TODO:
|

- is there a doable method to dump the internal maskrom? :(
|

- low-level emulation
|

- watchdog? - according to uPD775x datasheet, the chip goes into standy mode
|

if CS/ST/RESET have not been accessed for more than 3 seconds
|

- convert to MAME modern device

- voice ( unemulated D7756C )

- controls/dips

- dump remaining sample roms
