How to Obtain

PMM files usually have to be manually extracted from game files, a process that is different for pretty much every game that uses them.

Technical

All PMM files begin with "MTCVTS PSM 2.00" and 0 and, at offset 0x38, with "MDH" and 0. It is unknown what MTCVTS and MDH stand for.

A PMM file consists of one PMA file, up to 8 SMP (Palladix) files, a table with 4 volumes per sample, and a track that references these samples and volumes. The tempo of the PMM file is hooked to the PMA file. The samples are always played at their original frequency, which is what makes the format more suitable for drums and sound effects than melodies.

The format does not support stereo itself, but the official driver simply routes odd channels (with sound effects coming first and music last) to the left speaker and even channels to the right speaker.
