/*

    T.S. 17.12.2005:

    Yamato:
    -------
     Added temporary bg gradient (bad colors/offset).

     Gradient table are stored in two(?) ROMs.
     Each table is 256 bytes long: 128 for normal
     and 128 bytes for flipped screen.
     Color format is unknown - probably direct RGB
     mapping of 8 or 16 (both roms) bits. Also table
     selection source is unknown.

     TODO:
      - bg gradient color decode & table selection


 Top Roller:
 ----------
     It's made by the same developers as Yamato and use
     probably the same encrypted SEGA cpu as Yamato.

     lives - $6155

     TODO:

       - COINB DSW is missing
       - few issues in cocktail mode
       - wrong colors (fg text layer) - game sometimes ("round" text , lives) updates only even columns of cell attribs...
