3DS and Wii U servers officially die in 2024, but fans have already spent years building their replacements

gamesradar.com:

Nintendo has announced its plans to shut down servers for the Wii U and 3DS in April 2024, but fans have already been working on a massive replacement in the Pretendo Network service.

Pretendo has been in development for ages, and it aims to offer a free, open-source, alternative to the official Nintendo Network for Wii U and 3DS servers. Groups of developers are working on building servers to accommodate every single game or console feature that once relied on the Nintendo Network, from the Miiverse and console-level friends lists to a wide variety of games both big and small.

These unofficial servers support real consoles that've been hacked to run homebrew applications, and Wii U enthusiasts can use the Cemu emulator to connect to these servers on PC. The big thing to be aware of is that all these individual features are being worked on by different groups of developers, which means there's no clear ETA one when it'll all be done.

For now, Pretendo is still in closed beta, so you can only get access through selection by a development team, or through a donation to a project. However, Pretendo does often hold open betas, and a comprehensive open beta is planned for the month of December. For now, Wara Wara Plaza - the part of the Wii U menu where random Miis from online wander around - is currently open to everyone, so you can test out at least one of Pretendo's features for yourself.

With news of the official servers shutting down, interest in Pretendo is naturally pretty high, and the devs say they're adjusting
