The ds online scene was shut down by nintendo when they announced the end of Wii and Ds online. At least, that’s what most people think. The community still has the flame of life burning, despite nintendo attempting to snuff it out. If you change the DNS settings, you can access online again. Will there be something similar for the 3ds games?
that will come with time.
