I have noticed most people play on any language. But what version do you use? I have seen Normal Disc, Nintendo Select, or download off the virtual console. Which is best?

As far as we can tell it doesn't matter whether you use a disco or digital copy, their load times are all the same (or if they are different, the difference is so small it's not noticable). As for language, you'll want to play on either Spanish or Italian.

Does the North American release version have those language options?

The North American Wii u can be changed to Spanish and the European Wii u can be changed to Italian. The game doesn't have language selection, but the Wii u does.

Got it. And as far as versions, select, original and download there is no difference? No patched glitches or anything?
