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:

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

    • tobsucht

      yes it does with close to zero brick risk .. can you not run the new pro b6 hen for ofw? go here http://wololo.net/talk note you most likely can downgrade your psp now with some1´s downgrader

      • sawyer

        bless you 4 reply so if hbr 113 works with 6.39 i guess i will update so i can go to psn

        • toBsucht

          as jack replyed the downgrader is working well and easy.
          To go to psn you can fake version with a hen or simply use pro-b6 for fw6.39 ^^best fw for me 6.20 😉 ^downgrade to a lower ver. maybe brick your psp^

  8. jack105

    Guys, anyone there want to downgrade from 6.37/6.38/6.39 oFW, just visit www,psp-hacks.com, you can now downgrade to 6.20 and have TN HEN and play ISO’s from there, you can go to 5.50 gen cfw’s,

  9. noob

    is there an application in psp go that fully capable of doing the bluetooth system of it, like transfering files, example music from psp transfering via bluetooth to cellphone?? thnx just asking

  10. JeeVeS

    Well, I haven’t been here in ages…since downgrading to 3.71 rather than 5.00 by accident, i’ve attempted to upgrade, but my PSP just give me error 8001005, saying it cannot read my Memory Stick!!!

    I know it’s not a fake, and I’ve never had any trouble with it before now. Is there any chance that someone out there could help me? Thanks in advance!

  11. sawyer

    i like hbr 113 because i can run it from game menu with no trouble i dont know what i have 2 do for any other homebrew enabler plus if i down grade then when i buy a new game that requires a high firmware i have the latesest ofw with no trouble , can u understand how i feel ? homebrew is kinda new 2 me and i kinda stumbled on to hbr113. i like it allowing me to put dosbox, scumm, amiga, frotz, n64 (which runs without having to run hbr113), and other homebrews . i dont understand what an iso is or all that

  12. sawyer

    i am not really smart on what iso , beta, and some other lingo means. I like hbr113 cause all i have 2 do is goto game menu and run hbr113 then psp lets all emulators work. dont know if putting other enablers on my psp would confuse me. kinda like if it aint broke dont fix it. funny thing though, my dad has vending co. n made super pacman, donkeykong etc… very smart man with eproms (sp?)

  13. GOKU

    Hi Bro

    I bought new PSP -3004 Ver 6.35,
    How can i play the downloaded games in the PSP , Naruto, God of war.
    Actually my friend told me that i should crack/Hack to play pirated version games, i usually download from the torrents , Can you pls guide me in detail.

  18. Anthony

    If You Have HBL on Psp Go And You update it will you lose your hacks?

  19. Ben vd Heijden

    Sorry but I am getting completely confused by all this info.

    I have PSP 3004 with firmware V 6.37 datecode D1 and I have the feeling after reading info on this site that I can play Iso games on it. However I do not know how to manage; do i Need Half Byte Loader, e2boot, any Homebrew Enabler (HEN) or maybe something else ?
    Can anyone please inform me what I best can do to play my favorite games. like Fifa and Need for Speed . And also what are the risks (apart from warranty void) of doing these changes to the product !

    Many thanks in advance


  20. toBucht

    Ben you have to update to 6.39 ofw (OrginalFireWare) then you can use pro-hen 6.39 (8b) or tn-a 6.39 (may tn-“extended”)°°googel them, they got iso loading options. Close to 0 risk 😉
    Datacode is not really importend anymore for 3004!
    ^^You may can downgrade but littel brick risk, make sure you know what to do if you trying downgrade (best should be some1´s downgrader)!

  21. Alex

    yeah, i stupidly updated to 6.60, and now hbl crashes, i would love ether an hbl that runs on 6.60 or a 6.59 downgrader. any links?

  30. jake

    ops me-net P.S

  31. 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.

  32. Paco

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

  33. ninesix

    what a noob

  34. 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 :)
