More documentation can be found on the Mupen64Plus website and you can find a more complete README file on the wiki.

Mupen64Plus is based off of mupen64, originally created by Hacktarux. This package contains only the Mupen64Plus core library. For a fully functional emulator, the user must also install graphics, sound, input, and RSP plugins, as well as a user interface program (called a front-end).

1. Requirements and Pre-requisites

Binary Package Requirements

Source Build Requirements

In addition to the binary libraries, the following packages are required if you build Mupen64Plus from source:

2. Building From Source

If you downloaded the binary distribution of Mupen64Plus, skip to the Installation process (Section 3). To build the source distribution, unzip and cd into the projects/unix directory, then build using make:

 $ unzip mupen64plus-core-x-y-z-src.zip
 $ cd mupen64plus-core-x-y-z-src/projects/unix
 $ make all

Type make by itself to view all available build options:

 $ make
 Mupen64Plus-core makefile.

     PROFILE=1      == build gprof instrumentation into binaries for profiling
     DEBUG=1        == add debugging symbols to binaries
     DEBUGGER=1     == build debugger API into core for front-ends.  runs slower.

3. Installation

Binary Distribution

To install the binary distribution of Mupen64Plus, su to root and run the provided install.sh script:

 $ su
 # ./install.sh
 # exit
 $

The install script will copy the executable to /usr/local/bin and a directory called /usr/local/share/mupen64plus will be created to hold plugins and other files used by mupen64plus.

NOTE: By default, install.sh uses /usr/local for the install prefix. Although the user can specify an alternate prefix to install.sh at the commandline, the mupen64plus binary was compiled to look for the install directory in /usr/local, so specifying an alternate prefix to install.sh will cause problems (the mupen64plus front-end application will not find the directory containing the core library) unless the directory to which you install it is known by your dynamic library loader (ie, included in /etc/ld.conf.so)

If you want to use a prefix other than /usr/local, you may also download the source code package and build with the PREFIX option (see below).

Source Distribution

After building mupen64plus and all plugins, su to root and type make install to install Mupen64Plus. The install process will copy the executable to $PREFIX/bin and a directory called $PREFIX/share/mupen64plus will be created to hold plugins and other files used by mupen64plus. By default, PREFIX is set to /usr/local. This can be changed by passing the PREFIX option to make.

NOTE: You must pass the prefix, when building AND installing. For example, to install mupen64plus to /usr, do this:

$ make PREFIX=/usr all
$ sudo make PREFIX=/usr install
$

Custom Installation Paths

You may customize the instalation of Mupen64Plus by using the options for the install.sh script:

Usage: install.sh [PREFIX] [SHAREDIR] [BINDIR] [LIBDIR] [MANDIR]

PREFIX - installation directories prefix (default: /usr/local) SHAREDIR - path to Mupen64Plus shared data files (default: PREFIX/share/mupen64plus) BINDIR - path to Mupen64Plus binary program files (default: $PREFIX/bin) LIBDIR - path to Mupen64Plus plugin files (default: $SHAREDIR/plugins) MANDIR - path to manual files (default: $PREFIX/man/man1)

You must pass the same options to the uninstall.sh script when uninstalling in order to remove all of the Mupen64Plus files.

You should install the Mupen64Plus plugins (libraries) in their own folder. If you install them in a common directory such as /usr/lib and then later uninstall them with sudo uninstall.sh LIBDIR=/usr/lib, it will delete all system libraries.

If you install with SHAREDIR in a place other than /usr/local/share/mupen64plus or /usr/share/mupen64plus, and BINDIR is not the same as SHAREDIR, then users will have to run Mupen64Plus with the --installdir= option, otherwise they will get an error. The mupen64plus executable looks in up to 5 different directories in order to find the Shared Data Directory. The order in which the directories are searched is:

If you choose to install the plugins in a non-standard location (someplace other than $SHAREDIR/plugins), then you must set the PluginDirectory parameter in the mupen64plus.conf config file to the directory path in which the plugins have been installed.

4. Key Commands In Emulator

The keys or joystick/mouse inputs which will be mapped to the N64 controller for playing the games are determined by the input plugin. The emulator core also supports several key commands during emulation, which may be configured by editing the ~/.config/mupen64plus/mupen64plus.cfg file. They are:
