An Early Zelda 64 Prototype Had Portals Throughout Hyrule Castle The early tech demo has never been seen by the public. Former Nintendo developer Giles Goddard is probably best known for his work on Star Fox, or for Super Mario 64's stretchy Mario face, but it turns out he had a hand in the earliest days of Zelda on the Nintendo 64 too. In a new interview with MinnMax, Goddard reveals that he worked on an early Zelda tech demo that had Link navigate Hyrule Castle through a series of portals. Goddard starts out talking about the Shoshinkai 1995 demo, a brief clip of Link fighting a metallic enemy, which he created to show off the potential for a 3D Zelda and the capabilities of the then-unreleased Nintendo 64 console.
