Download games from freeShop, but only play for couples minutes then come"SD card removed". Have tried Htestw, re-format by GUI & by Nintendo recommended (SD card formattor) still not working Rang Nintendo & they said maybe SD reader problem, but to make sure that to test with couple Sd cards. My current Sd have contains of stuffs about 17GB, and only have some 4GB Sd at home. Is there a way to test with 4GB card (included the one that Nintendo included in the box ).
