The Nintendo 64 was Nintendo's third major home video game console. Project Reality was the code-name of the console being worked on by Nintendo and Silicon Graphics (SGI) in April 1993 to create a next-generation 3D console. The console leaped from 32 bit, sprite based graphics into a polygon world thanks to its 64-bit GPU, thus giving the console its name. The Nintendo 64 was the last home console to use cartridges, though the Game Boy Color and Game Boy Advance after it would continue to support the format.
