Mupen64Plus is a plugin-based N64 emulator for Linux which is capable of accurately playing many games. Included are four MIPS R4300 CPU emulators, with dynamic recompilers for 32-bit x86 and 64-bit amd64 systems, and necessary plugins for audio, graphical rendering (RDP), signal co-processor (RSP), and input. By default the gtk2 GUI will be built. To build the Qt4 GUI pass GTK2=no to the script. libsamplerate is an optional (but recommended) dependency. It is also available from SlackBuilds.org
