I installed mupen64plus from the repositories using Synaptic. I like the emulator (for the most part, a couple of graphics glitches on TLOZ Ocarina of Time), especially its performance on my old machine, but I cannot figure out how to configure the controls for myself. I tried looking at Google Code's guide here but I can't find the file I need to edit and the link with the key ids isn't working, so even if I could find the file I wouldn't be able to change anything. So what I need is a resource with the key ids and where to find the file I need to edit.

I am running Ubuntu 12.10 32-bit. 2GB RAM, Intel CORE 2 DUO @ 2.00GHz

Here's an additional part of the question. M64py is a popular option. However, it requires that you input the paths to the various files it needs. Where are the default locations? Include for both the 32 bit system and a 64 bit system. (The files needed are Library file, Plugin directory and Data directory.)

You can configure the controls using a configuration file. The preferred method would be to use a frontend which has controller settings.


M64py is a Qt frontend for Mupen64Plus. It can be downloaded from here

It has a controller configuration ui as pictured here

You can configure the controlls from here and then launch the games from here itself or actually run mupen64plus /path/to/rom in the terminal

I myself couldn't run a GUI for mupen, so I ended up figuring out how to configuire it and run it in the Terminal. The file I used to configure the controllers is:


There I found the area where it talked about the joysticks and figured by trial and error that if I see on my controller a number (the buttons are numbered) I type that number minus one in the config file, and for the buttons I was not using I just leave it blank, as in "". I'll leave the code I used:

    # Mupen64Plus SDL Input Plugin config parameter version number.  Please don't change
    version = 1
    # Specifies whether this controller is 'plugged in' to the simulated N64
    plugged = True
    # Specifies which type of expansion pak is in the controller: 1=None, 2=Mem pak, 5=Rumble pak
    plugin = 2
    # If True, then mouse buttons may be used with this controller
    mouse = False
    # Specifies which joystick is bound to this controller: -2=Keyboard/mouse, -1=Auto config, 0 or more= SDL Joystick number
    device = 1
    # SDL joystick name (name check disabled if this is empty string)
    name = "DragonRise Inc.   Generic   USB  Joystick  "
    # Scaling factor for mouse movements.  For X, Y axes.
    MouseSensitivity = "2.00,2.00"
    # The minimum absolute value of the SDL analog joystick axis to move the N64 controller axis value from 0.  For X, Y axes.
    AnalogDeadzone = "4096,4096"
    # An absolute value of the SDL joystick axis >= AnalogPeak will saturate the N64 controller axis value (at 80).  For X, Y axes. For each axis, this must be greater than the corresponding AnalogDeadzone value
    AnalogPeak = "32768,32768"
    # Digital button configuration mappings
    DPad R = ""
    DPad L = ""
    DPad D = ""
    DPad U = ""
    Start = "button(9)"
    Z Trig = "button(6)"
    B Button = "button(1)"
    A Button = "button(0)"
    C Button R = "axis(3+)"
    C Button L = "axis(3+)"
    C Button D = "axis(4+)"
    C Button U = "axis(4+)"
    R Trig = "button(7)"
    L Trig = ""
    Mempak switch = ""
    Rumblepak switch = ""
    # Analog axis configuration mappings
    X Axis = "axis(0-,0+)"
    Y Axis = "axis(1-,1+)"
