Can someone please check the following. There have been some people with issues as it pertains to the WIFI features and an R4.... I would like to know, as would some others I'm sure. Try... DS to DS dual cart (r4 and original) DS to DS single cart (r4 and ds) [download play] DS to WFC (online play) If you have these titles, please try them also make note if any of the units are flashed or not as it could have an effect. Metroid Prime Tetris DS Mario Kart Animal Crossing Tony Hawk American SkateLand There are others.... I would hate to think that the WFC was not working with the R4... Thanks.
