Half-Byte Loader

What is it?

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 6.20. HBL allows to run emulators for the Game Boy, Game Boy Advance, Nintendo 64, Sega Megadrive, NES, Super NES… and many other applications. HBL is currently the ONLY way to play homebrew games on any PSP that has a firmware 5.50, 5.55, 5.70, 6.00, 6.10, 6.20, including on the PSP Go.
HBL now works on firmwares 6.30 and 6.31, but this is still a work in progress. This page will be soon updated with more stable information, but for now, owners of 6.30 and 6.31 should go to this article.

On this page you will find my own works related to the HBL: downloads for the latest version, patched games that improve compatibility, the savegame necessary to trigger the Patapon exploit, and other cool stuff.

This page will always be the first one to have a compiled version of my own patches to the SVN, as I will update the SVN and this page simultaneously. This guarantees that you can get the latest compiled version here at the SAME TIME as I upload it to the SVN. I will also announce new releases on my blog here

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

Need Help?

If you need help with the compiled versions found on this page, you can use the HBL help forums.

If you have questions/issues with versions of HBL that you did NOT download from my website , please go to the official forums (I cannot provide support for versions other than mine)

Want to Help?

HBL is a work in progress and we need your help. Bug reports, test reports, and code patches are welcome. I also accept donations if you want to support my releases.

    @NsAnE…. agreed, let’s keep criticisms and bug reports constructive and meaningful and not sounding like spoiled brats who had someone piss in thier bowl of cheerios.

    You wanna take your frustrations out on anyone, take them out on Sony for locking up the firmware in the first place…… they do have PSP forums over there ya know… lol.

    @ 0M9H4X

    no its writing in flash0

    but u should be on the hacker mode to do that

    how ?
    just press the left d-pad key and the R key and then u’l be on hacker mode and now u can copy any file to flash 0 and flash 1

    and with this u could write the files manually and then copy them to flash 0

    finally :-
    this is on ur risk and im not gonna try anything

    y ?
    1st : coz im not a tester
    2nd : coz my psp is not unbrickable

    i was gonna forget to say this:-

    i have a problem :-
    i cant psp demos and im on 5.03 and i have a cfw

    is there a program that makes makes patches to them like the E-decrypt so i can play them on cfw

    hope that is help ful
    and wish that u find the program

    sry for my bad english

  3. fabio’s avatar

    i try d it filer works didn’t no how 2 get 2 hackermode so if it works maby a exploit? i used filer4.0.for3.00

  4. john cena is the best’s avatar

    first i said press the left key wirh R or other meaning the left arrow and the R button

    second if u have a psp 3000 or the newer 2000 dont try it coz it may brick ur psp

    and if its work its not gonna be an expliot….

    its gonna be a kernel exploit or a cfw

  5. Brandon’s avatar

    After R85 NONE of my emulators have been working, I don’t know why. I have a snes and a nes emulator Snes 9x v24 and jnester. Why arent these working. I love ur work and don’t let anybody tell u otherwise.

  6. 0M9H4X’s avatar

    GUYS!
    dont talk to me like i never tried anything!
    i might not be observing the scene since the 2.00 downgrader,
    but im still no noob!

    Just try it out, it dowsnt matter if youre in hacker mode or not.
    try to copy / replace anything on flash0. It will fail to do so.

    And i said “almost” useless because with flash1 writing, you xant do anything more than:
    -Switch your controls to “japanese” which means O is OK and X is BACK.
    -Mod your PSP’s font, like i did.

    so for a CFW, flash1 access is 100% useless.

  7. antcapp’s avatar

    @OM9H4X OK…
    “Switch your controls to “japanese” which means O is OK and X is BACK”
    Can you give me a tutorial?

  8. Pier’s avatar

    can anyone tell me how can i change the display name of a psp homebrew or game?

    thx in advance

  9. Skullfire’s avatar

    I’ve tried HBL 0.95 & 0.96 before on my PSP 3004, ver 6.00 & I’ve failed. But now, 0.99 works like hell. thnx very much

    hi agian

    @ 0M9H4X

    ha ha ha ha ha ha
    i cant stop laughing
    u no why
    coz this filer ver4.4.kernel3 is ollllllllllllllllllld
    im using v 6.6 with it u can copy to flash0

    and i tried to copy this file :-
    MEMSTICK.IND
    to the flash 0
    then it said copied 1 file(s)
    then i found it there

    that means its copied with succes

    now i found how to access the flash0

    what’s next ?
    now u should work on hbl rev100 with support to filer v6.6

    then?
    find a cfw files wich are working on 6.20 and this is the last step and its the most dangerous thing coz it may break any psp

    i guess this thing will help :-
    i could use the filer v6.6 on chickHen
    other meaning :-
    filer v6.6 works on chickHen before i put cfw

    hope its helpfull

    hi
    anyone can tell me how to make patches for demos to make them work on cfw 5.03 m33-6

    i tried pspdemopatcher but it didnt work

    please help me fast

  13. 0M9H4X’s avatar

    @john cena is the best:
    ok i tried v6.6 already… back with hbl 95.
    didnt thought it will work with 99, imma try out now.
    on filer 4.4 with hbl 95, its said “1/1 fiels copied” but the file wasnt there, after refreshing flash0’s content.

    but seriously… that would mean we can use custom gameboots on OFW!

