Hopefully, this is in the right place... I'm still getting used to the new setup. (And this is for the 3DS, of course.)
Whether or not it's another version of Kyle or a relative, a "BBY Kyle" Special Mii is now available through SpotPass, in honor of a special Best Buy-only StreetPass weekend event.
BBY Kyle wears the NES hat, has Ultimate NES Remix as his last-played game. He should have all puzzle pieces available to choose from, so those of you willing to use the exploit can have another opportunity to try it.
