To build this application using make, you will need wut and the following devkitPro packages: ppc-zlib ppc-libmad ppc-libogg ppc-libgd ppc-freetype ppc-libjpeg-turbo ppc-libpng ppc-libvorbisidec ...
Acquire devKitPro and libnds+dswifi, then run make. Sound will probably be broken on most flashcarts, so you need to compile this rom with libnds commit 62c8ffd, or launch it with a compatible hbmenu.
