Nintendo has no REAL anti-piracy mechanism except this: If you buy the game you get free accessories that only work on this game and that this game needs!
An example would be Wii Sports Beach Resort where Motion Plus is required to play the game. No motion plus no game, no game no senseless fun, no senseless fun no friends. Anyway this can easily stop piracy since the ISOs need to be downloaded to be played on a chipped or soft-modded Wii. Since you can’t physically download hardware you can’t get motion plus for free.
A real life example would be Wii Fit. As far as I am aware it is impossible to illegally acquire a working copy of Wii Fit that will fully function on your Wii.
