# DOSBox Staging (0.80.1) Config: 1984 IBM AT i80286 (6MHz)                    #
#------------------------------------------------------------------------------#
# Version:      1.0-2                                                          #

#------------------------------------------------------------------------------#
# Description:  Config file derived from a DBGL template to emulate a system   #
#               resembling an IBM AT with an i80286 running at 6MHz, 640KB     #
#               RAM, CGA graphics, and no sound card from around 1984.         #
#------------------------------------------------------------------------------#
# NOTES:      - I use the "pixellate" shader in the interpolation directory    #
#               available at https://github.com/tyrells/dosbox-svn-shaders.    #
#               You will either need to get it and place it in your            #
#               ~/.config/dosbox/glshaders directory (on Linux) or change the  #
#               "glshader" entry under "[render]" either to "none" or the      #
#               shader of your choosing.                                       #
#                                                                              #
#             - RAM is set to 1MB instead of 640KB due to DOSBox limitations.  #

[sdl]
#          fullscreen: Start directly in fullscreen.
#                      Run INTRO and see Special Keys for window control hotkeys.
#             display: Number of display to use; values depend on OS and user settings.
#      fullresolution: What resolution to use for fullscreen: 'original', 'desktop'
#                      or a fixed size (e.g. 1024x768).
#    windowresolution: Set window size when running in windowed mode:
#                        default:   Select the best option based on your
#                                   environment and other settings.
#                        small, medium, or large (or s, m, l):
#                                   Size the window relative to the desktop.
#                        <custom>:  Scale the window to the given dimensions in
#                                   WxH format. For example: 1024x768.
#                                   Scaling is not performed for output=surface.
# viewport_resolution: Set the viewport size (drawable area) within the window/screen:
#                        fit:       Fit the viewport to the available window/screen (default).
#                        <custom>:  Limit the viewport within to a custom resolution or percentage of
#                                   the desktop. Specified in WxH, N%, N.M%. Examples: 960x720 or 50%
#     window_position: Set initial window position when running in windowed mode:
#                        auto:      Let the window manager decide the position.
#                        <custom>:  Set window position in X,Y format. For example: 250,100
#                                   0,0 is the top-left corner of the screen.
#  window_decorations: Controls whether to display window decorations in windowed mode.
#        transparency: Set the transparency of the DOSBox Staging screen.
#                      From 0 (no transparency) to 90 (high transparency).
#           host_rate: Set the host's refresh rate:
#                        auto:      Use SDI rates, or VRR rates when fullscreen on a high-refresh
#                                   display.
#                        sdi:       Use serial device interface (SDI) rates, without further
#                                   adjustment.
#                        vrr:       Deduct 3 Hz from the reported rate (best-practice for VRR
#                                   displays).
#                        <custom>:  Specify a custom rate as a whole or decimal value greater than
#                                   23.000.
#               vsync: Synchronize with display refresh rate if supported. This can
#                      reduce flickering and tearing, but may also impact performance.
#          vsync_skip: Number of microseconds to allow rendering to block before skipping the next
#                      frame. 0 disables this and will always render.
#   presentation_mode: Optionally select the frame presentation mode:
#                        auto:  Intelligently time and drop frames to prevent
#                               emulation stalls, based on host and DOS frame rates.
#                        cfr:   Always present DOS frames at a constant frame rate.
#                        vfr:   Always present changed DOS frames at a variable frame rate.
#                      Possible values: auto, cfr, vfr.
#              output: What video system to use for output.
#                      Possible values: surface, texture, texturenb, texturepp, opengl, openglnb, openglpp.
#    texture_renderer: Choose a renderer driver when using a texture output mode.
#                      Use texture_renderer=auto for an automatic choice.
#                      Possible values: auto, opengl, opengles2, software.
#         waitonerror: Keep the console open if an error has occurred.
#            priority: Priority levels to apply when active and inactive, respectively. 
#                         auto:  Let the host operating system manage the priority (valid for both).
#                      Default is: 'auto auto'
#                      Possible values: auto, lowest, lower, normal, higher, highest.
#  mute_when_inactive: Mute the sound when the window is inactive.
# pause_when_inactive: Pause emulation when the window is inactive.
#          mapperfile: File used to load/save the key/event mappings.
#                      Pre-configured maps are bundled in the 'resources/mapperfiles' directory.
#                      They can be loaded by name, for example: mapperfile = xbox/xenon2.map
#                      Note: the -resetmapper commandline flag only deletes the default mapperfile.
#         screensaver: Use 'allow' or 'block' to override the SDL_VIDEO_ALLOW_SCREENSAVER
#                      environment variable (which usually blocks the OS screensaver
#                      while the emulator is running).
#                      Possible values: auto, allow, block.

