Switch 2 Day 1 Update Enables Backward Compatibility

The Nintendo Switch 2 requires a crucial day-one update to fully activate its core functionalities, including backward compatibility with original Switch games.

The highly anticipated console launches today in regions where it's already June 5, 2025, with Nintendo releasing its essential system update simultaneously.

This mandatory update enables compatibility with most Switch 2 titles, original Switch games, online multiplayer, Virtual Game Cards, and physical software requiring digital downloads.

While expected by many Nintendo enthusiasts, early adopters confirmed the console requires significant initial updates for full functionality.

Most players should easily complete this download, though those eager to play immediately should account for installation time.

The update likely reflects Nintendo's continued firmware refinement during manufacturing several months ago.

This strategic approach also helped maintain secrecy about Switch 2 features until launch day, limiting premature exposure despite some units surfacing early.

The patch notes amusingly highlight the fundamental update enabling the console's primary purpose: gameplay functionality.
