A title is an executable installed on the Wii, installed to /title. Titles include the System Menu, IOS, and channels. Each title has a TMD and a ticket that are used for installation and launching. Titles are generally stored as WAD files.

While boot2 is stored in WAD format, it is not installed to /title, instead being installed to the first few blocks of the NAND.

Title IDs

A Title-ID is a 64-bit number that uniquely identifies a title. The high 32 bits are used to indicate the type of title, and the low 32 bits are used to identify the particular title. The title is installed to /title/HIGHBITS/LOWBITS/.

By convention, a Title-ID may either be written as 16 hex digits (e.g. 0000000100000002 or 00010000525a4445) or in two hexadecimal or ASCII parts (e.g. 1-2 or 10000-RZDE). The ASCII part is often written alone, due to there being no ambiguity with the other high 32 bits.
