The Sega Genesis also known as the Megadrive over in Europe and Japan, was a very popular 16-bit console, designed to compete with Nintendo.
It has two primary sound chips: The YM2612 and the SN76489

The Yamaha YM2612 has 6 channels: 5 FM channels and 1 FM/DAC channel. Also has hardpanned stereo.

The Texas Instruments SN76489 has 4 channels: 3 square channels and 1 noise channel.

It is worth noting that the '[[sms (format)[Sega Master System] also had the TI SN76489. It was used in the Genesis for backwards compatibility with the SMS, and it can be used in conjunction with the YM2612.
