1 Compiling instructions______________________________________

DeSmuME is written in C using the gtk+ and SDL libraries.
So you need a working C compiler, such as gcc and
the above libraries runtime and development packages:

  * http://www.gtk.org

  * http://www.libsdl.org/

Once these libraries are installed, you should be ready to
install DeSmuME.

DeSmuME provides another interface based on libglade, to use
it, you'll need glade:

  * http://glade.gnome.org/

1.1 From a release archive____________________________________

Uncompress the DeSmuME archive, move to the newly created 
directory, type "./configure", then "make".
It will generate three programs:
1) "desmume" in the "src/gtk" directory;
2) "desmume-cli" in the "src/cli" directory.
If glade is installed on your system, you'll get a third
binary:
3) "desmume-glade" in the "src/gtk-glade" directory.

You can even type "make install" to install those programs on
your system (in /usr/local/ by default), then uninstalling is
done by typing "make uninstall".

1.2 From a CVS copy___________________________________________

Move to the toplevel directory (the one that contains the
configure.ac file). Type "./autogen.sh" to generate the
configure/install scripts and needed Makefiles. Then you can follow the
same procedure as in 1.1 .

2 How to use DeSmuME__________________________________________

There are three versions of DeSmuME under Linux. These are a
Gtk+ build, a Glade build and a CLI SDL build. All these builds
have some common command line options:

--disable-limiter   Disables the 60 fps limiter
--soft-convert      Use software colour conversion during OpenGL
                    screen rendering. May produce better or worse
                    frame rates depending on hardware.

--arm9gdb=PORT_NUM  Enable the ARM9 GDB stub on the given port
--arm7gdb=PORT_NUM  Enable the ARM7 GDB stub on the given port

--cflash=PATH_TO_DISK_IMAGE
                    Enable disk image GBAMP compact flash emulation

--help              Display this message


NOTE:
The Gtk+ and Glade builds use gtkGLext to handle the OpenGL
rendering and contexts. You may get improved performance by
also passing the argument --gdk-gl-force-indirect. This has
been seen to improve things for Nvidia based graphics cards
under Linux.


GDB Debugger Stubs:
Source level debugging of ARM9 and/or ARM7 code is supported
using a GDB/Insight debugger.
The GDB stubs are enabled from the command line using the
following options:

--arm9gdb=<PORT_NUM> (for the ARM9)
--arm7gdb=<PORT_NUM> (for the ARM7)

The PORT_NUM is the TCP port upon which the stub will listen for
connections. Once enabled you can connect to the stub using the
following command at the GDB debugger prompt (assuming GDB and
DeSmuME are running on the same machine):

target remote :<PORT_NUM>

NOTE: there are problems with the ARM support when stepping code
with GDB versions prior to version 6.6. It is recommended that
you use at least version 6.6 if possible.


GBAMP compact flash emulation:

The default behaviour of DeSmumME is to attempt to emulate the
FAT image for the contents of the directory where the running
.nds file was located.
This behaviour can be altered using the
--cflash=<DISK_IMAGE_FILE> command line option. Using this
option DeSmuME will emulation a GBAMP and read and write sectors
from/to the disk image file.
The disk image file must be created and populated with files
using some external tool.
NOTE: currently if desmume fails to open the disk image file it
will silently continue minus a working GBAMP emulation.


2.1 Gtk+ version______________________________________________

Type "desmume" in a shell, a window should appear, then open
a rom file using the "open" button, next use the "run" button
to start emulation.

The following command line options are specific to the Gtk+
build:

--opengl-2d         Enables using OpenGL for screen rendering
--disable-sound     Disables the sound emulation
--disable-3d        Disables the 3D emulation


2.2 CLI SDL version_______________________________________________

Just type "desmume-cli path-to-a-rom" in a shell.

The following command line options are specific to the CLI
build:

--opengl-2d         Enables using OpenGL for screen rendering
--disable-sound     Disables the sound emulation
