Thread: Scrubbed games

  1. #1

    Scrubbed games

    I've seen a few questions about them pop up here and there, mostly people wanting to know what it is. Well this is a different question

    1. How can I tell whether a game has been srubbed? If I'd know where to look, I could open the ISO in winhex and search for a lot of 0xFFs but perhaps there is a easier way.
    2. Can I unscrub a game? I.E. is there a way to restore the garbage data? I've found this option in Wii scrubber but do not really know how to use it.
    3. If Nintendo were to check for scrubbed games, I assume modchip creators will be able to circumvent the checks?


    cheers,

    1. When you download the game it should say "scrubbed" in the title. If not, the game will be exactly 4.37 GB (4,699,979,776 bytes). If it is less, it is scrubbed.

    2. I saw somewhere that you could, but it will work even if it's scrubbed.

    3. Nintendo can't detect if you're using a backup games or a modchip.

    When the game is extracted from the RAR they are all 4,699,979,776 bytes. Unfortunately, I keep the games unrarred so I can't tell whether the download size was significantly smaller than approx. 4.3 gigabytes.

    I'm just a little concerned nintendo will update its firmware and check for large sectors of 0xFFs. Assuming nintendo will check for that, it would be enough to refill these sectors with random data. Of course it will not be the original garbage data but it should do. When hashes come in to play there's a much bigger issue though.

    A that would be a firmware update, so dont update :P
    B out of anything, why would they waste their time, preventing them from playing ALL, not some :P, and that wouldnt even make a huge difference

    just dont worry about it, and enjoy

    well, usually scrubbed games are trucha signed in some way so nintendo did do an update (3.3 and up) that prevents these games from being played directly, you now need to use Gecko OS to load them (unless you stay on 3.2) or some other loader

    NDS lite + R4

    In order to unscrub an image, whoever scrubbed the image in the first place must have selected the "DIFF" option in WiiScrubber and include that data with the scrubbed ISO file. I believe that is the only way to unscrub an image, because that data tells WiiScrubber how to rebuild the ISO file to its original format. It generally ends up being a few hundred MB for each ISO file, or so I read, so if you're archiving the ISO files, it's still smaller in size to archive the scrubbed ISO and the DIFF data, but in the long run keeping the DIFF data adds up to a lot of space once you have a lot of ISO files archived. I personally think uploaded scrubbed ISO files should always include the DIFF data so people who have firmware 3.3 or later will be able to play the games, but for the most part the DIFF data is not included to keep the file size as small as possible. I'm staying on 3.2 firmware for the time being, and this is one of the main reasons why. There's really no downfall to staying on 3.2 though, since as long as you remove the update partition with Wii Iso Utilities or any brick blocker the games will not prompt you to update your console before you play the game (for games that 'require' a higher firmware version).
    Hail to the king, baby!

    Hi. I have a scrubbed ISO file, but I don't have the DIFF file.
    I downloaded the WiiScrubber 1.3. But can I unscrub the image without the DIFF file?? I tried, but it keeps asking me the DIFF file.

    Please help!!

    Thanks.
    Best regards.

    You do not need wiiscrubber to extract a scrubbed file, it will extract to the right size iso (4.7Gb) when you unrar or unzip it

    Here's how I do it....... others may have different ways, so pick the one that suits you.
    Programs used

    Utorrent...... to download
    WinRar........ to extract ( also does zip files too )
    Nero 7........to burn the disk ( Nero Burning Rom )

    Method

    I created a file on my desktop and labelled it torrents........ this is my default download file for utorrent to put the downloaded rar in to.

    I created a file in My Documents and called it Wii Games.

    When the torrent has completed downloading, I open the torrent folder and "right click' on the rar file, I "extract files" to the target folder "Wii Games" which extracts it to an ISO file (4.7Gb)

    I double click on the ISO file which start Nero 7 "burning ROM" - I adjust the settings to force burning at 4x and click "start"
    I put in a "good quality" disk and do not do anything on the PC until the burn has finished ( converting & burning games / dvd's is memory intensive )

    The only "coasters" I have had have been down to poor quality media although the disks are good for burning dvd movies the Wii does not like them

    before burning the scrubbed image, what's the use of the iso patcher or ios patcher?

    In very simple terms........ that I understand

    Back up launchers reference ios249......... therefore you patch the game with 249 to get it to play ( in the old days, every iso had to be patched, but Gamma .03 does magic inside the wii and gets it to work as 249 ). There are a couple of exceptions ...HOD 2&3 needs patching to 249 and Medal of Honour -Heroes 2 are mine that had to be patched

    Modchip users will patch to ios30 for the same reasons
    Have you used the search function ? used the Tutorial section ?

    Did you know you can donate to help the running of this forum ?

    hi...sorry we're busy, so only giving priority to supporting members like MK contestants / forum donators at this time...


    The advice given is up to you whether to act on it or not. NO responsibility is taken for you screwing up !
    Thanks for your understanding
