Hi, I've had this 4g sdhc sandisk sd card and I was wondering if I can play games from it on my dsi. I've had this sd card before I bought my dsi so I was wondering if I could get out of buying another one. Also, could someone please tell me how to format games on the sd card? I've been trying t look around but all the links I found were broken. Thank you. Also, when I have my sd card in, I can take and save pictures on my sd card... I just don't know what the problem is... Can anyone please help me???
