Two owners of a Los Angeles game store and a third man face a up to five years in prison on charges filed Monday in a federal copyright infringement case for selling modified Xbox game consoles, prosecutors said. The modifications allowed the machines to play pirated video games, they said.

The three men are being accused of "conspiring to traffic in a technology used to circumvent a copyright protection system and conspiring to commit criminal copyright infringement," in violation of the Digital Millennium Copyright Act, according to a statement from the U.S. Attorney's Office for the Central District of California.

During the investigation, undercover agents with U.S. Immigration and Customs Enforcement paid $265 to have a modification chip, a hard drive and 77 pirated games installed on an Xbox, according to the criminal complaint.
