rom(music takes a lot of space).Then put that offset(0xOFFSET) into FIRST TRACK.
6.For Voice offset, put 48B8B8(Which is for the Suicune theme)
7. Then press ok.
BTW, I can be your music inserter. But I can't assemble music anymore since my assembler got messed up. So I can only import tracks. But I can
only use music from Firered and Emerald.
