It's good that you're fixing the heal pad! :D I just started playing Borwn again and when I was in the Haunted Forest, it annoyed me that I couldn't heal. >_< Additionally, is Shadow Ball meant to be a Dark type move? Because, if I remember correctly, in the games it's ghost. Sorry if this is intentional.
Finally, I am really glad Brown is getting updated! :D I think it is a really great ROM hack and I always find myself playing it over and over again! xD Completed it 2 or 3 times now, I lost count. xD
