Is it possible to make a homebrew app which takes advantage of the ds rumble pak and use it to play mp3 music on the ds with the rumble pak acting like a bass? Not have it make weird noises, have it rumble/vibrate like a normal bass would do. If it is possible, can someone PLEASE make it? Can there be a setting to have the rumble adjusted (like from rumbling a lot to barely rumbling, for in case the song has too much bass and you don't wanna burn out your rumble pak) Thanks! BTW Would it be compatible with an r4, or does it need a more powerful flashcart?
