`-cartdrige', `-cart', ...

In Linux and Mac OS X you can also use `--' before options instead of `-'.
In DOS and Windows you can also use `/'.


5 FEATURES
==========

This section contains a brief description of all the features
of AdvanceMAME.

5.1 Automatic Video Mode Generation
-----------------------------------

AdvanceMAME has the ability to directly control your video
board to get the best possible video modes with always the
correct size and aspect ratio.

You can control how the video modes are generated with the
`display_adjust' option. More details are in the `install.txt'
file.

5.2 Video Menu
--------------

AdvanceMAME adds a new `Video' menu in MAME to change the video
options.

You can select the desired video mode, the resize type and the
video effects.

The selected option is displayed at the right side of the menu,
the effective value used for the option is displayed in `[]'.

5.3 Resize
----------

AdvanceMAME supports many software stretching types of the
game image. Generally they are not used, because a video
mode of the correct size is automatically generated.
But in some conditions it isn't possible, in this case the
image is stretched.

There are four stretch types: `none', `integer', `mixed', `fractional'.
You can control the type of stretching with the `display_resize' option.

The `none' option simply disables any type of stretching.
The `integer' option allows only integer stretching in the
horizontal and vertical directions. For example 1x2, 2x1, 2x2.
The `mixed' option allows integer stretching in the horizontal
direction and fractional stretching in the vertical direction.
For example 1x1.23, 2x1.18.
The `fractional' option allows fractional stretching in any
directions. For example 1.08x1.08, 1.34x1.78.

Usually the best choice is the `mixed' option. It's very fast
and the image quality doesn't suffer too much.

5.4 Blit Effects
----------------

AdvanceMAME supports many special video effects to improve
the image quality when it's stretched.

There are a lot of video effects: `none', `max', `mean',
`filter', `scale', `lq' and `hq'.
You can select the favorite effect with the `display_resizeeffect'
option.

The `none' effect simply duplicates and removes rows and lines
when the image is stretched.
The `max' effect tries to save the image details checking the luminosity
of the pixels in stretching. It ensures to have vertical and horizontal lines
always of the same thickness.
The `mean' effect tries to save the image details displaying the
mean color of the pixels in stretching.
The `filter' effect applies a generic blur filter computing the
mean color in the horizontal and vertical directions. The best
results are when the image is stretched almost by a double
factor. When the image is enlarged the filter is applied after
stretching; when reduced, it's applied before.
The `scale', `lq' and `hq' effects add missing pixels
trying to match the image patterns.

The `mean' and `filter' effects work only in RGB video
modes (not palettized).

The `scale', `lq' and `hq' effects work only if the image is
magnified. To enable it you should also use the `magnify' option.

5.5 RGB Effects
---------------

AdvanceMAME supports also some special video effects to simulate
the aspect of the game as displayed in an old fashion Arcade
Monitor.

You can simulate the RGB triads of the screen or the vertical and
horizontal scanlines.

5.6 Mode Selection
------------------

In the `Video Mode' submenu you can select the favorite video
mode.

If you choose `auto', the best video mode is chosen
automatically.

You can change the active video mode pressing `,' and `.' when
in game play.

You can force a specific video mode with the option
`display_mode'.

5.7 Per game/resolution/frequency/orientation options
-----------------------------------------------------

All the options are customizable in the configuration file for
the single game or for a subset of games defined by the game
resolution, frequency and orientation.

5.8 Scripts
-----------

AdvanceMAME supports a basic script language capable to
control an external hardware through the parallel port
or keyboard led signals.

More details are in the `script.txt' file.

5.9 Aspect Ratio Control
------------------------

AdvanceMAME tries always to display the game with the
correct aspect ratio.

But if you want, you can permit a small aspect error
to enlarge the effective game image on the screen.
It's very useful to display vertical games on
horizontal monitors and vice versa.

More details are in the description of the `display_expand'
option.

5.10 Speed Control
------------------

AdvanceMAME permits a special speed control of the game
play.

You can play the game in a faster way, change arbitrarily the
frame rate, skip the game startup process at the maximum speed,
or skip the game animations pressing a key.

