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.
|
