Nintendo fans managed to preserve a good portion of game content on the 3DS and Wii U before the servers were shut down. On April 8th, Nintendo shut down the servers for Nintendo 3DS and Wii U, removing all online capabilities.

The SpotPass Archival Project aims to ensure that this data is accessible in the future, even without access to the online servers or the 3DS and Wii U eShop.
