Nintendo has recorded a loss of ¥25.2 billion ($288 million) for the three months ended June 2010, compared to a profit of ¥42.4 billion for the same period last year.
The company blamed lower prices of DS hardware and an appreciation of the yen - overseas sales accounted for 86.5 per cent of business during the period.
Net sales for the three months were ¥188.6 billion ($2.1 billion), down from ¥253.5 billion, with operating income of ¥23.3 billion ($266.7 million), down from ¥40.40 billion.
During the period Super Mario Galaxy 2 sold 4.09 million units worldwide said Nintendo, with Wii hardware sales of 3.04 million units. Software sales for the home console were 28.17 million units.
Nintendo sold 3.15 million DS units for the three month period and 22.42 million DS games. Although the company highlighted strong sales of Pokemon Heart Gold and Soul Silver, and Tomodachi Collection, fewer newer releases impacted hardware sales.
Despite the losses, Nintendo continues to forecast a financial year profit of ¥200 billion and operating profit of ¥320 billion.
