Planet X3 is a real-time strategy game for
MS-DOS computers.
This game is proposed by The 8-Bit Guy.
Actually the music is also worth listening to.
So let me analyze the music composition of the
SN76489 version.

The music of this version shares many
similarities with the OPL2 version, such as the
use of down glides to simulate drum sounds. Of
course, for SN76489,
only the software volume envelope can be used.
It is worth noting that the lowest bass of
SN76489 under 3.57MHZ main clock is only A1,
so you can hear a lot of A1/B1 as bass in the
music, but the OPL2 version can have a lower
Another point, if you listen carefully,
you will find that this group of tracks
time-multiplexes the third channel of SN76489
and the noise channel, which is very clever.
Some people will say that SN76489 can produce
sound from four channels at the same time,
but don't forget that if 4 channels are used at
the same time, then the noise channel will only
have 3 fixed frequencies (and these three
frequencies sound rough), but obviously it is
not here in this way.

At present, there are 3 versions of Planet X3
that can use VGM record:
OPL2, SN76489, PC-Speaker. But there is
actually a Covox version, because you can use
Covox to emulate the SN76489, and the sound
sounds very different from the SN76489 version,
like the SN76489 with a reduced frequency.
Actually Covox can also emulate OPL2,
but these two formats can only be recorded in
waveform, which doesn't seem to make much
Currently I have finished recording OPL2 and
SN76489 versions.
PC-Speaker version will also be released soon

This pack was made using DOSBox 0.74 VGM Mod.
