How To Register A Console On Wiimmfi

Nintendo announced that Nintendo Wi-Fi Connectedness would be discontinued on May 20, 2014. This impacted all Nintendo DS and Wii games with online features that were directly using Nintendo WFC, which included Mario Kart Wii. Wiimm had been analyzing the Mario Kart Wii network traffic since November 2012, and had already written a helper tool named mkw-ana. And so he decided, together with other people, to create the Wiimmfi Project (formerly Wii-Server Project) to supplant Nintendo's servers for Mario Kart Wii and for other games, if possible.

wiimmfi.de

wiimmfi.de replaces nintendowifi.cyberspace in games. All games must apply this new domain and change https to http (see below).

The domain wiimmfi.de was registered by Wiimm for this project. If Wiimm discontinues this service at any time in the future, he will give abroad the domain, the software and the data base content.

State of the Project

On May 10 2014, ten days before Nintendo close down their NAS and disconnected themselves from GameSpy, Wiimm released Wiimmfi-Patchers. Since that date, Wiimmfi was publically usuable. At start, the server merely supported Mario Kart Wii, including the unlike Custom Track Distributions. All the same, more games have been enabled, tested, and are now fully supported.

The game lists also contains data about bug.

Connecting to Wiimmfi

Wii games must exist patched to access Wiimmfi, equally Nintendo Wi-Fi Connection originally used SSL for login. However, a variety of patchers exist for Wii games:

CTGP-R automatically includes Wiimmfi back up in-app, with no setup required.
Motorcar Wiimmfi Patcher is a home-brew app that will automatically patch Wii discs when launched (however, it is required to launch the app every time) - this app can also be accessed past setting the Wii'southward DNS to 95.217.77.151 and launching the WC24/Wii Shop Channel license agreement.
Car WiiWare Patcher tin patch nearly WiiWare WADs to allow enable Wiimmfi access.
Wiimm's Disc Patcher can permanently patch disc images.
Updated USB Loaders can also automatically patch USB images for Wiimmfi - recent versions of USB Loader GX and WiiFlow can automatically patch for Wiimmfi using a Individual Server selection.

Implementation

Wiimm originally implemented the server in PHP, so that the servers were created quickly. From the showtime of development, it was known that the servers must be ported to C/C++ to improve performance. While developing, in that location were issues due to using PHP, and 2 servers have thus been ported to C.

NAS

NAS is the Nintendo Authentication Server. The Wii used naswii with HTTPS, and the DS used nas (which supported HTTP) with HTTPS. They are interchangeable. On Wiimmfi, the server is implemented using APACHE2 and PHP5. At the moment, logins are accustomed with old and new profiles. New savegames ship a request to get their unique console nickname from the server.

GPCM

When entering the WFC, the Wii connects to GPCM using TCP. The connexion is closed upon leaving WFC. The server is used for full general maintenance and for bulletin exchange betwixt the clients.

It is currently implemented every bit PHP script. The interprocess advice (transferring messages) is implemented with UNIX sockets. To improve the performance and to allow a better interprocess communication, a C-server was written. It is all the same in development and supports a model with supervisors and workers. Since March 2016, the new server is in utilise at Wiimmfi's exam server.

GPSP

GPSP is used to recall information nearly friends. The Wii connects frequently using TCP. Nintendo's GPSP server was used to recall the profile_id and nick pairs before shutdown.

On Wiimmfi, GPSP has been implemented as PHP script.

Master

Main listens on port 27900 via UDP. Games transport condition records to MASTER. Chief stores them into a game specific tabular array, where other clients can retrieve the information using MS (see adjacent point).

At the beginning, MASTER was implemented as PHP script. In September 2014 it was replaced past a giant server written in C to ameliorate functioning. The new Primary reduces was optimized and reduces queries to the database by ~90%.

MS

MS is used by the clients to call up data about other online clients. The query is similar to an SQL query, with select, where and limit clauses. The reply is encrypted by a game specific secret.

At the outset, MS was implemented every bit PHP, just piped the response through an encoder written in C. In January 2016, it was integrated into the MASTER server (written in C).

NATNEG

NATNEG is used to establish a connexion between two players, both of whom are behind NAT. The clients simply communicate with this server when they attempt to connect to another player.

NATNEG has been implemented in C. Every bit it was the first C tool, it has an open second port to send special UDP packets for MS with the faked sender address of MASTER.

SAKE

SAKE is used for data exchange — files or records can be uploaded to the SAKE server. This is used for friend Mii substitution in Mario Kart Wii, along with ghosts.

SAKE has been implemented in PHP, and tin transport/receive ghosts and Miis, along with other games' information.

RACE

RACE is used for downloading competitions and rankings in Mario Kart Wii. RACE has been implemented in PHP, with competition support added past Leseratte (with help from Billy), which is now fully working.

GAMESTATS

GAMESTATS is for game rankings/leaderboards. There are two versions of it; HTTP and TCP. Sepalani has implemented both in Python, the former is a near-consummate implementation. Games like Mario Strikers Charged and Dr. Mario Online Rx utilise GAMESTATS.

DLS1

DLS1 is a server for game file downloading. Wiimmfi runs a PHP version which has no files (due to copyright reasons), simply a third-political party DLS1 server is also ran for a lot of NDS/Wii games for their own files. This server is unused by Mario Kart Wii.

Using old profiles

For each profile, there exists a profile ID and nickname pair. Merely the Wii and the server they were created on knows both of them. At login the Wii sends the nickname and the server answers with the related profile ID. If the profile ID is wrong, the game will abort the login with error code 60000.

There is only 1 way to use your old profiles with Wiimmfi: At the beginning of the project, when the old GameSpy servers were bachelor (which shut downwards on July 25th, 2014), Wiimm retrieved two.ix million pairs. If your profile was retrieved, it is possible to use your onetime license on Wiimmfi; otherwise, you will demand to create a new friend code (Mario Kart Wii now automatically does this with the latest patch)
