VHBL for Gamocracy One: Legend of Robot

What is it?

Vita Half-Byte Loader is a homebrew loader for the Playstation Vita, running through the PSP emulator on the Playstation Vita.

This is the official VHBL download page for people who own a copy of the PSP Game Gamocracy One: Legend of Robot, and a firmware 2.12 or lower. If you don’t own this game, or have a higher firmware, go back to the VHBL page to see if we have a version of VHBL working with a game you own.

Check the VHBL page for more details on this tool.

Known issues

Not all homebrews will work with VHBL, head over to the gigantic VHBL Homebrew thread for details on what games work or not.

There is a bug with the default menu (wMenu) which might tell you with a red screen, something along the lines of:”Error! Couldn’t find any homebrews in ms0:/PSP/VHBL/ Please check your config file and/or restart VHBL”

If you see this error, don't freak out, just press LEFT TRIGGER

If you see this error, don’t freak out, just press LEFT TRIGGER

This is a known issue, and happens only as long as you don’t have any homebrew installed. To get rid of this error message, press the LEFT TRIGGER on your console, this will force wMenu to go to the SAVEDATA subfolder.

The issue is a simple one but I was too lazy to fix that. People with the right coding skills might want to have a look at the source of wMenu here and send me a patch.

alternatively, you can give a try to an other menu such as 138Menu here

How to Install and Run HBL on Gamocracy One: Legend of Robot

  • 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, then go to “High Scores”. At this point, VHBL should start

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:

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 VHBL 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.

    It keeps Saying: Freeing Memory… How to fix ?

  2. Omar

    When VHBL boots it says freezing memory and VHBL fails to load, any help?

  3. andrea

    same here D:

  4. Soosthemoos

    Odd. VHBL has booted, and I can navigate to the NPUG80413SAVEDATA folder for Piyatoma that I converted into the prepackaged Lamecraft r56, but it won’t install or display the INSTALL.ZIP that I know is there. I tried again with JellyCar V1.1, but the same thing. Anyone know what the problem might be?

    TL;DR, VHBL not trying to install homebrews. Help?

    • Soosthemoos

      Never mind me. I should have paid more attention to the word “prepackaged.”

      TL;DR, I’m an idiot.

  5. mikey

    The EU version stops at “Freeing memory”, but its still possible to leave the VHBL using the PS-Button.

  6. PeffHD

    When I copy it to my device, it doesn’t show on home screen. PLEASE SOMEONE MAKE A VIDEO ON IT! PLEASEEEEEEE

  7. SakkeMO

    Eu version working nice thank you.

  8. PeffHD

    When I install it on my psvita, the app is not on my home screen. Can anyone make a voice tutorial on youtube and put a link on here? So please.

    • SakkeMO

      You have to launch the Legend of Robot and go to highscores to launch vhbl

    • shay

      its not suppose to go on your home screen, did you even read how to install it? you get to the VHBL going into the Highscores in the game…

    This thing makes no sense. Installing homebrew just doesn’t make sense at all. The directions aren’t clear enough, or my comprehension of it is terrible, but either way, it needs a more detailed walk through.

    • Chen5441

      There has been a tutorial made by thez94
      On YouTube. Stop complaint and actually look and maybe you would’ve found it yourself.

    • wololo

      Just download pre-packaged ones initially from our forum. You’ll get the idea with time. Other people have figured it out, you’ll understand too eventually. The technique is cumbersome and my explanations are not great, but it’s midnight here and I have to wake up early for work tomorrow. The community is better than me at explaining stuff 🙂

    • Chen5441

      Are you serious… There has been a tutorial of how to install it since before the actual files were released. The guys name on YouTube is “TheZ94”

    • Josh

      I have a similar issue while trying to install the Snes and nes emulator. Im guessing i must have messed up somewhere. Any advice?

  15. Shise

    hi after homebrew installation do we need to keep the psp save file?

  16. MrAyzarC

    hy, i have installed the VHBL with the eur exploit.
    ive already installed a few homebrews but everytime i try to launch them i get thrown out of the game.

  17. Spyrowon

    I did everything correctly but whenever I go to content manager on my Vita, It doesn’t show up in the saved data, (PC -> PS VITA SYSTEM, SAVED DATA PSP/Other) I did everything Thez94 did in his tutorial. I’m on 2.12 and U.S. Version of Gamocracy.

  18. RokieFelt

    It works perfect! / /
    For those who have not yet been able to make the simple form.

    -Keep the “Savegame” of some other game they have. on your computer to add the “install.zip” folder in “/ PSAVEDATA \ NUMBER \ SUSAVEDELJUEGO \ (which is uncompressed, and ready the discharge section wololo).

    -Remember the name that will appear the same in the VHBL.
    -The visit VHBL folder “savegame” thus kept show all the other games, the lodge is that clicking on the savegame that has the “install” will recognize and install. posteenlo doubt here and try to answer salu2

  19. Sparkey

    I use the prepackaged files, and follow instructions as best I can, but I’m running into a problem.

    When I select the save file in the HBL that contains the Homebrew, instead of asking to install it I just go right into the folder, still in the directory.
    What am I doing wrong?

  20. tonny

    managed to install drive but I can not put roms.
    I’m sorry but it’s the first time I VHBL
