A story about this new card for the DS was posted on Gizmodo the other day. http://www.maxconsole.net/?mode=news&newsid=9036 Pretty intriguing I would say. I hope to see some reviews of it in actual use soon.
I already mentioned this device in this thread: http://forums.afterdawn.com/thread_view.cfm/378302 The thread was for the DSLink, but the news of the DS Extreme came soon after so is mentioned later on in the thread.
Ah I missed that. I'm glad there is a bit of info on this new solution. I'm still waiting for someone to guinea pig it though mr_hanky are you volunteering?
I'm happy to try it out - providing someone else pays I'm short on cash at the moment, and am going to university soon so will not have the extra cash to spend on things like this :-(
