1111Todo :
12 - voice ( unemulated D7756C )
13 - controls/dips
12 - dump remaining sample roms
13 - improve controls/dips
1414 - better emulation of gfx bank switching (problematic in ganjaja)
1515 - is there 2 player mode ?

7    TODO:
8    - is there a doable method to dump the internal maskrom? :(
9    - low-level emulation
10    - watchdog? - according to uPD775x datasheet, the chip goes into standy mode
11      if CS/ST/RESET have not been accessed for more than 3 seconds
12    - convert to MAME modern device
