It can't be decrypted outside of 3DS (for now).Depends if the information is decryptable off the 3DS, haven't looked into this stuff in ages, but I'd assume it's something that can only be decrypted on the 3DS itself. Hopefully it's something that can be done one way or another though.
Since that info is stored inside of one of DLC NCCH, it would require original NCCH key from keyslot 0x2C.
Kinda, yeah.Like when you have to download the tmd to just get the title version ? xD
For DLC it downloads both tmd and control content to get icons and names for any new content.
