''Not to be confused with [[BMT (Material) (File Format)]].''

'''BMT''' ('''B'''inary '''M'''elody '''T'''able) files contain general information for Chords. ''Super Mario Galaxy'' and ''Super Mario Galaxy 2'' each contain only one '''BMT''' file, located in <code>AudioRes/Info/JaiMe.arc/me/metable.bmt</code>.<br>The main Chord data is contained in <code>defaultme.bme</code> from the same archive, see [[BME (File Format)]].

== Header ==
The '''BMT''' format contains no header magic like most files do. Instead, it consists of a Melody Count and Offsets. The size of the header is <code>0x10</code>.

== Melody Information ==
This section contains general information for Chords. It's size is <code>0x8 x Melody Count</code>. The following table lists the information defined for one Chord:
{| class="wikitable"
|-
! Offset
! Type
! Description
|-
| 0x00
| UInt8 (0x1)
| ? (mostly 0x64)
|-

|-
| 0x02
| UInt8 (0x1)
| ? (always 0x40)
|-
| 0x03

| ? (mostly 0x0A)
|-
| 0x04
| UInt8 (0x1)
| ? (always 0x00)
|-
| 0x05
| UInt8 (0x1)
| ? (mostly 0x1E)
|-
| 0x06
| UInt8 (0x1)
| ? (mostly 0x00)
|-
| 0x07
| UInt8 (0x1)
| ? (mostly 0x00)
|}

== Melody Names ==
This section simply contains names for each Chord and is likely irrelevant for the game's execution. It starts with a sub-section that contains offsets for each name. The size of this sub-section is <code>0x4 x Melody Count</code>.

=== Melody Name Offsets ===

=== Melody Name List ===
Each Chord name is stored in ANSI and ends with a Null-Terminator. The following names can be found in both games:
