Build

customized linker scripts, simulator support is currently limited to x86 and
x86_64 archs. Following dependencies have to be met:

Configure

Open a terminal and type:
Open a (Cygwin) terminal, change to your checkout directory and type:
> make menuconfig
This brings up a curses based text interface for configuring certain aspects of
your target platform. Be careful if you use a full-fledged IDE like Eclipse to
manage the build, as integrated terminal emulators tend to choke on curses
generated shell output. Just ensure that 'make menuconfig' has been run at least
once in an ordinary terminal emulator after a fresh checkout or after issuing
'make mrproper'.

the simulator:

Simulator Handling
------------------
Please keep in mind that the simulator is NOT an emulator. All it does is
compile the source to a native host application so you can step through your
C-Code. The GUI thread reads the simulated frame buffer every 40ms and draws its
contents.
Joystick directions are simulated by the WASD keys and SPACE acts as the fire
button. The OpenGL based simulator (Linux/FreeBSD) enables you to adjust the
viewing angle of the LED matrix via the arrow keys (not available on Windows).
