91w 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.
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
• Installing of MinGW, msys, msysDTK and setting the environment for msys
• View PKG info
• View PKG Contents
• Unpack PKG
• Decrypt EBOOT.BIN
• Edit .ELF
• Encrypt .ELF
• Edit SFO
• Generate PKG config file
• Repack PKG
It's a command line tool and will automate some task and make the job of pkg modifying and generating a much easier. It's not perfect and I'm not a coder but when I have time and you guys like it I will update the tool.
Just unpack the .rar to .exe and install it where you want.
