Hacking VC titles specific to your Wii

[xthedakmanx]

Hello all. I have a question that's been bothering me for a while.


Say you have a VC title installed on a hacked Wii (Which I do), and put onto the sd card. When you take the SD card out, put it in another Wii, and try to run it, It'll say something like "can not run on this Wii".

Now...With all the wad managers and everything, is it possible to change the uh...idk what it's called..."Which wii this VC game is installed on" code, so that you can reinstall it on the hacked Wii to the SD card, move it to another Wii, then actually be able to play it on there?

I haven't messed with this in a while, but I imagine most any wad manager will let you extract a game channel wad from your console.

Blue Dump is what I use to extract wads: http://gbatemp.net/threads/bluedump-alpha-2.191486/
I cant remember if you need to know the title ID, or if it tells you the title, but if you need it, check the database: http://wiibrew.org/wiki/Title_database

Side note/question: Why do people bother with VC? There are emulators that accomplish the same thing and more.

No, I mean like....can you edit a VC game for Wii#1 (hacked) which is installed onto a sd card, and make it work for Wii#2 (not hacked)?
Like, editing which Wii it was bought for?

one way or another, its already pretty illegal... so why not just get the respective wad from wherever and install that on the second wii?

Here is a quote from wiibrew about the data section of the games:

The data is encrypted and little can be said about its plaintext. At the end of the data two certificates are described, each one referring to the unique Wii ID thus making it plausible that the data is encrypted with a secret key only known to ones own Wii. A checksum of some sort might be the last piece of information stored in the penultimate block which is then followed by a last 64 byte block of zeros.

So to get it to work on another wii, you would first have to find you own Wii's unique key (not sure if there is a way to do this), decrypt everything, then get your friends unique key and re-encrypt the data. If the last portion is a checksum, then you would also have to change that to match the new data.

Even if there is a way to get the unique key, it would most certainly require that the wii be hacked, and if the wii is already hacked, then you might as well just use wads or an emulator homebrew.

Also the wii will only load tiles from the sd card when the ticket for that title is already installed on the wii. So if the title was not installed on the 2nd wii it would not load it from the sd card. It install it via wad, if you wan't an sd option to take to a friends wii and not install on it, use nand emulation.
