Do you remember the Nintendo Zone service? For those who don't or weren't playing games back then, the Nintendo Zone download service was an extension of the DS Download Station where users could access content, third-party data, and other services from a hotspot or download station. You would find these Nintendo Zone distribution spots in locations like retailers, and you could connect to them with your DS to grab demos, trailers, and more.
The video above shows us the actual hardware Nintendo eventually used for Nintendo Zone distribution. Believe it or not, these units had just one touch screen, a cartridge slot, and that's about it. They would download data from Nintendo, and then send it out to local users. Get a much closer look at the device and how it worked in the video.
