Guys, i know you are waiting for the USB Dongle Master Key from me I have got now 2 fat PS3 with HV 3.15 but unfortunately no SX28 development board yet to exploit it

But i was not idle and the last and this week i was working on reversing of self decryption. And now i’m able to decrypt SELFs and SPRXs on my exploited GameOS by using HV calls only and no GameOS functions at all I reversed the interface to appldr which decrypts SELFs on GameOS 3.41.

So you wont’ get bored until i get the USB Dongle Master Key, i will make my findings and my source code public very soon and you will be able to decrypt your favourite games and programs by yourself Let the fun begin, guys

P.S. - I believe this one might deserve a news thread.

dose any one other then me really like what this guy is doing for the scene?

He is not decrypting self's from OtherOS, he is doing it using only HV calls from exploited 3.41

and it not working with 3.50 self's like GT5 since its crypted with new keys, which old appldr not contains.

Holy crap! This is awesome!

I can't wait to see what people do with this! Great job Graf!

*ps im fully aware that this is currently the big deal*

lol these news sites are quick to report any time he posts.

Hmm so if someone could find a way to load a homebrew app using the HV calls to decrypt a 3.50 game on the fly would that work? Basically take the source code when he releases it and incorporate it into some kind of homebrew app and decrypt the 3.50 update then find the keys to decrypt a game during runtime. I'm guessing the 3.50 update has the keys we need? So if we decrypt the update, bingo there's the keys and just incorporate them into the homebrew/source. IDK throwing around ideas. Not a programmer so I could be talking complete nonsense.

Anyways pretty sweet. Hopefully developers can make use of this! It sounds like it has huge potential.

hmmm i know this seems like a good news but im a complete noob and dont know what this means anyone care to tell me about the future possibilities?

PSX Scene should open a donation fund for stuff like this, we know our money is safe going to a 3rd party thats legitimate, if we had this and counters to see what the donations came to I'm sure it would make the devs complete their projects much quicker knowing a bonus will come should they meet their goal.

I.e. this for chokolo's SX28 board.
