The .mod filetype was the tracker module file for '[[Protracker], originally developed for the Commodore Amiga.  The original filetype had 4 channels of playback with 15 sample based instruments, though later versions upped the sample limit to 31 (which is supported by BotB).  Protracker was one of the first and most popular examples of '[Tracker[tracker] software, and the .mod format saw extensive use in the '[[demo scene[demoscene] and video game development.

While the .mod format originated with Protracker, these days there is a wide variety of software that can import and/or export the module.

'[t[1]The following applies/is interesting for more battle formats/composing in other trackers, so that's got to find a special place somewhere someday'[/t]
