PS Vita Hacker SKFU Confirms PlayStation Vita PKG AES Key Changed


Sponsored Links
158w ago - Following up on the PS Vita 1.50 Firmware announcement comes news this weekend from PlayStation Vita hacker SKFU who has confirmed the PS Vita PKG AES Key has changed.

To quote from his blog: I just got my tried to unpack the [Register or Login to view links] for PS VITA and sadly I have to say that the AES key for PKG encryption and decryption changed.

The PKG's I used for my testings were pretty old and the key update was expected. Nevertheless it's a bit disappointing but a new nice challange

The PS3 can decrypt the new packages on firmware 4.00 which contains the new PS VITA PKG AES key for the PS3 <--> PS VITA content exchange feature. This means we can decrypt and get the content of the PS VITA PKG files via a 4.00 PS3. Sadly there's no solution to re-encrypt it again, yet.

Let the games begin! (again...)

Following up on his PS Vita VHBL Motorstorm Arctic Edge release, this weekend PS Vita and PSP hacker wololo has revealed that Everybody's Tennis (known as Hot Shots Tennis in the US and Minna no Tennis in Japan) contains a vulnerability that could lead to the execution of external code and has since been removed from PSN by Sony.

To quote from his blog (linked above) as follows: Dear Sony, it has come to my [Register or Login to view links] that one of the PSP games available on the PlayStation Vita has a vulnerability that could lead to the execution of external code by some malicious users. Therefore I am writing this blog post so that you can patch the game or remove it from the PSN store as soon as possible.

Preferably, I suggest you take the money from your clients first, and prevent them from downloading the game afterwards, just like you did with Motorstorm Arctic Edge, 3 weeks ago. This way it will be a win-win situation for you, and you can always blame it on the hackers later on.

As a matter of fact, I have discovered that some "hackers" (I prefer to call them terrorists) have already prepared a [Register or Login to view links] which, using this vulnerability, could allow people to run software that would be extremely dangerous for your business, such as 20 year-old 8 bit games and 154 different versions of pong.

I think this puts your business at risk, and I've tried to stop those vilains by all means necessary, but sadly it seems they are not breaking any law. Hopefully, giving you the name of the game will help you to take some efficient action.

Those people are clearly wrong in their mind to try to play crappy open source software, when they could enjoy a great game such as Ridge Racer for less than 10$ a track, (which is clearly not a ripoff compared to the price one would have to pay in the real world to drive cars that completely defy the laws of physics. Although on that subject I woud like if you could help me, as my version of the game seems to be blocked in "demo mode" for some reason. All the 5 cars have exactly the same specs, so surely there's something I've done wrong somewhere.)

I digress. The name of the game is Everybody's Tennis. It is also known as Minna no tennis in Japan. Thankfully the game is not available on the US Vita store, so this should limit the problems on your end. I heard however that these hackers have prepared a US version of the hack just in case that version is being sold somewhere such as the HK store. I also heard people can buy the UK version from the US if they buy some PSN cards from resellers on ebay and other sites.

If I may give some advice, I think this is not secure enough. True, you did a good job in preventing people from buying games outside of the country they live in (and being a French living in Japan, I can't tell you how much I appreciate the fact that I can't buy any game on the French PSN, this is exactly how globalization should work, and it helps me sparing lots of money by not buying any game), but I think in order to avoid future hacks, you should simply prevent everyone from buying games on the PSN, which will guarantee you a complete control of the market.

The hackers also announced they would release their hack a few hours or days after they announce the name of the game being used. They claim this only allows people to run "homebrew" games and that in no way it allows people to play pirated PSP or vita games, but I think this is not an excuse to hack.

I realize it is saturday evening for your teams in Europe, and Sunday morning in Japan. I hope you will not have to wake some people in the middle of the night just to take action, I would have chosen a better time, but I myself have very little time to blog outside of weekends.

Hoping that working together we will be able to stop hackers. I seem to be one of the few people on Earth who understand that the real enemies of the Vita are not your poor marketing techniques, the terrible software such as the "back to the 90′s" netfront browser, the bad launch lineup, the delays on the playstation suite, the recent downgrade from 5 to 2 allowed copies of any given psn game, and the increasing competition of smartphones that all have better CPUs than the Vita. No, the real enemies are those people playing Lamecraft, who are clearly killing the videogame market, so let's destroy them together.

Please pay extra attention to the dev known as wth, who apparently is behind this whole thing, as well as Teck4 who apparently helped him for the Japanese version of the hack. I also heard that somes guys named mamosuke and msparky83 were involved in the testing. It would be good if you have a way to maybe track these guys' phones or something. Or maybe you can simply sue them, I heard it's something you do very well.

