It is quite humorous at this point to notice this fact. Indeed, the digital version of the Zelda history book, Hyrule Historia, still has the medallion mix up in it. Definitely not a huge deal in the grand scheme of things, but it is kind of hilarious when you remember that this mistake went unnoticed in the initial Japanese version as well as the later released North American version. I suppose that Nabooru and Darunia will have to be content with their switched up medallions.
