With this two things (and a few more) team twiizers could write a hack and sign the hacked save game data with the common-key >> the Twilight Hack was born. But the ps3 is secured against such buffer overflow attacks.If the buffers get be overflowed the console turns off and clears the ram (hope thats right). Hack is dead! Sure there are many ps3 exploits (such as tiff exploit) in the wild but all will be useless.
So every step on a dev is also a step for retail consoles.Other example: The retail ps3 get be hacked but in case the second encryption layer on disk is still uncracked how do you want to get a use able img? Or if no one knows how to make a pack file from a game to install it on hdd, how do you want to play games from it? It is not only to hack the retail ps3 or to find a hack and tell it every one, so that sony could patch it befor we know for what we could use it or better say WHEN! we could use it. It is also to HAVE something to use with it
And at last dont forget that we dont know any key for the ps3 so that we could sign the data and make it executeable like it works on the wii.
The Wii use .elf/.dol what the knowed from the gc.Im not sure but i think the elf/dol from wii will be a little bit different then the one from gc (but im not sure). This made it mor easyer to write a hb elf/dol. The ps3 use self´s, this will be a more secured elf, as idone explained it. Without cracking the self or finding a way to dump the elf out of the self they could not to study it. If some one could hack the retail ps3 what should we do without the ability to alter the data or to write our owen files?
So there for development on a dev ps3 are also importend like to keep infos such like the hdd encryption (exploit) be underground till we have a way to use it or some one could use it to make something good with it. Like to study, maybe new files, and get more infos about the console self.
Thx but my mentioning goes to that that the retail ps3 cant be hacked without hacking the development ps3 (to this time). If they could not understand how the console work how they should be able to hack it? So ps3 is a little bit different then the other two one. The wii would be hacked via a save game exploit and the common-key.
