Recmpilation seems like an incremental advance relative to the high-quality Switch emulation we already have.

Given the continuing success of the Switch 1 even after such emulators existed, I doubt this will pose a serious problem for Nintendo.

Best case scenario, it will lead Nintendo to reevaluate their exclusivity policies, as I'd be willing to bet an official TotK iPhone port would sell very well in spite of a vibe coded alternative.
