A lawsuit has been filed by Capcom, Nintendo and 53 other DS software manufacturers against four companies importing and selling R4 Revolution for DS devices.
Filed with the Tokyo District Court, the companies are seeking an injunction to prevent distribution of the piracy enabling devices, and compensation for their losses as well.
In February, the court ruled in favour of the game companies and made it illegal to import and sell the R4. However, in an official statement Capcom said there had been no sign of their disappearance from the market.
Despite repeated warnings requesting their discontinuation, the publisher noted that in many cases vendors were ignoring requests, forcing the renewed legal action.
"We are expecting the entire society, including users, to recognise that our company and other software manufacturers have extremely sustained damages from proliferation of illegal instruments such as the Game Copying Devices," Capcom said in the statement.
"The computer industries have sustained serious damages because of those vendors, and we expect to influence the society to eliminate such illegal instruments from the market."
