165w ago - 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: PS Vita VHBL for Motorstorm Arctic Edge (EU) / PS Vita VHBL for Motorstorm Arctic Edge (JP) / PS Vita VHBL for Motorstorm Arctic Edge (KR) / PS Vita VHBL for Motorstorm Arctic Edge (US) / VHBL Motorstorm r141 wololo / PS Vita VHBL SVN

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.

Credits

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

Installing homebrews on the PSP was an easy task. On the Vita, until better solutions are provided, it’s quite a pain in the ass.
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 homebrews 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

Here you can download an example of packaged homebrew: Doom (http://www.mediafire.com/?yl8518xxh8v9xvp)

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 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.

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

About the claim some user have read my news post on monkeydesk and posted it on gbatemp but i or you never sayed that you have HACKed the con. I named the news with "PS Vita Hot News" and translated some posts into german.

This guy then made the post with "PS Vita hacked?" or kinda like that and his first words written was like "nabnab claims to have the ps vita hacked" but some other guyes on gbatemp with a higher rep teached them they should learn to read

Now it seems they understand. But i haven't read anything about that to copy a savegame exploit to the vita we will need your work, the debug mode enabled to get full access to file sys and place the exploit where we need them. Also im sure we can get hands on on some nice importend files of the vitas fw. But anyway they will fully understand when it's time for it

USB Debug mode allow more than we expect but it's pretty unstable for now. Every person who have a PS Vita can do it and without anything else than a PS Vita and computer

Oh yes i saw that some people said that i claim i have hacked the PS Vita. I have never said i hacked the PS Vita, i explain what i have discovered and what my investigation/work is about.

Actually some executions on the PS Vita are pretty unstable and give me some errors (a security from the PS Vita that i need to fix) but i am working on it. I keep you informed for any updates of all my work and i will show you how to reproduce it when it's easy to do but need to keep it a bit as a secret before the EU/US release.

Nothing about my works but i really recommend to use the last version of openCMA http://code.google.com/p/procfw/downloads/detail?name=opencma_r3.7z on Windows -> thanks to Virtuous Flame

Ok let's back to work now

Nabnab: Does USB debug mode allow much/anything that couldn't be done before? Or is it still in the investigation stage? Also, is it hard to get into, or is it something anyone could do?

Yep, you can always start a new thread and we can merge or promote any posts made from it to the main page.. this was our ongoing thread for the Vita FW and Content Manager so people started posting here but if you wish to start your own I'm all for that too!

I'm gonna wait the BIG BOSS if he/she (she -> just kidding what ! you never know) want to make a new Thread and move all on this thread, it's gonna be more easy to follow and update the works.

You could do a new Thread named with "Universal Vita Dev Thread" or kinda like that. But best would be to ask the boss he also can move all the stuff from here which hase nothing to do with the OCM to this new thread then.

Great about the wiki and shows you that maybe more peoples recognize your work then yourself expect

I also was surprised as i have googled for my work and have seen where else it get spreaded.

Yes like that !

I didn't know that have a PS Vita Dev Wiki until yesterday (somebody send me a private message on youtube, apparently my PS Vita stuff are available on it and i received some thanks) i didn't expect that much, it's really cool
