athrxx c22d9ea086 SAGA: (ITE/PC98) - add music support
We had an existing driver for that, so that could be hooked up rather quickly.

I haven't targeted the non-digital sfx for now, since I haven't fully analyzed whether they are even used. And it would require the reading of static data from the executable which we'd rather avoid.
