Overview[edit]

These are titles which provide downloadable content to a specific title. The reason why these titles can only be purchased in game, is because all DLC content is under a set of title(s), downloading via the eShop would download all DLC content. And because all DLC content is under a set of title(s), they are viewed as one(?) title in system settings, and individual DLC can only be deleted from within the game which uses the DLC.

The titleID-low for DLC is: ((uniqueID<<8) | DLC_title_index). DLC_title_index starts at zero. Each DLC item is grouped under a DLC_title_index. Usually an application only has one DLC_title_index, but for applications which have a *lot* of DLC there's more than one DLC_title_index(JPN Home Menu for themes for example).

Every DLC title include NCCH partitions. The first one is always content metadata.

Content metadata structure[edit]

The first NCCH partition of a DLC title. It determines region, language and DLC icons. The ExeFS section of content metadata only contains icon section. The RomFS section contains "icons" directory, a MetaDataContentHeader.bin file and some ContentInfoArchive files.
