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


Sponsored Links
66w 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.


GIT: github.com/uofw/upspd/wiki/KIRK-13---ECDSA-point-multiplication

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: [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.

Hiyas, do I still need a dongle to play these? I got a few installed, some black screen, some work fine. My real issue is nothing will let me save... I looked through this post and a few others, is there a step I'm missing to create a "psp" memory card on the ps3?

To quote, roughly translated: BiteYourConsole releases to the public a new update of Bite, this is the version 1.3 which contains many good news.

The program allows you to play your backups on ps3 psp. This new update using the program PSP2PS3 arrived at version 1.7.3a, below you will find the changelog and the various features of the program.

Changelog:

  • MOD Aldo alias aldostools
  • Simplified the procedure to process the PKG with a simple click
  • Automated procedure
  • Added theme music
  • New GUI (Form of PSP)
  • Added "select" button to create a PKG file for console DEX.
  • Adding a video guide directly from the application, viewable by clicking on the circle
  • Adding English version
  • Increased compatibility for games

Features:

  • Possibility to convert our backup PSP for PS3
  • Possibility of extracting the files PKG
  • Possibility of converting a file format ISO CSO
  • Possibility to create a PKG file from an ISO file
  • Ability to create a PKG file (Console DEX)
  • Ability to raise or lower the music volume with the + and - just like on the PSP
  • The ability to create pkg file for games over 700 mb

Guide:

Enter a file format CSO, ISO or PBP renaming it 'NP' in the program window, click the X button in the PSP, you can see a video guide by clicking on the rim.

From this screen, we can extract the files from a PKG convert a CSO to an ISO file or create a PKG placed directly from an ISO file, also clicking button we can select the steps console DEX.

In the program we have also added a musical theme, you can edit the buttons indicated by the arrows.

Video Tutorial:





Finally, from aldostools: I uploaded a new "mod" of PSP2PS3 1.7.3d. The problem with the save is caused by the load_tmp/open_tmp/save_tmp folders. They fix some games like LocoRoco Midnight Carnival, but also can affect the save of other games like Dissidia: Final Fantasy.

So, the script now asks if you want to add or not the load_tmp/open_tmp/save_tmp (if you press ENTER when prompted, the default is NO)

Bruteforce Edat 1.0.3

It's a dev klicensee bruteforcer that can be used to find the klicensee used on edat files. It uses BuC's dev klicensee validator to test the potential keys. The tool works in a similar way as Scetool/Bruteforce tool used to find regular Klicensees.

Changes in v1.7.3d mod by aldostools:

  • Fix: Added option to include or not the load_tmp/open_tmp/save_tmp in the placeholder (The load_tmp/open_tmp/save_tmp fixes some games like LocoRoco Midnight Carnival, but also affect the save of other games like Dissidia: Final Fantasy)
  • Added support for context menu: run "Right_click_context_menu - CSO & PBP.bat" as administrator
  • The PKG now uses the original name of the CSO
  • ISO2PBP.bat now uses the old version of fake_np 1.0 if the ISO image is smaller than 133.4MB (this helps to speed up the conversion & makes the PKG smaller)
  • Disabled the question about upload the PKG to FTP (it can be enabled commenting the goto ftp_no in 3. MAKE_PACKAGE.bat)
  • Improved the speed of MakeEDATs.exe (now should work better)
  • More bug fixes

Changes in v1.7.3e mod by aldostools:

  • Fix: Added option to include or not the load_tmp/open_tmp/save_tmp in the placeholder (The load_tmp/open_tmp/save_tmp fixes some games like LocoRoco Midnight Carnival, but also affect the save of other games like Dissidia: Final Fantasy)
  • Added support for context menu: run "Right_click_context_menu - CSO & PBP.bat" as administrator
  • The PKG now uses the original name of the CSO
  • ISO2PBP.bat now uses the old version of fake_np 1.0 if the ISO image is smaller than 133.4MB (this helps to speed up the conversion & makes the PKG smaller)
  • Disabled the question about upload the PKG to FTP (it can be enabled commenting the goto ftp_no in 3. MAKE_PACKAGE.bat)
  • Improved the speed of MakeEDATs.exe (now should work better)
  • More bug fixes

Changes in v1.7.4 mod by aldostools:

  • Added resign method suggested by Celebratesparta. Thanks to Romangelo for the more clear tutorial (posted below).
  • CSO2ISO now calls SIGN_EBOOT.bat instead of 1b. ISO2EBOOT.bat
  • SIGN_EBOOT.bat now extract EBOOT.BIN from NP.ISO, decrypt EBOOT.BIN, resigns EBOOT.BIN and add EBOOT.BIN, BOOT.BIN and blank OPNSSMP.BIN back to ISO
  • Added: WQSG_UMD_R31.exe, eboot_decrypt.exe to tools folder
  • Removed save_tmp/open_tmp/load_tmp from root folder of template
  • Extended wait time on MakeEDATs.exe

With the new process I could even resign games patched with Prometheus.

Some games that previously didn't work for me, that now work are:

  • Vanguard 1
  • Hot Shots Shorties Blue Pack / Green Pack

I haven't tested more... but it seems the compatibility is really improved. Brief Guide:

1. Download and extract PSP2PS3_v1.7.4_CEX-DEX
2. Run Right_click_context_menu - CSO, PBP & PKG.bat (with administrator privileges)
3. Right click on a CSO and select "Convert CSO to PSP2PS3", answer some y/n questions and wait until the program finish.

If you have an ISO, put it in the PSP2PS3 folder, rename it as NP.ISO, run 1b. ISO2EBOOT.bat, answer some y/n questions and wait until the program finish (if you want to resign the EBOOT.BIN in the ISO, rename the ISO to NP.ISO and run SIGN_EBOOT.bat).

If you have a PKG for PSP downloaded from PSN, right click on the pkg, select "Convert PKG to PSP2PS3", answer some y/n questions and wait until the program finish. If you have the EBOOT.PBP already extracted and signed, put it in the folder, run "2. MAKE_EDATS_CEX.bat", answer some y/n questions and wait until the program finish.

PSP Emulator Tutorial by Romangelo

1. extract EBOOT.BIN from the game ISO
2. use eboot_decrypt.exe to make BOOT.BIN from EBOOT.BIN
3. rename BOOT.BIN to EBOOT.BIN
4. use SIGN_EBOOT.bat to sign EBOOT.BIN
5. put it back to the game ISO
6. convert the game to PS Mini

Update: Here's my tutorial for people who still can't do it (using FF3 for the example):

1. extract EBOOT.BIN from FF3 ISO, using WQSG_UMD
2. put EBOOT.BIN in the same folder as eboot_decrypt.exe (from DNRiper) then run eboot_decrypt.exe, you'll get a BOOT.BIN file.
3. delete EBOOT.BIN (to avoid confusion)
4. rename BOOT.BIN to EBOOT.BIN
5. run SIGN_EBOOT.bat (from PSP2PS3 1.7.3a), you'll get a signed EBOOT.BIN
6. extract OPNSSMP.BIN from FF3 ISO, open it in hex editor, delete everything and save it as a 0 byte file. (you can keep this file and use it with the other games)
7. put the signed EBOOT.BIN and the 0 byte OPNSSMP.BIN in WQSG_UMD (with FF3 ISO opened) then close the app.
8. convert the fixed ISO to PS Minis.
