WarioWorld was Nintendo's website for registered third-party developers from approximately 1997 to 2014; it was replaced by the Nintendo Developer Portal.
Due to a lack of leaks by WarioWorld users of the internal pages of the website, very little about it is known other than the few introduction pages which were exposed publicly, detailing information such as the registration requirements.
Over the years, it supported developers of a number of platforms including:
- Nintendo 64
- Game Boy Colour
- Nintendo GameCube
- Game Boy Advance
- Nintendo DS
- Nintendo Wii
- Nintendo Wii U
- Nintendo 3DS
