    *disclaimer* thats the only logical reason i could think of, there may be something im overlooking, but i cant see any other reason to just give every game a signed ticket to run the eshop version on any system......but then if that really was the case and it was just remnants of a scrapped feature, then why did they continue to make valid tickets for every game, if the feature was scrapped surely they could have just thrown in dummy tickets to fill the gap, or just removed them entirely

    ahhh, nintendo logic :wacko:

    They don't seem to be used for installing, i think it is for some required sign checking on cafe2wii/wii mode.
    Maybe they just kept the minimum necessary fields to avoid having to use retail signing tools on a production environment?

    I remember in the Wii era that tickets do in fact install in the console, when I used AnyTitleDeleter I see A LOT of tickets of various virtual console and wiiware titles that I deleted long ago still there.

    If you mean 3DS gamecards, I think that 3DS gamecards don"t use tickets.

    I don't know, we can't install Wii games on the original Wii. If we are modding tiks of disc based games for the system to see then as eshop downloads, there must be some tiks storage like the wads did in the Wii era...or the systems are completely different and the tiks only exist for signature check and nothing is stored in the sysNand at all?

    Wii disc games have ticket too.
    that's what allowed the user to copy the savegame to the console. without inserting the disc (just inserting, even without launching it) you couldn't copy a savegame for that game.
    or maybe I'm mistaking with another file where all played games are stored. but disc have tickets.

    If the tickets are bad when extracting the wud with current extractors, then it means the tickets are not installed as "eshop" games, but as disc games using the proper (fixed) ticket that the disc contains.
    editing the ticket is actually fixing it, not modifying it to make the console accept it as an eshop game.

    if you already played that game disc, the ticket is already on your console. but to install the game into the console you still need that ticket to validate the decryption of the encrypted files from nus.

    the point is that the disks have the ticket for the full eshop game despite disks not using that decryption key and there being no real reason for them to be there, tbh i always wondered why they were there before this little revelation, its funny that a bug in the disk dumping tool left everyone unaware of this for months.....i wonder if it was intentional :ph34r:.....either way, i guess all those scene releases now ought to be nuked :P *kaboom*.....oh actually was it just a bug in the wud extracting tools....ok nevemind me thats more likely i guess XD

    EDIT:- ok yeah it was the extracting that was done wrong....carry on, nothing to see here :P

    but still, i read something that we mere public scene mortals can't get wud keys, we only have wud keys from the scene releases?
    that's true? as i have said before i'm new to wiiu and i want to understand as much of it as i do the 3ds. :D thanks

    So I have Mario 3D World on disc, played it months ago, and when I started the game for the first time the tik are installed in the system as a "disc tik". Then, I installed 3D World on the system to have a digital backup (no more disc changes, yay), in this case nothing changed in the system at all because I already have tiks for 3D World inserted because of the disc. In another case, I installed Mario Party 10 too, but never inserted it the disc on it, so for the system it's like I inserted one because of the disk tiks stored for the game.

    Thank you for the clarification and sorry for possible bad english (I don't write in this language too often).

    yes, the WiiU dump need a disc key to decrypt it. they are usually provided with the dump (in the nfo, or in a binary file)
    I don't know how this key is retrieved.

    not enough in my taste.
    I'm not studying, just remembering what I read. But not learning more than I need. (I would need more time)

    So I looked into it and this what happened and how to do it right.

    For all the parts you use the content ID as the IV over the 2nd byte, which all tools do here so you get 0x03.

    Apparently for the "system" partition the block count is used on the 16th byte. Block size is 0x10000.

    title.cert is always at offset 0 so the IV is all zero.
    title.tik is always at offset 0x20000 because title.cert is fixed in size. so the IV is 0x00000000000000000000000000000002
    title.tmd is always at offset 0x100000 because title.tik is also fixed in size. IV: 0x00000000000000000000000000000010

    A new DiscU version with this fix and a content extractor is currently in testing.
    So if you have the WUD lying around you don't have to download it from NUS.

    No, that's not the case. I have a Wii U which came with Mario Kart 8 preinstalled. The console has never been connected with a NNID though the console ID at 0x1D8 isn't nulled.
