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

      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 says:

        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 says:

    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.

  6. OiexD says:

    Whe I try to run mvspsp, cps1psp and cps2psp using HBL, i got a messagem “error 0x80020001 start SystemButtom.prx”

    All these emulators run fine with HEN, but crashes when loading roms.

  8. blueyoshi3 says:

    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 says:

      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 says:

    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

  10. clockdryve says:

    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.

  11. Mad-mark says:

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

  12. blueyoshi3 says:

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

    • clockdryve says:

      @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??

  13. Rowan says:

    Can we has hen please?

  14. Chris says:

    does anyone know of homebrews that’ll work on 6.35 HEN? and any cxmb themes too. thanks in advance

  15. blueyoshi3 says:

    yes that is teh correct version… does anyone know a place to get normal psp games but for homebrew like final fantasy dissidia… if u know one it wuld be really helpful

  16. blueyoshi3 says:

  19. blueyoshi3 says:

  22. chris says:

  23. chris says:

    well i got under memory stick, the game pics and it gives me option to start and i try to start them and it says that the data is corrupted. what could that be from?

  24. Kenneth says:

    I have PSP 3005 and my system software version is 6.30! I installed the hbl and it works! but I can only play those not so good homebrew games and some GBA, SNES games through the emulators. Is there any way to play real PSP games with this? I already spent a lot of times trying to find a way on how to put real psp games in it but I failed.

  25. alex says:

    OK here is the full explanation. First i downloaded the hblr1113 or something like that, the newest one. ok then i put it on the root( i know what that is), then i put wagic hombrew on my game file thingy, but when i check it says corrupted data. someone plz help me!!!!! its so confusing. also i heard there is a 6.37 exploit for psp go on youtube, someone plaz explain that to me. thx!!!

    • bloosmagoos says:

      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.

    Dude need help im just new in PSP3000, i just bought a secondhand PSP PATAPON Hack.. How to load game in patapon?

  59. toBsucht says:

    use hbl is really easy.
    Copy all files outof Wololo´s download to a free memory stick:
    – hbl
    – PSP
    – h.bin
    start hbl the same way as a SonyDemo-game
    or try to find a easy installer for example 6.XX Installer v1.4

  60. Kaorii says:

    Okay Since people obviously cannot figure this out:

    1. Open the Computer or My Computer (Depending on the Windows OS).

    2.Next Plug your PSP (with the data cable) OR plug it’s memory stick into a supported memory Card Reader

    3. Load the drive that has the PSP or it’s memory stick in the drive. When the Drive Letter (M: in my case) Opens, THAT IS THE ROOT MENU!!

  61. Alicja says:

    Yes.. It works.. But my PSP can´t read any Homebrew. :(

  62. Patrick says:

    Will this work on my PSP 2004, i don´t really know much about these things, i´m a real newbie. And one more question, wich probably is a stupid question but still, is PSP 200 and PSP 2004 the same? I think mine is a 2004 because it says under the start, selesct… buttons some numbers and in the end PSP-2004, so is it a 2004?

  63. Miqdad says:

    hey does dis work wid psp go ver. 6.37????????

  64. marcos says:

    call me stupid but i put the files n GAME,MP ROOT,n da first folder of my psp mem and it wont load what is xmb

    • clockdryve says:

      Okay “stupid”….ahh, just joking. The ROOT of memeory stick is the same place you se PSP,MUSIC, PICTURE…..folders. Just drop anything that belongs in “Root” location into that area and drop anywhere. Just FORGET about theose folders called “”ROOT….they are NOTHING for us.

  65. marcos says:

    finally got it but darn screen goes black tha HORROR

    HEy…i´m new here, just want to say thanks for your awsome work. Stupiditly (because i was curious actually) update my PSP to 6.38, i had 6.10 and my HBL stop working, now i´ve tried HBL rev113 signed official and works with the only difference that now has a black background…..i wanted to tell you my experience just in case is helpfull for someone else….see you.

  70. shawn says:

    the isos are not working :(

  71. nick says:

    only for ppl that get black screen put the hbl folder thats not the game “HBL” outside the mp_Root where u see psp, Mp.root etc. Took me a while to figure that out

  72. nick says:

    for ppl who get a black screen put the hbl outside the Mp-Root not in. Put the hbl where u see psp, Mp_Root,etc on its own. Put the HBL folder in game folder still. Took me a while to figure that out kept getting wrong advice maybe puttin it in Mp_Root works for some ppl

    • Arshdeep SIngh says:

      after all that configuration ,,,when i started the HBL!! it did start and retuned back to the XMB but no homebrew from this website is working!! hoe do i confirm that the HBL has installed correctly?
      please help
      THANK YOU!!!

      • wololo says:

        There’s not much “configuration” going on, really, you just have to unzip the archive on your memory stick, shouldn’t be too hard.
        If HBL returns to your XMB it means something wrong happened. Instead it should show you a menu.
        HBL does *not* stay in ram, it’s not like a Hen or things like that. You need to be running within HBL’s menu in order to run homebrews.

        • Somebody says:

          actually , i hv done exactly like what u tell us to do , n i hv tried run it for several times but the screen still goes black n shut off after few minutes , well i hope that not gonna break my psp, i use PSP 3001 v/ 6.35 , do u hv any idea how to get it works ?

    • toBsucht says:

      @dee recovery mode does not work with hbl. So you should give more information with hen/fw do you use.

      @nigel i hope you got it already .. it´s probatly the gba_bios.bin files which isn´t legal to share and most gpsp downloads doesn´t contain it. If you got the 16kb file simply copy it into the gpsp floder ^^and a rom file or the emulator may does not work.