#                            The 'resources/translations' directory bundled with the executable holds
#                            these files. Please keep it along-side the executable to support this
#                            feature.
#            machine: The type of machine DOSBox tries to emulate.
#                     Possible values: hercules, cga, cga_mono, tandy, pcjr, ega, vgaonly, svga_s3, svga_et3000, svga_et4000, svga_paradise, vesa_nolfb, vesa_oldvbe.
#           captures: Directory where things like wave, midi, screenshot get captured.
#            memsize: Amount of memory DOSBox has in megabytes.
#                     This value is best left at its default to avoid problems with some games,
#                     though few games might require a higher value.
#                     There is generally no speed advantage when raising this value.
# mcb_fault_strategy: How software-corrupted memory chain blocks should be handled:
#                       deny:    Quit (and report) when faults are detected (default).
#                       repair:  Repair (and report) faults using adjacent chain blocks.
#                       report:  Report faults but otherwise proceed as-is.
#                       allow:   Allow faults to go unreported (hardware behavior).
#                     The default (deny) is recommended unless a game is failing with MCB corruption
#                     errors.
#                     Possible values: deny, repair, report, allow.
#           vmemsize: Video memory in MiB (1-8) or KiB (256 to 8192). 'auto' uses the default per
#                     video adapter.
#                     Possible values: auto, 1, 2, 4, 8, 256, 512, 1024, 2048, 4096, 8192.
#           dos_rate: Customize the emulated video mode's frame rate, in Hz:
#                     default:  The DOS video mode determines the rate (recommended).
#                     host:     Match the DOS rate to the host rate (see 'host_rate' setting).
#                     <value>:  Sets the rate to an exact value, between 24.000 and 1000.000 (Hz).
#                     We recommend the 'default' rate; otherwise test and set on a per-game basis.
#         vesa_modes: Controls the selection of VESA 1.2 and 2.0 modes offered:
#                       compatible   A tailored selection that maximizes game compatibility.
#                                    This is recommended along with 4 or 8 MB of video memory.
#                       halfline     Supports the low-resolution halfline VESA 2.0 mode used by
#                                    Extreme Assault. Use only if needed, as it's not S3 compatible.
#                       all          Offers all modes for a given video memory size, however
#                                    some games may not use them properly (flickering) or may need
#                                    more system memory (mem = ) to use them.
#                     Possible values: compatible, all, halfline.
#         speed_mods: Permit changes known to improve performance. Currently no games are known
#                     to be affected by this. Please file a bug with the project if you find a
#                     game that fails when this is set to true so we will list them here.
#   autoexec_section: How autoexec sections are handled from multiple config files.
#                     join      : combines them into one big section (legacy behavior).
#                     overwrite : use the last one encountered, like other conf settings.
#                     Possible values: join, overwrite.
#          automount: Mounts 'drives/[c]' directories as drives on startup, where [c] is
#                     a lower-case drive letter from a to y.  The 'drives' folder can be
#                     provided relative to the current directory or via built-in resources.
#                     Mount settings can be optionally provided using a [c].conf file along-
#                     -side the drive's directory, with content as follows:
#                       [drive]
#                       type    = dir, overlay, floppy, or cdrom

#                       override_drive = mount the directory to this drive instead (default empty)
#                       verbose = true or false
#  startup_verbosity: Controls verbosity prior to displaying the program:
#                     Verbosity   | Welcome | Early stdout
#                     high        |   yes   |    yes

#                     auto        | 'low' if exec or dir is passed, otherwise 'high'
#                     Possible values: auto, high, low, quiet.

