Eh, looks good enough to me on Dolphin Emulator with hd texture packs.
In all seriousness though there isnt a good reason for Nintendo to do so. It isnt a game that will sell millions like a Zelda remake can and its not a game with a direct sequel releasing on a new console that many may not have had the chance to play such as Bayonetta 1 and 2 or Gravity Daze 1 and 2.
