The Sega Master System (commonly referred as
SMS for short), also known in some regions as the SG-1000 Mark III, is an 8-bit video game console manufactured by Sega starting in 1985.
It features just one soundchip for audio, which is a clone of the Texas Instruments SN76489, integrated as part of the Video Display Processor (hence why it is sometimes referred to as the "Sega VDP" rather than the "SN76489"). The only difference between the two is a different noise channel LSFR implementation. While the SN76489 and derivatives were used in many arcade boards and other systems, this format specifically only focuses on the Sega VDP variant found in the SMS.
It can also be found on the
Sega Genesis/Mega Drive and the Sega Game Gear. The latter adds hard-panned stereo functionality to all voices.
Each voice has access to 16 volume settings, similar to
YM2149F i.e. logarithmic rather than linear, the three square voices can access a 10-bit pitch range starting from ~110hz A-2. The noise channel has access to two modes: Random and Periodic, and can be tuned to one of three pitches, plus a mode that utilises Square 3's frequency.
One can use the periodic noise mode, set the pitch to follow the 3rd Square channel, and access lower notes than A-2 110hz. Note that you'll not be able to use Square 3 without also affecting the pitch of the noise channel in this mode.