Press `asterisk_pad' to enable the `turbo' mode. Press `minus_pad'
to mark the time of the real game start. The next time the game is
started, it will execute very fast until this time.

More details are in the description of the `sync_fps', `sync_speed',
`sync_turbospeed' and `sync_startuptime' options.

The video and audio synchronization uses an advanced algorithm,
which ensure always the best performance.

The program continuously measures the time required to compute a
frame and continuously adapt the number of frame to skip and
to draw.

If it detects that you have system too slow to play the game
at full speed, it automatically disables any frame skipping.

If the underline Operand System allows that, AdvanceMAME release
the CPU when it isn't used after computing each frame reducing the
CPU occupation. For example this happen on Linux 2.6 which has a
3ms delay granularity, but not in Linux 2.4 which has a 20ms
granularity.

5.11 Audio Control
------------------

The audio volume is automatically adjusted to ensure
that all the emulated games have the same volume power.

An equalizer and a spectrum analyzer are also available.

More details are in the description of the `sound_normalize'
and `sound_equalizer' options.

5.12 Exit Control
-----------------

If you have a real Arcade Cabinet you can configure AdvanceMAME
to automatically exit after some time of inactivity to save
your monitor screen.

For some supported games you can force the display of an
exit menu during the game play to prevent unwanted exit.

More details are in the description of the `misc_safequit',
and `input_idleexit' options.

5.13 Input Control
------------------

AdvanceMAME supports a very fine control of the mapping
of the analog and digital inputs. You can remap any input
event using easy to maintain text configuration files.

More details are in the description of the `input_map'
option.

5.14 Audio and Video Recording
------------------------------

AdvanceMAME can saves the game play in .WAV audio files and
.MNG video files.

More details are in the description of the `record_*'
options.

5.15 User Interface
-------------------

AdvanceMAME displays the user interface directly on the screen
instead on the game image.

This means that the interface doesn't have applied the same video
effects of the game, it isn't limited on the game area, it
isn't recorded on video clips and you can customize the font.

Also, True Type fonts with alpha blending are supported.

More details are in the description of the `ui_*' options.

5.16 Input Help
---------------

AdvanceMAME is able to display a help image containing the
input mapping of the emulated game. Any input element has a
different depending on the assigned player and if it's pressed
or not.

The default image is a standard keyboard, with the used keys
highlighted. If you have an Arcade cabinet you can create your
personalized control image and select each region to highlight.

Press `f1' on the game play to display it.

More details are in the description of the `ui_help*' options.

5.17 Input Text Configuration File
----------------------------------

All the user customizations are stored in a single textual
configuration file and not in a lot of .cfg file like other MAME ports.

This allows to view, edit and copy any customization manually.
They are also more compact because only the difference from the
default is saved.

They are independent of the internal MAME structure, so, when it
changes, you don't lose the customizations.

More details are in the description of the `input_setting',
`input_dipswitch', `input_configswitch' options.

5.18 Cocktail
-------------

For cocktail arcade cabinets you can manually flip vertically the
screen for games without cocktail support.

Press `slash_pad' to flip the screen.

5.19 Dipswitches Control
------------------------

You can customize with specialized options the game difficulty and
the game freeplay. These options are smart enough to solve
common ambiguities and errors in the game dipswitches definitions.

More details are in the description of the `misc_diffucilty' and
`misc_freeplay' options.

5.20 LCD
--------

AdvanceMAME is able to talk to an `lcdproc' server located anywhere
in internet to display arbitrary information on a real or simulated
LCD display.


6 USE CASES
===========

This section describes some useful cases for AdvanceMAME
on different video hardware.

6.1 With a PC Multi-Sync Monitor
--------------------------------

On a PC Multi-Sync monitor you can get any resolution at any
Vertical Frequency. In this case AdvanceMAME always generates
a `perfect' video mode with the correct size and clock. It
doesn't require any type of stretching.
For example for the game "Bomb Jack" a video mode of 400x256
at 60 Hz (perfect size and perfect frequency) is used.

