Allegations about the sale and distribution of illegal modification chips and copyright circumvention devices for the popular consoles and others included 32 search warrants in 16 states, said the federal Immigration and Customs Enforcement. Illegal chips and other devices used on gaming consoles violate the Digital Millennium Copyright Act of 1998. Sales of counterfeit or illegally obtained games costs the industry about $3 billion a year globally, not including Internet piracy, the Entertainment Software Association, a trade group, estimates.
