[Scummvm-devel] sound through opl3 (ym3812) emulation?

Hello! 
I've written a imuse player which uses opl3 through fmopl.c which I got from MAME I think.

What remains is to make it in sync with the current imuse, since I've made changes to the imuse structures after I wrote the fmopl.c player.

Best Regards,
Ludvig Strigeus
