# Davee gets PSP Kernal access on PS Vita.

> Famous PSP dev Davee just posted a youtube video showing him running PSP homebrews on a Vita. I initially thought “well, not a big surprise, he’s running his own port of VHBL to some random exploited game”, but it turns out this is much more interesting than that, as he managed to get a PSP Kernel exploit running on the PSP Emulator. Davee had hinted a few days ago on twitter that he had PSP User mode access, but it’s a surprise to see Kernel mode today.



Wololo says this means "and potentially down the road, PSP iso loaders. ", but he clearly did not watch the end of the video linked. Davee loads up Ratchet and Clank: Size Matters via the homebrew screens, which is only available as a full PSP game. This means he HAS to have found a way to load PSP isos on the Vita.

EDIT: Since I pointed out the fact to Wololo he didn't watch the entire video, he said this to me in reply: 





> You are correct in saying I didn’t watch the entire video. I updated my post slightly to add that information about Dave actually running isos from his exploit, thanks


He also slightly changed his original post to include that fact.

EDIT 2: I completely forgot this site lets you post youtube videos directly, I can have retarded moments. Here is the video:
Skip to about 5:05 to see him loading up Ratchet and Clank: Size Matters EUR version.

Thanks for making this thread, Xuphor. I'm incredibly lazy 

It doesn't surprise me Davee figured this out first. He had a track record of being a trailblazer on the PSP scene. Let's just hope this upcoming homebrew will be easy to install (i.e. free) when released.

CBA to post the video?

My main concern is that even if it is free, the CMA we'll be forced to used to install it won't block it somehow. Also that it doesn't require a PSP game already purchased, like the VHBL did. Sony pulled the exploited PSP game within 4 hours, I'm sure they'd do it again if it's another game exploit.

Interesting. Might compel me to purchase a Vita sooner than later. Only time will tell.

Now he just needs to break the sandbox =O

## dragonmaster (Mar 21, 2012)

great news i am a victim of sony myself i purchased motorstorm arctic edge they withdrew the download and they didnt return the money i lost 20 euro and they dont even answer the emails..Go homebrew

## Just Another Gamer (Mar 21, 2012)

Awesome. Nice to see some progress with Vita hacking even if its not much its still pretty good.


----------



## Mantis41 (Mar 21, 2012)

Isn't this still an artic edge save exploit?


----------



## Snailface (Mar 21, 2012)

Let's just hope Davee can push this out before Sony blocks it. 

It's not unheard of for a company to pre-patch an unreleased exploit.
Read up about DSiHax and update 1.4.2 if you don't believe me.

They don't have to block a specific exploit, they can simply block the 'process' if you will.

Nah can't be stuffed. I believe you.

Nobody mentions that it's signed eboot so he hasn't got a way to fully play them yet.

## shakirmoledina (Mar 21, 2012)

its a good start for psp on the vita. exploits within the psp vita firmware is so much better than using a game to load homebrew

All he's done is load a legally purchased PSP eboot from the PSN store. The Vita is already set for playing games so he just asked it to load a different one. Sorry folks, no ISO loader and definitely not one from Davee (he leaves that stuff alone)

You don't seem to understand what Kernel access means. By launching an application in Kernel mode, you are allowed to bypass all posts of security checks as the system assumes the integrity of the Kernel. ISO loading has been attempted in User mode but the only successful loaders work in Kernel mode, to which *he found access just now*. If he releases this exploit, pro-piracy or pro-backups hackers will take it from there, *especially* since Sony already pissed them off by not allowing PSP game transfering outside Japan and with their general attitude towards modding, hacking and homebrew. On the side note, looks like I'll be getting a Vita sooner than expected.

This is a great advance on the PSVita homebrew scene, we're near full access well... inside the PSP emulator, but still.

The only problem now is how Sony will react? Is it worth getting banned from PSN and your vita banned too for stuffs you can securely do on your old PSP?

according to the playstation website, this game only comes as a umd, it's not available for download on PSN


----------



## prowler (Mar 21, 2012)

it's still not playing ISOs, like the OP stated incorrectly.

The structure of PSN allows for user account banning, but the console itself will remain intact. Sony will probably just release an update, what else can they do?

## Coto (Mar 21, 2012)

It has gained KERNEL MODE.

KERNEL MODE = FREE ACCESS.

hrmm, so it is... guess they must just not update the website often

They can also ban the console itself, it has happened with the PS3, you get banned from PSN, try to create another account and... no, you get an obscure error code (8002A227 if I remember well) that means the PS3 itself is banned too.

But yeah so far it's just speculations from me, they'll certainly just release a firmware update for both the PSP and PSVita to patch all those holes.

## Foxi4 (Mar 21, 2012)

My bad by the way, he appears to *have* a PRX loader already.

As far as I know, this verification is based on the mac of the console which can be spoofed, but yeah, this is a code for suspending a console. That said, why would you connect when you know you're not spoofing and you have CFW? That said, I stand corrected.

IIRC there is some way of signing each console's hardware individually so they they each have a unique code, which is then uploaded in order to gain access. I might be wrong though.

## Satangel (Mar 22, 2012)

Progress, yes please! This and a PSV re-release warrants a purchase for me


----------



## eosia (Mar 22, 2012)

Guys its Davee and dont expect a release for that, before all the insults he got from stupid n00bs...


----------



## dragonmaster (Mar 24, 2012)

well  it will be interest to see a kernel access on psp mode on vita,for homebrew ,but it is better if the exploit is seen by all the scene and crackers  for some time without the fear of closing the holes on the exploit in order for them to make a beter hack
