PS Vita Dev Wololo Unveils VHBL Success with New PSP Game Exploit

1000°
114w ago - Today PlayStation Vita developer wololo has announced news of VHBL success using a new PSP game exploit courtesy of [Register or Login to view links] with details below.

To quote from his blog: Sometimes, it’s just that simple...

Neur0n has been kind enough to share with me the details of his latest user mode exploit, so that I could help porting VHBL to his game on the EU and US versions (yes, the game seems to be available on all stores, and don’t stop reading here, it gets better).

Sometimes porting VHBL to a new game can be a pain in the rear. Many times, as I discovered the hard way, we hit a wall and have to give up after dozens of hours of investigation.

On this exploit too, had I been alone working on it, I would have given up. It seemed impossible to free most of the ram (VHBL basically needs to cleanly remove the game from the ram, in order to load homebrews instead), and the exploit ended up with about 2MB of free ram, instead of the 24MB that we usually expect.

But hey, that’s where comes the joy of working with talented people like Neur0n: he figured out, within 24hours, how to free the additional 22MB. I am not sure really how he found out, and why it works, but it damn works.

So I can proudly...

Video: PSX Games Running on PS Vita Exploit Hack Demo

350°
121w ago - Last week we reported on how the PlayStation Suite SDK allows NES emulation on PS Vita, and today PlayStation Vita homebrew developer wololo reports that PSX games are now running PS Vita through an exploit hack as demonstrated in the video below.

To quote: A few weeks ago, an anonymous hacker released a dump of the flash0 from the PSP emulator running on the PS Vita. Although it brought nothing new for the end user, it was a verifiable proof that this hacker has access to a kernel exploit running on the PSP emulator.

This week, the same dev apparently got PS1 games to run on the Vita, as shown in the video below (thanks to the Z)

For those who wonder, I have no reason to doubt the authenticity of the video, I wouldn't see any good reason for a guy who has proven he has a kernel PSP exploit to then produce a fake.

It is important to clarify that our forum member the Z is in contact with this anonymous developer, but they are (AFAIK)...

To quote from his blog: This patch fixes some crashing issues with snes9xTYL and Lamecraft, among other things.

There are still remaining issues with the VHBL port of Super Collapse 3 that I couldn't solve yet, I am still investigating: the Duke3d engine is crashing (Duke3d, zombie crisis), Daedalus seems to be crashing when loading roms (I probably won't investigate this, as Daedalus is slow on VHBL no matter what), Geometry War Portable crashes at startup, Picodrive will crash if you press the "select" button, etc...

So, still lots of incompatibilities of course, but this is getting better, and I sure hope you guys will enjoy snes9xTyl. Interestingly, I had to hook sceAudioOutput with sceAudioOutputblocking,...

From his [Register or Login to view links] feed, to quote:

An unknown VITA developer shared some interesting files, a little hint - PSP emulator and f0

From The Z on PlayStation Vita developer wololo's forum (linked above) on the release, to quote:

An unknown Vita developer has shared an interesting link some hours ago, which contains a full dump of the flash0 of the vita psp emulator - Including the kermit modules and the psvita kernel keys!

This dump can lead some professional Vita developers to kernel access, which will give us the ability to play nearly every homebrew. Backup launcher could be possible as well, but for these ones a high rank developer would be needed for programming it.

The developer says that he shared the files because...
