I just bought a ndsi from my friend, but without accessories . I wanna to buy a card ,when I went to the shop ,I found there are so many kinds of different cards to choose. I am confusing that which one to choose . The boss advised me to pick the Acekard up, I don't know if it is right. If the Acekard is the best choice , how can other cards live ? Can any body tell me the difference between them ?? Any insights will be appreciated.
