It's a PT3 format chiptune music player written by Shiru for ESPboy project. The format is a kind of standard de-facto for AY-3-8910 chiptune music. This chip and its analogs have been used at:

About 25000 songs have been made since the mid-90s when it was first introduced.

The program emulates AY sound chip and plays PT3 files loaded into the SPIFFS. The sound is output through the sigma-delta modulation based DAC via the built-in speaker. It also supports I2S stereo DAC if connected (change define in the sketch, no run-time option to switch between outputs at the moment).

You can see and hear at this video the ESPboy DAC module play of few melodies from Shiru.
