Update:

Since firmware 2.0.0-4 Nintendo introduces a new way of encryption (might be a fix for the exploit above). The xorpad seems to repeat in the file but not every 0x200 bytes. so for now it is unknown how to decrypt the newer save files.

With system version [[2.0.0-4]] the system now uses a different CTR method, which fixed the above flaw. The xorpad seems to repeat in the file but not every 0x200 bytes. So for now it is unknown how to decrypt the newer save files.
