OPL FM on the Amiga?
« on: November 22, 2011, 11:46:08 PM »
I've heard bits and pieces about some Amiga software using a bridgeboard plus an Adlib or Sound Blaster to get Yamaha FM on the Amiga. Being a fan of FM chips, I'd like to find out more about this, especially if there's information I could use to incorporate that capability into my own programs. I thought I saw an MSX emulator that did on Aminet, but it turns out it actually uses a Picasso IV addon with an OPL3 chip; what software, if any, actually did this?

Well, yes, but A. that would require much more CPU horsepower, and B. Adplug's emulation is...so-so. Most OPL2/3 emulators vary significantly from the sound of an actual chip, for some reason (it's particularily evident in the percussion sounds, but lots of things differ noticeably.)

There's this one from July, but the only reference to OPL capability is in regards to a mega-multifunction ISA card that includes an OPL3 chip, which apparently didn't even work :/

Well, yeah, that would work. My thought, though, was more along the lines of having it as an obscure little option for music output in future game releases, not so much because I need FM on my Amiga.
