Half-Byte Loader

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:

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

    It’s silly, but can someone test YamaIRC on HBL, I can’t use it. But I don’t want install CFW. Can it be about prx drivers? Because Xplora don’t start because it can’t load .prx file.

      http://www.mediafire.com/?lqw7oogfqnbxh75 YamaIRC signed for ofw.
      (if you still want to run it with hbl try this ver. but unsigned [orginal])
      Check out signed homebrew list @ wololo.net/talk
      Xplora is also signed but not the latest version(~2)
      .. i doubt it can run on hbl.. maybe ver. 1.3 or 1.6


      1. albru’s avatar

        OK, I fix the YamaIRC (now I have another bug with it), but what with Xplora?


        1. toBsucht’s avatar

          What? Use the signed or the same version unsigned with hbl^^
          Maybe try multitasking or dosboxmanger
