Moved the BCWAV info from the BCWAV page to here. (As it only applies to BCWAVs found in banners.)
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 can be used in extdata exbanner, but separate CBMD banner files for each region/language can be used as well.

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

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.
