Here we have a video of a guy passing his DS through an external circuit board and adjusting the system's internal clock speed. Assuming that this isn't an elaborate fake, it's interesting to see how Mario Kart DS behaves at different clock speeds. At the overclocked rate, it practically transforms into F-Zero. Anyone that's tried to run old DOS games on a newer PC may have encountered similar speedy results. All this begs the question:
Where the heck is F-Zero DS?
