    So well, the new PKG Installer 2.0 has just been released, but in spite of its name, it doesn't install PKG files, and rather installs PKGS files. I'm not a dev guy, so what's the difference between them actually? I was told by Silica (the creator) that I can only install a PKG file if I know "how to extract it". Is that already possible? I do have some software that I would love to install, in form of PKG files, from the old PKG files list.

    Thanks in advance to anyone that can enlighten me.

    PKG: are for things like dev apps that requires decryption, kernel access, and the ability to turn a retail vita into a dev unit.

    PKGS: is only for game demos, full games, themes, and dlc. Which all requires decryption, but I don't know if kernel access is still required.


    Edit: we can already take some dev tools/apps and put theme on our retail ps vita's, the problem is in order to run those dev tools/apps we would need kernel access along with the ability to turn retail vita's into dev units.

    Is that the case? Because I've been downloading demos identical to the ones that are .pkgs format in .pkg.
    They're honestly the same exact files aside from the file extension (and evidently encryption). Even the file sizes are identical.

    Edit: I lied. The "Colors [Demo] [US]" PKGS file is 10.0 mb, whereas the PKG file is 10.8 mb.

    PKGS is basically a non-compressed ZIP/7Z file.
    PKG is encapsulated with encryption. That's why you'll need the AES key to extract it.

    I see little reason to run this now that you can use VitaRW to replace the Package Installer with the Dex version.

    Unfortunately if people want to install pkgs they will need to install the app created by silica.

    Why would anybody need to install .pkgs when .pkg installation is now possible?

    Because those are two different formats?

    Not really, A pkgs is an extracted pkg, similar to a vpk.

    If a pkgs exists of anything, a pkg exists also.
