The DSiWare exported from a 3DS is located at "[[SD_Filesystem|sdmc]]:/Nintendo 3DS/<ID0>/<ID1>/Nintendo DSiWare". Filenames are same format as [http://dsibrew.org/wiki/Tad DSi]: "<TitleID-Low>.bin". The below sizes include the 0x20-byte block metadata.

DSiWare exported from 3DS use [[Nand/private/movable.sed|keyslots]] initialized by movable.sed. Each section is encrypted with AES-CBC.

DSiWare exported from 3DS use console-unique [[Nand/private/movable.sed|keyslots]] initialized by movable.sed. Each section is encrypted with AES-CBC.

The content sections are ordered the same way as DSi: TMD, SRL from content0, <content1-7 for format v2>, public.sav, and banner.sav when banner.sav exists. When the DSiWare export type is 7-11, the 12th content section is the private.sav, if it exists.(ContentX here is the .app data from TWL-NAND /title)

Each section begins with the payload encrypted data, followed by this block metadata. The hash used for the MAC is calculated over ~~the~~ the cleartext payload~~, however it's unknown how this hash is calculated~~. This hash used for generating the MAC is also stored in the footer.

Each section begins with the payload encrypted data, followed by this block metadata. The SHA-256 hash used for the MAC is calculated over the cleartext payload. This hash used for generating the MAC is also stored in the footer.
