'''CBMD - CTR Banner Model Data'''

This page describes the format used for banners' models. These are stored in [[NCCH#CXI|CXI]] ExeFS:/banner and optionally in [[extdata]] exbanner.

CBMD is a container file for [[CGFX]] blocks. This is used for banners of titles you see in the home menu. BNR used for the app banners in the CXI/exbanner is the same as CBMD with CWAV at the end.

The common CGFX is used if the CGFX offset for the system region/language is zero. Those optional offsets ~~are unused~~ in extdata exbanner, separate CBMD banner files ~~can be used~~ for each region/language ~~instead~~.

The common [[CGFX]] is used if the CGFX offset for the system region/language is zero. Those optional offsets can be used in extdata exbanner, but separate CBMD banner files for each region/language can be used as well.

== CGFX ==

CGFX ~~might be~~ compressed ~~with LZSS?~~ For CXI banner CGFX, the decompressed size must be no larger than 0x80000.

[[CGFX]] are compressed using LZ11. For CXI banner CGFX, the decompressed size must be no larger than 0x80000.

Graphics containers. Contains: 3D Models, Shaders, Objects, Materials, Textures, etc. See [[CGFX]] for more information.

== BCWAV ==

The included [[BCWAV]] total channels must be 2, and the length of the audio must be 3 seconds or less, otherwise the sound will play incorrectly (beeping/clicking) or the model may fail to load.
