Nintendo seems to have fired back over the Tears of the Kingdom leak by DMCAing popular Switch emulation tools

pcgamer.com:

First reported by GBAtemp(opens in new tab), it looks like Nintendo is aggressively responding to the Tears of the Kingdom leak(opens in new tab) by targeting key portions of the Switch emulation ecosystem, namely the Lockpick and Lockpick_RCM programs that dump Switch game decryption keys and allow emulators like Yuzu and Ryujinx to decrypt and open the game files.

Nintendo has just issued multiple DMCA takedown requests to GitHub, including for Lockpick, the tool for dumping keys from YOUR OWN Switch, which is absolutely ludicrous — pirates aren't gonna be sourcing keys from their own consoles!https://t.co/QePiLPTjmmMay 4, 2023

The first indication of this move came from developer and security researcher Simon Aarons(opens in new tab) on Twitter, who attempted to fork the Lockpick repository on Github (i.e. make a copy of the source files to iterate and experiment on them). Aaron received a copy of the DMCA request sent to GitHub over Lockpick and Lockpick_RCM, though there may be other projects affected. At the time of writing, Lockpick(opens in new tab) remains accessible on GitHub, though GBAtemp notes that there could be a grace period before the site acts on any takedown requests.

The alleged Nintendo takedown request shared by Aaron and another Twitter user, @llIllIIIlII1(opens in new tab), argues that «The reported repository offers and provides access to circumvention software that infringes Nintendo’s intellectual property rights,» and further asserts that «The decrypted keys facilitate copyright infringement by permitting users to play pirated versions of Nintendo’s copyright-protected game software on systems without Nintendo’s Console TPMs or systems on which Nintendo’s Console TPMs have been disabled.» I
