The Configuration dialog
-----------------------
TODO
The Configuration dialog
contains less-frequently-modified configuration options.
Most of these can be safely ignored,
or set once and never changed again.
The dialog has a tab for each main category of options:
- **Video**: This tab contains options that affect
how higan displays
the emulated console's video output.
- "Saturation" adjusts the vibrancy of colours displayed,
where 0% makes things pure grey,
100% is normal,
and 200% is garishly brightly coloured.
- "Gamma" adjusts how bright mid-range colours are
compared to the brightest colours,
where 100% is normal,
and 200% makes mid-range colours much darker.
- "Luminance" adjusts the overall brightness,
where 100% is normal,
and 0% is totally black.
- "Overscan Mask" controls the size of
the border drawn by the [Settings](#the-settings-menu)
→ Video Emulation
→ Mask Overscan option.
- **Audio**: This tab contains options that affect
how higan reproduces
the emulated console's audio output.
- "Latency" controls how much audio output higan calculates in advance.
Higher values reduce the chance of
"popping" or "glitching" noises,
but increase the delay between an action occurring on-screen
and the corresponding sound-effect being played.
- "Frequency" controls the sample-rate that higan will use
when generating audio.
If your PC's audio hardware has a "native" sample-rate
and you know what it is,
pick that.
Otherwise,
44.1kHz or 48kHz should be fine.
- "Resampler" selects the algorithm higan uses
to convert the console's native audio sample-rate
to the value selected for "Frequency" above.
- "Exclusive Mode" appears
if the current audio driver
allows higan to take exclusive control of your PC's audio output,
so no other applications can play sounds.
This can improve audio quality,
and lower the effective audio latency.
- "Volume" controls the overall loudness of
the emulated console's audio,
where 100% is normal volume,
and 0% is complete silence.
- "Balance" controls the relative loudness of
the left and right speakers,
where 0% means only the left speaker produces sound,
50% means both speakers produce sound equally,
and 100% means only the right speaker produces sound.
- "Reverb" adds a slight reverberation effect
to the emulated console's audio output,
as though the console were in a tunnel or small room.
- **Input**: This tab controls which PC inputs
are used for which emulated controllers.
The exact PC inputs that can be mapped
depend on [the input driver](#drivers).
- "Pause Emulation" automatically pauses emulation
when the main higan window
is not the current foreground window.
- "Allow Input" can be ticked
when "Pause Emulation" is *not* ticked,
and allows configured inputs to keep affecting higan
even when higan is running in the background.
This is particularly relevant if
you configure your PC keyboard to control higan:
if you tick this box,
and switch to a different application
leaving higan running in the background,
typing in that other application may affect
the emulated game running in higan
even though you can't see it!
- The console selector chooses which console's inputs
to display in the mapping list below.
- The port selector chooses which port of the selected console
to display in the mapping list below.
- The controller selector chooses which controller
associated with the given console and port
to display in the mapping list below.
- The mapping list includes
every button and axis on the selected controller,
and the PC inputs that are mapped to it
when it is connected to the selected port of the selected console.
- To map
a keyboard or gamepad button on your PC to
a controller button,
double-click the controller button in the list,
or select it and press Enter.
The window will grey out,
and a message will appear in the bottom left:
"Press a key or button to map [the button]".
Press the key or button you want to map,
and it should appear in the list
next to the controller button it is mapped to.
- To map
a mouse button on your PC to
a controller button,
select the controller button in the list,
then click one of the "Mouse Left",
"Mouse Middle",
or "Mouse Right" buttons in the bottom-left of the window.
- To map
a joystick axis on your PC to
a controller axis,
double-click the axis in the list,
or select it and press Enter.
The window will grey out,
and a message will appear in the bottom left:
"Press a key or button to map [the axis]".
Press the joystick in the direction you want to map,
and it should appear in the list
next to the controller button it is mapped to.
- To map
a mouse axis on your PC to
a controller axis,
select the axis in the list,
then click one of the
"Mouse X-axis",
or "Mouse Y-axis"
buttons in the bottom-left of the window.
- The "Rumble" setting
for the Game Boy Advance is treated like a button,
and can be mapped to a PC gamepad.
When the emulated Game Boy Advance
tries to use the rumble feature
of the Game Boy Player,
higan will turn on the force-feedback
of whatever gamepad the mapped button is part of.
- If you start mapping a button or axis,
but decide you don't want to,
you can press Escape
to exit the "Press a key or button to map..." mode
without actually mapping anything.
- "Erase" removes the mapping
for the selected button or axis.
- "Reset" removes all the mappings currently in the list.
- **Hotkeys**: This tab is like "Inputs" above,
except it contains controls for higan itself,
instead of for the emulated console.
- "Toggle Fullscreen" puts higan into fullscreen mode,
where the menu and status bar are hidden,
and the emulated console's video output
is enlarged to cover the entire screen.
Toggling fullscreen also automatically captures the mouse.
- "Toggle Mouse Capture" hides the usual mouse-cursor,
and captures the mouse so it cannot leave the higan window.
This is useful when the mouse is being used to emulate
a light-gun controller like the Super Scope.
- "Save State" saves the current state of the emulated console
to the "hotkey state" slot.
- "Load State" restores the emulated console
to the state saved in the "hotkey state" slot.
- "Pause Emulation" pauses the emulated console
until the Pause Emulation hotkey is pressed a second time.
- "Fast Forward" disables audio and video synchronisation
for as long as it's held down,
so emulation proceeds as quickly as possible.
If your PC struggles to hit "real time"
(60fps for most emulated consoles),
this likely won't have any effect.
- "Power Cycle" turns the emulated console off and back on,
(a "hard reset"),
just like the "Power Cycle" menu item
in [the console menu](#the-console-menu).
- "Rotate Display" will toggle the display
of the Game Boy Advance
and WonderSwan (Color)
between the usual landscape orientation
and a portrait orientation (90° counter-clockwise).
These consoles have games
that expect the player to hold the console
in a different way.
- **Advanced**: This tab contains all the settings
that didn't fit into one of the other categories.
Note that when changing a driver,
you must restart higan for the change to take effect.
- "Video" controls how higan will draw
the emulated console's video output
to the PC screen.
The best option is "OpenGL"
(since it allows you to use
[custom shaders](#installing-custom-shaders)),
and the safest is "Direct Draw" (for Windows)
or SDL (for Linux).
"None" means no video will be drawn.
- "Audio" controls how higan will present
the emulated console's audio output.
On Linux,
"PulseAudioSimple" is the most likely to work.
- "Input" controls how higan checks for input
from the PC's input devices.
On Linux,
"udev" is the most flexble,
but requires a modern Linux system,
while "Xlib" should work on other Unix-like OSs
but only supports a mouse and keyboard.
- "Location" selects where the [Game Library](#the-game-library)
looks for games to load.
This should be set to match icarus' library location.
- "Ignore Manifests" makes higan ignore the manifest file
in the a loaded game's [game folder](#why-game-folders)
in favour of asking icarus
to guess a manifest on the fly.
This means that incompatible or incorrect manifests
generated by old versions of icarus
won't cause problems,
but means you can't fix incorrect manifests
generated by the current version of icarus.
