Stores strings used in games for localization. Can be found in a Wii Fit and Wii Fit Plus disc.
The file structure is composed by a header and sections. The essential sections are INF and DAT. The MID section can also be found on Wii Fit Plus disc, but the meaning is unknown.
The file is not completely known.
The endianess is Big Endian.
=== BMG header ===
The header is 32 bytes long.
Here's a description of it:
