  1. I’m trying to split .wbfs files larger than 4GB, and load them onto a fat32 file system. Whenever I choose the 4GB option in Witgui, I find that the first file is split to 4.36GB (approx). This files size is just small enough to be successfully loaded onto a fat32 file system, but when I try to play the split file, the screen goes black and returns to my Wii system menu. However, if I choose the 1GB split option, the game will load fine on my Wii. This seems to be a flaw in the Witgui program, as 4GB split files should actually be of that size (or smaller). Is this behavior indeed a flaw, or is it intentional? Thank your this program and your support btw. Despite this one flaw, Witgui is an excellent solution for Mac users wanting to modify their WBFS files, and I will point Mac users in this direction whenever the issue arises.

    On a side note for any users experiencing this same problem; one can also partition a disk drive with one partition fat32 (for file sizes below 4GB), and another partition NTFS (for file sizes above 4GB), a setup which is working flawlessly for me so far.

    1. No, sorry, this format is currently not supported by the wit tool so it will not be supported by Witgui either.

  2. Hello,
    I am having some issue with a an iso game which can not launch on my WII.
    It is correctly listed in my WBFS partition (though it is only 268MB compared to the 4.7 GB of the iso version) but when I try to launch it is blocks at the very beginning.

    Do you think it is the game that is corrupted or does it come from my wii setup?

    Thanks in advance for your help

    1. I’m sorry but I cannot help with issues related to games not working on your Wii. You should contact the developers of the software you use to run them on the Wii. (WBFS partitions have storage optimization which is why the game is usually smaller than the iso file.)

  3. Hi
    Im using Witgui for several years and sometimes when i open it to upload new games into de WBFS partition it shows “0 WBFS partitions found”, but when it happens just update database, wit and wwt… So far it has worked well.
    Now its happening again but when i try to update wit and wwt a message shows “A server with the specified hostname could not be found”… so i can’t fix it.
    What do i do then?

    1. Please make sure you’re using the most recent update. Last year the server where those files are hosted was changed so the old versions still point to the wrong server.

  4. I have an external disk I already use with the wii with backups on. No problem. I plug it into my mac and can see directory structure and files. When I run WitGui though and click WBFS Partition button though the window that pops up says 0 WBFS partitions found.

    I don’t want to format it as I already use it ok on my Wii – any ideas what the problem might be.
    Im running MBP Mac OS Catalina

    1. It says 0 WBFS partitions because that’s not a WBFS partition. If you can see the directory structure in the Finder, then you have to click on Open Folder instead of Open WBFS Partition.

  5. In witgui in my macbook air , it doesn´t want to format my usb (fat 32) into wbfs, it says: it doesnt have permission or something like that

  6. Hi,

    First Thank you for your great GUI, I’ve used it for a few years but after upgrading to Catalina I’m having the following error:

    !! wit: ERROR #126 [FATAL ERROR] in wd_read_part() @ src/libwbfs/wiidisc.c#865

    I get this error as soon as I open my GameCube folder. Wii folder shows fine.

    This seems to be a problem with the WIT 3.02 version. So I tried installing 30.1 from ZSH but no luck so far.


    Anyway to fix this? Thank you in advance!

  7. Hi, I have been running into issue after issue with WitGui, all which I’ve been able to resolve except for this one. Once I open the folder containing my ISO’s, they show as expected with the artwork and the ISO/GC tag. The problem is – I cannot successfully drag them into the WitGUI window for my WBFS 1TB hd. I receive the error:
    “An error has occurred while adding X.iso to the WBFS partition Y. Please make sure that the source file is not corrupted and that the destination drive has enough free space.”

    This hd has 1TB free with nothing on it. The games are in ISO format, extracted using unarchiver from .7z.. I also am not able to verify any game. I receive this error message:
    “The game seems to be corrupted. !! wit: ERROR #30 [WRONG FILE TYPE] in SourceIteratorHelper() @ src/lib-sf.c#6052
    !! Wii ISO image expected: /Users/postlapsaria/Desktop/ROMs/GC/007 –
    !! Everything or Nothing (USA).iso
    ! wit: No valid source file found.

    Any help would be greatly appreciated.


