Nintendo’s attitude toward ROM releases—either original games’ files or fan-made edits—has often erred on the side of litigiousness. But in most cases, the game producer has settled on cease-and-desist orders or DMCA claims to protect its IP.

This week saw the company grow bolder with its legal action, as Nintendo of America filed a lawsuit (PDF) on Thursday seeking millions in damages over classic games’ files being served via websites.

The Arizona suit, as reported by TorrentFreak, alleges “brazen and mass-scale infringement of Nintendo’s intellectual property rights” by the sites LoveROMs and LoveRetro. These sites combine ROM downloads and in-browser emulators to deliver one-stop gaming access, and the lawsuit includes screenshots and interface explanations to demonstrate exactly how the sites’ users can gain access to “thousands of [Nintendo] video games, related copyrighted works, and images.”
