StarTrekker / Star Tracker module
StarTrekker (Star Tracker in English) is a tracker for the Commodore Amiga. It produces modules with the extension .mod and .nt.
There are two forms of modules produced by StarTrekker - 4-channel and 8-channel. 4-channel mods are just the classic Amiga Module format with the ID string "FLT4" instead of "M.K.". The 8-channel format is slightly different and is described in the linked format spec. It can be identified by use of the ID string "FLT8".
