I used to do this when I first got my DS, and play the original E3 2005 techdemos like submarine and table hockey :)
A compatible wifi card was one of the first things I got as an "accessory" to my DS. As people have said before this guide is well over a year old....
are there even new demos being released on the net now?
This is old and outdated. There are much easier ways of getting homebrew onto your DS via WiFi.
Ok i am now using a Belkin that was on the list but when i try to install the DS driver from the location of the DS Driver it doesn't work and says The wizard could not find a better match for your hardware than the software you have currently installed. Anyone know how to solve this problem?
