Looks good so far Bart. Normally I try and avoid "themed" mods and simply go with what is most pleasing to the eye in general, but I would happily throw obscure objects from other games when it comes to something as great as Navi being your targeting system arrow.
You could... Actually that would be better since it targets specific scripts of text presented to activate the sound. That way you don't get "Watch out!" when you check a TW mob lol.
