The SDL port to the Nintendo DS

This port uses the devKitPro toolchain, available from:
http://www.devkitpro.org

Precompiled tools for cross-compiling on Linux are available from:
http://www.libsdl.org/extras/nds/devkitPro-20070503-linux.tar.gz

todo:
add ds console specific features/optimizations
mouse/keyboard support
dual screen support

build with:
cp include/SDL_config_nds.h include/SDL_config.h
make -f Makefile.ds

included is an arm9/arm7 template to allow for sound streaming support.

Enjoy, fix the source and share :)
