TODO:
    - start up sound (Sound #2 should play but does not

Done:
    - discrete sound
    - hooked up z80dma
    - combined memory maps
    - statics in mario_state struct
    - fixed save state issues
    - combine sh_* writes into one routine
    - Hooked up flipscreen
    - Changed monitor orientation to ROT0
    - fixed mario0110u1gre
    - rewrote driver, separate MACHINE_DRIVER(mario_audio)
    - palette from schematics
    - video timing from schematics
    - driver configuration switch Nintendo/Std Monitor
    - got rid of COLORTABLE
    - clocks as defines in .h
    - use XTAL_*

Mario Bros memory map (preliminary):
