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.

Downloads




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

    “HBL is currently the ONLY way to play homebrew games on any PSP that has a firmware >= 5.50, and especially on the PSP Go.”

    Pandorable psp’s may disagree 😛 But I’m just nitpicking 😉

  3. WOLOLO says:

    I am SO happy that this works with some emus

  4. KenshynPT says:

    Picodrive works ( no sound tough)
    s9xTYLmecm (snes emul) works, but slow FPS’s
    NesterJ (nes emul) fully works
    SMS ( fully works)
    mame emul and neo geo ones dont work :c

    ** neo geo pocket does 😀

  5. wololo says:

    @Lampworker : true but I’m assuming people who have a pandorable PSP won’t come on this page anyways 😀

    Were getting so close to getting daedalusx64 to run 🙂 on the current rev (65) it freezes upon loading roms 🙁 Maybe you could look into this when you get time (personality i think you’ve earned a well deserved break.)

  20. serpistica says:

    Hi, first of all, thanks a lot!! You guys have done an awesome work!! I’m really looking forward to this =D

    I tried the Pataton 2 Exploit and it loads the h.bin with no problem….

    However, I’m having a problem when loading HBL rv66 and rv65, they simply wont load T_T. However the r31 does load, but freezes on the menu.

    I have downloaded both (r65 debug and non debug), none of them load, my PSP just turns off after 20sec or so…. And what is worst, the debug version wont create a log so I can’t send it in and help in the debugging process T_T.

    My PSP is a 3001 OFW 5.55 (the PSP that came with the Assasin’s Creed Pack).

    Thanks again and keep up the great work =D

  21. RedCloud says:

    @serpistica, you have posted on the last 2 pages ive been on lol, maybe its just a coincidence. Anyway the answer is so simple, SO very simple… just go to the hbl forum (btw this link was posted on both of the pages you asked questions on -_-) http://advancedpsp.tk/foro_es/viewforum.php?f=39 and stop asking on these pages xD

  22. Dillenger says:

    Wololo, Thanks! This is truly excellent work!

    But, I have a silly question for you:
    How many times do you think you have heard the Patapon Theme song?

    I have been following the HBL loader since it was leaked…
    I think I have heard the Patapon theme at least 1000 times, if not more!

    I noticed in Revision 65+- you thank fanjita and noobz. Did they help with the HBL or was that just due to the eloader concept? I remeber the GTA LCS eloader fondly. That was my introduction to homebrew, and since I saw the “dark side”(or “light side” depending on how you look at it) I have never looked back. Do you think something like DevHook again?

    Keep up the great work and I am really looking forward to Wagic 0.12 on my Go!

  23. Banshee says:

    Thanks for the great help! I’m going to make more videos for n00bs who don’t know what they are doing lmao

    Regards,
    Banshee

  24. wololo says:

    @serpistica: you have an old save file. Download the new one from this page and stop spamming every forum/blog related to HBL.

    @Dillenger: Fanjita kindly contacted me and sent me the sources of the N00bz eLoader. Some of the code of the HBL comes directly from the n00bz eLoader.
    It was easier back in these days, because there was no syscall randomization, so we cannot entirely reuse the noobz eLoader, just a few concepts. The HBL would have been 100% complete a long time ago if syscall radomization wasn’t in the way 🙁

    The GTA:LCS eLoader was also my introduction to homebrew, the N00bz era is full of great memories for me 🙂

    I’ve played Doom with hbl, but then I’ve got a lot of errors!

  26. Peppe 46 says:

    when arrive the iso-loader???

  27. Muffinhead says:

    *smacks Peppe 46 REALLY hard across the room!*

    ………..*now kicks him.*

  28. sda says:

    IT DON’T WORK! WOLOLO, YOU MUST TEST ON ALL TYPES OF PSP’S UNTIL YOU RELEASE A HBL!!!! POOR, VERY POOR!

  29. wololo says:

    @sda: This revision has been tested on a Phat and on a PSPGo, so before insulting my work, make sure you have all the correct files AND if you still have a problem submit a proper bug report (dbglog + what you see on the screen)
    Also if you want me to test on all types of psp, please don’t hesitate to offer me the same model as yours so that I can complete my collection. I’m accepting money donations as well.

  30. Johnny says:

    Well T.O.M.E works on my PSP3000 at 6.20 😉
    However i can’t seem to get Wagic to work, sticks on Lopping HBL Treads.

    Johnny

  31. Elidson says:

  32. Bighead says:

  33. RedCloud says:

    geez, posted on the wrong page last time :/ You should post r70 (although im not demanding it lol), this one is missing a file. I know its not a huge update or anything but its still important

  34. wololo says:

    RedCloud, revisions 69 and 70 are identical, the file that was missing is just important for compiling on linux

  35. boygeorge says:
