A very newbie-ish question here. (Also, why am I homebrewing the DS in 2016?) The DS has two processors, ARM7 and ARM9. But my current project which uses NitroEngine doesn't have the /ARM7 and /ARM9 folders like other projects - Instead it only has /data, /source(with main.c inside) and a single MakeFile. Building and running the output .nds works. Even sound output(which is only supported my ARM7) with Maxmod! Is this normal? Are those /ARM7 and /ARM9 folders necessary? And what do I have to do to have both screens active ALONG WITH sound/music?
