I've been working on a hardware VGM player that uses a YM2612 chip soldered out of a real Sega Genesis and PSG chip I found in a flee market. It was put together using an arduino microcontroller (an open source electronics prototyping platform). I got it to playback the music from Sonic 2 Emerald Hill Zone.

It is using an 8Mhz and 4Mhz oscillator until I can get the programmable oscillator using the real frequencies (PSG = 3579545). I havnt implemented all the VGM timing instructions or DAC (you wont hear any snare drums). I'll post the arduino source code and the parts list on my blog soon.
