Yamaha YM2151

It would be cool to add module that emulates OPM chip (which was in Yamaha CX5M/II MSX computer, Sharp X68000, Sega System 16 and some others). It is a 4-operator FM chip, similar to YM2612 (OPN2), but more 'primitive' in a way, more raw sounding. It can produce some very interesting vintage digital synth sounds (here is example video). There are some excellent open source libraries (NukedOPM, an implementation from MAME), which can be used to implement module. YM2151 parameters are mostly the same as in Boss Fight module, so not much to change :)

I'm for it. I'm familiar with the MAME code style from working with the 2612 code, so I should be able to port this when I have time. I love the sounds that come out of this example video. Thanks for the post, great find!
