seems to me a big fake as usually ...

superrob · Feb 26, 2008

I will test this tool out in a few hours!

Anakir · Feb 26, 2008

Wait what? What does that mean..? Does that mean we don't need a modchip and just this application to play back up games?

gEist · Feb 26, 2008

can't be fake... this "group" made also the first version of rawDump!

No. After modifing a Wii Iso the "Sign" Nintendo put on the games will be invalid.
Then after modifing you need to make a new "sign" to the game to make it run again.

So.. with this.. we could have homebrew on DVDs?

Seems too good to be true..

calm down dudes, if it's not a fake, we may be able to bypass the firmware updates

But this could lead into someone manages to make changes in a games update to make custom firmware! That runs backups!

They say VC games and channels can be signed too. It is in the TO-DO list contained in the readme.

That part would be extra cool

Imagine Homebrew channels

CockroachMan · Feb 26, 2008

Every day we see something new on the Wii hacking field! That's great..

superrob · Feb 26, 2008

Great for us.
Bad for Nintendo

Right, so would a tool like this make wii scrubber obsolete? I dont know enough about the wii disk stucture to know. For example, would we be able to extract the data files from a wii game, ignore the garbage, and re-encrypt the datafiles/structure to rebuild a smaller iso?

I imagine this tool could be used for modchip users to load homebrew from a disk, but he also mentions that channels could be created with it.

Perhaps someone could clarify, as the english on the linked page is a little hard to follow.

This tool just makes a new "sign" for the game that says its valid.
But i would say Wiiscrubber still great but yes maybe it would be better to remove the data permanently from the disc.
That would allow us to "shrink" the isos making them smaller.

It looks like you cant decrypt scrubbed isos!

VascoAlmeida · Feb 26, 2008

I dont think anyone is actually seeing what we can do with this..

I can be wrong, but think guys.. What if we take all the firmware and region files of the Iso and put the ones from a USA game that works on all regions ? Suposedly since it will Re Encrypt and Sign it.. It should work on the Wii, and as the files have been changed the game will work on Pal or Usa, even if its a Japanese game that shouldnt work right ?

Maybe its a bit confused but shouldnt i be right ?
