Half-Byte Loader

Heads up:Call of Duty: Infinite Warfare up for Preorders. Legacy Edition $63.99 (20% off) for Amazon Prime members

What is it?

If you have firmware 6.60 or below, you might want to install a Custom Firmware rather than HBL.
This page is the official Download page for Half-Byte Loader. If you have questions please check the FAQ. For the latest news about Half Byte Loader, check the HBL Category on this blog.
Half-Byte Loader (HBL) is an open source Homebrew Loader for the Sony PSP. It allows to play fan-made games on any PSP up to firmware 6.39. HBL allows to run emulators for the Game Boy, Game Boy Advance, Nintendo 64, Sega Megadrive, NES, Super NES… and many other applications.


The Version of HBL you need to download depends on the firmware of your PSP, and is independent of the model (it works on all models, 1000, 2000, 3000, and PSP Go). Click on the firmware installed on your PSP to be redirected to the appropriate download page:

Additional downloads

If you’re looking for good homebrews that run on your PSP, don’t look any further, those are 15 games and utilities that will keep you entertained for hundreds of hours.

How to use

Check the README.txt file in the zip file :)

More Info

HBL is a work in progress and sometimes it might fail to load your favorite homebrew. However we believe it is harmless for your PSP and I personally test my work on several PSPs before releasing it. We are also confident that this program cannot “brick” your psp and it will not void your Sony Warranty.

HBL is open source, the compiled versions I provide are a compiled version of the sources available freely here

  11. Paco

    Is it starting the Homebrew directly from the game, or u can run it from the psp menu?

    • toBsucht

      If you talk about hbl no it cann´t start a homebrew from the psp-menu =xmb ;). The good thing about hbl is you can use it to start some brews from any floder. If you use tn-hen or pro hen you have to place the brews @ games floder to start them from xmb.

  12. Paco

    I wanted to ask can i update to PRO directly from the save data exploit

  13. ninesix

    what a noob

  14. PSPGo-6.39

    ok PSP Go 6.39 going to black screen, lights flash and then goes off

    Extracted files to root and PSP/Games as instructed. But was going the black screen reset thing.
    I then look back in my Root/PSP and find the .h and hbl folder moved into there??
    So moved them back to Root, held the power switch up to power off completely, powered back up and then ran the hbl and it launched ok.

    Just thought i’d note to help anyone out :)

    Half-Byte Loader made my life better!

  28. May I just say what a comfort to discover someone that truly knows what they’re discussing on the net.
    You definitely know how to bring an issue to light and make it important.
    More people must look at this and understand this side of the story.
    I can’t believe you are not more popular given that you
    definitely have the gift.

    MuffinHead Smith: I completely agree, but I’m also hoping that my reply will be seen by other people. I’ve seen many videos claiming that they have a HEN ready for the PSPGo (by the way, except for Team Typhoon, these claims are all lies), and pretending they won’t release it because I’M against it, which is a complete lie. I don’t want people to believe that I’m in a crusade against ISOs when actually I just don’t care.

    In other words, I’m not really replying to conkertheking himself but to the incredible amount of people who believe that I give a sh#t about their desire for pirated games :)
