Port HBL to your game exploit

That’s it. You found a user mode exploit in a game, you were able to write a binary loader, so now what 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 we know how these are difficult to find. A much more doable task, that will make lots of people happy, is to port HBL to your exploit. HBL opens the door to lots of legal contents on unhackable PSPs, and we designed it so that porting it to your game exploit can be done fairly easily.

This tutorial is valid at the time of its writing, for all games, and up to firmware 6.31. In theory, HBL will work on future firmwares, but of course new kinds of security might be introduced in new firmwares. Additionally, depending on your game, the quality of syscall estimations (and therefore, the compatibility and speed of homebrews) might vary.
