Pretendo Network

About us

Pretendo is an open-source project that aims to recreate Nintendo Network for the 3DS and Wii U using clean-room reverse engineering.

As our services would be both free and open source, they can exist long after the inevitable closure of Nintendo Network.

Frequently Asked Questions

Here are some common questions we're asked for easy information.

What is Pretendo?

Pretendo is an open source Nintendo Network replacement that aims to build custom servers for the Wii U and 3DS family of consoles. Our goal is to preserve the online functionality of these consoles, to allow players to continue to play their favorite Wii U and 3DS games to their fullest capacity.

How do I use Pretendo?

Pretendo is currently not in a state that is ready for public use. However, once it is you will be able to use Pretendo simply by running our homebrew patcher on your console.

Does Pretendo work on Cemu/emulators?

Pretendo is designed for the Wii U and 3DS hardware at heart; at this time the only emulator for these consoles with NN support is Cemu. Cemu does not officially support custom servers, but it should still be possible to use Pretendo with Cemu.
Pretendo does not currently support Cemu.

Will Pretendo support the Wii/Switch?

The Wii already has custom servers provided by Wiimmfi. We currently do not wish to target the Switch as it is both paid and completely different to Nintendo Network.

Will my existing NNIDs work on Pretendo?

Sadly, no. Existing NNIDs will not work on Pretendo, as only Nintendo holds your user data; while an NNID-to-PNID migration is theoretically possible, it would be risky and require sensitive user data we do not wish to hold.

Do you know when <feature/service> will be ready?

No. Lots of Pretendo's features/services are developed independently (for example, Miiverse may be worked on by one developer while Accounts and Friends is being worked on by another) and therefore we cannot give an overall ETA for how long this will take.

If I am banned on Nintendo Network, will I stay banned when using Pretendo?

We will not have access to Nintendo Network's bans, and all users will not be banned on our service. However, we will have rules to follow when using the service and failing to follow these rules could result in a ban.

Will I need hacks to connect?

Yes, you will need to hack your device to connect; however, on Wii U you will only need access to the Homebrew Launcher (i.e. Haxchi, Coldboot Haxchi, or even the web browser exploit), with info on how the 3DS will connect coming at a later date.
