CBMD
CBMD - CTR Banner Model Data
This page describes the format used for banners' models. These are stored in 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.
