Although the Rumble Pak works with both the Nintendo DS and the redesigned Nintendo DS Lite, it protrudes from the Nintendo DS Lite when inserted, as do Game Boy Advance cartridges, because of the Nintendo DS Lite's smaller size. For this reason, a smaller version of the Rumble Pak is available in Japan, which is flush with the system when inserted. It was initially available in just black, but other colors produced by unlicensed accessory manufacturer eWin, such as white (see picture), have been released. Other color variations have been released by eWin.
