I seem to have run into a problem with my acekards. I bought 3 of these for myself, my wife, and one of our sons. Over this past weekend, while at AnimeFest, I was in pictochat when everyone said that we should play MarioKart. When I went into my game and went to multiplayer, I noticed that I had no signal. I reset the DS and tryed again, but still nothing. I Tried my wife's and got the same problem. Can these not play with other? I have an AceKard 2, running the most up-to-date AKAIO, and using DS Lite any help? Note: Pictochat, and online updating works fine. Will test out online play shortly.
