How to Play Multiplayer Mario Cart on the Nintendo DSby Jess Kroll ; Updated September 22, 2017
"Mario Kart" for the Nintendo DS uses the system's built-in wireless LAN to connect with nearby systems for multi-player races of up to eight people or online with up to four. Players can use a single DS card to download the information from one game, or multiple DS cards, even if they don't own a copy of the game themselves. Once the information is downloaded, it will be stored on the system until the DS is turned off.