Yours truly, W. Ololo

Update: Following our discovery yesterday that the Honk Kong version of Everybody's Tennis was different from the 3 other ones, wth got to work and adapted VHBL to this version. I haven't tested this, but hopefully people who bought the HK version of Everybody's Tennis can confirm if it works.

WTH also hinted to me that he might be able to get rid of the current limitation on the European version of the exploit, in which people have to switch the language of their console to French before running VHBL. Stay tuned.

Thanks to the great work of wth, here is the long awaited second release of VHBL. Those of you who missed the Motorstorm exploit probably had a chance to grab a copy of Everybody's Tennis before Sony pulled it (let's be happy, they gave us a bit more than 30 hours this time, last time was 8 hours). If not, well stay tuned, there are still other PSP user exploits lying around, and I'm sure something will come eventually.

But let's get to the real subject here, this new release of VHBL. Sadly, I didn't test it myself on my Vita, only on a PSP, so here's to hope everything will go well. The full port has been done by wth (a.k.a. Yosh), with some help from Teck4 (JP exploit), and msparky83 and mamosuke (testing). I wasn't involved in this port, so all credit goes to these guys. I want to thank as usual all the developers behind HBL, who made it relatively easy to port, in particular m0skit0 and JJS. Yosh also adds special thanks to dridri85, Zer01ne, Truthkey, and other devs who kept this a secret while it was being developed. From the readme:

  • HBL port to the EU/US/JP versions of the exploit by Yosh
  • EU/US Exploit by Yosh, JP Exploit by teck4, discovered by Yosh
  • wololo for the help

Thanks go to:

  • All the devs who made HBL what it is today, in particular m0skit0 and JJS
  • dridri85, Zer01ne, Truthkey and all the other devs who kept the secret, that's much appreciated guys
  • Monsieur2T2R for the cool VHBL icons/wallpapers

Apologies to all the people who bought the Everybody's Tennis game from the HK store, it turns out that version is a 4th version of the game for which no exploit was prepared yet.

The HK version of the game is difficult to find, so if you happen to own that game on your PSP and are a bit technical savvy, you might want to give it a try and port VHBL to it. I'm convinced it's just a matter of time, it just takes one guy.

So, to whoever will do that port, thanks in advance, and to people who are waiting for the HK version of VHBL, please stay tuned. Neither wth nor me were actually aware that the HK version was different from the other 3, so it might take a while for something to be ready, but we're not forgetting you.

HOW TO INSTALL AND RUN HBL ON EVERYBODY'S TENNIS

  • It is *strongly* recommended that you turn of all wireless connections on your PS Vita, and that you use OpenCMA on your PC instead of the regular CMA. This is recommended because otherwise your console has a way to force you to upgrade the firmware even before you get a chance to use the exploit.
  • Extract the HBL archive matching your version of the game in your CMA PSP Savedata folder. It is a folder on your PC named PSSAVEDATA/[lots of random characters here]. If you don't know where it is, check your settings in CMA
  • Connect your PS Vita to the PC through the CMA, it should give you the possibility to copy the savedata from your PC to the Vita. If not, you probably extracted it in the wrong folder. (Note: You will also want to install some homebrews with a similar technique, read the section below)
  • Important for owners of the European version of the game: Before running Everybody's tennis, you need to change the language of your PS Vita/PSP to French. This is a limitation of the exploit for now, this might or might not change in future revisions. you can of course switch your console back to your own language once you are done playing with VHBL.
  • To run HBL, start the Tennis game, select "Continue" in the Main Menu. At this point, HBL should start

HOW TO INSTALL AND RUN HOMEBREW

Installing homebrew on the PSP was an easy task. On the Vita, until better solutions are provided, it's quite a pain in the rear. The CMA will only let you copy savedata, and will not recursively browse folders. To address this, HBL comes with a tool that can extract archives with a specific structure.Packaging the homebrew for installation on the Vita:

1) download PSP homebrew from your favorite Web site (wololo.net/downloads)
2) extract the homebrew somewhere on your hard drive, and with your favorite utility, zip it again with the *store* setting (no compression), in a file that you will name "install.zip"
3) take any PSP savedata (but not the one used for HBL!), and add the "install.zip" to that folder, in your PC CMA folder. so your PSP Savedata will look something like this:
in folder PSSAVEDATA/1a2b3c4def5678/UCUS12345000/ (or something like this) you will have the following files:

  • ICON0.png
  • PIC1.png
  • DATA.bin
  • PARAMS.SFO
  • install.zip

Installing:

