          Second column: shows the mode type
              ModeQ - A tweaked VGA video mode. Supports 256x256 resolution
                and 256 colors. Accesses hardware directly.
              ModeX - A different tweaked VGA video mode, similar to ModeQ,
                although slower. Accesses hardware directly.
              Vesa1 - VESA ("Video Electronic Standards Association") VBE
                ("Video BIOS Extension") 1.2. A standardized method of
                accessing VGA cards.
              Vesa2 - VESA VBE 2. Faster and more features than VESA1.
                Read the Wikipedia article for an overview
                [http://en.wikipedia.org/wiki/VESA_BIOS_Extensions].
                The first [http://www.ddj.com/184409592] and third
                [http://www.faqs.org/faqs/pc-hardware-faq/supervga-programming/]
                external links from that article provide some more detailed
                information.
      Your video card may be compatible with only some of the video modes
        listed. You should try each video mode to find the right combination
        of speed, compatibility, and enhancement features (listed below).
  Set button - use the currently selected/highlighted video mode. ZSNES will now
    attempt to change to the new video mode. If the new video mode does not
    work, wait for ten seconds without pressing any keys, and ZSNES will return
    to the previous mode. Pressing Enter does the same thing as the Set button.
  Custom: (Win/SDL only) - use in conjunction with one of the custom
    video modes at the bottom of the list to set a custom resolution.
        Set button - save the current custom resolution.
        Type in the custom width and height, respectively, in pixels,
          in the two black boxes.
  Current: - shows the current video mode.

  Note: Some video modes may work better / faster than others, depending
    on your system configuration. Play around to see what's best.

  Filters tab

  Video Filters: - Choose one video filter. You must use a D video mode
    to use any of these filters. Furthermore, filters marked with a *
    require MMX Support.
      Interpolation - Enable interpolation, a simple filter that smooths the
        image and makes it appear less pixellated. This is software-driven and
        can be accelerated with MMX support.
      Bilinear Filter [http://wiki.beyondunreal.com/wiki/Bilinear_Filtering]
        (OpenGL modes only) - This produces an effect similar to Interpolation.
        The option replaces Interpolation and, as long as you aren't using Mesa
        [http://www.mesa3d.org], is hardware-driven. This means that as long as
        you aren't using Mesa, it requires less CPU overhead. Another advantage
        of the bilinear filter is that it can also be used alongside the other
        filters, though this may be slow.
      NTSC [http://www.slack.net/~ant/libs/ntsc.html] (Win/SDL only) -
        Written by blargg. It is recommended to use a video mode with at least
        602x448 resolution. Makes the video output appear to be that of an NTSC
        CRT [http://en.wikipedia.org/wiki/Cathode_ray_tube] television
        [http://en.wikipedia.org/wiki/Ntsc]. This filter is not available
        in the SDL port while using OpenGL modes.
      2xSaI Engine* [http://elektron.its.tudelft.nl/~dalikifa/] - Written by
        Kreed. SaI stands for "Scale and Interpolation." This is a "smart"
        filter that tries to make a lo-res image (like SNES video output)
        appear to have a higher resolution. The image should look smoother,
        less blocky, when using this filter.
      Super Eagle* - Written by Kreed. Similar to the 2XSaI engine, but
        does more blending.
      Super 2xSaI* - Written by Kreed. This filter smoothes the graphics,
        but it blends more than the Super Eagle engine.
      HQ2X* [http://www.hiend3d.com/hq2x.html] (Win/SDL only) - Written by
        MaxSt. Applies an advanced algorithm to smooth the appearance of a
        low-resolution image. It is recommended to use a 2x scaled image with
        this filter.
      HQ3X* [http://www.hiend3d.com/hq3x.html] (Win only) - Written by MaxSt.
        More advanced than HQ2X, and it is recommended to use a 3x scaled image
        with this filter.
      HQ4X* [http://www.hiend3d.com/hq4x.html] (Win only) - Written by MaxSt.
        More advanced than HQ3X, and it is recommended to use a 4x scaled image
        with this filter.
      Note: The HQxX filters and the NTSC filter have particularly high
        system requirements to run smoothly.
  Scanlines: - Choose one Scanline mode. Requires a 'D' video mode.
      None - This will disable scanlines.
      25% - This will enable scanline mode, except that each line is 25% darker
        than the line above it.
      50% - This will enable scanline mode, except that each line is 50% darker
        than the line above it.
      Full - This mode adds a blank line in between every line to produce
        a scanline effect similar to a TV.
  Misc Filters: - Choose miscellaneous filters.
      Grayscale Mode - Makes the game display in monochrome color, i.e.
        black and white. This option is just there for fun and is probably not
        something you want to use continuously.
      Hi-Res Mode 7 - Requires a 'D' video mode and at least 512x448 resolution.
        Enabling this will double the vertical resolution used when rendering
        Mode 7 graphics. Thus, the resolution becomes 256*448 rather than the
        normal 256*224.
  Monitor Sync: - Select monitor synchronization options.
      VSync (Win/DOS only) - Synchronizes frame drawing to the monitor's
        refresh rate. This may reduce frame rate on your computer, but will
        reduce screen tearing.
      Triple Buffering (Win/DOS only) - This setting is only visible while
        using a fullscreen video mode, and only applies while in fullscreen.
        Whereas VSync has only two frame buffers: the frame being drawn and
        the frame waiting to draw, Triple Buffering can write frame data to
        a third buffer. The primary use is to reduce the impact of VSync on
        slower systems. This option has precedence over VSync in Fullscreen
        modes.
  Display Options: - Select how you want the image to be displayed.
      Use 4:3 Ratio (Win/SDL only) - This only applies when using a custom mode.
        Using this option will lock the video output at 4:3 aspect ratio,
        regardless of the aspect ratio of the custom resolution you've chosen.
      Small Screen (DOS only) - Video output will be at 256x224 (the native
        internal resolution of the SNES), instead of whatever resolution
        you are using.
      Full Screen / Wide Screen (DOS only) - Horizontally stretches video output
        to fill the screen.
  Not all of the video options above are available in every video mode
    and every port of ZSNES. Also note that you will need a fast computer
    for some of them if you don't want to see any slow-downs in emulation.

