From the project

A dual YM2203 sound chip board for Arduino Nano

This is an open source/open hardware sound board with two YM2203 FM sound chips driven by Arduino Nano. The YM2203 FM chips were used in several arcade game boards made in 80's. The design of the YM Bard sound board was actually based on a schematic of an arcade game.

The board allows you to experiment with YM2203 sound chips by writing the chip's register values from a PC over a serial port. It is also possible to stream an arcade game sound data over a serial port from a PC based emulator and produce authentic sound and music of an arcade game.
