VHBL for Monster Hunter

What is it?

Vita Half-Byte Loader is a homebrew loader for the Playstation Vita. It runs on the PSP emulator embedded on the Vita.

This is the official VHBL download page for people who own a copy of one of the following PSP Games: Monster Hunter Freedom Unite (US/EU), Monster hunter Portable 2ndG (JP), Monster hunter Freedom 2 (EU), and Monster Hunter Portalble 3rd (JP). If you don’t own one of these games, go back to the VHBL page to see if we have a version of VHBL working with a game you own.

This version of VHBL is compatible with firmware 1.80 and below. If you try to run this on Firmwares above 1.80, it will most likely fail.

Check the VHBL page for more details on this tool.

How to Install and Run HBL on Monster hunter Freedom Unite

  • It is *strongly* recommended that you turn of all wireless connections on your PS Vita, and that you use OpenCMA on your PC instead of the regular CMA. This is recommended because otherwise your console has a way to force you to upgrade the firmware even before you get a chance to use the exploit.
  • Extract the HBL archive matching your version of the game in your CMA PSP Savedata folder. It is a folder on your PC named PSSAVEDATA/[lots of random characters here]. If you don’t know where it is, check your settings in CMA
  • Connect your PS Vita to the PC through the CMA, it should give you the possibility to copy the savedata from your PC to the Vita. If not, you probably extracted it in the wrong folder. (Note: You will also want to install some homebrews with a similar technique, read the section below)
  • To run HBL, start the game, and the savegame should load automatically. Once you reach the main menu, click on “Download” and select “yes” to whatever question is being asked. At this point, VHBL should start. See the video below for a more “visual” explanation

How to Install and Run Homebrews

Installing homebrews on the PSP was an easy task. On the Vita, until better solutions are provided, it’s quite a pain in the ***.
The CMA will only let you copy savedata, and will not recursively browse folders.

To address this, HBL comes with a tool that can extract archives with a specific structure.

Packaging the homebrew for installation on the Vita:
1) download PSP homebrews from your favorite website
2) extract the homebrew somewhere on your hard drive, and with your favorite utility, zip it again with the store setting (no compression), in a file that you will name “INSTALL.ZIP” (uppercase is important). If your compression tool does not have compression options, I recommend 7zip.
3) take any PSP savedata (but not the one used for HBL!), and add the “INSTALL.ZIP” to that folder, in your PC CMA folder. so your PSP Savedata will look something like this:
in folder PSSAVEDATA/1a2b3c4def5678/UCUS12345000/ (or something like this) you will have the following files:
– ICON0.png
– PIC1.png
– DATA.bin

On this page you will find several pre-packaged homebrews that have already been prepared to run with VHBL.

1) run OpenCMA on your PC, and CMA on your Vita
2) copy the previously packaged SAVEDATA (see above) with your homebrew in “INSTALL.ZIP” on your Vita
3) run HBL (how to run HBL is explained in the previous section)
4) navigate with the HBL menu to the SAVEDATA folder, then go to the folder you just downloaded (in my example, UCUS12345000), and click cross or circle on it
5) At this point, the HBL menu should ask you if you want to install the homebrew. select yes, and wait until HBL is done extracting your homebrew
6) The homebrew is now installed, and you can run it by going to the GAME folder, if everything went well, a new subfolder with your homebrew has been created here, and you can run the homebrew

OpenCMA is strongly recommended to install if you want to use VHBL. Open CMA is a tool by Virtuous Flame that allows you to copy files from and to your vita without being connected to the internet. This is useful, especially if you don’t want Sony to forcefully update your firmware.

  13. kyleeee says:

    thanks i almost have this working but when i go to install the snes emu in vhbl it freezes up makes a clicking noise and says 6 files remaining. what could this be and how ling does it normally take to install, thanks again!

  14. MrPotaDos says:

    After a long time of play VHBL just freezes on me.Anyone else getting this problem too?

    • trey says:

      I had this problem too. After a while the audio starts going from good to bad and back, until the whole thing freezes all together and says an error has occurred.

  15. Cyan says:

    I still see MH in the PS store. I assume if I see it Sony must not have done anything to it yet right? How long does it take them to patch it? Can they “stealth” patch these games?

  16. Kylar says:

    Just confirming for anyone not sure,

    Monster Hunter Freedom 2 Essentials DOES WORK. It is also still available on the AUS PS store. You must use the VHBL R160 for Monster Hunter Freedom 2 (EU).

  17. trey says:

    Hi Wololo, I’ve been using your 1.8 VHBL since day one and have all my favorite PSP homebrews on it…but there is this one game(OpenTyrianpsp1.0) that has very buggy sound. On the PSP it’s audio does the same, but only rarely for less than a second each time. I’ve recently found the VHBL homebrew preparer that is supposed to make the homebrews more compatible, but I guess it doesn’t really. It only helps it to run without freezing. If there is anything that can be done can you please tell me.

  18. Hien says:

    I live in the USA, and I successfully got the VHBL hack to work. As of 9/17/2012, the Monster Hunter Unite game is still in the PSN store and everything seems to work perfectly.

  19. unbornchicken says:

    Hi there, I posted this in other topic, but hopefully here it will be seen sooner. I got to load VHBL from MH but it does not show the PSP save files for any emulator (not even the folder), after successfully (supposedly) copy them with CMA. Im sure is not a problem of compression of the INSTALL.ZIP because it doesn’t even recognize the Wololo Wagic premade save file. Any idea?

  20. oreo says:

    Is this patched in 1.8.1? I’m about to buy monster hunter if it’s not patched. Thanks Wololo for another amazing exploit. 😉 happy someone likes to stick with their work and not abandon it.

  21. Ram says:

    has the game monster hunter freedom unite been patched yet cause i bought it today 9/22 before knowing if it had been patched yet can someone confirm if im still good

  22. ivo says:


    how do i put a .pkg i bought on my ps vita …
    bought it with media go
    should work on a psp or ps vita but no clue how.

    i thought of content manager but it forces me to update
    even opencma doesnt bypass the update feature these days ..

    the ps vita is still on ps vita firm 1.67 but howlong beats me
    becuz i cant put any content on it imho.
    it always asks about a forced update when i usb or wifi or 3g.

    so pretty useless device in my eyes.

  23. ivo says:

    howfar could one reverse a vita or a psp once its cracked ?
    my experience so far with hbl and vhbl its

  24. gjanko2 says:
