Nintendo DS 3DSaveTool 0.1: Save Decrypter for Games

It's been confirmed by now that 3DS games save inside the cartridge just like DS/DSi games, and that the saves are encrypted. Fortunately the encryption scheme seems simple, as crediar has not only found out how it works, but created a tool that will attempt to both find the key used (which differs per game), and use it to decrypt or re-encrypt a save file.

This means that users with tools such as the NDS Backup Adapter+ can now fiddle with the save games of their 3DS systems, though restoring a modified save seems iffy at the moment.
