"However, in the U.S. it has been illegal since 1983 for a user to create their own backups of video game ROMs onto other cartridges. This was decided in the court case of Atari v. JS&A. JS&A manufactured a "game backup" device that allowed users to dump their Atari ROMs onto a blank cartridge. JS&A argued that the archival rule allowed for this. The court disagreed, noting that ROM media was not subject to the same volatility as magnetic media (for which the law was created). Thus, not being so relatively vulnerable, ROMs were not applicable under section 17 USC 117(a)(2)."
