Officials from Nintendo have announced details of the company’s first quarter financial results, for the period ended June 30th. During this time net profit for the company rose by 33.7 percent to ¥107.3 billion ($992m).

At the same time, net sales increased by 24 percent to ¥423.3 billion ($3.92bn). However, despite these positive results the company has left its full year predictions unchanged, apparently in light of falling demand for the Nintendo DS in Japan.

Total worldwide hardware sales for the Nintendo DS stood at 6.94 million for the three months, making for a lifetime-to-date total of 77.54 million. This represents a 0.04 million unit decrease from the same period last year, with the PSP having been consistently outselling the Nintendo DS all year in Japan.

Software sales however, saw an increase of 2.33 million units on the previous year to 36.59 million. The Western release of Pokemon Mystery Dungeon: Explorers of Darkness/Time was singled out by Nintendo as the most significant new release of the period.

The Wii sold a total of 5.17 million hardware units worldwide for a new lifetime-to-date total of 29.62 million. This represents an increase of 1.74 million units on the same period last year. Software sales saw an increase of 24.42 million units to 40.41 million.

The most significant software releases on the Wii were named as Mario Kart Wii, which has so far sold 6.42 million units worldwide and Wii Fit, which has sold 3.42 million units. Continued sales of Wii Sports (which is not bundled with the console in Japan) and Wii Play were described as “robust”.
