Hacking vc games on usenet ?

[choupette]

I just saw this in usenet :

F-Zero.SNES-VC.NTSC.Wii-iND.rar

the nfo reads :

ND presents, 

F-Zero.SNES-VC.NTSC.Wii-iND

Size : 3 487 808 octets
Support : SD Card / Wii
Protection : Nothing

Needed:
Â- Nintendo Wii
Â- SD Memory Card
Â- Saved Channel *Included*

Instructions : Access your SD card and place the file named 'private' 
onto the drive. Take the card out of your system and
place it in the Wii. Navigate to your Wii memory management settings
and find the section that is labeled 'Channels'. You will find two tabs
inside, one for your Wii and the other for the SD card. Select the SD
tab and you will find the saved channel present. Copy it to your Wii
and you will be done. 


If you enjoy it, purchase it yourself. Wii did!

anyone can confirm this is not fake ?

Already posted and fake (at least what I thought).

 

[tjas]

This is a new one.. its easy to see if it's real but I don't have a wii..

 

[choupette]

neither do i =)

but anyway, I think I would have heard about it.

 

[DjoeN]

so far i know not fake but:

they're encrypted, so, nu use for it anyway

prolly will only work on the Wii it was downloaded with

Can't test it as the Wii only gets released 8 dec here :/

This works with the Wii 1.0. i.e. if you have given your Wii internet, it has gotten the update to fix this. Just like the Shop channel exploit that has been fixed by patches.

The 1.0 firmware does not have SD Card support...

I really have no doubts that its the real thing, but its unusable as it is.

Each ROM is encrypted in some manner and linked to your Wii, they are still trying to figure out how exactly. But actually ripping it is terribly easy since all you have to do is download and transfer to your SD card. The Wii itself says you can put games on your SD card if you run out of space on the built-in Wii memory (or avoid running out of it). It might have been possible with earlier firmwares, but its been patched.

I'm suppoing that each VC game actually contains 3 things :

-The game in ROM format.
-An encryption to lock it to your Wii. Possibly checking for a matching MAC address, friend code or something hidden/secret on your Wii.
-A 'pure' emulator with simple controller remapping functions, that translates your gamecube/VC remote controls to whatever the game needs it to be.

When the encryption is cracked, they will most probably find ways to get games on other Wiis, and probably even replace the ROM completly by another game that isn't normally on the VC by some simple hacking.

>>-An encryption to lock it to your Wii. Possibly checking for a matching MAC address,

Probably not that simplistic.. even the DS uses RSA signing/encryption after all...
The Wii are probably shipped with a unique public/private key pair, when you download a vc your wii sends its public key to the servers at nintendo and the vc is encrypted using it. That way only a wii with your private key can decrypt it and run it... all this is probably made even more complex by all the keys being signed/encrypted by a nintendo master key (CA/cert style) to stop people messing with their unit's keys, and hex editing the vcs to change the roms.

People seem to be under-thinking how software is protected ... heck arcade machines from the 80's/90's had encrypted processors, suicide devices,.. everyone is just going to have to wait, some 14 kid with a copy of visual basic isn't going to break the wii.

Are people capturing these datastreams from the Wii IP address ?

Are people capturing these datastreams from the Wii IP address ?

Nope, you can transfer the games from the internal memory to an SD Card then they just upload the contents of the file on the SD card

 

[Sick Wario]

i cant comment on vc games being transfered, but i have DL a bomberman 93 save file/folder structure, copy to SD>copy to wii memory and it works with my bomberman 93 channel/game...

 

[Shroomie]

Well, I got the files for this rls and decided to play around with the structure and files from this point before trying it.

it came in a nice little bin file, everything reads it as tracks.

a hex edit uncovered this:
Root-CA00000001-MS00000002-NG020c8d87

serial of it mabey?

let ya'll know if i find more

If you capture the datastream while downloading you can compare what is transfered vs what is written on the Wii ...
