NUS (short for Nintendo Update Server) is a set of HTTP servers used to serve updates for Nintendo's consoles. For the Wii and Wii U, this server is located at http://nus.cdn.shop.wii.com.

Protocol

The Wii uses user agent wii libnup/1.0 for all requests.

Query a list of titles

To query a list of titles, a SOAP request is sent to /nus/services/NetUpdateSOAP, with action urn:nus.wsapi.broadon.com/. The result is an XML structure containing all titles that require updating.

Request structure

GetSystemUpdateRequest xmlns=urn:nus.wsapi.broadon.com

Version - always 1.0?
MessageId - unknown
DeviceId - unknown
RegionId - USA, JAP, EUR, or KOR
CountryCode - unknown
Several TitleVersion structs:
TitleId - 16-digit title ID in hex
Version - decimal version
Attribute - unknown
AuditData - unknown

Response structure

GetSystemUpdateResponse xmlns=urn:nus.wsapi.broadon.com

Version - same as version in request?
MessageId - same as MessageId from client
DeviceId - same as DeviceId from client
ErrorCode - 0 on success
ContentPrefixURL - always https://nus.cdn.shop.wii.com/ccs/download (HTTP before 2.0rev02)
UncachedPrefixURL - always http://ccs.shop.wii.com/ccs/download (HTTP before 2.0rev02)
Several TitleVersion structs:
TitleId - 16-digit title ID in hex
Version - latest title version available
FsSize - size in bytes?
UploadAuditData - unknown, possibly boolean?

Download a TMD, ticket, or content

These can be downloaded from /ccs/download/<titleid>/<name>, where titleid is the title ID in hex, and name is one of three things:

  • tmd[version] - downloads the TMD for the version provided, or the latest version if no version is provided
  • cetk - downloads the ticket (free titles only)
  • <contentid> - downloads a specific content
