Dolphin emulator removed from Steam after Nintendo DMCA

Dolphin, the extremely popular video game emulator, was set to have a PC version on Steam, but it's since been delisted from the platform. On May 27, Dolphin's developers said its port was "indefinitely postponed" as the result of discussions between Valve and Nintendo. 

"We were notified by Valve that Nintendo has issued a cease and desist citing the DMCA against Dolphin's Steam page," they wrote, "and have removed Dolphin from Steam until the matter is settled."

Dolphin has been available for years as an open-source project, and was listed on Steam back in March. With an official store page (and presumably, priced at little to nothing), its profile would've been greatly boosted as a result. Emulator interest has reportedly grown thanks to Valve's Steam Deck handheld. 

Nintendo's letter to Valve claims Dolphin uses "cryptographic keys without Nintendo’s authorization and decrypting the ROMs at or immediately before runtime." Doing so for individual games possibly violates Nintendo's intellectual property rights, which is what the publisher is using as its basis to stop Dolphin.

An intellectual property lawyer speaking to PCGamer explained that Nintendo's DMCA means it "considers Dolphin to violate the DMCA and should it be released on Steam, Nintendo will likely take further action." Meaning that Valve could likely end up on the hook for any legal troubles, similar to what recently happened with Sony in Austria. 

Dolphin's developers said they're currently "investigating our options, and will have a more in-depth response in the near future. We appreciate your patience in the meantime."

Various companies have made efforts to stop emulation where it can, but few work as hard at it as Nintendo.