#             aspect: Scales the vertical resolution to produce a 4:3 display aspect
#                     ratio, matching that of the original standard-definition monitors
#                     for which the majority of DOS games were designed. This setting
#                     only affects video modes that use non-square pixels, such as
#                     320x200 or 640x400; where as square-pixel modes, such as 640x480
#                     and 800x600, will be displayed as-is.
# monochrome_palette: Select default palette for monochrome display.
#                     Works only when emulating hercules or cga_mono.
#                     You can also cycle through available colours using F11.
#                     Possible values: white, paperwhite, green, amber.
#         cga_colors: Sets the interpretation of CGA RGBI colors. Affects all machine types capable
#                     of displaying CGA or better graphics. Built-in presets:
#                       default:       The canonical CGA palette, as emulated by VGA adapters
#                                      (default).
#                       tandy [BL]:    Emulation of an idealised Tandy monitor with adjustable
#                                      brown level. The brown level can be provided as an optional
#                                      second parameter (0 - red, 50 - brown, 100 - dark yellow;
#                                      defaults to 50). E.g. tandy 100
#                       tandy-warm:    Emulation of the actual color output of an unknown Tandy
#                                      monitor.
#                       ibm5153 [C]:   Emulation of the actual color output of an IBM 5153 monitor
#                                      with a unique contrast control that dims non-bright colors
#                                      only. The contrast can be optionally provided as a second
#                                      parameter (0 to 100; defaults to 100), e.g. ibm5153 60

#                                      contrast.
#                     You can also set custom colors by specifying 16 space or comma separated color
#                     values, either as 3 or 6-digit hex codes (e.g. #f00 or #ff0000 for full red),
#                     or decimal RGB triplets (e.g. (255, 0, 255) for magenta). The 16 colors are
#                     ordered as follows:
#                     black, blue, green, cyan, red, magenta, brown, light-grey, dark-grey,

#                     command-line argument, or an absolute or relative path to a file.
#                     In all cases, you may omit the shader's '.glsl' file extension.

#              Possible values: auto, on, off.
#         era: Era of composite technology. When 'auto', PCjr uses new and CGA/Tandy use old.
#              Possible values: auto, old, new.

#    cycles: Number of instructions DOSBox tries to emulate each millisecond.
#            Setting this value too high results in sound dropouts and lags.
#            Cycles can be set in 3 ways:
#              'auto'          tries to guess what a game needs.
#                              It usually works, but can fail for certain games.
#              'fixed #number' will set a fixed number of cycles. This is what you usually
#                              need if 'auto' fails (Example: fixed 4000).
#              'max'           will allocate as much cycles as your computer is able to
#                              handle.
#            Possible values: auto, fixed, max.
#   cycleup: Number of cycles added or subtracted with speed control hotkeys.
#            Run INTRO and see Special Keys for list of hotkeys.

#                         onstart:   Capture the mouse immediately on start. Might not work correctly
#                                    on some host operating systems.
#                         seamless:  Let the mouse move seamlessly; captures only with middle-click or
#                                    hotkey. Seamless mouse does not work correctly with all the games,
#                                    Windows 3.1x can be made compatible with a custom mouse driver.
#                         nomouse:   Hide the mouse and don't send input to the game.
#                       For touchscreen control use the seamless method.
#                       
#                       Possible values: seamless, onclick, onstart, nomouse.
# mouse_middle_release: If true, middle-click will release the captured mouse, and also
#                       capture when seamless.
#    mouse_sensitivity: Default mouse sensitivity. 100 is a base value, 150 is 150% sensitivity, etc.
#                       Negative values reverse mouse direction, 0 disables the movement completely.
#                       The optional second parameter specifies vertical sensitivity (e.g. 100,200).
#                       Setting can be adjusted in runtime (also per mouse interface) using internal
#                       MOUSECTL.COM tool, available on drive Z:.
#      mouse_raw_input: Enable to bypass your operating system's mouse acceleration and sensitivity
#                       settings. Works in fullscreen or when the mouse is captured in window mode.
#     dos_mouse_driver: Enable built-in DOS mouse driver.
#                       Notes:
#                          Disable if you intend to use original MOUSE.COM driver in emulated DOS.
#                          When guest OS is booted, built-in driver gets disabled automatically.
#  dos_mouse_immediate: Updates mouse movement counters immediately, without waiting for interrupt.
#                       May improve gameplay, especially in fast paced games (arcade, FPS, etc.) - as
#                       for some games it effectively boosts the mouse sampling rate to 1000 Hz, without
#                       increasing interrupt overhead.
#                       Might cause compatibility issues. List of known incompatible games:

