Latest Twitter Messages from BroadOn that 3DS EEPROM Savefile can be encrypted/decrypted by 3DSaveTool.
It seems that they have found the major flaw in QR Image Handler, and released 3DSavetool to find the XOR key used for encryption of 3DS EEPROM savefiles.
The EEPROM of 3DS cards is encrypted via an unique per game 512byte XOR'key, and it seems that 3DS ROMs is using that as well.
3DSaveTool has been updated into Version v0.2b.
