Quick Getting Started Guide

Due to the numerous different distributions and hardware platforms Linux runs on, desmume for Linux is only offered in source code form. This means you have to build a binary (compile) Linux for yourself. If you do not know how to do this, please refer to Installing DeSmuME from source on Linux.

Once you have build and installed the binary, you will have 3 different Linux ports to choose from: desmume gtk+, desmume gladde, and a desmume command line port. This manual is about the GTK+ port. You can start it by typing 'desmume' on the command line.

When you start the emulator for the first time, you probably just want to play a certain game. You can do this by going to 'File' in the menu, and selecting 'Open'. This will open up an explorer window, within which you can browse to the rom (nds file) that you wish to play. Once the game has finished loading (and this should only take a few seconds at most), you need to start the game. You can do so by choosing 'Emulation|Run' from themenu, or by clicking on the 'Run' button.

Command Line Options

This port of desume has several command line options, which will be listed here :


Loads savegame from slot NUM


Enables using OpenGL for screen rendering


Use software colour conversion during OpenGL screen rendering. May produce better or worse frame rates depending on hardware.


Select available 3d emulation: 0 = 3d disabled 1 = internal desmume software rasterizer (default) 2 = osmesa or gtkglext opengl (if available, depending on compilation options, see desmume --help)


Disables the sound emulation


Disables the 60 fps limiter


Enable the ARM9 GDB stub on the given port
