Nintendo's DMCA Notice Gets the Dolphin Emulator Pulled From Steam
Dolphin was days from launching on Steam when Nintendo sent Valve a DMCA cease-and-desist. Valve pulled the listing rather than take a side — and Dolphin's Steam release has been in limbo ever since.
On May 27, 2023, the Dolphin emulator team announced that its long-anticipated Steam release — the same project that years earlier became the first emulator to run commercial GameCube games — was “indefinitely postponed” after Nintendo sent Valve a DMCA-based cease-and-desist notice.
What happened
Dolphin had been listed on the Steam store page since March 2023 ahead of a planned release. According to Dolphin’s own developers, Nintendo’s notice to Valve argued that Dolphin violated the DMCA — specifically objecting to Dolphin’s inclusion of code to decrypt commercial Wii game discs, which Nintendo characterized as circumventing a copyright protection measure. Rather than contest the notice or wait for a resolution, Valve removed Dolphin’s store page from Steam entirely.
Dolphin’s own response
In a blog post on their site, the Dolphin team stated they disagreed with Nintendo’s legal characterization and pointed to prior case law — including Sony v. Connectix — that has historically supported emulation as a legitimate technique distinct from piracy. Dolphin itself continued to be distributed as free, open-source software directly from the project’s own website, unaffected outside of the Steam listing specifically.
Why Valve’s choice mattered
Valve’s decision not to fight Nintendo’s notice, and instead comply by pulling the listing preemptively, meant the dispute was resolved by platform policy rather than by a court ruling — leaving no new legal precedent behind, unlike the Ninth Circuit’s earlier decisions in emulation cases. It also illustrated a distinct and increasingly common enforcement pattern: rather than suing an emulator’s developers directly, a rights holder can act at the distribution-platform layer instead, achieving a similar practical outcome without going anywhere near a courtroom.
