178w ago - Following up on the rumor from last week that a PlayStation Vita Hello World was achieved through a PSP Save Game exploit, today established PSP hacker wololo has confirmed it and stated that a Half-Byte Loader (HBL) is incoming!

To quote: Last week, an exploit on the PS Vita through the PSP emulator was announced by Mamosuke. The exploit was found by Teck4, and, we won't stress it enough, is a PSP exploit that gives us user mode access within the PSP emulator on the Vita. So this is not a Vita exploit per se, but it's still very cool.

Mamosuke confirmed this with a video a few days ago, and today I was able to confirm the exploit myself as shown in the video below (and I must admit that I spent way too much time working on that basic flame effect). The video below shows the exploit running on both a PSP 1000 and the PS Vita.




Here's also a screenshot since there is not autofocus on my stupid camera.

I spent a good amount of time today confirming some of my hopes that it will be possible to run HBL, at least to some extent, with that exploit. It doesn't mean I have ported HBL to the Vita yet, but I have strong hopes this will be possible. A handful of hackers are working on bringing HBL to the Vita (I won't mention their names here as I don't know if they want to be contacted on the subject), and it should be "relatively" easy to get something to work fairly soon.

(It should be noted though that the Vita is quite sensitive and crashed on me several times when it went into "sleep" mode from the exploit screen from there - am I just paranoid? - it seems it is impossible to reboot the machine for almost 10 minutes, which made me think I had bricked my vita could it be a anti-hacking security? If the console detects several crashes, it takes longer to boot, in order to prevent brusteforce types of attacks?)

I won't discuss any release yet, it doesn't depend on me only (this is, after all, Teck4′s exploit), but if I have my opinion to give on the subject, I would suggest to wait until the Vita is released in Europe and in the US. This gives us some time to polish HBL on this device, and hopefully the vulnerabilities we use to run HBL won't have been patched by then.

This is of course just a challenge with little to no practical interest once we publicly reveal the exploit (in particular, the game used in it), it will be extremely easy for Sony to patch it (or remove the game from the Playstation Store), so probably only a few people will be able to benefit from it but only time will tell, there is still hope, after all, that Sony doesn't care about a tool that allows us to run user mode psp homebrews in a sandboxed emulator.

No big update of my works but here the driver PS Vita libusb a made for Windows (x86/x64). you don't need to use anymore the generic driver ps vita from Sony.

Oh yes just to clarify about the 3 python script i made. This is nothing comparatively to the full script i'm making, the 3 script are here to show you that you can communicate with the PS Vita, about the helloworld, funny how some people didn't understand how the python script works.

First : I ask if the PS Vita is connected to my comp
Second : I ask to the PS Vita the information of the USB configuration
Third : I send a message to the PS Vita and the PS Vita confirm the reception with a Hello World.
The PS Vita can't really answer to a question but can confirm that received the question. I write the answer Hello World for the PS Vita to confirm the message a send to the PS Vita has received, if the PS Vita didn't received the message, i would have a error and not the print hello world.

Is like every Hello World, it's you write the HelloWorld and it's the product show the Hello World but the product don't understand what that mean.

You need to think that have different possibility to make a hello world possible on every platform.

Sure that the Hello World is not impressive but like i said it's one of the investigation that show you where to work.

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.
