WARNING!

This tool creates WAD files. If it should happen to have issues during this procedure, installing corrupt WAD files could BRICK your Wii. Don't use this program if you are not sure of what it accomplishes. No warranty provided, no responsibility on me if you brick anything!

Usage

Load the program, and enter a title ID and optionally a version number. Title IDs can be found in the Title database or IOS History.

Looking below, evaluate whether the checkboxes have the desired values.

Wii Wad Files Download

Keep Encrypted Contents: Leaves the 00000000, 00000001, etc. files present. These are what make up a WAD, but are not necessary to keep if you only want a WAD.
Create Decrypted Contents: Uses the Wii/DSi key to create corresponding 00000000.app, 00000001.app, etc. decrypted NUS content files.
Pack WAD: This creates a WAD file of the desired NUS title. This is only available for Wii titles.
Use Local Files: This skips downloading files that appear to be present in your local title library.
Patch IOS: This, in conjunction with Pack WAD, patches NUS IOS titles with various exploit-enabling 'features.'

Press Start NUS Download, and wait for the title download to finish. When completed, you can find the downloaded/created files in titlestitleIdversion*

System WADs can be installed using any normal homebrew installer on the Wii.

Protips

You cannot get free games with NUSD.
Title IDs are 16 characters long: no dashes/spaces/symbols.
Having a (Mismatch) message is OK. It relates only to the difference between TMD and actual content sizes.
Entering no version number will get the latest one. Remember that System Menu's have separate versions for each region, so you may not want the latest one.
A failure to download a TMD means either your internet is not connected or you are entering incorrect information.
A failure to download cetk (tickets) means that the title can still be downloaded, but not packed or decrypted.
This program requires the Microsoft .NET Framework 2.0 to run!

WhyWhat?

There are several reasons to use this program.

Avoid unnecessary pirating of System WADs (IOS modules, System Menus, etc.)
Obtain a specific version of a System Title (Menu 3.2U, etc.)
Simplification of download and packing process.
Decrypt contents straight from NUS.

What this does NOT do:

Package VC/WiiWare/DSiWare needing an individual ticket.
Decrypt WC/WiiWare/DSiWare titles (no tickets!)

Title IDs

Wiibrew has quite the collection of Title IDs for use with NUSD. For most general titles, check out the Title database. For IOS ids specifically, check out the IOS History.

New to v1.2 is a local database of title IDs in the database.xml file. To access this, simply click the database button in NUSD, and select a title based on category.

Database

The NUSD database is stored in the database.xml file, which should be placed in the same directory as the executable. It is a simple, formatted XML document. A separate page has been dedicated to the database, here you can find the latest copy as well as how to format the file.

A lot of information is portrayed in the database icons for each title. Here's what the color codes represent:

Green: The title has a ticket available.Orange: No ticket is available.Red: A notice/danger text is present in the database. These titles are usually crucial to the Wii.

For DSi Users: Versions 1/9 and later support a dsidatabase.xml, which can be found on DSiBrew.

Credits

NUSD was written by WB3000, but much of the code would not have been possible without the help of #WiiDev, in particular Crediar, comex, Galaxy, and SquidMan. The advice and source code provided by them made this program possible.

Releases post-v1.3 had significant contributions by lukegb.

Update History

v1.9 - January 19th, 2011

This build is intended to provide updated DSi features to users before the release of v2.0.

The DSi Common Key is NOT embedded into this release. Once it inevitably spreads and becomes common place, I could embed the key. Many sites do not want any trace of it, so this build respects this request.

Multiple GUI changes
DSi Decryption support fix
DSi Database support (dsidatabase.xml)
Supported by libWiiSharp framework
Improved local scripts support
New directory structure (titlestitleidversion*)
Script loading from database.xml
IOS Patching
Reads key.bin, kkey.bin, and dsikey.bin
WAD file SaveAs support
Whatever else happened in the months between...

CLI Mode did not officially make it to this build. Sorry!

v1.5a Beta (bugfix release) - July 1st, 2010

Fixed crash when opening Virtual Console menu

v1.5 Beta - June 29th, 2010

Moved update database option to Extras menu, added ability to download database if none exists
Added ability to download common key (via HackMii blog) if does not exist
Added ability to accept hex STRING versions of the common key
Made the database reading multi-threaded, so as not to delay GUI loading.

Unofficial v1.4 (still beta) - April 16, 2010

Some bugfixes (Linux-oriented) - lukegb (probably the only changes I'll be committing)
Fixes/GUI changes - WB3000

Note: this version is highly untested, and I pushed it out mostly because I wanted the Linux-related path fixes to go out.

Database updates via the GUI.
Simulated Wii Updates for each region.
