Scratch

Basically, I have a very old DS, and I've always wanted to find out how to access online play. For the first time today, I was finally able to reach an Internet access point. Of course, with the Wii and 3DS, virtually (no pun intended) nobody visits the Wi-Fi lobbies for DS or DSi games. 

I'm looking for people to play with on my DS.

Preferred games would be Sonic Rush, New Super Mario Bros., and Mario Kart DS.
