So really, my question is the topic title. I remember for the Gamecube, there was tunneling software. You could plug your 'cube into your PC via cat-5, run the software, and it would hop onto the net and connect to any other people running the software to turn multiplayer offline games (i.e. mario kart) into an online based game, but tricking the 'cube into thinking its connected directly to another 'cube. Has there been any developments with this on the DS front? I would LOVE to hop on and play some Soma Bringer with some of you freaks around the world. Or maybe some other wonderful non-net-based multiplayer DS games. Lemme know, thanks!
