Nintendo has made a push to specific countries around the world to encourage more action against piracy. Nintendo submitted its comments to the U.S. Trade Representative under a "Special 301" process, in which input from the public may underscore specific areas of concern.

While China remains the primary source of manufacturing pirated Nintendo DS™ and Wii™ games, Korea has emerged as the leader in distributing illegal game files via the Internet. Despite aggressive anti-piracy actions taken by Nintendo, Brazil and Mexico remain saturated with counterfeit Nintendo software. Meanwhile, Paraguay and Hong Kong continue to serve as major transshipment points for global distribution of illegal goods.

Below is a summary of Nintendo's filing:

OVERALL: Nintendo recommends stronger laws in all countries against the circumvention of technological security measures. Video game pirates have developed DS game-copying devices and modification chips to target the security found in Nintendo's hardware systems and allow the play of counterfeit software or games illegally downloaded via the Internet.

CHINA: China must pursue criminal prosecutions against people involved in large-scale piracy operations. Nintendo works with Chinese authorities, who seized more than 1 million fake Nintendo products in China during the past year. But not one counterfeiter has been prosecuted.

KOREA: Nintendo supports the Korea-U.S. Free Trade Agreement, but suggests that it must be ratified immediately to address service providers who are profiting from the uploading and downloading of illegal Nintendo content. Korea is an important market for Nintendo, and Internet piracy is seriously affecting the growth of the video game industry in the country.

CENTRAL AND SOUTH AMERICA: During the past year, Nintendo assisted local authorities with more than 65 actions that resulted in the seizure of approximately 230,000 counterfeit Nintendo games in Brazil, Mexico and Paraguay alone. Despite Nintendo's efforts, the piracy levels continued to rise. Nintendo is calling for significant changes to laws and to the enforcement regimes in those countries.
