The Nintendo DS is a handheld game console developed and manufactured by Nintendo. It was released in 2004 in North America and Japan. The system's code name was Nitro, which can be seen in the model number that appears on the unit (NTR-001).
On March 2, 2006, Nintendo released the Nintendo DS Lite, a redesign of the Nintendo DS, in Japan. It was later released in North America, Europe, and Australia in June 2006. The DS Lite is a slimmer and lighter version of the Nintendo DS and has brighter screens. Nintendo of America refers to the older model as the "original style" Nintendo DS.
