Videogame Design Documents? Graph paper sprites, etc

Anyone have a good place to find lots of this stuff? I would absolutely buy books of this kind of thing if they existed, especially for Zelda/Mario/FF.

There‘s something I haven’t been able to find for years: images of a prototype of what would become animal crossing.

A zelda-like 64DD game that runs on internal clock, where the hero makes use of animals to clear puzzles.
