22w ago - Recently French PlayStation Vita developer NtRnOs shared a Proof of Concept (PoC) video demo on installing PKG games and applications on the PS Vita handheld console.

Below are the details, roughly translated:

This proof is not a hack but just to show how to install PKG PSVita outside the circle with the usual and customary and PSN content manager "PSViTA/PS3/PC"

• Download your PKG then copy it to a storage system external or internal to the PS3.
  
• Install it on your PS3 via "install package" (this may take a few minutes).
  
• Find it in the queue (TASK) files to install the PS3 (PSVita download content via PS3 or transferred PKG PSVita will not install on your PS3, they just put in the queue waiting to be transferred to a system PSVita).
  
• Connect your PSVita to your PS3 and go to the content manager (PSVita)
  
• On your PS3, you should find your PKG copied earlier in the queue for the PS3, click to install it (the PS3 will ask you to connect the PSVita for the transfer).
  
• In the content manager of PSVita select PS3 PSVita transfer and application, and the ones you want to transfer.
  
• To finish the PS3 delete the file from your system and you find the application / game installed on your PSVita.
  
• PS3 PKG checks PSVita...

61w 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.

Download: Multi PKG Tool v.1.0.0.1

To quote: This Tool can decrypt and extract Playstation Vita, Playstation Portable or Playstation 3 retail pkg.

It uses the PSP/PS3 AES key that is used to decrypt and extract PSP/PS3 retail pkg. However, No longer can Playstation Vita PKG over beta/retail 1.00+ be decrypted and extracted with the PSP AES key.

AES Keys used
I would like to give a big, big, big thanks to Mathieulh, Because I used his AES Engine to decrypt PS3 retail pkg, Without that it could have taken me way longer to make this tool.

61w ago - Following up on the PS Vita .PKG xTractor 1.00 Homebrew App previously released by SKFU, today PlayStation Vita homebrew developer PsDev has made available a PSVita PKG Tool v1.0 that can also be used to decrypt and extract PS Vita PKG files.

Download: PSVita PKG Tool v1.0

To quote: One day I was going to decrypt and extract the 1.00 Ridge Racer PKG. I went to download SKFU PKG xTractor and found out it was upload through MegaUpload. I look on the Internet to see if I could find any other sources where this could be uploaded to and was not successful at finding it.

So I made this, it was for personal use, but... Why waste time when I could release this for other people that don't have his tool and want to do the same thing? So here it is.

This little tool can decrypt and extract PsVita beta/retail pkg under 1.00. it uses the PSP AES key used to decrypt and extract PSP retail PKG
No longer can pkg...

77w ago - Following up on his recent PS Vita Firmware xTractor releases, today PlayStation Vita hacker SKFU has made available a PS Vita .PKG xTractor version 1.00 homebrew application for developers followed by v1.01.

Download: PS Vita .PKG xTractor 1.00 / PS Vita .PKG xTractor 1.00 (Mirror) / PS Vita .PKG xTractor 1.01 / PS Vita .PKG xTractor 1.01 (Mirror)

From his page: After two sleepless nights and great help of iQD and PS3-690, finally the PS VITA .pkg xTractor application 1.00 is finished. This program can decrypt & extract PS VITA game package (.pkg) files.

To use the program you need to place the PS VITA .pkg AES key in the same dir as the executable. Funny as SONY is, they probably were to lazy to think of a new key and just used *hehe*, the PSP .pkg AES key.

Information tab not finished, yet. It will be completed in next version. So just put the PSP .pkg AES key in hex syntax in aes.key file in the same folder and you are ready to...
