/* tileattr rom

  this appears to be divided into 2 0x400 banks

  0x000 - 0x3ff relates to tiles 0x000-0x0ff

  0x400 - 0x7ff relates to tiles 0x100-0x1ff, 0x200-0x2ff, and 0x300-0x3ff

  every 2 tiles are somehow related to 8 bytes in the data

   so tiles 0x00 and 0x01 use bytes 0x000-0x007
            0x02                    0x008
            0x04                    0x010
            0x06                    0x018
            0x08                    0x020
            0x0a                    0x028
            0x0c                    0x030
            0x0e                    0x038
            0x10                    0x040
               .......
            0xfe and 0xff use bytes 0x3f8-0x3ff
            etc.

    it's probably some kind of lookup table for the colours (6bpp = 8 colours, maybe every 2 tiles share the same 8 colours)
    I guess either the bank (0/1) can be selected, or bank 0 is hardcoded to tiles 0x000-0x0ff (because tilemaps can use
     these tiles too, so it's not a case of it being a sprite/tilemap lookup split)

    anyway.. this is why the portraits logo is broken across 3 areas (0x1f2, 0x2f2, 0x3f2) so that they can share the same
    attributes from this rom
