== Sega == @@LOGO@@logo_sega.png@@Sega@@musiques_sega.en@@ The Sega Genesis, known as the Mega Drive in most regions outside North America, is a 16-bit home video game console which was developed and sold by Sega Enterprises, Ltd. The Genesis was Sega's third console and the successor to the Master System. Sega first released the console as the Mega Drive in Japan in 1988. The system produces sound by way of a Yamaha YM2612 FM synthesizer and a Texas Instruments SN76489A PSG, the latter of which is integrated with the Video Display Processor (VDP). The Z80 processor was primarily used to directly control both sound chips, particularly later in the console's lifespan, producing stereo music and sound effects. Most revisions of the original system contain the YM2612 and a separate YM7101 VDP; these two chips were later integrated into a single custom chip (YM3438) for the model 2 and later revisions.
