NKit 2 is a multipurpose disc image processor library with command line and GUI frontends available.
The goal of NKit is to help to centralise various apps that perform various game disc image manipulations for (currently) mainly video game consoles, like the Gamecube, Wii, Wii U, PS3 and more.
NKit requires the dotnet 6 runtime (or .NetFramework4.8 for the Windows 7 version).
This is available as a package in many Linux distros or can be downloaded from here.
Specify the task to perform and then list the image(s), folder(s) or even archive(s) to perform the ask on.
For example: To convert a selection of Wii images in various formats to Dolphin RVZ:
nkit -task convert image_1.wbfs image_2.iso folder_of_images archive_of_images.zip
See the usage page for all arguments and details, and the processing tasks page for all currently supported tasks.
