Project64 is a Nintendo 64 emulator for Windows by Zilmar, Jabo, Tooie and Witten.
Project64 or PJ64 dates back to its first public release Project64 v1.0 in May 26th 2001. Project64 is an emulator designed to emulate a Nintendo64 video game system on a Microsoft Windows based PC. It creates an environment on your PC which real N64 software can run and be played in much the same way as it would be on the original hardware system.
It has a fantastic compatibility and is one of "if not the best" N64 emulators out there. The gameplay is a pure pleasure and is entertaining for all N64 based fans, but your computer had better meet or excel the Minimum System Specifications.