#  blocksize: Mixer block size; larger values might help with sound stuttering but sound will
#             also be more lagged.
#             Possible values: 128, 256, 512, 1024, 2048, 4096, 8192.
#  prebuffer: How many milliseconds of sound to render on top of the blocksize; larger values
#             might help with sound stuttering but sound will also be more lagged.
#  negotiate: Let the system audio driver negotiate (possibly) better rate and blocksize
#             settings.
# compressor: Enable the auto-leveling compressor on the master channel to prevent clipping
#             of the audio output:
#               off:  Disable compressor.
#               on:   Enable compressor (default).
#  crossfeed: Set crossfeed globally on all stereo channels for headphone listening:
#               off:         No crossfeed (default).
#               on:          Enable crossfeed (at strength 40).
#               <strength>:  Set crossfeed strength from 0 to 100, where 0 means no crossfeed
#                            (off) and 100 full crossfeed (effectively turning stereo content
#                            into mono).
#             Note: You can set per-channel crossfeed via mixer commands.
#     reverb: Enable reverb globally to add a sense of space to the sound:
#               off:     No reverb (default).
#               on:      Enable reverb (medium preset).
#               tiny:    Simulates the sound of a small integrated speaker in a room;
#                        specifically designed for small-speaker audio systems
#                        (PC Speaker, Tandy, PS/1 Audio, and LPT DAC devices).
#               small:   Adds a subtle sense of space; good for games that use a single
#                        synth channel (typically OPL) for both music and sound effects.
#               medium:  Medium room preset that works well with a wide variety of games.
#               large:   Large hall preset recommended for games that use separate
#                        channels for music and digital audio.
#               huge:    A stronger variant of the large hall preset; works really well
#                        in some games with more atmospheric soundtracks.
#             Note: You can fine-tune per-channel reverb levels via mixer commands.
#             Possible values: off, on, tiny, small, medium, large, huge.
#     chorus: Enable chorus globally to add a sense of stereo movement to the sound:

#               normal:  Normal chorus that works well with a wide variety of games.
#               strong:  An obvious and upfront chorus effect.
#             Note: You can fine-tune per-channel chorus levels via mixer commands.

[midi]
# mididevice: Device that will receive the MIDI data (from the emulated MIDI
#             interface - MPU-401). Choose one of the following:
#             'fluidsynth', to use the built-in MIDI synthesizer. See the
#                    [fluidsynth] section for detailed configuration.
#             'mt32', to use the built-in Roland MT-32 synthesizer.
#                    See the [mt32] section for detailed configuration.
#             'auto', to use the first working external MIDI player. This
#                    might be a software synthesizer or physical device.
#             Possible values: auto, oss, alsa, fluidsynth, mt32, none.
# midiconfig: Configuration options for the selected MIDI interface.
#             This is usually the id or name of the MIDI synthesizer you want
#             to use (find the id/name with DOS command 'mixer /listmidi').
#             - This option has no effect when using the built-in synthesizers
#               (mididevice = fluidsynth or mt32).
#             - When using ALSA, use Linux command 'aconnect -l' to list open
#               MIDI ports, and select one (for example 'midiconfig=14:0'
#               for sequencer client 14, port 0).
#             - If you're using a physical Roland MT-32 with revision 0 PCB,
#               the hardware may require a delay in order to prevent its
#               buffer from overflowing. In that case, add 'delaysysex',
#               for example: 'midiconfig=2 delaysysex'.
#             See the README/Manual for more details.
#     mpu401: Type of MPU-401 to emulate.
#             Possible values: intelligent, uart, none.