  8. hello,
    how to use Witgui, I have the latest Mac OS Catarina and I download the Witgui file but when I click on folder or bfs partition I got the message wit file is not install. I don’t understand because any button to click for downloading or install.

  9. This program has worked great, I really enjoyed it. I made the mistake of moving to Catalina which has disabled all applications using 32-bit so I have not been able to use it since I moved to the new os. I know that your application has been around a long time, but if you ever made it a 64 bit version, that would be pretty amazing. If not, I’ll just find another computer that is on Mojave so I can still use your app. Great work!

  10. I have tried to read Wii and GameCube discs on both my MacBook Pro and my MacMini Server. I have used both their built in optical drives as well as external USB DVD and BluRay drives. The MacBook automatically ejects the discs, you don’t get the option to do anything. The MacMini asks you to EJECT or IGNORE. Either way, you still can “see” the disc. WitGui doesn’t get the chance to SEE the discs either.

    The program RUNS fine on a Mac, but if it can’t read the discs, then what’s the point?

  11. Hi, first of all I love the application Witgui, I used it for a couple of days!

    But since I used the “update database” option it crashes as soon I open it.
    I removed and reinstalled, restarted the iMac, but nothing works anymore 🙁

    Please help!

    1. There seems to be a new game in the database without an ID which causes the crash. In the meantime (before the upcoming update), you can manually delete the database located at “/Users/yourusername/Library/Application Support/Witgui/wiitdb.xml”.

  12. Just wanted to thank you for a great application managing the wii and gamecube library on the Mac. Keep up the good work! 🙂

  13. When adding several games I find that the progress bar on the app icon in the dock/switcher goes way past 100%. Maybe some sort of rounding error?

  14. Hi, I deleted all my 79 games and chose verify. Then I went out for the afternoon. When I cam back, I was greeted with the message “this game seems corrupt” (can’t remember the exact words) but it did not tell me which game out of the 79 games. It would be great if there could be a column in the user interface that displayed the status of each game (tick for verified, cross for corrupt/unverified). Thanks! Really nice app.

  15. Hi,

    I am using OS X Yosemite and I can’t mount any partition from witgui.
    My key is properly connected and formatted in FAT32.

    I tried the CHMOD thing and also answered Yes in witgui to give admin access to wwt, but without any success. Witgui always displays 0 disk(s)/partition(s).
    I also tried to start witgui from the command line to see any error or exception, but can’t find any. The only text displayed in the console seems to be some output from wwt itself about program version.

    Any chance my OS version could be the root cause of this issue? If so, will be really sad as I can’t upgrade because too many licenses to buy again 🙁
    Tell me if I can give a hand in any way to fix this.

    Thanks for your work 🙂

  16. Hi and thanks for your efforts!
    Got this issue: version 2.2.8 on High Sierra, USB disk 500GB. I erased the partition as you suggest (Mac OS Extended – journaled), then I used Witgui to format WBFS. All well, the destination window gets shown. In the source window I list the games I have in a folder (they’re in subfolders and are already .wbfs files). When I drag-n-drop them, nothing happens.
    What am I doing wrong?

  17. Cant format partition says drive couldn’t be unmounted, then says formatting but nothing happens. It works if I format the whole drive though Any fix ?

  18. So it seems in the latest version of witgui and latest osx I cannot actually drag games out of the witgui window when using wigui as the source window… shame because I used this extensively before.

    Also noticed that the app doesn’t populate the window with games on initial folder selection, requires pressing the refresh button first.

    Also noticed choosing a folder, closing it, and choosing the same folder again doesn’t bring up the window anymore.

    Too many bugs to be dependable anymore, used to love it ): Would love to see it restored to original glory, that’s why I’m leaving this comment. Thank you for all your hard work.

  19. hello first of all thanks for this great app, the best for osX!
    i have a bug to report:
    – in fat32 names shouldn’t include some specific symbols, the app should recognize those chars on the game names and cut them off while naming stuff. now the app just gives an importing error and that’s it

    and i also have few feature suggestions:
    – an option to save naming patterns
    – a panel to configure the hd paths structure: like wii games in /wbfs, gc games /games

    1. Yes, FAT32 only supports a limited range of characters. For the moment being, if you encounter a conversion/renaming error make sure to validate the title of the game or any other game detail which may contain strange characters.

