     3:   snes.c
     4: 
     5:   Driver file to handle emulation of the Nintendo Super NES.
     6: 
     7:   Anthony Kruize
     8:   Based on the original MESS driver by Lee Hammerton (aka Savoury Snax)
     9: 
    10:   Driver is preliminary right now.
    11:   Sound emulation currently consists of the SPC700 and that's about it. Without
    12:   the DSP being emulated, there's no sound even if the code is being executed.
    13:   I need to figure out how to get the 65816 and the SPC700 to stay in sync.
    14: 
    15:   The memory map included below is setup in a way to make it easier to handle
    16:   Mode 20 and Mode 21 ROMs.
    17: 
    18:   Todo (in no particular order):
    19:     - Emulate extra chips - superfx, dsp2, sa-1 etc.
    20:     - Add sound emulation. Currently the SPC700 is emulated, but that's it.
    21:     - Add horizontal mosaic, hi-res. interlaced etc to video emulation.
    22:     - Add support for fullgraphic mode(partially done).
    23:     - Fix support for Mode 7. (In Progress)
    24:     - Handle interleaved roms (maybe even multi-part roms, but how?)
    25:     - Add support for running at 3.58Mhz at the appropriate time.
    26:     - I'm sure there's lots more ...
    27: 
    28:     Nintendo Super System
    29: 
    30:   There is a second processor and Menu system for selecting the games
    31:   controlling timer etc.? which still needs emulating there are dipswitches too
