Tim Allen bab2ac812a Update to v101r24 release.

Changelog:

  - SMS: extended bus mapping of in/out ports: now decoding them fully
    inside ms/bus
  - SMS: moved Z80 disassembly code from processor/z80 to ms/cpu
    (cosmetic)
  - SMS: hooked up non-functional silent PSG sample generation, so I can
    cap the framerate at 60fps
  - SMS: hooked up the VDP main loop: 684 clocks/scanline, 262
    scanlines/frame (no PAL support yet)
  - SMS: emulated the VDP Vcounter and Hcounter polling ... hopefully
    it's right, as it's very bizarre
  - SMS: emulated VDP in/out ports (data read, data write, status read,
    control write, register write)
  - SMS: decoding and caching all VDP register flags (variable names
    will probably change)
  - nall: \#undef IN on Windows port (prevent compilation warning on
    processor/z80)

Watching Sonic the Hedgehog, I can definitely see some VDP register
writes going through, which is a good sign.

Probably the big thing that's needed before I can get enough into the
VDP to start showing graphics is interrupt support. And interrupts are
never fun to figure out :/

What really sucks on this front is I'm flying blind on the Z80 CPU core.
Without a working VDP, I can't run any Z80 test ROMs to look for CPU
bugs. And the CPU is certainly too buggy still to run said test ROM
anyway. I can't find any SMS emulators with trace logging from reset.
Such logs vastly accelerate tracking down CPU logic bugs, so without
them, it's going to take a lot longer.
