The DSiWare exported from a 3DS is located at "[[SD_Filesystem|sdmc]]:/Nintendo 3DS/<ID0>/<ID1>/Nintendo DSiWare". Filenames are same format as DSi: "<TitleID-Low>.bin". The keys/format for these files are completely different from [http://dsibrew.org/wiki/Tad DSi]. Like DSi, 3DS DSiWare exports seem to use [http://dsibrew.org/wiki/ES_block_encryption ES] block encryption. The below sizes include the 0x20-byte ES block metadata.

The keys/format for these files are completely different from [http://dsibrew.org/wiki/Tad DSi]. A DSiWare export to SD card from 3DS is ~0x3bc bytes smaller than an export from DSi.
The content sections starting at 0x44C0 are presumably about the same as DSi: TMD, SRL, savegame, banner.
