Current VGM format implementation in GStreamer (gstgme) only supports Sega Geneses (Mega Drive) and Sega Master System emulation. GStreamer also cannot handle the VGZ format (a shorthand for vgm.gz, a gzipped archive that contains a song) which means that users will currently have to extract the contents of their VGZ files to individual vgm files.
