Record marked as obsolete and not updated for a long time.
Game Music Creator was audio composing software, also known as a tracker, for Amiga computers. It was used to create music for games and other productions.
A gmc file contains music saved by Game Music Creator. It is a native project or song file for that software rather than a standard audio recording such as a WAV file.
The format is obsolete and is no longer in common use. The original software runs on Amiga systems, so modern support generally requires access to the original environment or a compatible Amiga emulator.
Open the gmc file with Game Music Creator on an Amiga computer. On a modern computer, an Amiga emulator configured with the original software may be required.
Because the format is obsolete, current general-purpose audio players are unlikely to open it directly.
Open the gmc file in Game Music Creator, or in an emulated Amiga environment, if access to the original music is required.
For conversion to a standard audio file, the music may need to be played back and recorded through an audio recording application; this produces a recording rather than a direct conversion of the original song data.
