In context: Following legal battles against multiple Switch emulators and modding platforms, Nintendo has recently clarified its stance on emulation and piracy. While the company acknowledges its limitations in combating programs like Yuzu, a recent arrest in Japan for selling modified devices loaded with pirated games has brought Nintendo's aggressive litigation strategy into sharper focus. A 58-year-old man from Ibaraki Prefecture, Japan, was arrested for selling modified Nintendo Switch consoles designed to play pirated games. According to Japanese media, this marks the first arrest in the country for circumventing the portable device's copyright protection.Fumihiro Otobe, a transportation worker from Ryugasaki City, was accused of soldering hardware modifications onto secondhand Switch circuit boards to enable the use of pirated games. He allegedly resold these modified consoles for 28,000 yen (approximately $180) each and pre-installed 27 pirated games on them.Upon his arrest, police discovered four modified units in his possession. Otobe reportedly confessed, saying, "I was curious if people would think I was great for selling modified machines."Nintendo is notorious for its relentless pursuit of pirates, though it typically relies on civil lawsuits rather than criminal prosecution. The company's head of intellectual property recently elaborated on the legal framework that likely influenced Otobe's arrest.At the annual Tokyo eSports Festa last week, Nintendo's chief patent attorney, Koji Nishiura, acknowledged that emulators are technically legal. However, he emphasized that distributing copyrighted software through these emulators remains illegal. Notably, last year's litigation threats against Switch emulator developers Yuzu and Ryujinx prompted them to temporarily shut down, though neither case went to court. // Related StoriesYuzu's developers admitted the emulator was primarily used to distribute copyrighted software a practice Nishiura considers illegal. Moreover, bypassing Nintendo's copyright protection mechanisms constitutes a violation of intellectual property laws. These factors likely played a significant role in Otobe's arrest.Although Nishiura's comments only concern Japanese law, the US has similar regulations regarding copyright dodging. For example, last year Nintendo sued the operator of a business called Modded Hardware, which offered Switch flash carts, hacked consoles, dumping devices, and modding services. The lawsuit accused the company of selling systems preloaded with pirated games.If Otobe's arrest signals that Nintendo is escalating its anti-piracy campaign, this renewed vigilance aligns with the upcoming release of the Switch 2. Nintendo recently announced the updated console, which will feature a larger screen and significant graphical improvements. While an official release date has yet to be confirmed, more details are expected to emerge in April.Typically, consoles become targets for emulation only after they are considered retro. However, Yuzu was capable of running Nintendo Switch games less than a year after the console's 2017 launch. Whether Nintendo can prevent a similar scenario for the Switch 2 remains uncertain.
