To intercept the fifo variables, make your own WRITE8 function, so:

AM_DEVWRITE8("soundfifo1", fifo7200_device, data_byte_w, 0x000000ff)
change to something like:
AM_WRITE8(myfifo_w, 0x000000ff)

WRITE8_MEMBER(seibuspi_state::myfifo_w)
{
do your stuff...

m_soundfifo1->data_byte_w(space, 0, data);
}

You worded it a bit strangely. Is rfjets better or worse now?
