    if you're able to modify HV code, why don't you modify your interrupts? this way you modify machine check (0x200?), illegal address translation (0x300?) and illegal instruction (0x400?) to output you the last accessed addresses. evade the problem of rebooting everytime :P

    Saw two intelligent posts here @Cameron and @uf6667. Awesome idea with the interrupts! Will try it today.

    A programmer of a great studio said some months ago in an interview.

    "i dont think that games piracy is a big problem, because poeple who burn those games does not belong to our main target group".

    i think its 50% truethness in that. if people burn games, then they are not 100% interested in the games, or they are to dumb to understand that games who are great needs to be supported.

    for myself i cant say that i allways played legal copys. but if i like a game, i buy it original. online mode, multiplayer or what ever. i want to play it with other people if i like it.

    best example. command & conquer. i own all titels (the first two times O.o) and i would never burn one of these games because the guys do a great job and deserve to be supported by my money.

    i can only say, i hope that the ps3 doesnt get a backup launcher, or sony implements a system that every game can only be locked on ONE account with a serial.

    If keys allow you to create essentially legit applications what would stop the hack from being software only? getting at them is the hard part but like the iPhone situation it could really be software only.

    If someone writes a CFW that the system thinks is legit and an updated version...
    Yeah, came to think about it after the guy answered mentioning the AES stuff... it's true cuz if it were like I said, then a specific FW update would be necessary for each console.

    My question now is: can the decryption key be used to encrypt data? I guess those are two different keys, right? I mean, the PS3 uses its own individual private key to encrypt stuff like, say, the HDD. And it uses a public key, common to every console, to decrypt data and perform checks.

    So, my question is, the key used by Sony and game devs to encrypt and sign data, like a FW update for instance, its not present in the console, is it? So how could you actually create legit applications?

    As for the Slim x OtherOS question, way I see it there are only two reasons why Sony could have removed OtherOS from the Slim line: 1) changes in hardware made it impossible for OtherOS to run; 2) OtherOS can be run on a Slim PS3 but was removed for security reasons. In both cases I guess Sony would've made it impossible to install OtherOS on a Slim PS3.

    Question

    Is it just me ? but I'm picking up that geohot is not 'excited' by this anymore ? Either that or he is curbing his enthusiasm as Sony are on to him. Either way, I hope he achieves his goals.

    AFAIK, things are a little bit complicated.
    First of all, there is some key, let us name it "Official content key". Sony has ENCRYPTION for using to encrypt their games, demos, content and so on. It is not stored inside PS3, only Sony has it.There is simply no point storing it inside PS3. PS3 decrypts this content with DECRYTPION key.

    There is "HDD encryption keys" which are different from the ones mentioned above and BOTH of them are inside PS3 (as PS3 decrypts and encrypts this type of content within the system)

    Correct me if I'm wrong.

    All that is needed is whatever the ps3 has. Using a different encryption would mean the ps3 with its decryption method could not use it.
