We actually enjoy playing our DS in the car quite a bit. In fact, one of us even went so far as to enjoy playing Puzzle Quest at red lights while behind the wheel. It's a dangerous obsession that not only threatens our own lives, but those of everyone else in the world. It's the nature of the beast, we suppose.
So imagine our surprise when we read this little piece and totally realized we could output our DS's sound to our car speakers, almost providing a surround sound experience. Sure, we have headphones for when we're trying to get our dual-screen on out in the wild, but sometimes they're uncomfortable. This just seems like an incredibly obvious thing we never thought of ourselves. We can totally picture playing Ouendan or Elite Beat Agents in this manner.
