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?
Yes. The 1.1 update is a patch, not a standalone game. You must have the base CIA of Mario & Luigi: Bowser’s Inside Story + Bowser Jr’s Journey installed on your 3DS for the update to apply.
Which region should I download, EUR or USA?

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.

You need a Nintendo 3DS with custom firmware and a CIA installer such as DevMenu, BigBlueMenu, or FBI. Place the .cia file on your SD card and install it through the tool.
