Often abbreviated to N64 and stylised as NINTENDO⁶⁴, 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. The console leaped from 16 bit sprite-based graphics into a polygon world thanks to its powerful 64-bit CPU and GPU, thus giving the console its name.  The Nintendo 64 was Nintendo's last home console to use cartridges, though Nintendo's handhelds would continue to support the format.