6.2 With a PC VGA Monitor/Fixed Frequency Monitor/Arcade Monitor
----------------------------------------------------------------

On Fixed Frequency monitors you are physically limited on
the choice of Horizontal Frequency in the video mode. In this
case AdvanceMAME takes care of your monitor's limitations
and in the most cases is able to use a video mode with the
correct size but not with the correct frequency due to the
monitor's limitations.
For example for the game "Pac-Man" and a VGA monitor (31.5 kHz)
a video mode of 400x288 at 100 Hz (perfect size) is used.

6.3 With a NTSC or PAL TV
-------------------------

On a TV you are physically limited to use both fixed Horizontal
and Vertical Frequencies. This results on a prefixed number of
rows for the video mode.
For example for a NTSC TV you can get 240 rows (480 if
interlaced) and for a PAL TV 288 rows (576 if interlaced).
In this case AdvanceMAME uses a video mode with the prefixed
number of rows but with the correct number of columns. So,
ONLY a vertical image stretching is required.
For example for the game "Pac-Man" on a NTSC TV a video mode
of 400x240 (perfect horizontal size) is used.
For stretching some special algorithms are used to minimize
the lose of details.

6.4 With a Multi-format NTSC and PAL TV
---------------------------------------

If your TV supports both formats, AdvanceMAME automatically
chooses the format that better fits the game requirements.
For example for the game "Mr. Do!" a video mode of 336x240
NTSC (perfect size) is used. For the game "Pac-Man" a video mode
of 400x288 PAL (perfect size) is used.


7 OTHER PORTS
=============

This section compares the AdvanceMAME video support with the
other MAME ports.

7.1 Windows MAME
----------------

The official Windows MAME is forced by Windows drivers to select
a video mode from a prefixed list of mode sizes and clocks.
If the emulated game requires a not standard mode size the
emulator must stretch the game image to fit the screen (losing in
quality). If the emulated games requires a not standard clock the
emulator must play the game without synchronizing with the video
vertical retrace (generating the tearing disturb on scrolling game)
or display frames for different time (generating a not constant
scrolling).

Depending on the type of your video drivers you can sometimes
edit the prefixed list of video modes.

The TV support depends on the video drivers of your board and
it's generally limited at the interlaced mode 640x480.
Arcade monitors are used as NTSC TVs.

Generally this port is limited by Windows to get the best from
your monitor.

7.2 DOS MAME
------------

The official DOS MAME is limited to use only the standard
VESA resolutions. Generally they are only 320x200,
320x240, 400x300, 512x384, 640x480, ...

The Arcade/TV support is limited at the mode 640x480 for the
ATI boards.

7.3 xmame
---------

The xmame port has nearly the same video capabilities of
AdvanceMAME. The major drawback is that it requires a manual
modeline creation. Instead AdvanceMAME is able to create
modelines dynamically.

AdvanceMAME has also some unique features like `scale',
`lq', `hq', `filter' and `rgb' effects, turbo mode,
scripts, SMP, 8 bit depth and much more.


8 CONFIGURATION
===============

In DOS and Windows the configuration options are read from the
files `advmame.rc' and `advmess.rc' in the current
directory.

In Linux and Mac OS X the configuration options are read from the
files `advmame.rc' and `advmess.rc' in the $host, $data and
the $home directory.
The $host directory is `$SYSCONFDIR', where $SYSCONFDIR is the
`sysconfdir' directory configured with the `configure' script.
The default is `/usr/local/etc'.
The $data directory is `$DATADIR/advance', where $DATADIR is the
`datadir' directory configured with the `configure' script.
The default is `/usr/local/share'.
The $home directory is `$ADVANCE', where $ADVANCE is the value of the
ADVANCE environment variable when the program is run.
If the ADVANCE environment variable is missing the $home directory
is `$HOME/.advance' where $HOME is the value of the HOME environment
variable.
If both the ADVANCE and HOME environment variables are missing the
$data directory became also the $home directory.

The priority of the options is in the order: $host, $home and $data.

The $home directory is also used to write all the information
by the program. The files in the $host and $data directory are only read.

You can include an additional configuration files with the `include'
option. In DOS and Windows the files are searched in the current directory.
In Linux and Mac OS X the files are searched in the $home directory if
they are expressed as a relative path. You can force the search in the
current directory prefixing the file with `./'.
To include more than one file you must divide the names with `;' in
DOS and Windows, and with `:' in Linux and Mac OS X.

