English Amiga Board - View Single Post - Asking for TFMX file format specs in order to implement it in a player

I'm afraid it is not that easy.

First, there is the TFMX-SONG (aka TFMX or TFMX Pro) format, and the COSO (COmpressed SOng) format, itself having sub-formats (COSO, MMME, etc). One can be (more or less) converted into the other.

Second, TFMX in itself has many variants which may look very similar and difficult to identify.
There is Amiga 4 channel, Amiga 7 channel, and Atari ST synth formats, which all work differently. There even exists some variants for Atari with samples (e.g. Wings of Death), which some players will identify as Amiga files and play wrongly.

In addition some details changed from version to version, without touching the file format much (if any) and some songs will play wrong if this is not taken into account. For example, musics from Dragonflight and Amberstar are incompatible (some effect differs). Musics from Monkey Island usually fail as well.

In short, TFMX is a complete mess and no single program can play them all without errors.

If you really want to go into this, good luck. The best source for TFMX replayers might be the Wanted Team page.
