Nintendo Co. is demanding South Korean authorities crack down on copyright violations by companies circulating illegal copies of its games, a company spokesman said Tuesday.
Nintendo's South Korean unit filed a complaint Monday with the Seoul Central District Prosecutor's Office, demanding action against those who are illegally copying and selling Nintendo games on Web sites, said Ken Toyoda, Nintendo's spokesman.
Kyoto-based Nintendo's portable game machine, the Nintendo DS Lite, went on sale in South Korea in January, the first Nintendo machine sold there, Toyoda said.
Sales in South Korea reached 270,000 units in the first four months.
Nintendo, which also makes the Wii family console and Super Mario game software, said earlier demands to Seoul hadn't produced results and the company is considering further measures if the infringements continue.
