Is Mario & Luigi: Bowser’s Inside Story + Bowser Jr’s Journey Update 1.1 completely free?

Do I need the base game to use this update?

Match the update to your base game region. If your base game is EUR, download the EUR update; if it is USA, download the USA update. Mixing regions will not work.

Will installing the update erase my save data?

No. Applying the 1.1 patch does not remove your existing save files. Your progress remains intact after installation.
