    Namco (Super) System 23
    Extremely preliminary driver by R. Belmont, thanks to Phil Stroffolino & Olivier Galibert

    Hardware: R4650 (MIPS III with IDT special instructions) main CPU @ 166 MHz
              H8/3002 MCU for sound/inputs
          Custom polygon hardware
      1 text tilemap
          Sprites?

    NOTES:
    - First 128k of main program ROM is the BIOS, and after that is a 64-bit MIPS ELF image.

    - Text layer is (almost?) identical to System 22 & Super System 22.

    TODO:
    - Text layer does not refresh properly in all cases, in spite of forced all-dirty.
      Why?

    - Palette is not right.  Games always write 16 bits at a time where the top 8 bits of each 16
      appear to always be 0 (some sort of gamma correct?).

    - H8/3002 does not handshake.  Protocol should be the same as System 12 where the MIPS
      writes 0x3163 to offset 0x3002 in the shared RAM and the H8/3002 notices and sets it to 0x7106.
      The H8 currently never reads that location (core bug?).

    - Hook up actual inputs via the 2 serial latches at d00004 and d00006.
      Works like this: write to d00004, then read d00004 12 times.  Ditto at
      d00006.  This gives 24 bits of inputs from the I/O board (?).

    - The entire 3D subsystem.  Is there a DSP living down there?  If not, why the 300k
      download on initial startup?

    - There are currently no differences seen between System 23 (Time Crisis 2) and
      Super System 23 (GP500, Final Furlong 2).  These will presumably appear when
      the 3D hardware is emulated.

    - Serial number data is at offset 0x201 in the BIOS.  Until the games are running
      and displaying it I'm not going to meddle with it though.
