DeSmuME Manual

DeSmuME places responsibility on the developers of each port to expose emulation features in a way that is tuned to the needs of that platform. As a consequence, some ports are able to move well ahead of the others. Conversely, some ports are far behind some others. As a consequence, some behaviours and menu structures are different in each port. Therefore, the decision was made to create separate manuals for each port as well: when a specific port is changed, only the manual for that specific port needs to be altered.


DeSmuME Manual for the Windows port

DeSmuME Manual for the Linux GTK+ port

DeSmuME Manual for the Linux Glade port

DeSmuME Manual for the Linux command line port

DeSmuME Manual for the Macintosh port

Common command line arguments

The GTK+ and windows ports share common command line arguments. We are trying slowly to move over to a common command line parsing engine. The commandline arguments for these platforms are described here:


Loads savegame from slot NUM


Specifies a dsm format movie to play


Specifies a path to a new dsm format movie


Indicates that emulation should start paused


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


Enable the ARM7 GDB stub on the given port


Select savetype from the following:

0 = Autodetect
1 = EEPROM 4kbit
2 = EEPROM 64kbit
3 = EEPROM 512kbit
4 = FRAM 256kbit
5 = FLASH 2mbit
6 = FLASH 4mbit


Set the language in the firmware, LANG as follows:

0 = Japanese
1 = English
2 = French
3 = German
4 = Italian
5 = Spanish


Enable disk image GBAMP compact flash emulation


Quit desmume after the specified seconds for testing purpose.
