Half-Byte Loader “XMB” version

What is it?

This page is for the “XMB” version of HBL, a version of Half-Byte Loader that runs without the need for any “exploit” or “hack”.
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 6.37 included. HBL allows to run emulators for the Game Boy, Game Boy Advance, Nintendo 64, Sega Megadrive, NES, Super NES… and many other applications.

Important, if you have firmware 6.60, please check HBL for 6.60 Instead.

On this page you will find my own works related to the HBL: downloads for the latest version, and other cool stuff.


Latest stable release. Fast and reliable, this is the version I currently recommend. We don’t accept bug reports for this version!

Development version of the HBL. We only accept bug reports for this version

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.

Previous Versions

Nothing here yet, but for history reasons you might want to have a look at previous versions of HBL that ran on other exploits: the Patapon2 Demo, the hot shots golf games, and the Minna no Sukkiri Demo.

How to use

Unzip the archive at the root of your psp and run from th XMB. Check the README file of the archive for more info :)

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

    • Chris K.

      if ur looking to run iso/cso, heres what 2 do.
      1. get 6.35 hen. the signed one of course
      2. get a psp app thats called iso tool.
      3. convert it and boom u have a backup of your game. also 4got to mention u NEED promethus set to np9660 mode not m33 driver

      • kasutbiru

        hai there, just a simple and quick question here,

        1) what is promethus?
        2) what is np9660 mode?
        3) what is m33 driver?
        4) can i really play iso/cso game on 6.35?

        thank you very much. 😛

  5. am33r

    Thank you wololo for porting the HBL to the XMB. This is good for everyone as we now don’t need exploits. I am assuming this HBL is somewhat signed.

  8. blueyoshi3

    I AM SO CONFUSED!!!!!!!!!!!
    will someone help me???
    here is my email
    please send me specific instructions on what to do cuz i have no idea what i am supposed to do.

    • clockdryve

      What kind of PSP do you have? What firmware are you running…Do you know what the ROOT of the memory location is…..and do you know what the XMB is?? Those are the FIRST things you need to do.

  9. blueyoshi3

    if u can help, thanx

  10. blueyoshi3

    where is the root on the psp go there is 2 roots there is the mln root and the mp root… which one do i use and where do i put it… still confuzzled… can someone draw me a diagram haha

  11. clockdryve

    The ROOT location you need is when you connect to PSP with DATA cable….you see area that has PSP,PICTURE,VIDEO,…..folders. That is the ROOT you need (just drop items onto that area….NOT into a folder unless directed to do that). The folders that “say” ROOT on them are NOTHING for us. You will need to make an ISO folder for the ROOT location too.

  12. Mad-mark

    Tell me, please, does it support the 1.50 hombrews?

  13. blueyoshi3

    THANKYOU THANKYOU THANKYOU THANKYOU… I REALLY NEEDED THAT INFO, and i know what all that stuff is… it is version 3.37

    • clockdryve

      @blueyoshi3, do you mean Version 6.37 PSP??

      @Mad-mark, No….this does NOT work for 1.50 homebrews. But MANY 1.50 homebrews have been ported over to 3.xx or above. What are you trying to run that is 1.50 Homebrew??

      • Mad-mark

        I’m trying to find a workable psx emulator, but I have only for 1.50. eLoader doesn’t work on my psp-3008 6.35 PRO.

  14. Rowan

    • jan doe

      same here man i want to know the same question

    • bloosmagoos

      Hey, make sure the HBL that is in the root of the zip file goes in the root of your psp…there should be hbl folder, readme.txt, and h.bin files. Then, the HBL folder inside PSP>GAME in the zip file goes into PSP>GAME on your PSP. Then it should run.

      • anon

        hmmm…I did the same as you instructed, yet my screen still goes black after selecting the HBL EBOOT on my psp…
