for example, make FOLDER=lifeup will compile HBL for the Motorstorm (EU) exploit.Īs you guessed, you will create a folder dedicated to your own exploit. Compilation is fairly easy, but in order to compile the HBL for a specific exploit, you have to specify the folder of the exploit.
In order to compile it, you need the PSPSDK (which you probably already have if you wrote a binary loader). The sources of HBL can be downloaded here (SVN client required) (As I write this, it is recommended to test compilation with either the Mototrstorm or the Everybody’s tennis exploits, as we might have broken backwards compatibility with older exploits) The first step is to get the HBL sources, compile them, and if you’re motivated, test them on an existing game exploit, to make sure the copy you have works correctly. To complete this tutorial, you need basic shell skills, a working pspsdk, a working game exploit and the associated binary loader / hello world, a ruby interpreter, and basic ruby skills (usually, if you know any other scripting language, you’ll figure it out easily, there are not so many changes required). Most Game-specific files (except one) go in a subfolder that I will describe below. HBL was designed to be easily ported to new game exploits. Additionally, depending on your game (and its function imports), the compatibility and speed of homebrews might vary. In theory, HBL will work on future firmwares, but of course new kinds of security might be introduced in new firmwares. This tutorial is valid at the time of its writing, for all games, and up to firmware 6.60 (Vita firmware 1.61). HBL opens the door to lots of legal contents on the PSP and the Vita, and we designed it so that porting it to your game exploit can be done fairly easily. A much more doable task, that will make lots of people happy, is to port HBL to your exploit. Of course, this requires a kernel exploit, and we know how these are difficult to find. Well, the next step is, ideally, a HEN or a custom firmware.
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.
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”. This guide assumes that you found a user mode exploit in a game, and that you were able to write a binary loader. I just updated the main file needed to create the exploit, so the timing is right. In this guide I will explain how to port Half Byte Loader to your game exploit, and in particular to make it work on the PS Vita. This guide is the second major revision of a guide I wrote a year and a half ago.
