The success of the Wii has helped Nintendo to double its profit in the six months to the end of September.
Demand for the console has outstripped that for Sony's Playstation 3 and Microsoft's XBox 360 - selling about 7.3 million units.
The Japanese firm made a net profit of 132.4bn yen ($1.16bn; £506m) from 54.4bn yen a year earlier.
Popularity of the handheld DS also helped, with Nintendo selling about 13.4 million of the consoles.
The DS console, which allows users to control play with a stylus, has proved popular with women and older users.
Meanwhile the motion sensitive Wii has proved popular after introducing a new way of playing computer games. (see earlier post)
