I'm currently using superkey and supercard sd on my DSL, and the work great. My only issue is trying to get game sharing to work with some games. NSMB and Mario Kart DS to be exact. I can't get the game share to work. I've gotten Tetris DS, Brain Age, and Magnetika working with game share, but not the two former games. Has anyone tried game sharing with flash carts ? I'm using the latest supercard software and latest kernel.
