If I play Mario Kart DS on a 3DS, will WiFi multiplayer still be available?

I've had a DSi for almost an entire year now, and on May 20th of this year, Nintendo discontinued WiFi and multiplayer matchmaking on games.

As of May 20, 2014, certain online functionality offered through Nintendo Wi-Fi Connection is no longer accessible. The discontinued services include online play, matchmaking and leaderboards for many Wii, Nintendo DS and Nintendo DSi games.

However, as far as I know, the Nintendo 3ds has WiFi functionality. If I played Mario Kart DS on a 3DS, would I be able to play multiplayer Mario Kart DS, or are the services discontinued for the entire game?

Solution 1:

For online multiplayer, unfortunately no.

All DS titles use the old matchmaking system. Even though the system itself is a 3DS, the game will still attempt to connect to the old servers, which are no longer operational.

Local multiplayer should continue working.
