You can use short options if they are unambiguous. You can remove any prefix tag separated with `_' or truncate it. For example `-dev_cartdrige' can be written as `-dev_cart', `-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', `scalex', `scalek', `lq', `hq' and `xbr'. You can select the favorite effect with the `display_resizeeffect' option, or from the runtime menu.

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 `scalex', `scalek', `lq', `hq' and `xbr' effects add missing pixels trying to match the image patterns.

The `scalex', `scalek', `lq', `hq' and `xbr' 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.

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 Panel

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

6 Use Cases

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

6.1 With a LCD Monitor

On a LCD Monitor, AdvanceMAME is able to use the hardware acceleration of your video board to stretch the game image to fit the exact resolution of your LCD monitor. With an HighDefinition monitor (1920x1080/1200), this stretching is not noticeable and you get an image with quality comparable with a CRT Multi-Sync monitor. You can also use a bunch of video effects to remove the annoying pixelation or to emulate old stylish CRT aspect.

6.2 With a CRT 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.

6.3 With a CRT 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 it's 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.

6.4 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.

6.5 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 SDL MAME

The official SDL MAME, is similar at AdvanceMAME when using the sdl video driver, which is the default when run in a modern Desktop environment.

AdvanceMAME has the benefit to allow to use more video effects, able to improve the image quality.

This also helps when using Arcade Monitors with specific modelines, because AdvanceMAME is able to streatch the image using special effects like 'max' that avoids to lose pixels.

7.3 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.

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

Commands:

cartridge Load a cartridge.
floppydisk Load a floppydisk.
harddisk Load an harddisk.
cylinder Load a cylinder.
cassette Load a cassette.

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

8.2 Autosave Configuration Options

8.2.1 config

Selects if and when the configuration modified by the user at runtime should be saved.

config save_at_exit | restore_at_exit

Options:

save_at_exit Save any changes before exiting (default).
restore_at_exit Don't save the changes. At the next run, restore the previous configuration.

You can manually save the configuration at runtime from the main menu.

8.3 Directory Configuration Options

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

8.3.1 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:

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.

8.4 Display Configuration Options

This section describes the options used to customize the display.

8.4.1 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.

8.4.2 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).

8.4.3 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.

8.4.4 display_color

Controls the color format of the video mode.

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

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.

8.4.11 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.

8.4.12 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

8.5 Display Aspect Configuration Options

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 `xbr' effect is selected. The effect is automatically downgraded to `scalek' or `scalex' if the emulation is too slow. 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.
scalex It adds the missing pixels matching the original bitmap pattern. It uses a 3x3 mapping analysis with 4 comparisons. It doesn't interpolate pixels and it compares colors for equality. If works only for expansion factor of 2, 3 and 4.
scalek It adds the missing pixels matching the original bitmap pattern. It uses a 3x3 mapping analysis with 4 comparisons. It interpolates 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 3x3 mapping analysis with 8 comparisons. It interpolates pixels and it compares colors for equality. It works only for expansion factor of 2, 3 and 4.

Options:

auto Get the value for the current game from an internal database.
VOLUME The volume gain in dB (default 0). The gain is a positive value from 0 to 40. If the `sound_normalize' option is active the volume is automatically updated in the game play.

Examples:

sound_adjust 16

8.9.6 sound_normalize

Automatically increases and decreases the sound volume.

sound_normalize yes | no

Precisely, the program continously measures the normalized sound power adjusting it with the Fletcher-Munson "Equal Loudness Courve" at 80 dB to remove inaudible frequencies. It tries to keep constant the 95% median power of the last 3 minutes.

For more details check:

http://replaygain.hydrogenaudio.org/equal_loudness.html

Options:

yes Enable the volume normalization (default).
no Disable it.

8.9.7 sound_equalizer_*

sound_equalizer_lowvolume VOLUME sound_equalizer_midvolume VOLUME sound_equalizer_highvolume VOLUME

Options:

VOLUME The volume gain in dB (default 0). The gain is a integer value from -20 to 20.

8.9.8 sound_latency

Sets the audio latency. The latency is the delay between a sound is generated and before you hear it. You generally want a small latency, but a bigger latency avoids sound clicks in case the audio reproduction is too slow.

sound_latency TIME

Options:

TIME Latency in seconds from 0.01 to 2.0 (default 0.05).

If in the game play you hear some sound ticks you can try to increase the latency. Try doubling the value until the ticks go away.

This section describes the options used for the recording features.

To start the recording press `left_ctrl+enter'. To end the 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.

8.12.1 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.

8.12.2 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.

8.12.3 record_video/sound_time

Controls the maximum length in seconds of the recording feature.

record_sound_time TIME
record_video_time TIME

Options:

TIME Time in seconds (default 15).

8.12.4 record_video_interleave

Selects how many frames to save with the video recording.

record_video_interleave COUNT

Options:

8.13 Synchronization Options

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

8.13.1 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.

8.13.2 sync_speed

sync_speed FACTOR

Options:

FACTOR Float speed factor (default 1.0).

Examples:

sync_speed 1.2

8.13.3 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).

8.13.4 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.

8.13.5 sync_resample

Selects the audio resampling mode.

sync_resample auto | emulation | internal

Options:

auto Select automatically. It's almost always the `emulation' mode with the exception of some games like 'starwars' and others using the pokey sound chip. (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.

The `emulation' mode may trigger some bugs in the MAME core. For this reason the games using the pokey sound chip by default use the `internal' mode.

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

8.14 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/

For example if you run `cadash' with `-lang italy' it's run the clone `cadashi'. If you run `cheesech' with `-lang germany' it's run `cheesech' setting the `Language' dipswitch to `German'.

If the specified language is not available, european and american languages fallback to english language. Asian languages fallback to japanese language.

A game clone is selected only if it's a perfectly working clone.

8.15.8 misc_smp

Enables the "Symmetric Multi-Processing" (SMP). This option uses two concurrent threads. One for MAME and one for updating the screen. The final blit stage in video memory is completely done by the second thread. This behavior requires a complete bitmap redraw by MAME for the games that don't already do it. Generally you get a speed improvement, especially if you are using a heavy video effect like `hq' and `xbr'.

misc_smp yes | no

Options:

no Disabled.
yes Enabled (default).

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