      1. I’m having trouble creating partitions on OS X sierra on my USB so that I can format it to wbfs. Any help with that

        1. 1) Open the Disk Utility (in /Applications/Utilities).
          2) Select your USB drive and click on the Erase button in the toolbar.
          3) Make sure you select Mac OS Extended (Journaled) and GUID Partition Table, then click on Erase to confirm.
          4) Now you can click on the Partition button in the toolbar to add some more partitions.

  20. Thank you very much for this app!!! It’s fantastic.
    This is my problem: I have one Witgui 2.2.6 installation on El Capitan and when I open database to browse it I find also italian titles. Another installation of witgui 2.2.6 on Sierra and when I open database the italian titles are miss. The two database are updated.
    One examples if I search croods on database:

    El Capinat results:
    – DreamWorks The Croods: Prehistoric Party! & Rise …
    – The Croods: Prehistoric Party!
    – I Croods: Festa Preistorica!

    Sierra results:
    – DreamWorks The Croods: Prehistoric Party! & Rise …
    – The Croods: Prehistoric Party!
    – The Croods: Prehistoric Party!

    There are two times in english.
    Thank you for the help.

    1. It seems like Sierra changed the format in which languages are saved. This issue will be resolved with the next update.

  21. Thank you so much for making this!!! I haven’t found any GUI as good as this for wit. Really really appreciate it. Well done.

    1. Subfolder searching can be enabled from the options in the Open panel. Dropping folder onto the Quick Start window to open them will be added to the next update.

      1. Subfolders were well hidden! Pressing space bar to get the info like quicklook would be nice too. Pressing ⌘-I is a bit awkward.

  22. Thank you so much for maintaining this amazing application. It is very much appreciated.

    I have one question. I see all the covers when browsing in witgui but when I browse the games in the USB loader on the wii before choosing a game to play, the covers are not there, only a bland image and fortunately the name of the game.

    Anyway to have witgui sync the cover art so it is saved on the hard drive? Or am I doing something wrong perhaps 🙂

    1. The covers that you see in the app are downloaded from the internet and are saved locally on your Mac, they cannot be saved in the games directly. If you want to see the covers in your USB Loader, you should make sure that you have an internet connection on the Wii and the loader supports downloading the covers.

      1. Thanks a lot for the fast reply. Good to know so I do not loose time trying to find an option in the app that does not exist 🙂

        Again, great work with the tool.

  23. Hi, using WitGUI for WII ISOs and wbfs files works great. However, whenever I try to copy over a Gamecube ISO to my wbfs-formatted USB stick, it looks successful in WitGUI but on USBLoaderGX on the Wii these games always show up in the list with no title or details, and won’t load. Any suggestions? Are GC games meant to go on the wbfs partition? Thanks!

    1. GameCube games don’t work out of the box when using a USB Loader, you first have to install the necessary components on your Wii.

  24. Is it possible to export scrubbed gamecube ISO files? The exported ISO files are now always 4.7GB. When i’m using windows tools the gamecube ISO’s are a lot smaller (1.46 GB)

    1. ISO images will always occupy 4.7 GB when created with wit. You can use a WBFS partition or save the games in the wbfs format, which takes care of scrubbing automatically.

  25. It says 25 partitions/discs found…but doesn’t let me choose none of them….the arrow appears faded and doesn’t allow to select nothing

    1. To open a FAT partition or any other partition that is visible in the Finder, please select the “Folder” button in the Quick Start window ant not the “WBFS partition” button.

  26. Hi! Thanks for your great little programm. Works like a charm. I have one question: I want to transfer my games to a bigger drive cause I ran out of space. Is it possible to copy files from one drive to another?

  27. I have games on a FAT-32 formatted external drive, using El Capitan. Every time I open witgui or I refresh the list I get a popup error:

    ‘/Volumes/WIIHDD/wbfs’ could not be opened correctly.
    If you have ‘Search in subdirectories’ checked on the Open panel, try to disable it. If the problem persists, make sure you have the privileges to read this file and that you are not following a broken link.

