  A. Internals
  ------------
    CPU     - Central Processing Unit: Self-explanitory. The NES uses a
              standard 6502 (NMOS).
    PPU     - Picture Processing Unit: Used to control graphics, sprites,
              and other video-oriented features.
    pAPU    - pseuedo-Audio Processing Unit: Native to the CPU; generates
              waveforms via (5) audio channels:: four (4) analogue, and
              one (1) digital. There is no physical IC for audio process-
              ing nor generation inside the NES.
    MMC     - Multi-Memory Controller: Micro-controllers used in NES games
              to access memory beyond the 6502 64Kbyte boundary. They can
              also be used to access extra CHR-ROM, and may be used for
              "special effects" such as forcing and IRQ, and other things.
    VRAM    - Video RAM: The RAM which is internal to the PPU. There is
              16kbits of VRAM installed in the NES.
    SPR-RAM - Sprite RAM: 256 bytes of RAM which is used for sprites. It is
              not part of VRAM nor ROM, though it's local to the PPU.
    PRG-ROM - Program ROM: The actual program-code area of memory. Also can
              be used to describe areas of code which are external to the
              actual code area and are swapped in via an MMC.
    PRG-RAM - Program RAM: Synonymous with PRG-ROM, except that it's RAM.
    CHR-ROM - Character ROM: The VRAM data which is kept external to the PPU,
              swapped in and out via an MMC, or "loaded" into VRAM during the
              power-on sequence.
    VROM    - Synonymous with CHR-ROM.
    SRAM    - Save RAM: RAM which is commonly used in RPGs such as "Cry-
              stalis," the Final Fantasy series, and "The Legend of Zelda."
    WRAM    - Synonymous with SRAM.
    DMC     - Delta Modulation Channel: The channel of the APU which handles
              digital data. Commonly referred to as the PCM (Pulse Code
              Modulation) channel.
    EX-RAM  - Expansion RAM: This is the memory used within Nintendo's MMC5,
              allowing games to extend the capabilities of VRAM.


  B. Hardware
  -----------
    NES     - Nintendo Entertainment System: Self-explanitory.
    Dandy   - Synonymous (hardware-wise) with the Famicom.
    Famicom - Synonymous with the NES, except for not supporting the RAW
              method of DMC digital audio playback.
    FDS     - Famicom Disk System: Unit which sits atop the Famicom, support-
              ing the use of 3" double-sided floppy disks for games.
