No, the above clip isn't our primary subject for this week's The DS Life, but it is related and, not to mention, totally awesome.
Looking for a more console-authentic experience with Guitar Hero: On Tour, Hack A Day reader Eric Ruckerman modified a wireless Guitar Hero PS2 controller to fit a Nintendo DS and wired the peripheral's buttons into the system. He also added a transmitter to play the game's sound through his home sound system.
Pretty slick, but how can he see the notes coming down on the screen? A mirror would help! Anyway, step past the post break for a shot of Eric's setup and a photograph of someone playing Guitar Hero: On Tour with more traditional controls.
