ymf724 has xg inside, and has no wt header.
I have a GUS classic and I wanted to put something inside for SB pro/16 compatibility. YMF724 gave me the option of having GM in some games (DOS games in Win98). I wanted to put SB16 on other PC, but I'm afraid that I might have some compatibility issues with yamaha, even though it has sblink connected. I understand that SB16 has worst sound quality, But i changed the opamps for TL074, I know I must recalculate gains, but sound is so much cleaner than it was, no more hiss, or distortion in OPL3 when we have bass or drums. My machine is almost ready, I just need an USB2.0 card with internal idc10 pin connector and that's it.
