[UPDATE] Dolphin's release on Steam indefinitely delayed after Nintendo sends cease & desist order to Valve
[UPDATE] The entry on the Dolphin blog has been changed slightly to more accurately reflect the situation. While their original post yesterday said Valve had received a DMCA takedown notice from Nintendo, the revision now claims it is a cease & desist order citing the Anti-Circumvention provisions in the DMCA.
Pierre Bourdon, a former member of the Dolphin team, has claimed on Mastodon that the order originated with Valve. He reports that Valve reached out to Nintendo regarding Dolphin, and Nintendo issued the C&D in response. If this is the case, it would impact Dolphin's available options for recourse as Valve retains the right to remove listings from their storefront. It also means, however, that Nintendo is not pursuing legal action against the Dolphin team right now.
[ORIGINAL STORY] Back in March, the team behind the Dolphin GameCube/Wii emulator announced that they would be bringing Dolphin to Steam sometime in the second quarter of 2023. However, the release seems to be indefinitely delayed after Valve received a DMCA notice from Nintendo. Posting on their blog today, the team announced that Steam had contacted them to let them know of the takedown notice and that the page will be down "until the matter is settled." The team is currently investigating their options and promise a more in-depth update as soon as possible.
PC Gamer claims to have reviewed the document, dated today, May 26. It reads, in part:
Because the Dolphin emulator violates Nintendo’s intellectual property rights, including but not limited to its rights under the Digital Millennium Copyright Act (DMCA)’s Anti-Circumvention and AntiTrafficking provisions, 17 U.S.C. § 1201, we provide this notice to you of your obligation to remove the offering of the Dolphin emulator from the Steam store.
The Dolphin emulator operates by incorporating these cryptographic keys without Nintendo’s authorization and decrypting the ROMs at or immediately before runtime. Thus, use of the Dolphin emulator unlawfully 'circumvent a technological measure that effectively controls access to a work protected under' the Copyright Act.
Nintendo is attacking the Dolphin Emulator under the DMCA's Anti-Circumvention provisions, citing the inclusion of the Wii's common key in Dolphin's source code. Nintendo argues that because the common key allows Dolphin to decrypt data, it allows users to illegally circumvent measures put in place to control access to works protected under the Copyright Act - in this case, GameCube and Wii games.
Dolphin is somewhat unique in distributing this key already built in to its source code, as most emulators require the end user to provide a key or BIOS on their own. Emulator frontend RetroArch has also been added to Steam but, contrary to Dolphin, hasn't been the target of DMCA attacks by Nintendo, likely because its builds and cores require external BIOS and key files not found within their source code.
As of now, it appears as if this only affects Dolphin Emulator's upcoming release on Steam. It is still available to download on the official website.
