Since rawksd is probably never going to support RB3 customs, I started to research on my own the RB3 DLC format.
I've ran into a speedbump however, while I was able to replace existing DLC songs with custom data, I was unable to add new songs. This is a problem because it would mean you wouldn't be able to use official rock band DLC and customs/imports. I tried to ask others who knew more about the Wii RB format how they managed to do this with RB2, but I didn't get too far with that
Here are some tools, examples, and most of the info on RB3 customs that i was able to get. I decided to release this in case someone found out how to add new dlc instead of replacing old DLC, if you do, please pm me, it's pretty much the last step towards full customs on RB3
(this is the first program I've ever made, it will be buggy)_
Tools: http://www.megaupload.com/?d=S05S95ID
This is a short description of the programs, please read the readme.
rbcrypts.exe: This is a program i made that will encrypt/decrypt RB3 .bin files (located on your sd in the SZJE folder). The encryption has changed from RB2, instead of all the DLC using one encryption key, it now uses keys specific to each wii to encrypt. (this is probably why you haven't seen any RB3 DLC .bin files at your local warez site because the files are encrypted to your wii only). To get your key, use rbkeys.exe tool below.
rbkeys.exe: This is another tool i made that will get you the necessary keys you need to encrypt/decrypt sucessfully. It requires that you run bootmii and dump your nand. This will dump a keys.bin file. Load this keys.bin file from bootmii into where it says xyzzy (its a error by me). You will also need to download a official RB3 DLC file from the music store. Browse for both of these files to generate a rbkeys.bin file. This file can be loaded into rbcrypts.exe above for proper decryption/encryption.
Info on RB3 DLC .bin format:
Header:
0x0 to 0x7F (length 0x80): also known as a Bk header. This header is the same for every DLC file, with the only thing that changes are:
console ID at 0x8 (length 0x4)
size of TMD at 0x16 (length 0x2)
size of encrypted content at 0x18(length 0x4)
size of file at 0x1C (length 0x4)
TMD:
0x80 to size of file - size of encrypted content : A stripped TMD without the certificates at the end of the file. TMD parsing info can be found at (http://wiibrew.org/wiki/Title_metadata)
Content:
size of file - size of encrypted content to End of the File: The contents of the .bin file (encrypted)
All of this info is most likely only useful to people who know the rb format
Maybe someday RB3 customs can happen...
