NEW FEATURE

Follow up of #18555 and #18575 extending integrity check:

  • Add multi-package (selecting multiple files) integrity check on context menu for:

    • PSN Content (.pkg, .rap, .edat)
    • PSN DLC (.pkg, .rap, .edat)
    • PSN Game Update (.pkg)

    NOTE: For .pkg file, the file type and so the related target DB (e.g. PSN Content, PSN DLC or PSN Update) is auto-detected parsing the file. File type for .rap and .edat files cannot be detected parsing the file. So, we instead check on PSN Content DB first and if no match is found then check on PSN DLC DB as fallback DB

  • Add integrity DB download on context menu

  • Add support to integrity check also to BD drive

NOTE FOR MAIN DEVELOPERS



closes #18575

Needs APIs to be implemented before merge

How does this work exactly? I must be missing something here. The no-intro data contains hashes for the packages and licence files. The emulator only has installed games, not package files (installers). How can you verify the integrity of an installed game like that?

Installed data cannot be verified even for ISO or JB format.
Currently you need to select and check the .pkg and .rap one by one. The same for DLC and game update. I was thinking to allow multiple selection (e.g. to select all the update files) in another PR. Just to make this PR light

It looks like it just pops up a menu asking the user to select the PKG file they want to verify - it doesn't seem to be connected in any way to the entry that was selected in the game list (as expected I guess, because there isn't any link between the installed game and the installer for digital titles):

I think this feature would be better placed if offered on the Install Packages screen (verify before install or something?) and/or available from the Utilities dropdown menu rather than the game list.

Indeed, if it's for pkg installer validation, it should not be on the game list context menu, otherwise it's misleading, makes it seem like an integrity check of the installed game

I provided Check Package Integrity under a unique context submenu Check Integrity. Here you will find the ISO check, the JB check (when I'll do that) and this general package check. I think that a unique container in the most used menu (context menu) is overall the best place. IMO, moving this feature on another menu will remain an hidden feature for the majority of users. There are also other non contextual features on the context menu (e.g. a general compatibility DB download, config DB download and integrity DB download

Added fallback DB for .rap and .edat. PSN Content DB is used first and if no match is found then PSN DLC DB is used.
Added support to multi pkg / rap / edat selection.
Added also support to integrity check for BD drive.
From my side, the PR is complete
