|
 |
There are reports of a Zelda Gamesave exploit, over at tehskeen. As it is right now, the process to build a hacked gamesave is a bit complicated, but you shouldn’t need to build one on your own. Hopefully, this will lead to a homebrew loader soon.
Yes, that’s right - an exploit for the Nintendo Wii has been discovered and it allows you to run custom code. The method is pretty simple. Copy over a save file for Zelda, load it and the code runs. Don’t get too excited yet. They have only been able to run 4 lines of code, but this is in a days work.
Segher was the one to find the exploit and Bushing has been testing it out with the aid of the USB Gecko. The process is far from simple as once you modify a save game it requires it be to signed with 3 keys. Here’s some info from Bushing.
Once the Wii decrypts the save game, it checks its signature. Every Wii has its own private key which is used to sign save games, and when you save a game, the Wii actually saves three bits of data:
* The encrypted save game
* The signature for the save game (using your console’s private key)
* A copy of your console’s public key, signed by Nintendo.
Of course, the end user wouldn’t have to go through this process unless they were wanting to inject their own code into the save game, but that shouldn’t be necessary because when I asked Bushing what his goal was he answered:
Assuming we don’t run into a wall, it should be able to lead to a homebrew loader. I hope. No promises.

worth noting that those pictures are from the gamecube version. if a hax is found, it would still apply to Wii though, apparently.
