I know, we need SOME help otherwise it would be too much; btw I've changed it so the Kanto leader music plays when battling Bugsy, I think we should try an import some kind of Johto Leader sprite so it looks better?
Remove the entrance on Vicotry road, make a warp on Island four leading to the start of the cave. :)
The music, go in Sappy and look for Battle 1 and 2. Play them. It should be them. use those numbers and put it into the music box in A-Trainer.
