First 4 bytes IS a Mii ID, you can check gold-bottomed MIIs.
- I see Gold-bottomed Miis have a header of 0x11 instead of 0x91 but what's a MiiID? Where did you hear of that concept? (btw use the signature button) --Elisherer 21:39, 7 February 2012 (CET)
I get the suspicion that the block from 0x18 to 0x5C is in the same format as Wiimote Mii data, however it seems to be little-endian in the case of the 3DS. This may or may not help figuring out the encryption. Also, the 0x14 bytes at 0x5C may be a SHA1 hash of the Mii data, and the 0x10 bytes at 0x10 may be used as an IV for AES-CTR encryption or something... --Luigi2us 23:17, 7 February 2012 (CET)