You can force the creation of a default configuration file with the
command line option `-default'.

In the configuration file the options are specified in this format:

    [SECTION/]OPTION VALUE

If the SECTION is omitted the `' (empty) section is assumed.

You can split long options in a multi-line format ending the line
with the char `\':

    [SECTION/]OPTION FIRST_LINE \
    	SECOND_LINE \
    	... \
    	LAST_LINE

When you run a game every option is read in different
sections in the following order:

    `SYSTEM[SOFTWARE]' - The short system name and the loaded
        software on the command line, like `ti99_4a[ti-inva]',
        `a7800[digdug]' and `nes[commando]'.
    `GAME' - The short game (or system) name, like `pacman',
        `ti99_4a' and `nes'.
    `PARENT' - If present, the parent name of the game,
        like `puckman'.
    `BIOS' - If present, the bios name of the game,
        like `neogeo'.
    `RESOLUTIONxCLOCK' - The resolution and the clock of the
        game, like `244x288x60' for raster games or
        `vector' for vector games. If the vertical clock
        is a real value, it's rounded downwards to the
        nearest integer.
    `RESOLUTION' - The resolution of the game, like
        `244x288' for raster games or `vector' for
        vector games.
    `ORIENTATION' - The game orientation. One of `vertical',
        `horizontal'.
    `CONTROLLER' - The game input device. One of `joy4way',
        `joy8way', `doublejoy4way', `doublejoy8way',
        `paddle', `dial', `trackball', `stick', `lightgun',
        `mouse'.
    `Nplayer' - Number of players in the game. One of `1player',
        `2player', `3player', ...
    `' - The default empty section.

For example for the game `pacman' the following sections are
read: `pacman', `puckman', `224x288x60', `224x288', `vertical',
`joy4way', `2player' and `'.

You can override any global options inserting new options in
any of the sections of the game.

For example:
    display_scanlines no
    pacman/display_scanlines yes
    244x288x60/display_scanlines yes
    vertical/display_ror yes
    horizontal/display_ror no

8.1 Software Configuration Options
----------------------------------

This section describes the options used to customize the
software loaded by system emulated.

---- 8.1.1 dev_* ----
Loads a specific device for the AdvanceMESS emulator. These
options are mainly used on the command line to specify the
machine software to load.
The file specified is searched in the directory list specified
in the `dir_image' option.

dev_COMMAND FILE

8.2 Directory Configuration Options
-----------------------------------

This section describes the options used to customize the
directories used by the program.

---- 8.2.1 dir_* ----
Specify all the support directories. In DOS and Windows use the `;'
char as directory separator. In Linux and Mac OS X use the `:' char.

dir_* DIR[;DIR]... (DOS, Windows)
dir_* DIR[:DIR]... (Linux, Mac OS X)

Options:
    dir_rom - Multi directory specification for the
        AdvanceMAME `rom' files and AdvanceMESS `bios'
        files.
    dir_image - Multi directory specification for the
        chd/disk/cartdrige/... image files.
    dir_diff - Multi directory specification for the
        disk image differential files.
    dir_sample - Multi directory specification for the
        zipped `sample' files. Only the zipped format
        is supported.
    dir_artwork - Multi directory specification for the
        zipped `artwork' files. Only the zipped format
        is supported.
    dir_nvram - Single directory for `nvram' files.
    dir_memcard - Single directory for `memcard' files.
    dir_hi - Single directory for `hi' files.
    dir_inp - Single directory for `inp' files.
    dir_sta - Single directory for `sta' files.
    dir_snap - Single directory for the `snapshot'
        files.
    dir_crc - Single directory for the `crc' files.

