Not quite [OT] - YM2612

[']

I'm thinking of building an emulation of the Yamaha YM2612 chip. The chip was used in the Sega Mega Drive (known as the Genesis absolutely everywhere else except the UK).

I know it had 6 stereo channels of FM, and there must have been an LFO in there somewhere, but I know nothing about the signal routing or waveforms. I know it was similar to the chips used in the DX27 and DX100.

Does anyone have or know where I can get more technical information about the chip?

thanks

You could maybe try emailing someone who's made a megadrive emulator.

I've emailed richard bannister (www.bannister.org) who's emulated just about every console ever made, but as yet there's been no reply. Perhaps he's busy.

Thanks, i'll take a look. Finally come back to the board after a wonderful illness. Never walk 6 miles at 4am in freezing temperatures, you'll regret it for the next week...
