i don't see why there should be any known issues, at least in windows98 it would be easy, but in dos it can be a bit tricky to set up.

I've got YMF 718 pretty well figured out. It's the AWE64G that is potentially the problem. Back when I bought this card new I never really messed with it much in DOS. Does the CTCM utility actually allow you to cherry pick which features you want on and off?

No, not in the way you would like it to. The AWE64 has three logical PnP devices: Gameport, Wavetable and SB16. The SB16 part includes the FX and OPL3 devices, so you can only turn them off together. Disabling the OPL3 clone only is not possible AFAIK. You can try to assign a different port than 0x388 to the OPL in CTCU, but I don't know if CTCU allows that.

Usually it's no problem when several OPL3 chips/clones sit on the 0x388 port. Just mute the one you don't want to hear (in this case the AWE64 FM/MIDI channel).
Also, you could leave the FM part of the AWE64 uninitialized by not running "aweutil /S" at startup. 😉

I suppose as long as it causes no conflicts and I don't have to listen to one of them, I am fine with having two OPL3s.

Does anyone run a YMF718 and AWE64 in the same system? Does it sound like a good combo?

Normally I'd like to just book up with the yamaha and turn the AWE64 on as needed.

Beware that some games access the OPL FM through the SoundBlaster I/O address range (normally starting at 220h) instead of the Adlib address I/O (normally starting at 388h). In that case changing the adlib address does not help you.

In other words: Soundblaster I/O range includes its own FM address. When using a classic adlib card there is one FM address, When using a soundblaster or compatible: there is a second FM address.

Stumbled upon this when I tried to add an additional AWE64 and hoped to practically disable its FM.

Don't remember if disabling the EMU got around that problem, as 5u3 suggests. AFAIK It does require you to use two bootup configs: one with EMU, one with proper FM on another card.

Edit: I remember now: When a game only uses the soundblaster I/O's then the FM will be send to the card that is used for sound FX, and cannot be routed to another. At most it can be muted, then you have no FM.
