Video: PS Vita Running PSP Homebrew via Half-Byte Loader (HBL)


Sponsored Links
140w ago - Today PlayStation Vita hacker wololo has shared a video (below) demonstrating several PSP homebrew applications and emulators running on PS Vita using their Half-Byte Loader (HBL).

To quote: In the past days I stabilized HBL for Teck4's exploit and got some major homebrews to work.

In the video below I'm showing a few homebrews running on the PS Vita. I also included Picodrive again to show that fixing the sound issue is relatively easy as it is just a setting in the emulator. Check the video below.

You can see in this video snes9xTYL (super nes emulator), Bookr (pdf reader), CSPSP, T.O.M.E. (text mode rpg), EmuMaster (game boy emulator), Zombie Crisis (FPS), Wagic (which loads about 10 times faster than on a real PSP, this talks for the improved access speed of this new memory stick format), cavestory (platform/adventure), Picodrive (sega genesis emulator), Spider solitaire, ScummVM (point-and-click adventure), Daedalus (N64 emulator, this is not DaedalusX64), FCEU-PSP (Nes emulator). Those are more or less the homebrews I [Register or Login to view links] to HBL users back when HBL was big.

Missing from this video is (unfortunately) gpsp which I couldn't get to run on the Vita, while it ran fine on the PSP. What I could see is that the emulator is more sensitive than the PSP when a thread that's currently not running crashes. I think (not sure) that gpsp somehow crashes HBL.

On the PSP it usually means that once you quit gpsp, HBL crashes. On the vita it seems to crash as soon as gpsp does “something wrong” to hbl, which is roughly as soon as it loads.

I got major homebrews to work, and now I'll focus on reporting this to the EU and US version, which both need to be brought up to speed with these latest changes.

From what I could see, syscall estimation basically doesn't work (which is what JJS discovered a while ago when porting HBL to 6.60), which will limit the amount of homebrews that can be played with this exploit, but as you can see on the video, I got a few good ones to run already

A message to haters who say I'm reusing other people's work from the PSP scene and not contributing anything new: ask yourself who made it so easy to port HBL to new game exploits in the first place.

I wouldn't be surprised if the US launch saw an even later firmware (1.6?). Hopefully the scene for Vita stays motivated and finds some reliable homebrew.

Indeed, at least he didn't reveal them specifically. I hope the launch firmware isn't very high for the US.

I hope a couple of exploits are kept secret until we actually can buy the damn thing.

Since reporting on his last flaw uncovered, PlayStation Vita hacker SKFU has found a few new vulnerabilities in Sony's PS Vita handheld gaming system.

To quote via [Register or Login to view links]: Few hours ago, developer SKFU (known for his work on the PS3, but also recently for some investigations on the Vita security) posted a screenshot of his Vita showing some HTML in what is supposed to usually show official messages from Sony’s updates or packages.

Knowing SKFU's passion for everything network-related, I'm assuming he's doing some tests using some local DNS changes... or maybe he managed to put some of his own files in an official package? That would be exciting.

In previous tweets this week, he mentioned he found 2 potentially usable vulnerabilities on the Vita

VITA is back to life, since last tweet found 2 new possibile vulnerabilities. If it runs good, news in blog this evening!

That was, however, 2 days ago, and his blog wasn’t updated since then, so I’m assuming he ran into a few issues. (the “back to life” comment refers to the official 1.52 firmware which bricked his Vita…or appeared to do so... which turned out to be that the battery had to charge for almost 24 hours before the Vita accepting to turn on, for some reason)

Obviously lots of this experimentation will probably not lead to anything, but for now, every bit on info on the internals of the Vita is interesting. Let’s keep digging

Also from SKFU (linked above) is an update on the recent PlayStation Vita 1.52 Firmware status below, as follows:

Ok guys we tested the possibilities on firmware 1.52 for a few days now. What I can confirm is the following:

  • Tech4's exploit still works
  • Wololo's HBL still works
  • Everything I research atm didn't change from 1.50 to 1.52

If that is fine for you, there's no reason not to update. Anyways, I have to mention that this can change without a firmware upgrade!

If you are online with your PS VITA, it can download and install silent updates for any application which runs in usermode and has nothing to do with system critical modules.

The good is, those updates are removed once the system is restored to the current firmware, so it would not be a major problem to remove a fix.

Wasn't it actually 1.51 as it was released around that time?
