My 3DS is the latest version (6.1.0-11U), but whenever I try to play my R4(Dual-Core 2013) card, it says "An error has occurred. Press and hold the power to turn the system off. Please refer to the operations manual for details." Could someone tell me the issue please? [EDIT] 4/5/13 This issue is solved! Update the firmware of the card on a DSi or DS lite.