[fluidsynth]
#     soundfont: Path to a SoundFont file in .sf2 format. You can use an
#                absolute or relative path, or the name of an .sf2 inside
#                the 'soundfonts' directory within your DOSBox configuration
#                directory.
#                Note: The optional volume scaling percentage after the filename
#                has been deprecated. Please use a mixer command instead to
#                change the FluidSynth audio channel's volume, e.g.:
#                  MIXER FSYNTH 200
# fsynth_chorus: Chorus effect: 'auto', 'on', 'off', or custom values.
#                When using custom values:
#                  All five must be provided in-order and space-separated.
#                  They are: voice-count level speed depth modulation-wave, where:
#                  - voice-count is an integer from 0 to 99.
#                  - level is a decimal from 0.0 to 10.0
#                  - speed is a decimal, measured in Hz, from 0.1 to 5.0
#                  - depth is a decimal from 0.0 to 21.0
#                  - modulation-wave is either 'sine' or 'triangle'
#                  For example: chorus = 3 1.2 0.3 8.0 sine
#                Note: You can disable the FluidSynth chorus and enable the
#                mixer-level chorus on the FluidSynth channel instead, or
#                enable both chorus effects at the same time. Whether this
#                sounds good depends on the SoundFont and the chorus settings
#                being used.
# fsynth_reverb: Reverb effect: 'auto', 'on', 'off', or custom values.
#                When using custom values:
#                  All four must be provided in-order and space-separated.
#                  They are: room-size damping width level, where:
#                  - room-size is a decimal from 0.0 to 1.0
#                  - damping is a decimal from 0.0 to 1.0
#                  - width is a decimal from 0.0 to 100.0
#                  - level is a decimal from 0.0 to 1.0
#                  For example: reverb = 0.61 0.23 0.76 0.56
#                Note: You can disable the FluidSynth reverb and enable the
#                mixer-level reverb on the FluidSynth channel instead, or
#                enable both reverb effects at the same time. Whether this
#                sounds good depends on the SoundFont and the reverb settings
#                being used.
# fsynth_filter: Filter for the FluidSynth audio output:

#                    network (using libslirp) with properties as follows:
#                     - 255.255.255.0 : Subnet mask of the 10.0.2.0 virtual LAN.
#                     - 10.0.2.2      : IP of the gateway and DHCP service.
#                     - 10.0.2.3      : IP of the virtual DNS server.
#                     - 10.0.2.15     : First IP provided by DHCP, your IP!
#                    Note: Inside DOS, setting this up requires an NE2000 packet driver,
#                          DHCP client, and TCP/IP stack. You might need port-forwarding
#                          from the host into the DOS guest, and from your router to your
#                          host when acting as the server for multiplayer games.
#           nicbase: The base address of the NE2000 card.
#                    Note: Addresses 220 and 240 might not be available as they're assigned
#                          to the Sound Blaster and Gravis UltraSound by default.
#                    Possible values: 200, 220, 240, 260, 280, 2c0, 300, 320, 340, 360.
#            nicirq: The interrupt used by the NE2000 card.
#                    Note: IRQs 3 and 5 might not be available as they're assigned
#                          to 'serial2' and the Gravis UltraSound by default.
#                    Possible values: 3, 4, 5, 9, 10, 11, 12, 14, 15.
#           macaddr: The MAC address of the NE2000 card.
# tcp_port_forwards: Forwards one or more TCP ports from the host into the DOS guest.
#                    The format is:
#                      port1  port2  port3 ... (e.g., 21 80 443)
#                      This will forward FTP, HTTP, and HTTPS into the DOS guest.
#                    If the ports are privileged on the host, a mapping can be used
#                      host:guest  ..., (e.g., 8021:21 8080:80)
#                      This will forward ports 8021 and 8080 to FTP and HTTP in the guest
#                    A range of adjacent ports can be abbreviated with a dash:
#                      start-end ... (e.g., 27910-27960)
#                      This will forward ports 27910 to 27960 into the DOS guest.
#                    Mappings and ranges can be combined, too:
#                      hstart-hend:gstart-gend ..., (e.g, 8040-8080:20-60)
#                      This forwards ports 8040 to 8080 into 20 to 60 in the guest
#                    Notes:
#                      - If mapped ranges differ, the shorter range is extended to fit.
#                      - If conflicting host ports are given, only the first one is setup.
#                      - If conflicting guest ports are given, the latter rule takes precedent.
# udp_port_forwards: Forwards one or more UDP ports from the host into the DOS guest.
#                    The format is the same as for TCP port forwards.
