A '''title''' is a group of code and/or data that the Wii U uses. Titles generally represent apps such as [[OSes]] or apps on the [[System Menu]], although other titles also exist, such as [[Version Data]].

== Title IDs ==
Each title is given a 64-bit title ID that uniquely identifies the title; if two titles have the same ID, then they are most likely different versions of the same title.

The upper 32 bits of each ID describe general properties of the title, while the low 32 bits are the title itself, and usually uniquely identify the title.

== Types of titles ==
The following types of titles have been seen.
{| class="wikitable sortable"
! Upper 32
! Description
|-
| 00050000
| eShop title
|-
| 00050002
| eShop title demo / Kiosk Interactive Demo
|-
| 0005000C

|-
| 0005000E

|-
| 0005001B
| System Data Archive, last byte OS version
|-

| Applet title, last byte OS version
|}

See [https://wiibrew.org/wiki/Title WiiBrew] for info on [[WiiMode]] titles.

The upper 16 bits seem to be the the platform ID, which is 5 for the Wii U. The lower 16 bits appear to be a bitmask; the following bits are recognized:
