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


Sponsored Links
100w ago - Following up on the previous updates, today CapetLeVrai 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:

Download: [PSP2PS3] WAVEGEN [Remaster].pkg

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.

KIRK 13 ECDSA point multiplication

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: https://dl.dropboxusercontent.com/u/35197530/psp_iso_spu.elf

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.

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

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

I have ReactPSN and I try this method now...

So when I start 3. MAKE_PACKAGE.bat ask me "Input game/Placeholder directory name [or hit enter PSPPP0000 will be used]" - so do I pres enter, and use PSPPP0000 or UCUS98632 which don't have a MINIS.EDAT in USRDIR?

Just wait man

I download PSP2PS3-FinalFantasy-CrisisCore.pkg and works perfect on Rogero 4.40 v1.03


Strange...
Do you have ReactPSN? You can try something...

Copy "rk" file from tools directory to somewhere else and rename it from "rk" to "something.rap" (yes, with rap extension). Then install it on PS3 using ReactPSN.

Try to use "change gameID" when using MAKE_PACKAGE.

On which CFW are you on?

Do I need .rap for this PSP2PS3 v1.7.2?

Because I create .pkg and my PS3 need to go PlayStation Store.

Just use PSP2PS3

PSP2PS3 v1.7.2 IS NOW ONLINE

Changelog v1.7.2:

- Couple bugfixes
- Added check for exist load_tmp/save_tmp/open_tmp directories in placeholder
- Replaced old EBOOT.BIN signing tool with new one (BIG THX to RikuKH3)

ISO2EBOOT

IF YOU WANT TO USE ISO INSTED OF EBOOT.PBP

- Make sure that you have EBOOT.PBP in PSP2PS3 directory that could be used as DONOR (EBOOT MUST BE BIGGER THAN ISO)
- Copy ISO file here
- Rename EBOOT.PBP (DONOR) to DONOR.PBP
- RUN ISO2EBOOT (name output PBP as EBOOT.PBP)
- GO TO STEP 3

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") CHECK IT OUT:




There isn't bigger than 1.8GB 'caus 1.8GB is max capacity of UMD.

Sorry I'm stupid here does any PKG bigger than my ISO work ? Dosn't matter which Pkg ?

2. Obtain PSP game in PKG format (eg from PSN links) - PKG MUST be begger than ISO.

Does anyone have fond a PSP game in PKG format bigger than 1,8 GB ?

PS: merge
