In the wake of Yuzu's $2.4 million settlement with Nintendo, the Mario maker has redoubled its work to fight Switch emulation, but these efforts don't involve any argument that emulation itself is illegal. Instead, Nintendo is relying on an extremely specific part of a decades-old copyright law to kill a load of software that can be used to pirate Switch games.
Earlier this month, Nintendo issued a pile of takedown notices to GitHub under the Digital Millennium Copyright Act, or DMCA, as TorrentFreak reports. Two pieces of software have been the primary targets in the company's crosshairs: Lockpick and SigPatch-Updater. Lockpick is a piece of software that can extract cryptographic keys from Switch games, while SigPatch-Updater allows users to bypass the verification process for digital games. Neither one of them is new, and both have been playing a game of DMCA whack-a-mole with Nintendo for ages.
