90w ago - Following up on his previous release, today PlayStation Vita developer PsDev has made available a Multi PKG Tool which now allows users to decrypt and extract PS3, PSP, and PS Vita PKG files.
To quote: This is a new software to convert a PARAM.HIP file to a PARAM.HIS (HIS are used by the PS3 as a change-log file).
It can be viewed by going Game -> Triangle -> Update History
This file needs to be located in the same folder as the PARAM.SFO ( /dev_hdd0/game/TITLE_ID/PARAM.HIS ).
Finally, from ps3devwiki.com/wiki/PARAM.HIP:
This file is used to display the changelog texts of a HDD game (category HG), game patches (category GD with APP_VER), and gamedata (category GD without APP_VER). Texts are displayed under the option "Update History" when pressing triangle over his icon.
PARAM.HIP files are the "source" file, contained in the root of a Install_Package.pkg. When the package is installed the system adds at the beggining of the "source" file 10 bytes containing his timestamp (date and time when is installed), and copyes it in the install folder as PARAM.HIS.
PARAM.HIS files can be updated by consecutive installations of more .HIP files over...
1. Custom Coldboot
2. Kiosk/Shop XMB restrictions have been removed so PlayStation Home/PlayStation Store work fine.
3. Modified to allow installation of retail signed packages
Notes: DO NOT install this unless you have an E3 flasher or Progskeet type device to downgrade your PS3 to 3.55. Unfortunately 3.55 signed PS3 homebrew does not install/run. Also be aware it doesn't load any PlayStation 3 game backups so you will need to have the game disc to play them.
99w ago - Below is a video demonstrating my PS3 4.00 Dev_Flash modification, which simply allows users to install Retail signed package (PKG) files from the PlayStation 3 XMB.
Note: This modification does not allow the installation / usage of unsigned content / PS3 homebrew etc. This is purely a convenience hack and is aimed for use by those who have hardware flashers which allow dual boot.
After technodon's work creating a modified kiosk dev_flash which lets you install retail signed package files. The restrictions of having to use kiosk firmware inspired me to find a way to add "Install Package Files" for retail firmware.
This is hack does the following things:
adds "★ Install Package Files" and "★ /app_home/PS3_GAME/" to "GAME" on the XMB (allowing the user to install retail package files anytime they want)
adds other debug functions which are small but still there
does not give access to "★ Debug Setting" (reasons for this are explained below)
This installation procedure is the similar to technodon's original dev_flash hdd swap procedure
