SN76489 test song (Sega Master System/Game Gear) by JRP2234 published on 2020-03-12T10:04:20Z I made this fairly quickly to test out the chip. the song was composed in 2 hours and is pretty messy. I wish I could use the lower octaves but it would not let me so I had to make the bass line in a higher octave. This chip is very limiting, not being able to change the pulse length really makes it limiting to what sounds it can produce.
