Guide to Porting VHBL (PS Vita Half-Byte Loader) Game Exploits

1300°
119w ago - This weekend PlayStation Vita developer wololo has made available a guide to porting VHBL (PS Vita Half-Byte Loader) to individual game exploits for those interested.

This news comes proceeding the recent Motorstorm Arctic Edge and Everybody's Tennis PSP / PS Vita game exploits.

Below is the guide, to quote from his blog (linked above): This guide assumes that you found a [Register or Login to view links] in a game, and that you were able to write a [Register or Login to view links].

So now what’s next? Well, as you probably know if you’ve gone that far, the PSP scene doesn’t really like “hello worlds”. A hello world is nice, but it accomplishes nothing, it just draws Sony’s attention to your exploit, and you know the vulnerability will be patched soon, while nobody really used the exploit.

Well, the next step is, ideally, a HEN or a custom firmware. Of course, this requires a kernel exploit, and...

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...
 

Video: PS Vita PSP HEN Demo, Kernel Access Through Exploit

1000°
121w ago - Following up on the PSP SaveGame Exploit on PS Vita from a few days ago, today PlayStation Vita hacker wololo reports that [Register or Login to view links] has obtained PSP Kernel access on PS Vita through another exploit with a PS Vita PSP HEN demo video and details below!

To quote: 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. What this means to the end user is full homebrew compatibility (unlike VHBL which is hit and miss), and potentially down the road, PSP iso loaders (the video actually shows a psp iso running). Check his video below:





The video shows a minimalist interface called “PRX Loader” which seems to be used to run the homebrews. No word...

I have broken my right arm, the VHBL portage will take time. I will try to do something on with my left arm.

The exploit works on Vita.. See video:





 

Video: New PSP Exploit Surfaces, PS Vita VHBL Port Incoming?

1000°
122w ago - Following up on his PS Vita VHBL Motorstorm Arctic Edge hack from last week, today PlayStation Vita developer wololo has announced news of a new PSP exploit discovered by Xerpi with a demo video below!

To quote: I honestly stopped counting how many PSP "hello world" exploits in PSP games have been announced over the past months, but these exploits are getting a second life now that they symbolize a possibility for homebrews on the PS Vita.

This time it's scener Xerpi who found an exploit, which I haven't confirmed yet, but I should be able to give it a try sometimes this week. Will this lead to a VHBL port/release? First we need to make sure this game is actually available for the Vita. After that, only time will tell, but I'll do my best to help





Congrats, xerpi!

Note: Let me emphasize that I am aware of several psp game exploits being available, and releasing VHBL for them or not is basically up to their authors. I'm of course offering my help to port VHBL (although my free time is limited.

Porting VHBL is relatively easy, but even with some experience, from...
