Yes, there are prototypes of this game that are accessble to us as the general public due to the nature of leaks e.t.c. These can be found with a good bit of research on the internet, although they're very hard to find (if you struggle try to contact others). You either need a soft-modded Wii/Wii U with a USB Flash Drive compatible with the programs you're using or Dolphin emulator for the GameCube titles. We can't be held responsible for anything you do to your Wii, so choose your methods wisely.
