WIP!!

NKit documentation is WIP. It will be added to as people ask questions and raise issues...

Overview

NKit is a Nintendo ToolKit that can Recover and Preserve Wii and GameCube disc images

Recovery is the ability to rebuild source images to match the known good images verified by Redump

Preserve is the ability to shrink any image and convert it back to the source iso

NKit can convert to ISO and NKit format. The NKit format is designed to shrink an image to it's smallest while ensuring it can be restored back to the original source data. NKit images are also playable by Dolphin

Key Uses

• Unscrub/Rebuild Wii/GC images from scrubbed/header+region hacked/wbfs(file)/iso.dec/iso/gcz to match Redump good images
• Convert Wii/GC images to NKit format (small, playable, reversible) - with optional gcz compression
• Preserve and shrink Scrubbed and Custom images
• Preserve Wii images with controlled removal of update partition

Recovery

• Recover scrubbed, header/region hacked images to match Redump verified images

History

Version 1.0

A lot of effort has gone in to ensuring this version is as stable and reliable as possible. The NKit Format is stable and reliable. Always use FullVerify as it's always accurate as are the Hashes when CalculateHashes is on. Please report any issues and ask any questions.

• Fixed a bug in the GC Format (This alters 12 of the GC Redump images - just reencode them if you verify against NKit dats)
• Added Wii NKit Format (100% Redump tested, Scrubbed & Custom Support)
• 2 Windows (Sorry Linux & Mac users) GUI Apps added, including file extraction

Version 0.5

First stable version

Future Features

• Release the code (Yes, this WILL happen)
• WBFS output (for easy output for Wii Hardware use)
• CISO reading
• Port the code to dotnet core 3 when it's released (GUIs too)
• Port to Android
