Harp Weapon Tutorial

I do want to thank everybody for their suggestions.  Granted I wouldn't even know where to look and what to change with hex coding.  I didn't have much luck with the weapon part.  I was able to use a tool as a weapon graphic, but the character would not take a step forward and would result to him stepping backwards.  While I wanted to try using the attack animation for the Crasshoppr, I don't know how to find that in the hex editor nor where to apply it to a weapon. I can use the editor provided I know where things are. I tried using the Rommaps you provided, but I can't understand a lick of it.

I did manage, looking through the forums, how to use Bannon's Health command and used it to play the imp song.  I used the hex editor to change the ability from Cure 2 to Imp song and used FF3usme to use bannon's subroutine to show the imp song animation.  However I can only get the ability to work on the party.  I want it to only target the enemy, but I can't figure out how to do it. Can anybody help me figure out how to set the Bannon Health command to affect the enemy party?
