Nintendo is using its legal muscle to take ROM sites down, apparently one at a time if it has to. As reported by Polygon, the Switch maker yesterday filed suit against the people behind RomUniverse, a site prominently offering ROMs and ISOs of games for dozens of current and older game systems, including the Switch and 3DS.
The suit alleges that in addition to violating Nintendo's trademark and copyrights, the site has for the last decade been profiting off the distribution of unauthorized copies of games by selling a premium membership that allowed users to download larger numbers of ROMs at higher speeds.
