Nintendo Zone was a download service and an extension of the DS Download Station. Users could access content, third-party data, and other services from a hotspot or download station. The service had demos of upcoming and currently available games and may have location-specific content. When the service debuted, users could also connect to the Nintendo Wi-Fi Connection and DSi Shop.
The Nintendo Zone Viewer application allows the Nintendo DSi and 3DS to detect and use the Nintendo Zone service. This application has been discontinued worldwide, but all other Nintendo Zone functionality remains.
