−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, and it is probably for message IDs.+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:

−
−=== INF section ===
−
−It comes just after the BMG header. It contains information (like pointers) about the messages.

−==== INF data ====
−
−For each message, there is a INF data about it. At Wii Fit, there is just the message offset. At Wii Fit Plus, there is two another fields.

−=== MID section ===
−This section is probably message IDs. There appears to be one for each message and these can presumably be used by the wii to identify each message.

This is a warning to the owners of this site. My name is Shigeru Miyamoto and I am disappoint. You are breaking the DCMA laws. DCMA laws protect our freedoms far into the furture. There is over 9000 pages here and I want every single one of them gone by next week. This is not a threat but a promise. Every day after that week is up, I will sue you for $100,000 a day.
−Thank you for using Nintendo. We must ensure our freedoms through use of the DCMA. This not the analog millennium one passed in 1000 A.D., but the digital one.
