From this article:
While there are no photos of the PlayStation 4 version floating around at the time of writing, the folks at Nintendo Everything were able to get a screenshot of the 3DS version. Shockingly, the free version doesn't appear to be any of the Famicom, Game Boy, or Super Famicom versions, but an entirely new one. Personally, I'm blown away by this, as not only is this basically free, but that means Square Enix updated the game for two different types of hardware.
