The arrow was a hardcoded change made by sony (the dot never changed direction) so theres really nothing we can "look at"
the problem with a round compass.. right now all we can do is point the game to a strip for the compass and the game is hardcoded to move the strip left and right as you turn. I dont think we'll ever be able to make it go in a circle. Once upon a time tho, sony had one..
