I fiddled with the 3DS version of Ocarina of Time for a bit. Besides the updated graphics elucidating some unclear physical aspects, I was curious how they'd handle the ocarina. In the original N64 version, the five notes corresponded with the four C buttons and A. For the GC, the C button remained as a little nub and they continued to use the A, although you could also employ X, Y, and Z for some notes. The 3DS though... I wasn't certain. If you wanted to mimick the original N64 controller, I would make Y, X, and A correspond with left, up, and right accordingly, and then make L and R replace down and A. This is what I got instead:

It is really, really fucking confusing. I don't know what they discussed in the planning room, but I wouldn't've picked this. It's not very intuitive.
