My AWE 32 sitting in my garage has an OPL chip on it. I used it for everything in DOS back in the day. In fact, I think it was MORE compatible with legacy DOS games than my SB Pro was (I have that sitting around somewhere too).
Funny thing--when I went from my first 286 (Tandy 1000 TX) that had an Adlib card in it to my 386 w/SB Pro (gen 1 card, not 2), games that ran on my Tandy in Adlib, well a few in particular like Ultima 6 (not all), the sound would mess up and I would get crazy hissing from it on the SB Pro, hence killing my playability of some of these old games.
When I got the AWE 32 for my P100 it was able to play those old Adlib-compatible games again. I believe there was a flaw either in the drivers or the chips of those first gen SB Pro cards. I know, probably too much information but thought I'd share some experiences from an old dude who actually lived through that period.
