SOLVED! THANKS! I just got my Acekard 2i in the mail. Website description said it would be working out of the box. Of course they were wrong, I put in my Micro SD in it with games and the cartridge isn't showing up. I believe I have to update the cart with firmware or atleast put some kind of firmware on it. I only have access to a 3DS so I hope I don't need any other DS to get it working. Any help would be greatly apprecitated!
