| Information stored about titles in these Title Database files are stored in two parts in a BDRI partition. Firstly in a Title Entry Table, and secondly in a Title Info Table.
| | This is a variant of [[Inner FAT|FAT filesystem]]. It consists one "root" directory and multiple "files". Each "file" is one title info entry described below. |

| == Title Entry Table == | |
| | |
| This contains 'Entries' for all the titles stored in the database. However this just appears to be an indexing table, the majority of title information is kept in a Title Info Table, which these index entries point to. Title Entries start immediately after the Title Entry Table Header. And there is no padding between entries.
| |
|
| |
|
| === Header ===
| | An entry contains information taken from both the application NCCH file(s) and TMD. |
