The Nintendo DSi uses the same title scheme and update servers as the Wii, but they introduced a new (currently unknown) common-key for the DSi title decryption.

As with on the Wii, the TMD for these titles may be fetched at e.g. http://nus.cdn.t.shop.nintendowifi.net/ccs/download/0003000f484e4c4a/tmd.

The official list of DSiWare titles is located here : http://www.nintendo.co.jp/ds/dsiware/titlelist.html

Each game specific url uses above 4 letter code.

Titles can be downloaded with NUS Downloader, an app that allows to download titles from NUS servers.
