NUS Downloader, or NUSD, is a PC Utility designed to allow easy access to the resources present on Nintendo's Update Servers. Using this tool, you can download, pack, and decrypt many system titles into WADs ready to install.

Load the program, and enter a title ID and optionally a specific version number. Title IDs can be found in the WiiBrew Title database and IOS History pages, or loaded from the included database file.
Check whether you wish to Pack the title into a WAD, and whether the title is for the Wii or DSi. Note that DSi titles cannot be packed into WADs (They could but it would be useless).
