Hey guys, I apologize if there's already a topic about this, but I haven't seen one in my time browsing here so I thought I'd make one. I was talking about how Mii data is stored with a friend, and I ended up looking it up on 3DBrew. They seem to have the entire mapping of the QR data figured out: http://3dbrew.org/wiki/Mii_Maker The main thing I'm interested in editing is the "copiable" value. Most of the QR codes I scan from random strangers are locked so I can't edit them at all - and while I appreciate that someone else made it, sometimes I think there's something that could be done better and I want to change it. Or, in the case of Tomodachi Life, I want to be able to rename the darn thing, which isn't an option if it's set to not copiable. So let's take a look at one I got from MiiCharacters.com. http://www.miicharacters.com/miis/qr_large/1972_peterg.jpg That's just a random Peter Griffin one I found. So I parse the data: http://zxing.org/w/decode?u=http://www.miicharacters.com/miis/qr_large/1972_peterg.jpg I end up getting this as the raw bytes. Code: 40 07 09 12 cf d2 5a 4c 0e 10 1c 44 cf 94 e1 67 e5 60 4e f5 12 b5 11 3e 3c 58 5f 48 b1 32 97 43 32 ab 4b 4e f3 15 6b 41 cd 08 e8 29 cd f0 c0 92 50 9d e2 3a 28 85 40 26 80 6c 20 ab 46 5d 6c 94 3b ee d1 bf 0b c5 1a ab 9a 5e 1b a3 73 02 01 ba f9 a3 7a 42 8d 59 30 ea d6 a2 12 d3 30 7b 4a ef 6b ee b3 cb 7b 92 f8 01 3a 47 82 9a 19 90 36 7b e8 f8 00 ec 11 ec 11 ec 11 ec Obviously this isn't very useful as-is, because most of that data is encrypted. However, 3DBrew says it can be decrypted using known text strings...? I notice the value at 0x9 is "10", not sure if the 1 represents "is copiable" or not, but I would assume that's just a coincidence since everything else is encrypted too. Essentially, if I could plug the raw data in somewhere and be able to decrypt and then re-encrypt it, that would be fantastic. I just want to play around with the Mii format a bit.
