Fire & Forget II MS-DOS FM Synthesis Soundtrack

Описание: Fire & Forget II was developed by Titus France SA and released in 1990. The composer is unknown. The game only supports PC Speaker and Adlib/Sound Blaster, so the Adlib/Sound Blaster music is presented here. The music is played back with the assistance of SBVGM. Songs were captured to .VGM by replacing the sound ID at the title screen.

11:42 - Title Screen (OPL2 - no waveform select)

Why is the title screen track included twice? The explanation is a bit involved. The Yamaha YM3812 OPL2 FM Synthesis chip was able to select one of four waveforms, sine (default), half-sine, absolute-sine and pseudo-sawtooth. There is data in the title screen track indicating that the composer appears to have intended to use one of the three alternate waveforms. However, the sound driver for this game disables the waveform select enable bit in one of the OPL2 registers. The result is that the sine wave is used throughout the track.

When Fire & Forget II was released in 1990, the OPL2 chips found on the Adlib Music Card, the Sound Blaster, the Sound Master II and the Pro Audio Spectrum (and clones) were the only FM Synthesis chips available for composers and players. In 1992 the Yamaha YMF-262 OPL3 chip became available and was first used on the Adlib Gold, Pro Audio Spectrum Plus, Pro Audio Spectum 16, Sound Blaster Pro 2.0 and Sound Blaster 16. The Creative Labs Sound Blaster 16 MCD CT-1750 I used to record this video (except for Track 16) has a YMF-262 OPL3 chip. A little known difference between the OPL2 chip and the OPL3 chip is that there is no waveform select enable bit in the OPL3, waveform selection is always enabled. The result is with an OPL3 card, you can unintentionally (by the sound driver's perspective) hear the music as the composer intended.

Tracks 1-15 are as an OPL3 would play it, Track 16 is as an OPL2 would play track 1. Track 16 was recorded with a Creative Labs Sound Blaster 1.5 CT-1320.
