Dataminer Finds Hidden Challenge Modes in NSO Classics

A dataminer using the handle @luigiblood posted on a social network that hidden ‘challenge mode’ entries were added to the Nintendo Switch Online ‘Nintendo Classics’ libraries for NES, SNES and Game Boy. The entries appear as files or menu items tied to the NSO home menu but are not accessible to users.

According to the post, each challenge begins from a specific point in a game and defines distinct success and failure conditions. The description indicates short, mission-like scenarios rather than full-game sessions.

The discovery appeared in the run-up to a scheduled Nintendo Direct. Nintendo has not issued a comment and the entries remain inactive, leaving the feature unconfirmed.

The post reads: ‘challenges start from a specific point in select games, and each comes with its own unique success and fail states.’ The entries are currently visible only in the NES, SNES and Game Boy libraries grouped under Nintendo Classics; players seeking confirmation may watch the upcoming Nintendo Direct.
