M, it is assumed that M stands for Music, is an audio format created by Origin Systems and was used in several of their games from the late 1980s to the early 1990s. The format stores game music and, using drivers, can be sent to various output devices including AdLib, Creative Music System, Roland MT-32, Sound Master, SSI 2001, and Tandy 3 Voice, although not every game that used the M format supported each device.

The format does not store system exclusive data for any Roland devices, but is handled by the game itself before the song is to be played. If you plan on recording your own audio, you must first manually send the SysEx data to your device or the music will use incorrect instruments.

Versions

There are at least four versions of the M format. The first version was originally made for Times of Lore (DOS) where it is compressed with an LZW algorithm. The AdLib and Creative Music System formats are stored in the M files, and the Tandy 3 Voice music is stored in separate TM files. A second version was used in Ultima VI: The False Prophet (DOS) which uses the same LZW compression, but it incorporates the Tandy music into the M file and adds support for the SSI 2001 and Sound Master. The third version was used in Bad Blood (DOS) and appears to use a new, and, as of yet unidentified, compression format. The fourth version is used in the PC-9801 conversion of Ultima 6 which uses a different and yet unknown compression and adds support for the YM2608 chip. Also, in this version there is a duplicate *.M file with a "F_" prefix on all of the file names for an unknown reason.

Although the two Worlds of Ultima games (Martian Dreams and Savage Empire) use the Ultima 6 engine, they use the OMI audio format, which was also used in the first couple Wing Commander games.

How to Obtain

For Times of Lore, Ultima 6, and Bad Blood, the M files are located in the root install folder.

Technical

If you want to study the structure of M files, they can be decompressed with the Ultima LZW Decompressor, although AdPlug can only play compressed files.
