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

1300°
107w 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 user mode exploit in a game, and that you were able to write a binary loader.

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...
 

Sony's sceKermit Driver Surfaces via PSP Emulator on PS Vita

107w ago - Following up on his previous PS Vita developments, today PlayStation Vita hacker Davee reports that he has discovered Sony's sceKermit driver which is a communication interface for the included PSP emulator.

To quote from his blog (linked above): "Turns out he's not just a green frog! So, I've been throwing this word around recently and it's probably about time I explain. Kermit, either a protocol or perhaps a funny name (see KIRK/SPOCK) is a communication interface for the PSP emu. Specifically it allows the PSP to talk to the host.

Now, I can tell there aren't as many developers here, so I'll try to simplify for the curious minds but this stuff is pretty complicated. I'll only explain the API in detail as the lower level still need a little bit of clearing up, but here goes.

Ok, Kermit is here so that the emu can communicate to the host to share resources and other vitality. Perhaps the primary reason is that of hardware; the PSP emu is excluded from many hardware devices. So kermit sets in and allows the system to talk to the vita in order to use the hardware. Blabbering aside, this is the hardware that kermit seems to be responsible for:

107w ago - Atlus Manager of Public Relations and Sales Aram Jabbari has announced today that their reVITAlized PSP price drop event is now live on PSN.

To quote: We (the fine people at Atlus) are dropping prices on our PlayStation Store library of PSP system titles, not unlike the PS Vita's undocumented ability to drop smaller articles of sub-clothing. We're calling it...

Want to own the complete PSP Persona collection, including Persona 3 Portable, which is tied for the second-best-reviewed PSP game of ALL TIME, according to Gamerankings.com?

It is now far more affordable to do so. Also getting a drop in price is the very recent Persona 2: Innocent Sin, a stunning handheld remake of one our company's most highly anticipated games!

Always been a fan of Sting's series of Dept Heaven RPG and SRPG genre-benders? Perhaps you've always been curious to see how Knights in the Nightmare, with its incredibly novel blend of tactical roleplaying and bullet-hell action, looks and plays?

Well, for less than half the price of a new console game, you can own every PSP Dept Heaven game we've ever released (which should set you up nicely for the upcoming June release of Gungnir for PSP, the next entry in the acclaimed series).

Besides the aforementioned two collections,...

To quote: Christmas is really early this year, as Drakon, creator of the famous PSP homebrew Lamecraft, just posted an update of his game to make it compatible with the Vita.

Of course this requires you to run VHBL, but since we just released a new version of our homebrew loading tool, hopefully you are one of those who can enjoy it.

Finally, from Drakon: I made small update to LameCraft – now it’s working on PS Vita ( thanks Wololo for info ). I have also fixed some strange bugs with texture packs.
