Following the shutdown of Nintendo Network on April 8, 2024, two players by the user handles of Marioiscool246 and Fishguy6564 attempted to stay connected to the service in some form by activating online multiplayer in Mario Kart 7 and playing for as long as possible. The campaign, which originated as a way to determine how Nintendo Network functionality is disabled for a given title, used bots and a custom patch to keep the pair's 3DS systems connected and active.

While Marioiscool246's 3DS eventually froze after just over a month, Fishguy6564 remained live for substantially longer, with his own system not crashing until November 3, 209 days later. In doing so, he broke the record for the longest recorded time spent in post-shutdown online multiplayer, surpassing both the 25-day stretch held by Halo 2 player APACHE_N4SIR in 2010 and the 68-day Splatoon marathon conducted by Lcd101 earlier in 2024.