Defaults for DOS and Windows:
    dir_rom - rom
    dir_image - image
    dir_diff - diff
    dir_sample - sample
    dir_artwork - artwork
    dir_nvram - nvram
    dir_memcard - memcard
    dir_hi - hi
    dir_inp - inp
    dir_sta - sta
    dir_snap - snap
    dir_crc - crc

Defaults for Linux and Mac OS X:
    dir_rom - $home/rom:$data/rom
    dir_image - $home/image:$data/image
    dir_diff - $home/image:$data/diff
    dir_sample - $home/sample:$data/sample
    dir_artwork - $home/artwork:$data/artwork
    dir_nvram - $home/nvram
    dir_memcard - $home/memcard
    dir_hi - $home/hi
    dir_inp - $home/inp
    dir_sta - $home/sta
    dir_snap - $home/snap
    dir_crc - $home/crc

If a not absolute dir is specified, in Linux and Mac OS X
it's expanded as "$home/DIR:$data/DIR". In DOS and Windows
it's maintained relative.

For the `dir_rom' and `dir_image' the following file
combinations are tried:

* DIR/GAME/ROM.EXT
* DIR/GAME.zip/ROM.EXT
* DIR/GAME/ROM.zip/ROM

Where DIR is substituted with the directories specified, GAME
is the name of the game or machine emulated, ROM is the rom
name and EXT is the rom extension.

For the files searched in the `dir_image' option you can also
specify a different zip name prefixing the rom name
with the zip name without extension and the `=' char.
For example to run the `ti99_4a' emulator and load the
cartdriges `alpinerc.bin' and `alpinerg.bin' both contained in
the zip file `alpiner.zip' you can use this syntax:

    advmess ti99_4a -cart alpiner=alpinerc.bin -cart alpiner=alpinerg.bin

This feature is used automatically by AdvanceMENU to correctly
run AdvanceMESS software in zip files.

8.3 Display Configuration Options
---------------------------------

This section describes the options used to customize the
display.

---- 8.3.1 device_video_* ----
These options are used to customize the video drivers.

All the `device_video_*' options described in the `advdev.txt' file
can be used.

If you use a `System' video driver, you don't need to set these
options. They are mostly ignored.

With a `Generate' video drivers these options are used to select
and create the correct video mode. They are mandatory. You can use
the `advcfg' utility to set them interactively.

---- 8.3.2 display_mode ----
Selects a specific modeline by its name.

display_mode auto | MODELINE_NAME

Options:
    MODELINE_NAME - Specific modeline, as named with
        the `advv' utility.
    auto - Automatically chooses the best modeline
        available (default).

---- 8.3.3 display_adjust ----
Controls how are generate the video modes. Correct use of this
option removes the need of any software stretching improving a
lot the game image.

For an introduction on how the program operates on video mode,
you can see the `install.txt' file.

display_adjust none | x | clock | xclock | generate_exact
	| generate_y | generate_clock | generate_clocky
	| generate_yclock

Options:
    none - No automatic video mode creation. Use only the
        available modelines (default).
    x - Adjusts the available modeline horizontal resolution
        to match the game image's size. The stretched modeline
        keeps all the clock attributes of the original
        modeline. Also all other modeline attributes,
        like doublescan and interlace, are maintained.
    clock - Adjusts the available modeline's vertical clock
        to match the game's frame rate.
    xclock - Adjusts the available modeline's horizontal resolution
        and the vertical clock.
    generate_exact - Creates automatically some new modelines using
        the format specified on the `device_video_format'
        option. The generated modelines will be named `generate-*'.
        Check the `advdef.txt' file for the description of
        the `device_video_format' option or simply use the
        `advcfg' utility to set it up correctly.
        If the `device_video_format' option isn't
        specified a default value for your monitor clock
        limits is guessed.
    generate_y - Like generate_exact, and it allows generating
        modes with a wrong vertical size if a perfect mode is not
        possible.
    generate_clock - Like generate_exact, and it allows generating
        modes with a vertical clock different than the game
        original clock if a perfect mode is not	possible.
    generate_yclock - Like generate_exact, and it allows
        generating modes with a wrong vertical clock and/or size
        if a perfect mode is not possible. Modes with a correct size
        are favorite over mode than a correct clock.
    generate_clocky - Like generate_exact, and it allows
        generating modes with a wrong vertical clock and/or size
        if a perfect mode is not possible. Modes with a correct clock
        are favorite over mode with a correct size.

