Hacking RB2 Customs - Proof of Concept

[ccfman2004]

Too bad xorloser can't help us, I'm sure he would had figured it out by now.

It's pretty easy to load the rb2 elf into IDA and look at the code, I just haven't had the time to replicate the algorithm.

OTOH GHWT .bik files don't use any encryption at all.

If I get the time, I'll show you guys a video of this (even though I said I wasn't going to do Guitar Hero customs

)

Maybe I could make one... Just have to take a look at the midi files I guess...

I'm currently fretting Rosenrot by Rammstein (because it's really easy) so I might use it as a test song!

 

[ccfman2004]

Anyone have any luck decrypting the bik files?

 

[SFenton]

Not me, at a minimum.

 

[bozzer123]

any recent news guys. I'd really like to see this happen but cant contribute cause my computer is crap

 

[rikuumi]

looks kewl

Good job MrKinator

I have been looking at the ark files and seems to me that rb2 is able to play moggs as well as biks. In the songs.dtb file, all songs are marked with format equals 3, except the tutorials which are moggs. Also there is a tempsong.dtb file pointing to some dlc and with format equals 2.

I think that moggs could be injected in DCL. Unfortunatelly, I live in a PAL region and are not able to get even the free DLC, so I can not test. Could someone provide a data.bin with free DLC?

Thanks

I think the encryption key extraction process was changed for ALL formats (.bik and .mogg) in rockband 2. The xbox 360 still uses .mogg files but they have the same extra header as the .bik files in the wii version. Supposedly some people know how to decrypt them but I haven't been able to find that information anywhere.

Actually it's pretty easy to download stuff when you live in a PAL country

Here is what to do (thanks flies to tueidj for helping with this):

-First, make sure you don't have any important purchased stuff on your Wii (such as GHWT DLC which you won't be able to recover through a WAD)
-Also make sure you don't want to get DLC for any PAL game you own (as this stuff won't allow you to use the European shop)
-Now make a backup from your RB2 save (might not be needed but this is exactly what I've done)
-Erase your PAL account from the Wii Shop Channel (can't remember exactly how it's done but you might find it easily)
-Using Any Region Changer, set the Wii Shop Channel code to USA (which I think is 49)
-Connect to the Wii Shop Channel in order to create a new account (no need to tie it to a Nintendo VIP account)
-Boot RB2 and make a new save
-Get some free DLC!!!
-Erase your newly created save and get your old one back
-You can get free DLC on your PAL Wii and you haven't lost your previous save

(I'm thinking of puting together a clearer tutorial for this someday...)

That's likely happened, but the tutorials in the game are unencrypted moggs. I guess the game is able to handle old formats as well.

Thanks Heathcliff, I knew that, but I do no want to lose access to the European shop. Someday HMX will release RB2 in Europe, I hope...

Have you tried to reverse the steps in order to get access to the European store?

Thanks,
granberro

 

[ShakaHeath]

No I haven't tried this but I bet this will work... but will erase my US DLC...

is anyone still working on this? Ive just got a guitar for my wii and would love to be able to get customs working on the wii rb or ghwt

Yes we are

First Post Updated with new Video (small update on our progress)

Aww, no love for Knights of Cydonia?

How was this done?

Pretty much the same way Mrkinator explained in his new video, just with my own custom tools (though I'm assuming he used my bin packer).

He used an RB1 chart, I used a bunch of different tools (already available because GH3 customs are working) to extract the chart and song from my GH3 disc.

 

[Justin121994]

Do you guys have an irc channel.

 

[Mrkinator]

Sorry, when I get on a computer I'll put it up (iPod right now)

Yes, but it's hidden so the noobs won't come in asking for DLC
