Witgui is based on the wit and wwt executables which are part of the Wiimms ISO Tools. These tools are the core for listing and converting your games and most of the other features that Witgui offers.
Since version 2.0, wit and wwt can be downloaded from the File menu with a single click. After a successful download, the executables will be placed in the Application Support directory.
Since version 2.1, if you already have your own installation of wit or wwt, you can locate them by selecting “File > Locate wit/wwt …” while pressing the alt/option key. By default (since version 2.1.4), Witgui tries to locate wit and wwt in the following order: it first checks the supplied installation (if any), then searches in the Application Support directory and last in “/usr/local/bin”. When selecting “File > Download wit/wwt”, any reference to the custom installation path will be removed.
Starting from version 2.0 on, when composing the name of a file to convert, renaming a file or exporting a game list, special tags can be inserted into the text field by clicking on the “+” button on the left side. Starting from version 2.0.3, frequently used naming presets can be selected, too.
To add a custom naming preset to the list, compose your preset in the text field, click on the “+” button and hold the alt/option key. Select the first menu item which has changed to “Add current value to presets”.
To remove a naming preset from the list, click on the “+” button and hold the alt/option key. Select the menu item corresponding to the preset you want to remove (it will read “Clear: <preset>”).
Note: tags which are undefined or naming presets that contain tags which are undefined for any of the selected games will be disabled.
To uninstall Witgui completely, you have to manually remove the following directory:
and the following file:
where ~ denotes your home directory (i.e. /Users/myusername).
From Witgui 2.0 on, when you select a different option than “Don’t split” in the conversion modal panel, the created file will be split up into multiple files if it is larger than the selected option. This is necessary if you are going to play a game on a FAT partition, which doesn’t support files larger than 4GB.
To merge a multi-part file into one single file or split a single file into multiple parts, select the corresponding game in the source window and drag it to the destination window. Now select the same filetype as the original file (which you can see in the Filetype column of the game list) and select the desired split size from the popup menu (if you want to merge a multi-part file, select “Don’t”). Click on Save and wait till the conversion has finished.
From Witgui 2.0 on you have the chance to add games to WBFS partitions.
Before being able to open a WBFS partition, you have to install wwt and grant access to the partition. To open a WBFS partition, select “Open WBFS partition” from the File menu and choose your WBFS partition from the combo box.
Make sure you can see the game you want to transfer in the source window (which will usually represent a folder on your Mac). Once you’ve selected the game, you can drag it to the destination window which represents the WBFS partition. A panel will appear asking if you want to keep only the CHAN and DATA partitions: usually this option reduces the final size of the game, but if you are unsure, just leave it unchecked. When you click the OK button, the conversion will start and you can follow the progress by clicking the Conversions button on the right side of the toolbar.
To gain access to a WBFS partition or to format a partition as WBFS you first need to install wwt, which you are prompted to download when you launch Witgui for the first time.
Besides, you somehow need to have privileged permissions. The first time you download wwt you’ll be prompted whether to set it automatically to be executable as root by everyone: accepting is the easiest way to do it (this is not as secure as the next option, so you are responsible for everything bad that could happen – which normally shouldn’t). Another way is to change the access rights of the partition every time you plug the device (where the partition is) in (just scroll down to see the instructions). The last option listed on this page describes how to set wwt to be executable as root by everyone manually (if you don’t trust Witgui to do it for you).
Changing access rights of a partition
- Open the Terminal (which you can find in Applications/Utilities), type
and press Return. You’ll get a list of the currently available drives.
- Plug in the device. An alert may appear saying that the device could not be mounted: click on “Ignore”. Now you have to type again in the Terminal the previous line of code (or simply press the UP arrow). By comparing the first to the second output you can get the name of the device/partition (it should be something like /dev/disk1).
sudo chmod 666 /dev/disk1
(or whatever name you got previously) and press Return. After typing your password (it won’t be printed on screen) and pressing Return again you can close the Terminal.
- Now you can access the partition as long as it is plugged in. Because the permissions get lost every time you plug the device out, you’ll have to repeat these steps if you want to access it after again.
Setting wwt to be executable as root by everyone
- Open the Terminal (which you can find in /Applications/Utilities).
- Type the following two lines (you’ll have to type your password after pressing Return the first time):
sudo chown root:wheel ~/Library/Application\ Support/Witgui/wwt
sudo chmod u+s ~/Library/Application\ Support/Witgui/wwt
