MUPEN64 is a n64 emulator designed to be multi-OS. It is developped on/for Linux but a Windows version is available. Actually, the program can be easily ported on all OS supported by the SDL library. What this emulator is able to do ? Nothing really impressive... but it has many things already implemented such as a dynamic recompilator. It is compatible with all 100% CPU demos that I have found and it shows the mario64 title and only on the interpretive mode of the Linux version the mario's head (No texture yet). You can find earlier versions of Mupen64, ported to other playforms, such as Mac, QNX, and BeOS, at the Mupen64 website.
