IDBE is Nintendo's title icon database. Entries contain title icon, region, and name (in various languages). All game titles are on the server (excluding DSiWare?), including demos and updates.

<nowiki>https://idbe-ctr.cdn.nintendo.net</nowiki>/icondata/'''%02X'''/'''%016llX'''-'''%d'''.idbe
'''%02X''' seems to always be 0x10 (?)
'''%016llX''' is the title id.
'''%d''' is an optional title version.
== Encryption ==
The icon database is encrypted with AES-128 CBC. All icons use the same IV and one of 4 possible keys (as specified by the key index in the header).
The IV/keys are likely hardcoded on the 3DS, but not sure where. [http://wiiubrew.org/wiki/Nn_idbe.rpl#Encryption They are also on the WiiU].
