    First PSP Signed Homebrew is Now Released

    First psp "signed" homebrew..

    P.S. None of those keys are on the ps3, don't bother looking there. More keys: http://pastie.org/1467912

    For those who wonder, spock cmd 0x09 key is used to decrypt UMD keys stored in idstorage, those keys are then used by spock cmd 0x08 to decrypt the UMD master key (per disc key) Then this key is used in spock cmd 0x0A to decrypt the UMD raw sectors. Each different psp regions seems to have its own sets of UMD keys.

    You can more or less access Spock through lepton's ram (there is some hidden test mode on lepton allowing you to do just this). More on this later If I ever get the time to clean up those sources.

    P.S. Let's hope sony uses kirk cmd 0x12 for the kernel prx ECDSA checks and that they did the same fail as on ps3, would someone be so kind as to check it out ?

    Syntax for kirk cmd 0x11 key:

    +Rep for the news ModderFokker, and ya, if it was perhaps a new/signed PSP iSO Loader I'd mainpage it but for now I am moving this to the PSP Forum for discussion.

    We just don't have a big PSP following here, and even in general the PSP scene seems to have died down in recent years as more people moved to PS3 perhaps.

    Oh this is very nice progress as concept turns into reality we will see psp/ps3 turned on its head as retail non jb units accept signed homebrew left and right.

    Good Times. After all, It only does everything.

    Good news. I hope some one will come out with a real CFW soon or find a way to get those v3 boards working properly, by properly I mean not through HEN.
