Nintendo's anti-emulation campaign rolls on with a fresh barrage of DMCA notices to GitHub, targeting repositories for 13 Switch emulators and forks: Citron, Eden, Kenji-NX, MeloNX, Pine, Pomelo, Ryubing, Ryujinx, Skyline, Sudachi, Sumi, Suyu.

The filings accuse these projects of circumventing Nintendo's technological protection measures through unauthorized cryptographic keys, enabling the decryption and execution of illegal Switch game copies. GitHub granted recipients one business day to respond before potential disablement—a deadline some met by compliance, others by defiance.

Developer reactions reveal the pressure points: Citron's Zeph discontinued the project and vacated its Discord server; Ryubing's lead GreemDev stepped down for 'bigger things,' shifting to community maintenance on GitLab; Eden, however, hosts its source code off-platform and vows continued development for 'game preservation,' with founder Camille LaVey emphasizing community sustainment.

X and Reddit erupt in backup frenzies and DMCA abuse claims, with users mirroring repos amid whack-a-mole predictions—echoing 2024's Yuzu shutdown, Ryujinx settlement, and Switch 2's MIG Switch online bans. The timing, as Switch 2 ecosystems mature, suggests Nintendo fortifying against emulation encroachment before cracks widen. Nintendo's ledger balances enforcement against resurgence; for now, the scales tip toward takedowns.
