3DSaveTool v0.1 by Crediar / BroadOn Crediar has released a tool that can be used to find the XOR key used for encryption and use it to encrypt/decrypt EEPROM savefiles of 3DS games. So how is this useful? For the moment, very little, but this is a first step in the right direction for 3DS hacking. Who knows? it could be sooner than you think before people are able to dump 3DS cards! Anyway, here's a little bit of info about 3DS Saves posted on the 3DBrew wiki.
