In the wake of its one-week lawsuit targeting the Yuzu Switch emulator,
Nintendo is back to clean up the house. The company has just shut down
around 30 GitHub repos offering circumvention tools with attempts to
evade liability given short shrift. One Nintendo takedown notice makes
it clear that, even when people link to a third-party site that hosts
tools available via different links, it still amounts to trafficking in
circumvention devices under the DMCA.
[4]nintendeal2 It took less than a week for [5]Nintendo’s lawsuit
against the company behind the Yuzu Switch emulator to have the desired
effect.
After agreeing to hand over [6]$2.4m to Nintendo while complying with
the terms of a broad injunction, Tropic Haze LLC evaporated in all but
name and its developers drifted away into the night, apologetic and
presumably penniless. At least, that’s what the paperwork and
subsequent announcement implied, give or take.
Nintendo: We’re Back
With plenty of time in the interim to clone the Yuzu repo, many people
did, purely for old times’ sake. Others still involved with projects
related to Switch hacking and emulation had decisions to make, at least
based on the theory that things had somehow changed. Some took evasive
action, others took steps towards limiting liability, some appeared to
do nothing; the usual mixed bag of responses following a big shutdown
event.
That Nintendo was not too far away comes as zero surprise. Among the
targets this week were over 25 GitHub repos offering Sigpatch-Updater,
a tool to update SigPatch files created by developer iTotalJustice. In
conjunction with a modded console, SigPatches bypass signature
verification when games are downloaded digitally, a red line for
Nintendo.
“The necessity of SigPatches to operate pirated copies of Nintendo’s
video games is widely discussed in groups dedicated to modifying
(hacking) the Nintendo Switch console,” Nintendo’s lengthy DMCA
takedown notice reads.
“For example, [redacted by GitHub], a site that instructs users how to
modify their Nintendo Switch console, states that ‘Signature patches or
SigPatches allow your device to bypass signature checks performed by
[private] for installed titles,” Nintendo notes, before adding the
following:
Trafficking in circumvention software, such as SigPatches, violates the
Digital Millennium Copyright Act of the United States (specifically, 17
U.S.C. §1201) (the “DMCA”), and infringes copyrights owned by Nintendo.
Nintendo Gets Reacquainted With iTotalJustice
Back in the summer of 2022, a previous [7]set of DMCA notices included
one that targeted a repo operated by iTotalJustice. Before it was taken
down, the repo contained actual SigPatches and Nintendo makes the same
allegation here, albeit with additional detail that broadens the scope
beyond actual hosting.
“With the iTotalJustice repository reported in this current notice,
iTotalJustice is attempting to evade Nintendo’s enforcement efforts by
providing SigPatches via a link to a third-party website ([private]),
rather than including SigPatches in the repository itself,” Nintendo
writes.
“The link is accompanied by the statement ‘The patches are downloaded
from a new host. Huge thanks to them!’ Several of the forks reported in
this notice also link to the third-party website [private] to provide
SigPatches.”
Repos removed for trafficking in circumvention devices[8]
sigpatch-repos
According to Nintendo, a hyperlink posted to a website that links to
another website (not even to the SigPatches themselves), which in turn
offers the SigPatch files for download, is illegal under the DMCA when
the linker demonstrates knowledge and intent.
“Linking to circumvention software is considered ‘trafficking’ in
violation of the DMCA where, as here, the party responsible for the
link (a) knows that the offending material is on the linked site, (b)
knows that the linked material is circumvention technology, and (c)
maintains the link for the purpose of disseminating that technology,”
the company explains, citing [9]17 U.S. Code § 1201.
Takedown Notice Targets Lockpick
A second notice targets a piece of software known as Lockpick. This
circumvention tool bypasses Nintendo’s security (Technological
Protection Measures, or TPM) on the Switch console, providing access to
cryptographic keys, including product keys, which are then decrypted
and extracted.
This allows pirated Switch games to be played on modified consoles or
if users prefer, on emulators like Yuzu. Nintendo states that Lockpick
is illegal under 17 U.S.C. §1201 and those who facilitate access to it,
under the conditions previously outlined for SigPatches, similarly
traffic in circumvention software, contrary to the DMCA.
These won’t be the last notices of their type from Nintendo and another
Yuzu-style lawsuit can’t be ruled out either. In an article
[10]published by Ars earlier this week, the developers behind apparent
Yuzu successor ‘Suyu’ outlined a few of their lawsuit-avoidance
strategies.
After confirming that Suyu is pronounced “sue-you (wink, wink)” the
strategy as outlined doesn’t really contain anything that might
discourage a fairly litigious Nintendo even slightly. Having read the
[11]Contributor License Agreement, it can’t be ruled out that the
people behind this have a dark sense of humor.
