150cc in Mario Kart DS not enough of a challenge for you? How about playing it at nearly double the speed? XCM has created a "Hyper Gear" case that overclocks your poor little DS to either 1.4x or 1.7x its regular speed. You can see the little switch in the bottom right of the case in the picture above. Of course, overclocking a DS isn't like overclocking a PC - everything speeds up. Sound, graphics, gameplay, everything. Check out the video over the jump for some idea of what it'll be like (though the DS in the video isn't being overclocked by the case). The XCM Hyper Gear will be available in the next few weeks from your favourite DS modding websites...
