ShowMiiWads

Just like computers read different kinds of files depending on purpose, so do console rely on their own supported formats. This is exactly what ShowMiiWads has in store for you, giving you the possibility to edit, and update Nintendo Wii WAD files, in a powerful, yet intuitive environment.

First of all, the application skips you the time and effort needed to go through a setup process, and can be launched right after download. This enables you to carry it on a thumb drive to use on other computers, without having to worry that stability gets affected, since registries are not modified during the process.

What you do need to look after are WAD target files. It’s best to make a backup of the target file before editing it, otherwise you risk damaging your console beyond repair. There’s no possibility to do this through the application’s set of features, but a simple copy and paste operation can suffice.

WAD files are mostly archives which contain the required components to make a Wii gaming console functional, with info related to system menus, IOS, channels, and more. These are also responsible for game functionality, so any editing, and possible consequences of using an edited WAD file are your own responsibility.

Loading a file can easily be done through drag and drop, or selecting an entire directory for its content. Editing involves basic operations like copy, cut, paste, rename, or delete. However, there are also dedicated options like changing channel title, modifying the title ID, changing IOS slot, title version, region flag, extracting different resource types, previewing, and a few more.

Additional tools are at your disposal. Selected from a dedicated menu, these can be used to pack all changes in a different WAD file, unpack the U8 archive, or pack in with specific parameters, convert TPL to image or the other way around, and extract BootMii dump, which comes in handy for analyzing any issues when reading a custom WAD file.

All things considered, we come to the conclusion that ShowMiiWads is a powerful WAD file viewer and editor, but should be used with caution. Any editing or consequences are your own responsibilities, since erroneous changes can damage the target device.
