Zelda's Birthday is probably a fan-made ROM hack or a completely original game for the Nintendo 64 based on the Zelda franchise. Without more information, it's impossible to be certain of the gameplay or its origin. The title itself suggests a playful approach, potentially with thematic content centered around a birthday celebration within the context of the Zelda universe.  It is not an official Nintendo release.