    @antcapp:
    i cant give you a tutorial, ive just seen a tool somewhere which can do this by accessing ONLY flash1 (well, as said in the tools description)
    but i cant remember the name, and either way, i dont think it will boot up on HBL.

    @5.03m33-6:
    i dont know about your firmware, there are tools for 5.50gen-d3.
    but by the way – why do you want to use DEMOS if you couls use ISOs?

  14. 5.03 m33-6’s avatar

    its 5.03 but with cfw enabler v 3.20

    the demos are :-
    naruto shippuden ultimate ninja heroes 3
    ultimate board game collection
    and motor storm arctict edge demo

    they are all works on 6.20 on my cousin psp but on mine they are not work
    and the second game works without cfw but when i tried it on cfw it says the game couldn’t start

    if you want the error code here is it :-
    80010087
    all those 3 games = the same error code

    and not only the demos not working also the apps for 1.00 , 1.50 and 2.00
    and

    and i want to use demos coz my internet is too slow so i cant download isos it takes too much time and im bored from my games

    @all:
    PSPFiler 6.6 crahses on PSP-3004 OFW 6.20 Data Code 8B with HBL 99
    1) loads
    2) memory-stick light gets stuck on orange (not flashing anymore)
    3) about 8 seconds later… psp turns off.

    @5.00m33-6:
    seriously, google is your friend:
    5 seconds spent with google returned the following:
    http://pspslimhacks.com/custom-firmware-6-20-m33-plug-in-play-6-00-games-on-5-00-m33-cfw/
    it should work for you, they are only talking about 6.20 requiring ISOs there, but why shouldnt it work for demos? give it a try

  16. 5.03 m33-6’s avatar

    hi again the plugin is not working
    so i converted the pbp to iso and there is a new error code :-
    80020148

  20. darkslyicer67’s avatar

    Hey maybe someone can make an iso emulator that can play the iso’s. So they wouldn’t be directly on the system. I don’t know how the system works besides the fact that its basically a computer but can you do something like it. Basically put the iso in a virtual machine on the psp. BTW- I HATE PIRATING..i wish i could get my old games on my psp go because it is much more convenient when traveling or on a plane ride to carry one memstick or system full of games than a case with all your games. I have tons of od games that don’t even exist in the new psp library. MY od psp broke and my nice loving parents got me a psp go. But sadly i wanted a 3000 with lowest firmware.

  21. Brandon’s avatar

    CAN U GUYS QUIT IT WITH THE ISO’s WOLOLO SAID THERE WOULD BE NO ISO LOADER.

  22. Brandon’s avatar

    For everybody that says cfw could me installed and just replace files…. it’s suicide. You need kernel access. Because not everything is loaded into ram that is needed to make a successful cfw installed.

  23. Louis’s avatar

    hi guys, is possible with gamebootsinstall v4, to instal an alternative gameboot? or my psp will brick?

  24. janneth’s avatar

    tengo un problema en mi psp go le carge los emuladores y se descargo, lo volvi a cargar y ahora solo prende hasta el menu, pero el menu no aparece y luego se apaga,

  25. nozepikka’s avatar

    @5.03 m33-6 – ok first of all.. upgrade to 5.03 GEN-C.. then install the promtheus patch from here ‘ http://www.psp-hacks.com/2010/06/19/cfw-5-03-prometheus-released-for-psp-2000-ta088v3-psp-3000-models/ ‘… it should work now… and just a word of advice.. if u cant download isos and ur friends have some games u want.. try using UMDumper.. a lil stealing never hurt anyone.. :D

  26. nozepikka’s avatar

    @Louis – if ur psp is not unbrickable don’t try it.. gameboots are stored in flash0 so it’ll either not work or brick…

  27. 5.03 m33-6’s avatar

    @ nozepikka

    ok thanks il try it

    and im doing that
    i took 4 games from my cousin and i gave him 13 demos

    and this is not stealing its called sharing

    and im not using umdumper i change the usb device to umd disc from the vsh menu then i copy them coz his games are new so i patch them first and im using the best patching programs = Edecrypt + umdgen

    and i want to say something :-
    when we go to my aunt i download isos coz they have a fast internet

    i have 20 games 3 i took from my cousin and 3 i brought them

    and i had more but i deleted them by a big mistake and i dont no how to return them ( i removed them from recycle bin )
    if u no a program to recover that files please give it to me or just tell me the name of the program

    thanks in advance

    hi guys

    i have a suggestion :-
    and im gonna say it like an example:-

    when a new game released there are 2 ways to make it an iso game

    first if the game is a umd they just copy it and then upload it

    second if the game is from psn they convert it using eboot2iso and from here is the beginning of the suggest

    you should make a converter from the iso to eboot same as the eboot2iso but make it iso2eboot

    then there is 2 ways
    first :
    try to play the eboot on hbl and if it didnt work try the second

    second :
    you know that you should have the license file or the eboot will not work on ofw
    so now there is 2 ways to have it
    1st : hack the ps store and download all the licenses and upload them
    2nd : make a program that could make a fake license files then we will put the game and it will make the license for it

    hope its helpfull
