 * 86Box    A hypervisor and IBM PC system emulator that specializes in
 *          running old operating systems and software designed for IBM
 *          PC systems and compatibles from 1981 through fairly recent
 *          system designs based on the PCI bus.
 *
 *          This file is part of the 86Box distribution.
 *
 *          Interface to the actual OPL emulator.
 *
 * TODO:    Finish re-working this into a device_t, which requires a
 *          poll-like function for "update" so the sound card can call
 *          that and get a buffer-full of sample data.
