Basically if they have found a way to make the game crash then there is a good chance that they have a way to inject code into the game. Getting the game to crash is doing something that it was unintended to do so and so is injecting code.
I'm not going to claim this particular exploit is real or not until I see harder evidence but I do know a bit about buffer overflows and getting something to crash means they are getting their. |

I believe that inserting valid code to jump execution to a homebrew app is what we'd need to insert into the saved game, yes?

What you said is exactly what they did.

It's probably a buffer overflow.

Hmm, answering my previous post, I think there is a homebrew ISO bootloader for wii, I could be wrong.
Anyhow, When I get my new PC, (Old one broke, I'm using my Wii to post. XD) I think I'm gonna see if I can code an app to use a wii-mote to control a wii-esque media center. Do you guys think this is a good idea? Would you download/use such an app? |

*Removed section concerning hacking Mario Galaxy*
Question: In Zelda, and in Mario, the name of the savegames are displayed before they are loaded, so you can pick which one you want. How does the game not crash until you load that particular savegame, when the name string is hacked, as in this Zelda exploit?

Is it possible to add a homebrew channel from the SD card,(Not with running the savegame for this channel)
and use that instead of the installer which is the new savegame?
Or did Team Twiizers do it with the savegame because they had to do it that way, or because out of preference?

Well right now the channel isnt even released but I would suggest just renting a copy of zelda and running the installer when it is released Wii games rent for about $5 to $7 depending on where you go.
Anyways I was just wondering if anyone is going to release a dvd player homebrew cus i want one  isnt there one already that they can just mod the code a bit for us to run with the exploit? |