    I do have “Search in subdirectories” checked as each game is in its own directory. If I uncheck that I see no games. However with it checked it lists all the games fine and I can add new ones without a problem, so I don’t know if the error is genuine.

    Also please change the alphabetical ordering to be case insensitive. “de Blob” for example is at the end of my list, right after Zack & Wiki.

    1. Probably the game wasn’t ripped correctly. You can try the following:
      1) Open the Console (in /Applications/Utilities)
      2) Type „Witgui“ in the search field
      3) Look for a double exclamation mark (!!) which usually marks an error message.

  28. hi thanks great job wonderful tool my thing is i would like to select all folders hard drive and view all games in one windows and back up the hard drive to another dont know if this is already done in the software if it is dont know how to do it thanks

    1. On Mac OS El Capitan, you have to enable the option “Search in subdirectories” in the Open panel (you first have to click the Option button).

  29. Sooooo. After some mucking about I have the games displayed in witgui interface. And I have an iso on my desktop. I drag iso to interface and a green plus shows up. I release finger from mouse, and it pops back to origin and no copy to witgui. So a big HUH?? Was a WBFS user til 3 years ago and now trying to add games and pass on drive to Daughter.

    1. In Witgui, you also have to install wit in order to add games to a WBFS partition (wwt is not enough). There will be an alert in the next update in case you haven’t installed wit.

  30. I just bought I new external HD to use with my Wii and I want to free the older one. But I can’t seem to be able to copy the games between a WBFS HD to the other.
    The only workaround I found was to copy a game from one WBFS HD to my computer, then from my computer to the new WBFS HD…

  31. Witgui cant found the disk, only when i tried to give format to it. So i ned to format the disk before I can upload some games to the disk, it doesnt work in antoher way.

    1. You probably used a software that is not compatible with Witgui. Please back up your games and try reformatting your drive with Witgui.

      1. Hi All,
        Many thanks for the great piece of software – I am just reporting what I think to be the same issue as Isaac: witgui only recognizes my drive if I format it first. I can not just add an iso to the hdd, I always need to format, and recopy all to the drive.
        I am running El Captain 10.11.2 – I only used witgui and I am operating under the case by case sudo access method (which works apparently properly to format the drive)
        Hope you can help me manage the drive more efficiently! thanks anyway

        1. The cause of this issue couldn’t be identified yet, but in update 2.2.4 Witgui will use an alternative method of finding partitions which should always work.

  32. I formatted my USB with Witgui but now my MAC doesn’t recognise it. As soon as I plug it in I receive a message that my USB cannot be read by the computer. I can access it to see the game that I have installed but that’s about it. The problem is that I haven’t installed USB Loader or anything and I cannot run the game from it. Basically my brand new USB is now useless. Can anyone help me? Thanks!

    1. Once a partition is WBFS formatted, you can make it readable by Mac again by using the Disk Utility (in /Applications/Utilities), selecting your drive and formatting as either FAT or HFS+. Please make sure that you know what you do before formatting a drive, since this could erase any other data present on it.

    2. Don’t worry. If you format to read games, MAC will not read it. To use on the wii you need to set up with home-brew then USB loader (or such) on the wii. Then you can plug in drive and good to go.

  33. Hi, i just downloaded the last update and it won’t let me drag and drop a game from one partition to another, is there a new way to transfer/convert a game?

    thanks 🙂

    1. There is a bug in version 2.2.2 where you can only drag games to the lower left corner of a window when in icon view mode. This will be fixed in the next update.

  34. Hi There,

    thanks for the great tool,
    What would be the Terminal command if you want to revert enable root for everyone please. I am afraid this was the only way to upload the games. I would like to revert the process if I can. Please help

    1. In my experience, it is necessary to make wwt executable as root to add games to WBFS partitions. If you want to undo this action, you can just download wwt again from the File menu.

  35. When opening my WBFS partitioned drive, it opens the appropriate window, loads the games for about 2 seconds, then crashes. I have been using the same drive for about a week now and suddenly have this problem.

    1. Just wanted to say I’m experiencing the same thing. The WBFS partitioned disk worked fine yesterday and today crashes as soon as I try to open it. The only thing I can think of that I did different since the last time I used that disk was I used the witgui feature of created a WBFS partition on a different disk.