 .               Sound               .
- - - - - - - - - - - - - - - - - - - -

  Configure various sound settings here.

  The default settings are those that are most accurate to a Super Nintendo.

  Sound Switches:
      Disable SPC Emulation - Disables the emulation of the SPC700 chip.
        Do not disable this unless you are having severe performance issues
        (i.e. ZSNES is unacceptably slow and you've tried everything else).
        Disabling this will likely result in sound errors.
      Enable Sound - Default: Checked. Unchecking this disables sound output.
        Do not disable this unless you are having severe performance issues
        (i.e. ZSNES is unacceptably slow and you've tried everything else).
        If you wish to mute ZSNES, just move the volume slider down to 0%.
      Enable Stereo Sound - Default: Checked. Unchecking this will disable
        *stereo* sound output; thus, sound output will be mono instead.
        Disabling this is a relatively safe way to improve speed, if necessary.
      Reverse Stereo Channels - Reverse/swap the left and right stereo channels.
        This makes no difference if stereo sound is disabled.
      Simulate Surround Sound - This is a novelty feature that simulates
        surround sound in games that don't have it natively. Do *not* use this
        in conjunction with games that have native surround sound. This option
        is only available when stereo sound is enabled.
      Force 8-bit Output (DOS only) - Force ZSNES to output sound in 8-bit mode.
        Using this may work around problems with certain sound cards, but will
        reduce sound quality. Note that if you use stereo sound in addition to
        this option, you will not be able to use sampling rates above 22050Hz.
      Use Primary Buffer (Win only) - Enable this only if your sound card is
        having problems designating the sound buffer with DirectSound. This will
        prevent sharing the sound card with other programs. This option is
        primarily useful for troubleshooting in Win9x. You must restart ZSNES
        for this feature to take effect.
  Sampling Rate: - Default: 32000Hz. Click inside the black box to cycle through
    all available sampling rates. Note that if you use sampling rates that are
    below the default, the sound will be distorted and inaccurate. Sampling
    rates higher than 32000Hz can also cause problems; however, sampling rates
    of 41000Hz and higher may resolve crackling issues that occur with some
    onboard sound cards.
  Volume Level - To change, just slide the bar. Sliding this to 0% is a better
    method of muting sound output than unchecking the Enable Sound box.
  Interpolation: - This feature smoothes out the wave forms of lower frequency
    sounds.
        None - Use no interpolation. This is *not* accurate to the SNES!
        Gaussian - Default. Based on the Gaussian curve, it smoothes the
          transition of the sound effects. This method of interpolation is used
          by a real SNES.
        Cubic Spline - This method is calculated by a cubic equation rather than
          being based on a curve like the Gaussian method. This results in
          better approximation than the Gaussian method.
        8-point* - Takes 8 points on the sound curve and smoothes them out.
  LowPass: - Low-pass filters accentuate bass frequencies by reducing higher
    frequencies. None of these filters are native to the SNES; if you want
    authentic SNES sound, do not use any of these. Using a filter will probably
    be most noticeable if you have a subwoofer.
        None - Use no low-pass filter.
        Simple - Allows lower frequencies to pass through (e.g. drums and
          the like). Certain higher ranges are not heard though.
        Dynamic - Allows greater range of frequencies to pass through;
          the music will seem more detailed depending on the loudness or
          softness of the audio.
        Hi Quality* - It's better than the simple filter, and seems to work well
          with lower quality speakers that have decent sound cards.
  *Requires MMX Support.

  Set and change paths used for save directories, graphics packs, and base
  cartridges.

  Saves: - Configure the directory where ZSNES will save and load SRAM, save
    state, and ZMV files. If you do not specify a path here, ZSNES Win and DOS
    will save all files to the same directory as the currently loaded ROM.
    ZSNES SDL will place them in "~/.zsnes". ZSNES SDL under Mac OS X will place
    them in "~/Library/Application Support/ZSNES".
  Snapshots: - Configure the directory to which in-game snapshots will be saved.
    If you do not specify a path here, snapshots will be saved to your Saves
    directory (above).
  SPCs: - Configure the directory to which SPC700 sound dumps (.spc; SNES
    music files) and sound buffer dumps will be saved. If you do not specify
    a path here, these files will be saved to your Saves directory (above).
  BIOS/Base Carts - Set the path to BIOS and base cartridges of various
    special games.
        BS-X: - Specify the full path and filename to the Broadcast Satellaview
          BIOS. Currently, the BIOS is *not* required to run BS games.
        Sufami Turbo - Specify the full path and filename to the Sufami Turbo
