Video: PSP Game ISOs Running on PS3 4.41 OFW Demo Surfaces


Sponsored Links
91w ago - Following up on the previous updates, today [Register or Login to view links] shared a video demonstrating PSP game ISOs running on Sony PS3 Firmware 4.41 with details below.

To quote (via Wololo): You might remember the psp2ps3 tools, and all the excitement a few weeks ago around a recent hack breakthrough that allows people to run psp isos (and, potentially, homebrews) on a hacked PS3, by “camouflaging” the game inside a PSP Mini.

Although people believed this trick was reserved to PS3s running a Custom Firmware, this might become an incorrect statement very soon…

I was contacted by scene member CapetLeVrai who apparently found a way to run those PSP ISOs on a non hacked PS3 running the latest official firmware 4.41.

The current technique will probably not blow your mind for now, as it requires you to own both a hacked and a non hacked PS3, but it could open huge opportunities in the near future if the right people decide to look into that. The basic idea is that after being installed on a CFW PS3, the ISO can be transferred to the OFW PS3 through the integrated Data Transfer Utility, and will still run perfectly fine.

How It Works

The PS3 allows you to copy data from one PS3 to another, usually when you want to transfer all your existing content in the case you bought a new PS3. This is done by connecting your two PS3s with an ethernet cable. What CapetLeVrai did, which sounds simple enough but appears to work, was to install the game on his hacked PS3, then copy the entire content of his hacked PS3 to the OFW one with the Data Transfer Utility, and the hacked iso then simply accepted to run on the OFW PS3.

Please note I haven’t confirmed myself because I’m beyond lazy and don’t want to lose my OFW PS3′s content (copying from your hacked PS3 to your unhacked PS3 will erase the previous content!) but from what I can tell this is legit.

Now, why would it be interesting if this requires a hacked PS3 in the first place? Well, it shows that once installed, the game seems to be able to bypass the standard DRM security checks on OFW that should prevent it from running in the first place. Or, rather, that the hack perfectly tricked the OFW PS3 into believing the game was legally acquired. Which means that if people had a way to run a package installer on official firmware PS3s, there could be a way to install and run psp isos (and, who knows, PSP homebrews) on the latest PS3 Official firmware.

Is it far fetched? Probably. But exciting? Definitely. Enjoy the video, in French. If you are able to confirm this and post a video on your own, please do credit CapetLeVrai for this discovery, as, as far as I know, nobody else had found that (at least publicly) before him.





From the video's caption: This vulnerability requires a PS3 CFW at least able to install the file. Pkg

I am not a hacker, at least I do not code and I do not claim to be a pirate, I am interested in this field and I put it gradually but I'm still far from finding and exploiting real flaws, this video aims to acquaint developers much more qualified than I am to try to find a solution for users who want to enjoy their PSP games on PS3 OFW (Official FirmWare) or via a possible HEN CFW (as I know KaKaRoToKs found a flaw like this...

For console users DEX (formal or via CFW whatever) who want to transfer data on a console OFW:

System mode: Normal
XMB Operation Mode: CEX
Debug Menu Type: CEX QA
LV2 Kernel: CEX
Target Type: CEX

This thank you very much for watching the video, if you are interested in PlayStation hack let me know in the comments I will make a small series of video to tell you all this technical vocabulary that ultimately is not that complicated!

Finally, from samson: Also i found the kurok source files (bladebattles.com/kurok/files/), harryoke you was asking for sources Wavegen pspsdk sample:

No screen output (because its suffers the same problem as gta games) but audio and controller work, X to change wave form, push joystick up for higher frequency and down for lower frequency. do not have volume too high before starting, enjoy.

Update: From xxmcvapourxx: KIRK 13 ECDSA

Guys, After months of researching and alot of studying on security this might help other devs.

Let me explain: LV2_kernal.elf hold's the public key underneath holds the ECDSA curve.

This has been updated in wiki euss had kindly confirmed and helped me. This does not lead getting private keys but its usefully for other devs.

From zecoxao: Some keys stuff (kirk/psp related)

Download: [Register or Login to view links]

That is a decrypted self found inside emulator_drm.sprx in pspemu. You can look at the keys starting at offset 0x19EA0 from there until 0x19F80 you have kirk cmd 4/7 keys (already documented in libkirk) On offset 0x1A060 you have the section 0x6 keyseed and below it, some ecdsa stuff (the seed is already documented in seeds page, the ecdsa stuff however, isn't) This is for filling up the keys page. it's also good to have a look at.

PS: You can only find the seed on later firmwares. 3.55 and below firmwares do not have that seed.

PSP2PS3 v.1.7.3 is online

CHANGELOG:

v1.7.3
-MAKE_EDATS_CEX:
---FIXED: Starting EDAT Tool when user chooses to unpack iso
-MAKE_PACKAGE:
---FIXED: Issue when function sleep doesn't exist in system - pause will be used insted of it.
-ISO2EBOOT:
---Extension in output filename is now required
---DONOR.PBP isn't required anymore. Replaced fake_np with one which doesn't need DONOR //thanks to Aldo (aka aldostools)

From PatrickBatman also comes a brief guide (easy way to rename iso/cso to np.iso or np.cso), as follows:

1. Obtain PSP game in PKG format and put it in this directory. (Only for DEX users - you need also make_edata_npdrm.exe - put in tools dir)

IF YOU WANT TO USE ISO INSTEAD OF EBOOT.PBP

  • Copy ISO file here
  • RUN ISO2EBOOT (name output PBP as EBOOT.PBP)
  • GO TO STEP 3

IF ERROR APPEARS THAT ISO IS TOO BIG TOO FAKE THEN TRY TO DELETE FROM ISO UPDATE DIRECTORY IN PSP_GAME/SYSDIR USING UMDGEN. IF ERROR APPEARS THAT EBOOT ISN'T SIGNED THEN UNPACK ISO WITH UMDGEN, DELETE FILE OPNSSMP.BIN FROM ISODIR/PSP_GAME/SYSDIR/ (THIS FILE COULD NOT EXIST SOMETIMES). COPY EBOOT.BIN TO PSP2PS3 DIR AND RUN SIGN_EBOOT. REPACK ISO USING UMDGEN WITH SIGNED EBOOT.BIN (OVERWRITE OLD ONE) WORKS ONLY IF GAME HAVE SIGNED MODULES (SIGNEM MODULES STARTS WITH "~SCE")

2. Put pkg in PSP2PS3 dir and run EXTRACT_PKG

3. Run MAKE_EDATS_[CEX/DEX]

4. Run MAKE_PACKAGE (after packaged is created script will ask to tranfer pkg to PS3 via FTP)

(IMPORTANT FOR DEX USERS! If you have "Package Manager" [eg in Rebug FW] and you want to install package you'll see only "Please Wait" message. Wait till message dissappear then go to Package Manager -> Playstation Network Content and install your package from there).

Tested on Rebug 4.30.2 CEX/DEX.

JOHNBOI ... the process is not that complicated ... and szczuru's PSP2PS3 is getting simpler and simpler ...

TBH ... the "just two clicks GUI" that does everything comes always after some people get far enough...

Also LocoRoco 2 is slightly bigger at 1.68GB if you want to integrate it.. haven't seen any 1.7 or 1.8's yet though.

Does the PRX encrypter sign unsigned PRXs and make games work that otherwise wouldn't? Cause I might go back and retry the games I've tried if it works.

Input name of directory with EBOOT.PBP and EDATs in it.

BTW Gran Turismo won't work - isn't compatible.
