Hi, Need your help. I'm not sure if this is the correct platform. as anyone already knows, one of the recommended things to do before formatting/creating emuNAND is to back up all the data/content inside the SD card to PC. Mine is 4GB that also included Super Mario 3D Land preinstalled. The problem is i can copy the .sav data from gateway and also DCIM folder but when it came to copying 'Nintendo 3DS' folder, it became very slow and sometime error or 'not responding' that i cannot do the copying at all. Btw, this is my 1st time i try to backup the data. I am not sure whether it is the sd card reader faulty (and need replacement) or it is just the data/content inside 'Nintendo 3DS' that is restricted for copy function as I believe the preinstalled game data are stored inside. Never been to eshop as my firmware is at 4.4. I can still use the same card reader to write rom using the win32 imager. I also can still use the sd card in my 3ds xl for gateway mode saving and playing the preinstalled game. ATM, i do not have any other card reader available for troubleshooting. I have read it somewhere that the all the data inside the sd card can be backup easily by just copy/paste example for upgrading to a higher capacity sd card.
