"Pretendo: Keeping Nintendo's Online Games Alive Despite Server Shutdown"

Nintendo has shut down online services for Wii U and 3DS, but a fan project called Pretendo is working to keep them alive by recreating Nintendo Network using clean-room reverse engineering. Although still a work in progress, Pretendo aims to provide continued access to online features for Nintendo hardware long after the closure of Nintendo Network. The shutdown has led to community efforts like Team 0% completing every Mario Maker level, while fans mourn the end of an era for the beloved gaming platforms.