1) run OpenCMA on your PC, and CMA on your Vita
2) copy the previously packaged SAVEDATA (see above) with your homebrew in "install.zip" on your Vita
3) run HBL (how to run HBL is explained in the previous section)
4) navigate with the HBL menu to the SAVEDATA folder, then go to the folder you just downloaded (in my example, UCUS12345000), and clikc cross or circle on it
5) At this point, the HBL menu should ask you if you want to install the homebrew. select yes, and wait until HBL is done extracting your homebrew
6) The homebrew is now installed, and you can run it by going to the GAME folder, if everything went well, a new subfolder with your homebrew has been created here, and you can run the homebrew

OpenCMA (wololo.net/downloads/index.php/download/1252) is strongly recommended to install if you want to use VHBL. Open CMA is a tool by Virtuous Flame that allows you to copy files from and to your vita without being connected to the internet. This is useful, especially if you don't want Sony to forcefully update your firmware.

Update 2: PlayStation Vita developer wololo[ has updated (wololo.net/wagic/2012/04/15/new-vhbl-version-for-everybodys-tennis-gets-rid-of-language-limitation-in-eu-version/) the VHBL version for Everybody's Tennis, which now gets rid of language limitation in EU version. Downloads:

  • [Register or Login to view links] (All EU versions except Italy)
  • [Register or Login to view links] (Italian version)
  • [Register or Login to view links] (JP/US, also works with the EU version, but for EU the links above are recommended)
  • [Register or Login to view links] (HK)


To quote: "Developer wth released today an update to his Everybody's Tennis exploit, specifically for the EU store. This change does not improve homebrew compatibility, but will work independently of the language of your console. Yes, finally, no need to switch your console to French or Spanish.

Even though there is no new homebrew compatibility, I'm sure this will be a welcome update for those of you who are using this exploit."

Well, I saw the news and downloaded the files, then after reading more carefully to get it to work, realized I might as well delete everything. I don't have Motorstorm, can't get it (now), and the space required on my little 4GB stick greatly outsizes the actual homebrew I'd like to run. So, nice proof-of-concept, and many thanks to wololo for actually releasing something useful.

As previously reported, PlayStation Vita developer wololo has now released the PS Vita Half Byte Loader (VHBL) and updated the source code for the Motorstorm Arctic Edge buffer overflow exploit according to plan!

Download: [Register or Login to view links] / [Register or Login to view links] / [Register or Login to view links] / [Register or Login to view links] / [Register or Login to view links] / [Register or Login to view links]

To quote: If you are lucky enough to be one of the few owners of Motorstorm Arctic Edge, VHBL is now available for download.

Please report Success/Failure here or on our forums (wololo.net/talk). As you will see, installing homebrews is a bit of a pain, so if you’re a good hearted guy who understands my explanations in the readme, please feel free to share homebrews packaged “correctly” for VHBL.

Note: you can have several homebrews in one “install” file. For example if you zip all your PSP/GAME folder, all the homebrews in there can be installed at once by VHBL.

HBL port to the KR/US/EU/JP versions of the exploit by Wololo. Thanks go to:

  • Teck4 for the Motorstorm exploit
  • All the devs who made HBL what it is today, in particular m0skit0 and JJS
  • Mamosuke, j416, Some1, and all the other devs who kept the secret, that’s much appreciated guys
  • Monsieur2T2R for the cool VHBL icons/wallpapers

For now, I’m off to bed, but I'll be sure to post more in the days to come, with updates, tutos, technical explanations, etc...

Vita Half-Byte Loader

Vita Half-Byte Loader is a project to port the PSP homebrew loader HBL to the Playstation Vita, through the PSP emulator on the Playstation Vita.
For the latest news about Vita Half Byte Loader, check the VHBL Category on this blog.

Half-Byte Loader (HBL) is an open source Homebrew Loader for the Sony PSP and the PS Vita. It allows to play fan-made games on any PSP up to firmware 6.60, and on the Vita up to firmware 1.61. HBL allows to run emulators for the Game Boy, Nintendo 64, Sega Megadrive, NES, Super NES... and many other applications.

Disclaimer

  • VHBL does not technically allow you to play any pirated PSP or Vita games.
  • Although VHBL is free and open source, the current version relies on a vulnerability in a specific PSP game (Motorstorm Arctic Edge) that you need to buy from the PSN. VHBL comes with no guarantee, especially I cannot guarantee it will work on your Vita, so remember that you pay for a PSP game, and not for anything else. I do not do refunds for the money you gave to Sony
  • It is super easy for Sony to patch the vulnerabilities used by this tool, given the amount of control they have on the PS Vita. VHBL runs fine on firmware 1.61, but for all I know it is possible for Sony to patch the game’s vulnerability without a firmware update. So, once again, before buying the game and downloading VHBL, you need to understand that you pay for the game, and VHBL is a bonus that might or might not work