The `generate' options are able to create at runtime all the
required modelines. You don't need to create a list of modelines
manually.

The not `generate' options use only the modelines defined with
the `device_video_modeline' option in the configuration file.
You can add them manually or using the `advv' utility.
Check the `advdev.txt' file for more details on the
`device_video_modeline' option.

Of all the `generate' options, the `generate_yclock' is the
suggested and the most powerful. The `advcfg' utility always
sets the `generate_yclock' option in your configuration file.

Of all the not `generate' options, the `xclock' is the
suggested and the most powerful.

If you can't get good result with the `generate' options you
should create a list of modelines and try with the `xclock' value.
You don't need to duplicate the same modeline with different
horizontal resolutions and/or the clocks, because the `xclock'
value allows the program to adjust them.
Instead, you should create a wide set of different vertical
resolutions on which the video mode can be chosen.
A good choice is to create all the resolutions with a step of
16 rows.

---- 8.3.4 display_color ----
Controls the color format of the video mode.

display_color auto | palette8 | bgr8 | bgr15 | bgr16 | bgr32 | yuy2

The modes are called bgr because in the video memory the order of
the color channel is: Blue, Green, Red.

---- 8.3.5 display_resize ----
Suggests the favorite image stretching when a video mode
with the correct size isn't available.
This option doesn't have any effect for vector games, they are
always stretched to fit the whole screen.

display_resize none | integer | mixed | fractional

Options:
    none - Original size.
    integer - Integer stretch, i.e. x2, x3, x4,...
    mixed - Integer horizontal stretch and fractional
        vertical stretch (default).
    fractional - Fractional stretch.

The `fractional' option involves a slowdown, so the `mixed'
option is the default.

Examples:
    display_resize mixed

---- 8.3.6 display_magnify ----
Suggests the use of a double or bigger resolution video mode.
It is mainly used to enable the `scale', `lq' and `hq'
effects. This option doesn't have any effect for vector games.

display_magnify auto | 1 | 2 | 3 | 4

Options:
    auto - Double or triplicate the size if the resulting
        video mode width is smaller than 512 pixels.

    no - Doesn't use any buffering (default).
    yes - Use the best buffering available.

---- 8.3.9 display_vsync ----
Synchronizes the video display with the video beam instead of
using the CPU timer. This option can be used only if the
selected video mode has an appropriate refresh rate.
To ensure this you can use the option `display_adjust' to allow
a clock correction of the video mode.

display_vsync yes | no

Options:
    no - Use the timer.
    yes - Use the video refresh rate (default).

You can enable or disable it also on the runtime Video menu.

---- 8.3.10 display_restore ----
Selects whether or not to reset to default text mode at the
emulator exit.

display_restore yes | no

Options:
    yes - Resets to text mode (default).
    no - Doesn't change the video mode.

---- 8.3.11 display_frameskip ----
Skips frames to speed up the emulation.

display_frameskip auto | FACTOR

Options:
    auto - Auto frame skip (default).
    FACTOR - Float factor for the fraction of frames
        to display. From 0 to 1. To completely
        disable the frame skipping use the
        value 1.

Use `f11' to display the speed your computer is actually
reaching. If it is below 100%, increase the frame skip value.
You can press `f8/f9' to change frame skip while running the game.
When set to auto (default), the frame skip setting is
dynamically adjusted during runtime to display the maximum
possible frames without dropping below the 100% speed.
Pressing `f10' you can enable and disable the throttle
synchronization.

Examples:
    display_frameskip 0.5

screen, the `resizeeffect' option controls the type of the
transformation applied.

