Video: OpenCobra Cobra USB Dongle PS3 Payload by Oct0xor Demo


Sponsored Links
102w ago - Following up on the PS3UserCheat and True Blue unnecessary DRM-infected dongles being hacked alongside zadow28's work, today PlayStation 3 developer oct0xor shared a video of his OpenCobra Payload which aims to render the current Cobra USB dongle from Max Louarn useless.

Below are the details from his [Register or Login to view links], as follows: "First I am going to say that this is not going to be an article, just a first blog post and some info about my recent project.

Finally I got my hands on cobra it was quite a lot of time since I touched this last time. There was s good things happened since then eg. I reverse engineered usercheat and true blue, had done a lot ps3 and not ps3 related hacking. There was a bad things eg. BlueDiskCFW, lv0 leak, a lot of devs leave the scene...

Cobra was for me really "the last" thing I have to do.

The last time when I worked on this I didnt had a dongle, and all what I had was a dump by JaiCraB. I reverse engineered it as much as possible, figure out almost all tricks, encrypton and etc. And figuare out that it reads a lot of data from dongle, and I cant do much without dongle itself. Thats why I put this project to the back burner.

Well... I had never buyed anyone dongle, and I never was not going to. All my dongles was donated (thanks again ) but not that time.

it was hard for me to make this decision but a few days ago cobra finally shipped to me...

3 days and now its all over.

Security is good enough, but not without big security risks. But it still the best crypto/obfuscation what I had seen on ps3. Sony have something to learn from this guys, especially now.

Cobra / True Blue almost identical, have the same source code, if you ever hacked 1 thing, 2nd wouldnt be a problem. The main functionality, honestly, not changed since original jb. Thats a shame. Thats why I cracking them like nuts





On the fourth day I taked a decision to make my own "OpenCobra" payload. only clean code without drm and garbage, to be able to port it to any new firmware, and change/add features. It taked 2 days, 3000 lines of asm, and you had seen the result.

Atm it based on 4.1 payload, plans for future is check/add new features from 4.4/5.0. Port to a new firmware (if cobra will not do this for me), and realize all nice innovations from new version of psp emu, such as better emu accuracy, 3D and etc...

In video you had seen Payload Loader. Thats the all code it has:

This tag related patches handled by mngr. So far I want to move it in payload. First I have to check how it handled in 4.4 / 5.0

Not sure yet when it will be released, if it will be, but we will see.

Keys!

If this subject will be interested for people, maybe I will write a full article about True Blue / Cobra analysis and hacking.

btw: Me and ~ some psp mysterious dark figure ~ reverse engineered algo for generating valid psp isos back to jule. But saves and a lot of games dont work without patching. So cobra's patched emu much better there imho."

Below are some additional pics from his blog which simply states: Usercheat + Cobra = <3

From flat_z: Here is some explanations to make things more clearer. If you read my twit about ps2_netemu you can see that I reverse-engineered it. It includes almost all things which are required to make custom disc images of original PS2 discs and run them on the PS3 if everything will works fine. So it can lead us to the process of remastering PS2 discs which includes making of ISO.BIN.ENC (the encrypted version of original image which can be read by the PS3), creation and encryption of .VME files (virtual memory cards), ISO.BIN.EDAT (includes the title ID of disc).

The only thing which is not currently known is the format of decrypted CONFIG file (I can decrypt the file and encrypt it back but it have a complex format). It is optional and can be empty but I'm afraid that some games requires it to run on the PS3. My plan was the creation of PS2 remastering tool and I wanted to share it. Although I even not sure will it work or no but there are many chances that it will.

But something happened before I started to do it. My HDD on the laptop died and I have all information regarding PS3 on it. Although I was able to restore some important files but not all. So I need a time to buy components for a new computer and build it. For the same reason, I have a delay on my real job (I'm working as a free-lancer) so I will going to do my job before I start to do something new for PS3.

P.S. I see many questions about compatibility. You don't need a backward compatible PS3 console to run PS2 games through ps2_netemu because it is software emulator and doesn't require any PS2 hardware components. Also I think that ps2_netemu is more better and stable than ps2_softemu but this statement requires testing.

