TwistedVoxel reported that the restriction requires system updates for SmileBASIC and Civilization VII. The report identifies the two games as part of the platform measure but does not explain how the update requirement works technically.
The publication characterized the change as making it more difficult for users to exploit the Switch 2 through SmileBASIC and Civilization VII. The supplied evidence comes from that single report; no official Nintendo confirmation is included.
TwistedVoxel published its report on November 12, 2026, according to the supplied source metadata. That publication date does not establish when Nintendo introduced the reported restriction.