display_resizeeffect auto | none | max | mean | filter
	| scale | lq | hq

Options:
    auto - Selects automatically the best effect (default).
        This selection is list based, and may be
        incomplete.
        If the scale factor is 2, 3 o 4 the `scale' effect
        is selected.
        On the other cases the `mean' or `max' effect
        is selected.
    none - Simply removes or duplicates lines as required.
    max - In reduction merges consecutive columns and rows using the
        lightest pixels versus the darkest.
        In expansion duplicate columns and rows using the
        darkest pixels versus the lightest.
        Supported in both rgb and palette video modes.
        It works best for the games with black
        background or without scrolling. Like "Pac-Man".
        This effect ensures to have always rows and columns
        of the same thickness.
    mean - In reduction it merges columns and rows using the
        mean color of the pixels. In expansion it adds
        columns and rows that are the mean of previous
        and next lines.
        Supported only in rgb video modes.
        It works best for the games with animated
        or scrolling background. Like "1941".
    filter - It removes or duplicates columns and rows with
        a low pass filter in the x and the y directions.
        It's a simple FIR filter with two points of
        equal value.
        Supported only in rgb video modes.
    scale - It adds the missing pixels matching the
        original bitmap pattern.
        It doesn't interpolate pixels and it compares colors
        for equality.
        If works only for expansion factor of 2, 3 and 4.
    lq - It adds the missing pixels matching the
        original bitmap pattern. It uses a deeper analysis
        than `scale'. It interpolates pixels and it
        compares colors for equality.
        It works only for expansion factor of 2, 3 and 4,
        and only in rgb modes at 15, 16 and 32 bits per pixel.
    hq - It adds the missing pixels matching the
        original bitmap pattern. It uses a deeper analysis
        than `scale'. It interpolates pixels and it
        compares colors for distance.
        It works only for expansion factor of 2, 3 and 4,
        and only in rgb modes at 15, 16 and 32 bits per pixel.

---- 8.5.2 display_rgbeffect ----

Options:
    none - No effect (default).
    even - Swap the even rows.
    odd - Swap the odd rows.
    filter - Apply a vertical filter.

If your monitor uses a swapped order for interlaced rows, using the
`even' or `odd' effect you can probably fix the image.

The effects operate on the rows in the following way:

    Row Even Odd Filter
     A   A   A    A
     B   B   A   B+A

file can be used.

---- 8.8.2 sound_mode ----
Sets the sound output mode.

sound_mode auto | mono | stereo | surround

Options:
    auto - Use mono if the emulated game is mono
        or stereo if it's stereo (default).
    mono - Use always mono. The game stereo channels
        are mixed.
    stereo - Use always stereo. The game mono channel
        is duplicated.
    surround - Use a fake surround effect. With

        With mono games the left channel is the negation of
        the right channel. This means that with surround
        enabled the output is always stereo.
        If you use mono headphones, the effect will not
        work and you will hear silence or an attenuated
        sound.

---- 8.8.3 sound_samplerate ----
Sets the audio sample rate.

sound_samplerate RATE

Options:
    RATE - Sample rate. Common values are 11025, 22050,

The `joystick' option is used to reference all the analog
controls which report an absolute position. For example
stick, lightgun, steering wheel, pedal, throttle and rudder controls.

The `joystick_ball' and `mouse' options are used to reference
all the analog controls which reports a relative position. For
example trackball, dial and mouse controls.
The option `joystick_ball' is for joystick devices which
have other relative analog controls. The option `mouse' is
for mouse devices which have only relative analog controls.

The exact CONTROL and AXE names can be checked interactively
using the `advj' and `advm' utility. `advj' is used for
`joystick[]' and `joystick_ball[]' specifications. `advm' is
used for `mouse[]' specifications.

If required you can compose the options to get a rotation
of 45° of the control. For example:

    input_map[p1_stickx] mouse[0,x] mouse[0,y]
    input_map[p1_sticky] mouse[0,x] -mouse[0,y]

---- 8.9.6 input_map[DIGITAL] ----
Changes the digital control mapping. Maps a sequence of
keyboard/mouse/joystick keys on a player button or analog
simulation digital control.

input_map[DIGITAL] auto | keyboard[KEYBOARD,KEY]
	| mouse_button[MOUSE,MOUSE_BUTTON] | joystick_button[JOY,JOY_BUTTON]
	| joystick_digital[JOY,CONTROL,AXE,DIR]
	| or | not | ...

The default is always `auto' which uses the standard mapping.
The previous mapping is always overwritten.

Options:
    DIGITAL - Player button, analog simulation, digital or
        keyboard control.
    KEYBOARD - Number of physical keyboard: 0, 1, 2, 3, ...
    KEY - Name of physical key.

