As it was announced some days before, a vulnerability disclosure has been found on the game: Gamocracy One: Legend of Robot which makes your PSP/PS Vita at risk of running malicious software such as Homebrews,Emulators, etc. The game now has been pulled off from PSN and only its owners on 2.12 or lower can use this exploit! Below is a guide which will help you install it in your Vita and also a small guide which will teach you how to transfer homebrews![EXPLOIT INSTALLATION GUIDE!]
Step 1 | WHAT YOU NEED?
1)A PS Vita on Firmware 2.12 or lower with Gamocracy One: Legend of Robot already installed in it!
2)HBL Archive(Edited savedata) | Download EU US.
3)138Menu (Is suggested for better configuration) | Download here
4)OpenCMA for 2.1X or higher | Download here!
Step 2 | INSTALLATION
-Download it, extract the archive in your CMA folder (program files/Sony/Content Manager Assistant by default)
- quit the CMA if it is running on your PC (Or stop the task from WIN Task Manager)
- execute "run.bat" (you need to run it in "Admin mode" on windows 7)
- That's it, now the CMA should run without requiring to be connected to the internet!
2)Install the exploit:
-Download and 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!
-Download 138Menu and copy EBOOT.PBP, DATA.138, LTN9.PGF and 138CFG.TXT into the HBL's folder inside the CMA savedata folder.
-In the end, 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)
-Installation is DONE!
Step 3 | LAUNCH THE EXPLOIT
Go to your PS Vita's menu, find Gamocracy's bubble and run the game. When its done loading, go to HIGHSCORES and it will "crash"/transfer you to 138Menu automatically.CONTROLS OF 138Menu
While in main menu:
DPAD/Rtrigger/Ltrigger: Roll circle (Change category)
CROSS: Enter submenu
While in sub-menu:
Rtrigger/Ltrigger: Roll circle (Change category)
CIRCLE: Go back
Now you are done! The exploit is successfully installed into your PS Vita!
---------------------------------------------------------------------[GAME/HOMEBREWS INSTALLATION GUIDE]
for 138MenuHOMEBREW FILES
Homebrew names compatible by default are wmenu.bin, VBOOT.PBP and FBOOT.PBP. You can also configure a custom name, check the config file part. The menu will automatically search in ms0:/PSP/GAME/ (for 2.10-) and the path specified in the config file. EBOOT.PBP's will be automatically converted to the specified custom name!
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).
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/ you will have the following files:
Now transfer the savedata into your PS Vita using Open CMA,run the exploit and when 138Menu loads, navigate the savedata you put the INSTALL.ZIP in and press X to install it!
Done! You have successfully installed your first homebrew!
* IMPORTANT: About the installer deleting method, it will delete completely the installer folder; if you put a INSTALL.ZIP file in your exploit folder it will be detected and the menu will only delete the INSTALL.ZIP file, leaving the rest of the files safe.
* CONFIG FILE
Needed by the menu, if it doesn’t exist or is corrupt then a default config will be generated, read INFO-138.txt to get more info
* CUSTOM BACKGROUND
If you wish to use your own custom background, just put it in the menu folder and rename it to WALL.PNG, if no custom background is found then the default background will be loaded.
