Sweet!
To celebrate, let's all go get some cake!

So, I'm confused; is it an OFFICIAL game, like Mario/Zelda/etc? Or is it just a "fanmade ROM hack"-type of thing that happens to be on a real cartridge? Because I mean, if it's "official", then wouldn't Nintendo have to license/publish/approve/something it? That dosen't seem likely...

Forgive my noobish ignorance, but I don't know how some of the video game industry stuff works.
