This server provides icon data for 3DS, Wii U and Switch titles.
| Platform | Server |
|---|---|
| 3DS | https://idbe-ctr.cdn.nintendo.net |
| Wii U | https://idbe-wup.cdn.nintendo.net |
| Switch | https://idbe-hac.cdn.nintendo.net |
An icon file can be retrieved by sending a GET request to one of the following URLs:
| URL | Description |
|---|---|
/icondata/<id>/<titleid>.idbe | Provides the latest icon data for a title |
/icondata/<id>/<titleid>-<version>.idbe | Provides the icon data for a specific version of a title |
The title id must be specified as 16 uppercase hex digits. The first id should be (titleid >> 8) & 0xFF. For example, if the title id is 0005000010137D00 then the first id should be 7D. The server seems to ignore this value though.

Wii U:
| Offset | Size | Description |
|---|---|---|
| 0x2050 | 0x1002C | TGA file |
| 0x1207C | 4 | Unknown |
3DS:
| Offset | Size | Description |
|---|---|---|
| 0x2050 | 0x480 | 24x24 pixel RGB565 icon |
| 0x24D0 | 0x1200 | 48x48 pixel RGB565 icon |
The RGB565 icons use the same tiling method used in SMDH files, much like the rest of the 3DS. The IDBE format is likely based on the SMDH format. For more information on how this tiling system works, see https://3dbrew.org/wiki/SMDH#Icon_graphics
Although now explicitly stated to be made for the 3DS, this Node.js module works for these icons and is said to be based on existing SMDH tools https://npmjs.com/package/tiled-image-tools