How to Install and Run HBL

  • It is *strongly* recommended that you turn of all wireless connections on your PS Vita, and that you use OpenCMA (wololo.net/downloads/index.php/download/1252) on your PC instead of the regular CMA. This is recommended because otherwise your console has a way to force you to upgrade the firmware even before you get a chance to use the exploit.
  • Extract this HBL archive in your CMA PSP Savedata folder. It is a folder on your PC named PSSAVEDATA/[lots of random characters here]. If you don’t know where it is, check your settings in CMA
  • Connect your PS Vita to the PC through the CMA, it should give you the possibility to copy the savedata from your PC to the Vita. If not, you probably extracted it in the wrong folder. (Note: You will also want to install some homebrews with a similar technique, read the section below)
  • To run HBL, start the Motorstorm game, select “Load” in the savegame menu, open the HBL savegame, then go to “Wreckreation > Time Attack” and select “No”. At this point, HBL should start. See the video below for details:








Motorstorm Arctic Edge VHBL r141 Changelog:

  • Games using the Quake Engine such as KurokPSP (and probably Quake itself) now work!
  • Geometry Wars Portable, which was also not working for some reason, is now working fine.

How to Install and Run Homebrews

The CMA will only let you copy savedata, and will not recursively browse folders.

To address this, HBL comes with a tool that can extract archives with a specific structure.

  • ICON0.png
  • PIC1.png
  • DATA.bin
  • PARAMS.SFO
  • install.zip

Here you can download an example of packaged homebrew: Doom ([Register or Login to view links])

Installing:

1) run OpenCMA on your PC, and CMA on your Vita
2) copy the previously packaged SAVEDATA (see above) with your homebrew in “install.zip” on your Vita
3) run HBL (how to run HBL is explained in the previous section)
4) navigate with the HBL menu to the SAVEDATA folder, then go to the folder you just downloaded (in my example, UCUS12345000), and clikc cross or circle on it

6) The homebrew is now installed, and you can run it by going to the GAME folder, if everything went well, a new subfolder with your homebrew has been created here, and you can run the homebrew

Quick Installing/Using VHBL FAQ

As you might have noticed, using HBL on the PSP wasn’t easy, but on the vita it’s even worse. That’s partially because of the many limitations enforced by Sony’s CMA, but also because I was too lazy to make too many improvements to HBL and the wMenu (mostly because I didn’t want to spend too much time on a tool that people might ditch at the next Firmware update)

Anyways, here are quick answers to the most frequently asked questions I got over the past 3 days

Do I really need to have Motorstorm Arctic Edge in order to run VHBL?

For now, yes. Later versions of VHBL (if any) might rely on other games, but for now, MAE is required.

I don’t have Motorstorm Arctic Edge, and I can’t find it on the Store, where do I buy it?

You can’t. Sony removed the Game from their store on March 2nd.

Is there a way to install Motorstorm Arctic Edge even if I didn’t buy it in time? By sharing my account with somebody, or downloading it from somebody’s server?

No. Each copy of the game is tied to the account that bought it, and Sony made it so that the game cannot be re-downloaded for now, even for those who bought it.

I tried to copy the exploit savedata, but The Vita tells me the data is corrupt, and refuses to copy it?

This seems to be happening mostly with the JP version of the VHBL exploit. Some sites have reported that if you mark all files in the savedata to not be read only, this will work. I’ll see if I can fix that in a future release.

I put a homebrew in “install.zip” as you explained, but the HBL menu isn’t able to install it. I’m pretty sure I did things right the “install.zip” file has to be a zip with “no compression” (also known as “store”. This option is available in most compression tools. I recommend 7zip.

I installed an emulator (or a Book reader). Now I want to install roms (ebooks) for it, do I have to reinstall the entire emulator?

In theory no, if you put the full path in your install.zip archive. For example, if you have a rom named “wololo.bin”, and want to put it in PSP/GAME/Snes9xTyl, just create all those folders, put the rom in it, and create an install.zip that will contain your rom (install.zip/PSP/GAME/Snes9xTyl/wololo.bin).

Practically, that can be difficult to remember, in which case the best is indeed to re-install the full homebrew with the roms in it. The benefit of this technique is that the HBL menu will detect the EBOOT file in your archive, and automatically understand where you want to install your stuff.

Note: you can have many homebrews in one install.zip, as long as they are in different subfolders. I personally simply zipped my entire PSP/GAME subfolder from my PSP Go, and installed the result on my vita)

How do I delete homebrews?

The easiest way is to go in the CMA on your Vita, and delete from there. Unfortunately it makes it difficult to know what you’re deleting. An alternate way is to install PSPFiler and use it to delete. I’m hoping to see some volunteer devs out there to provide alternatives if possible
