haha that was one of my scripts for my oot map! And yes i did get it I haven't had a chance to look at it yet though!
this would be pretty easy to do actually, the only hard part would be calibrating the arrow to be accurate to your position.
Its cool your doing this, I've already done it though and I'm extremely far along, I welcome you to continue though it looks pretty good so far. I see a couple problems in kokiri forest though if your interested in being 100% accurate
i am also remakeing ocarina of time on adventurecraft i am starting to work on link house and i might use a texture pack for my map to