Finally, from naehrwert (via twitter.com/naehrwert) comes some related Cobra ODE EID0 information (ECDSA from pastie.org/6169158) , as follows:

While this is definitely interesting news, odds are it's just a ploy for the Cobra Team to release a new dongle that will be 'required' for their upcoming PS3 4.3x CFW unfortunately or the PS3 ODE in order to further line their pockets with PlayStation 3 sceners' hard-earned cash once again... as always, time will tell for sure.

Which RAP did you use to encrypt the iso? Make sure you use 2P0001-PS2U10000_00-0000111122223333 and try again. Use a hex editor on it and look for this in the first 16 bytes- if you see instead something like JP0102-NPJD00015_00-0000000000000000 then you used the wrong one.

Hi, if someone can slap me about the head and tell me where I'm going wrong I would be grateful. I have placeholder installed and latest MM but when I select a PS2 game and then try to load using placeholder I just keep getting "The copyright protection information is invalid (80029513)".

Driving me up the wall...

Hmm, I tried the Multiman method, installed both the PS2 Classics Placeholder package (17MB, shows PS2 placeholder app on XMB and installs game\PSU10000 folder) and the PS2 Classics Placeholder R2 package (153kb). Then I created a folder for one of my working rips (PS2ISO\[SLUS-20069] The Bouncer), and ftped the ISO.BIN.ENC over to here.

The Bouncer shows up in Multiman, downloads the cover, but when I run it it just goes to XMB. I ftped it to the PS2 Placeholder XMB's folder (game\PSU10000), and it runs fine from XMB. Why not Multiman? Anyone else get this to work? It would be so convenient to load up my rips and play them alongside everything else.

Okay, I've figured it out. The one rip I can't get to work is FF12 International Zodiac Job, because it's already patched with the fan translation pack which must alter something.

Anyway, you only need the PS2 Classics Placeholder R2 package (153kb) and mM 4.30.

1. Install PS2 CPR2 package and update mM to 430.
2. Whichever method you prefer (via ftp client or mM file manager), on the PS3 create subfolders for each PS2 ISO. Name them [gameid] gamename, ie. PS2ISO\[SLUS-20069] The Bouncer.
3. Using PS2ClassicsGUI (I used 1.4), place your 2P0001-PS2U10000_00-0000111122223333.rap (or whicever RAP you use to encrypt ISO) file into ..tools\scetool\raps.
4. In PS2ClassicsGUI, hit the Encrypt tab, open your iso rip with the black folder icon, and copy/paste or type the name of the RAP into the Content ID field (ie. 2P0001-PS2U10000_00-0000111122223333). The Klicensee field should automatically populate with the hex code pulled from the RAP you copied in the aforementioned raps folder. In this example, for the generic PS2 placeholder example, the klicensee code is E4E54FD67C16C316F47829A30484D843.
5. Click the Add LIMG Sector button (if available), say yes, then the bottom Encrypt button, say yes.
6. The newly generated ISO.BIN.ENC will be in the ..tools\ folder. Take that and copy/FTP it over to your PS3 into the PS2ISO folder you created (example PS2ISO\[SLUS-20069] The Bouncer\ISO.BIN.ENC).
7. In mM, under the Retro column, hit Refresh. If you named your folder's game id correctly, mM will pull the cover automatically. The title will be exactly waht you named the folder, minus the game id part.
8. Hit x to run the game. mM will exit to XMB. (This is the part that confused me initially until I recognized the behavior)
9. Go to the PS2 Classics Placeholder icon, and hit x to start. Your game should load after a bit and a couple of resolution changes.
10. Play! No package creation required.

So basically, it's as easy as create your ISO.BIN.ENC and the corresponding game folder on the PS3, then copy the file over appropriately and enjoy. Hope this helps anyone else having issues. mM will pull the artwork and create the SAVEDATA files for you. Big thanks to CaptainCPS-X and of course DeanK for mM, and no thanks to Sony for removing PS2 emulation!

Playing Final Fantasy X International (JP) for the first time as I type this. Thanks again guys!
