Another sleepless night mostly filled creatively.
Another PSG only tune, and something very different from all else. Also, just 2 percussion patterns LOL
I am quite häppy with the result, especially considering it only took like 4 hours to make.

Sega Master System can do 3 channels of 50% square waves + 1 channel of pseudo-random white noise or 6.25% square waves. The 4th channel has 3 fixed frequencies or it can use the frequency of the 3rd channel. This tune uses the fixed frequencies mode. I have to make one tune now that uses the other mode and also 6.25% squares capability.

Enjoy !
