HBL

I’ve been getting a lot of complaints about my last article from the 10 Days of Hacking due to the sudden decrease of quality, and I want to apologize by creating a bonus day where I want to talk about some interesting hacks and developments.
Consider this the real Day 6 if you may.

Lets dive directly into what I consider some of the best hacks in the modern Scene of the PSP.

The PlayStop Network is a homebrew version of PSN it allows you to download VHBL and CEF homebrews. They can be transferred to your psvita with open cma. It is every similar to PSN, only on your PC but downloading homebrews is not the main feature, you can also chat with people using this app.

Now the team behind the construction of the PlayStop Network app realizes what a hassle it can be to look for all your Homebrew & Emulators need’s. So they created a Windows based portal in an attempt to consolidate all of that annoying work for you within one main functional hub. Read the rest of this entry »

Exactly 3 years ago, I announced the release of wMenu for HBL (Half Byte Loader). The early releases of HBL shipped with an embedded menu that was not nice looking and caused some headaches to our team related to the GPL license (details below). With the amount of good quality menus available for VHBL today, it doesn’t look like it, but at the time wMenu was a giant step up. Today, as the initial reasons to make it closed source are not really valid anymore, and with the recent changes to the vita Firmware (which will require additional changes to the way menus install Homebrews on the Vita moving forward), I decided to make wMenu open source.

PS Vita’s Firmware 2.10 was recently released, and we already know that Sony blocked the Apache Overkill VHBL, but this update comes with quite a few hidden surprises called “stability improvements” :o

Finding PSP exploits without owning a PSP was considered impossible because of the absence of PSPLink. But now, PSP emulators are finally starting to behave like the real thing. They have become so accurate that now it is possible to find exploits using just the PSP emulators on a PC.

Famous scene hacker Coldbird, one of the core developers of the Pro CFW, announced a few weeks ago on the prometheus forums that the “online” feature of Pro Online might become available to Phat (PSP 1000) models, after he discovered a new way to get 4MB extra ram available on the PSP.

The most requested feature ever for the HBL, is an iso loader: many “developers” promised the release of an iso loader for HBL, but nobody managed to code one so far. To understand what an iso loader is and why it won’t work on HBL, first, we have to know what a .iso file is.

Syscalls, NIDs, Imports?? If you know what HBL is, you have at least heard one of those three terms, especially “syscall”. Most time spent on developing HBL was trying to improve syscall estimation (even if now it’s broken again). Syscall estimation is one of the most advanced and important parts of HBL, without it you wouldn’t able to run so many awesome homebrews on your PSV or PSP! Most of the times, people talk about this and have no idea what they’re talking about, so here’s a brief explanation.

The exploit factory  

I just submitted an update to file “gen_exploit_config.rb” in the HBL svn, you can find the file here.

That file is experimental (and also in need of some massive cleanup), but basically it should generate almost everything that is needed to get VHBL to compile and run (including, and especially, on the PS Vita) assuming you already have an exploit and the associated binary loader.

This is still experimental, and I need to update the “how to port HBL” tutorial with this new information, but mid term this should allow you to port HBL to your game exploit in about 5 minutes (compared to about 1 week for people without experience now).

Developer Yosh (a.k.a. wth) recently found another savegame exploit on a PSP game, which he confirmed to work on the vita (video below).

Today developer SKFU was able to confirm that my port of HBL to Teck4′s exploit is still working on 1.52 (this also means that Teck4′s exploit is still here on 1.52, which had been confirmed by mamosuke a few days ago). He also confirmed that the potential vulnerabilities and other stuff he’s found so far are still available in vita 1.52, so it’s relatively safe to upgrade to 1.52 if you own a Vita (I am myself still on 1.51). On Twitter he also posted a picture of a homebrew running through HBL.

I want once again to thank Teck4 for the trust he put in me with this exploit, and for agreeing with the idea of making this exploit available to trusted people like SKFU before we attempt any public release.

Mamosuke confirmed to me today that Teck4′s exploit for the PSP Emulator in the vita is still working on 1.52. Note that it doesn’t guarantee 100% that some of the techniques used to get HBL to work on top of this exploit haven’t been patched, as I haven’t tested myself. But for now I’m confident. I might update to test that, at some point.

The 1.52 Vita firmware can be downloaded here

I managed to port HBL to the US version of Teck4′s exploit in exactly 45 minutes (including writing the savedata exploit and the binary loader),  which is a new personal record, thanks to the scripts included in HBL’s repository, and also to the fact that the different versions of the game are internally fairly similar (which is to be expected because technically the game is supposed to be the same, just translated, but I seem to recall it wasn’t that easy for the Hotshots golf exploit)
