The Nintendo 3DS utilizes a similar title-based organization as seen in the Wii and DSi platforms. The same update server is being used as was with the DSi, however a new common key has been introduced.

The organization of Title IDs has not been documented fully yet. It's unknown how regions are determined in titleids if at all.
