NKit is a Nintendo ToolKit that is able to recover and preserve Wii and GameCube disc images. It has the ability to rebuild the source images to match the verified good images from Redump, and also has the ability to shrink any image and convert it back to the original source ISO.

NKit can convert to both ISO and the NKit format. The NKit format is specifically designed to shrink the image to its smallest size while still ensuring that it can be restored back to the original source data. These NKit images are also compatible with Dolphin, Swiss, and Nintendont but not yet with Wii USB Loaders.

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

Changelog

Version 1.4

Fixed Hash Preservation for images with corrupt FSTs
Fixed "Truncated RVT-R image detected..." message being shown incorrectly
FST filenames are now correctly encoded with Shift-JIS
There should be no breaking changes or conversion difference for any previously successfully verified images. Please report any issues.

Version 1.3

Added RVT-H Detection. This is not currently supported - An error is thrown and logged
Fixed NkitReencode. It was always reencoding and not copying the NKit file when converting nkit.iso <-> nkit.gcz
Fixed Verify not outputting any log detail messages e.g. When a removed Update Partition is required to verify and was not present - no message was output, it just failed
Moved the SummaryLog to the Processed folder rather than the app folder to make it more obvious
Added settings home support. ~ at the start of a Path will insert the user's home directory (all OSs)
Revert To .Net 4.6.1 - mono wasn't handling 4.7.2 very well. The app well be ported to dotnet core 3 soon
ProcessorApp: Added failure message to log errors (same as cmldline exe output)
ProcessorApp: Disabled the checkbox for 'Remove and Preserve Wii Update Partitions' when Recovering or Converting to iso
ProcessorApp: Fixed checkbox for 'Remove and Preserve Wii Update Partitions' not being set on app load
ProcessorApp: Fixed progress .1.2.3... text alignment in the log output
ProcessorApp: Fixed the output log being truncated when a partition ID contained a null char
There should be no breaking changes or conversion difference for any previously successfully verified images. Please report any issues.

Version 1.2

Updated to .Net 4.7.2 (Preparation for long file name support)
Added support for images that a file ends on a non 4 byte alignment (for 1 shrunk GC demo)
Added support for images that have no Magic (default to GC - for 1 GC early system disc)
Fixed the ExtractionApp GC Region always showing Japan
Corrected NKitExtracted path in config
Added missing Wii Jakers config entry
Fixed Double "Truncated RVT-R" message
Fixed ProcessorApp Gui Exception not being captured
Fixed Drag Drop message being cleared when a non supported file is dropped
Modified some public class accessibility to make them internal
There should be no breaking changes or conversion difference for any previously successfully verified images. Please report any issues.

Version 1.1

NKit format fix: Fixed a bug when converting Wii to NKit. This was introduced during the last 2 days of development while adding support for a Customs preservation bug.
Fixed a minor ProcessingApp bug where the output path wouldn't be used.

Any Converted NKit Wii images from v1.0 are not corrupt. Just not 100% correct to the format. Reconverting will correct the issue. Make sure NKitReencode is set to true if reconverting images that were made with v1.0.

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
