173w 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.

You don't need to do that cfwprophet but thanks anyway !

I was thinking to make a topic and put all what i did and what i'm doing on it but i think it's a little bit too late.

Some people probably don't understand why all that are on the firmware update/CMA topic.

It would be nice if we can create a topic for all the PS vita underground stuff (not only mine)

I think it is so only because PSVita isn't yet sold all over the world. Just it will be available for all contries more people will pay attention to the psvita underground scene.

However what you are doing is great, so thank you, man!

Between 0 and 0.04 (picture shows the helloworld with my python/pyusb script available on PS3news) and about the video, i show that the PS Vita is really turned ON (and not off) and on debug USB mode.

This is just the beginning

After a test and some kernel playing.

Check the error of my PS Vita
