acekard 2i has stopped update for ages and i have checked for you, the official site cant be opened too . So, IMO, if all you want is playing nds games or homebrew on your NDS, then suggested you buy r4i gold 3ds from r4ids.cn like this one :
http://www.modchipfactory.com/wood-r4i-gold-3ds-flash-cart-for-3ds-xl-3ds-dsi-and-ds-lite-p-1.html , this is a very popular card, uses famous wood firmware,with a regular updating and top game compatibility, and the price is hard to beat at the same time.
