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

URLs[edit]

%02X seems to always be 0x10 (?)

%016llX is the title id.

%d is an optional title version.

Encryption[edit]

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 hardcoded in the friend list applet. They are also on the WiiU.