        0, 1, 2, 3, ...
    JOY - Number of physical joystick: 0, 1, 2, 3, ...
    CONTROL - Number or name of physical control of the joystick: 0, 1, 2, 3, ...
    DIR - Direction of the movement: left, up, right, down.
    AXE - Number or name of physical axe of the control: 0, 1, 2, 3, ...
    JOY_BUTTON - Number or name of a physical joystick button:
        0, 1, 2, 3, ...
    or - Or operand.
    not - Not operand.

recording and to save the clip press `enter'. If you press the
start key more than one time the recording starts from the
last press.

---- 8.11.1 record_sound ----
Enables or disables the sound recording.

record_sound yes | no

The sound clip is saved in the `dir_snap' directory (like the
snapshot images) in `.wav' format. Specifically the `WAV PCM
16 bit' format is used. The sample rate used is the same sample
rate specified with the `sound_samplerate' option.

The clip is saved without compression and without any volume
adjustment. You should use an external utility to adjust the
volume and compress the resulting file.

---- 8.11.2 record_video ----
Enables or disables the video recording.

record_video yes | no

The video clip is saved in the `dir_snap' directory (like the
snapshot images) in `.mng' format. The `MNG-LC' (Low Complexity)
subformat is used.

The clip is saved with a lite compression, you should use an
external utility to compress better the resulting file.

A powerful compression utility is the `advmng' program
available in the AdvanceCOMP package.

---- 8.11.3 record_video/sound_time ----
Controls the maximum length in seconds of the recording feature.

record_sound_time TIME
record_video_time TIME

Options:

        (default 2). 1 means save all the frames. 2
        means save 1 every 2. 3 means save 1 every 3,
        and so on.

Examples:
    record_video_interleave 1

8.12 Synchronization Options
----------------------------

This section describes the options used for the time synchronization
of the emulated game or system.

---- 8.12.1 sync_fps ----
Selects an arbitrary frame rate for the game.

sync_fps auto | FPS

Options:
    auto - Use the original framerate of the game (default).
    FPS - Use the specified framerate.

---- 8.12.2 sync_speed ----
Selects a speed factor always active. You can play the game
in slowdown or in nightmare mode!

sync_speed FACTOR

Options:
    FACTOR - Float speed factor (default 1.0).

Examples:
    sync_speed 1.2

---- 8.12.3 sync_turbospeed ----
Selects the speed factor used when the `turbo' button is
pressed. The default `turbo' key is `asterisk_pad'.

sync_turbospeed FACTOR

Options:
    FACTOR - Float speed factor (default 3.0).

---- 8.12.4 sync_startuptime ----
Selects the time in seconds of the duration of the startup
speed up. You can press the `startup' key to save the current
game time as startup time. The default `startup' key
is `minus_pad'.

sync_startuptime auto | none | TIME

Options:
    auto - Get the value for the current game from
        an internal database (default).
    none - Disable the startup.
    TIME - Time in seconds.

---- 8.12.5 sync_resample ----
Selects the audio resampling mode.

sync_resample auto | emulation | internal

Options:
    auto - Select automatically, at present it's always
        the `internal' mode (default).
    emulation - Change the emulation to produce the requested
        number of samples instead of resampling.
    internal - Internally resample the sound to match the
        current speed.

Note that the `emulation' mode may result in wrong input recording
using the `-record' or `-playback' command line option due incorrect
behavior of the emulation. Specifically some implementations may
depend on the number of audio sample requested, information that
is not stored in the recorded input file.

Also, the `emulation' mode may trigger some bugs in the MAME
core.

Anyway, the `emulation' mode generates more stable sound
if the CPU load isn't totally empty.

8.13 LCD Configuration Options
------------------------------

AdvanceMAME is able to display arbitrary information on a LCD display
using the integrated script capabilities.

To use the LCD support you must install on your system the `lcdproc'
program available at:

    http://lcdproc.sourceforge.net/

More details and some examples of how to display information on the LCD
using the scripts are in the `script.txt' documentation file.

---- 8.13.1 lcd_server ----
Selects the server address and port to use for display information on
the LCD.

lcd_server none | [SERVER][:PORT]

Options:
