## 1 Video Drivers

### 1.1 Types of Drivers

The video drivers can be divided in two different categories:

- Generate drivers able to program directly the video board.
- System drivers able to use only the available video modes.

#### 1.1.1 Generate drivers

This set of drivers is able to program directly the video board to always generate a perfect video mode with the correct size and frequency.

They always work in `fullscreen' output mode and generally support only a subset of video boards.

To function correctly these drivers require a correct configuration of the `device_video_*' options.

The `Generate' drivers are always the preferred choice.

#### 1.1.2 System drivers

This set of drivers is able to use only the video modes available on the operating system.

They can work in `fullscreen' mode, `window' mode and `zoom' output mode using the video board hardware acceleration to stretch the image. The default output mode is `window' if you run the program in a window manager, otherwise the output mode `fullscreen' is chosen.

Please note that these drivers generally need to stretch the image losing a lot in image quality and speed.

These drivers don't require any `device_video_*' options because they cannot control how the video modes are generated.

### 1.2 Available Generate Drivers

The following is the list of all the video drivers supported.

#### 1.2.1 svgalib - Generate SVGA video (Linux)

This driver works in Linux and is able to use video modes obtained tweaking the hardware registers of the recognized SVGA boards using the SVGALIB library.

All clocks, all RGB bit depths are available. This driver is generally able to synchronize with the vertical sync of the video mode.

To use these modes your video board must be supported by a `svgalib' driver listed in the `cardlinx.txt' file. To use this driver you need to install the SVGALIB library version 1.9.x.

To use this driver you need to correctly configure the SVGALIB HorizSync and VertRefresh options in the file /etc/vga/libvga.config file. You must use a range equal or a bit larger than the range specified with the AdvanceMAME `device_video_clock' option.

This driver is not available in X (when the environment DISPLAY variable is defined).

In the `contrib/svgalib' directory there are various SVGALIB patches to fix some problems with recent video boards, and to work with systems with kernel 2.6 and udev.

#### 1.2.2 fb - Generate Frame Buffer video (Linux)

This driver works in Linux and is able to create video modes using the Linux Kernel Frame Buffer interface.

All clocks, all RGB bit depths are available.

This driver is able to use the Linux fb API to synchronize with the vertical sync of the video mode, but generally it isn't possible because the low-end drivers don't support this feature. Anyway, if you run the program as root it can use the standard VGA registers to detect the vsync. This is the major limitation compared with the svgalib driver.

To allow any user to run the program as root, you can use the following commands to change the executable permissions:

    chown root:root /usr/local/bin/advmame
    chmod u+s /usr/local/bin/advmame

To use this driver you must activate the Console Frame Buffer support in your Linux kernel.

This driver is not available in X (when the environment DISPLAY variable is defined).

The Frame Buffer device opened is `/dev/fb0' and `/dev/fb/0', you can change it setting the FRAMEBUFFER environment variable.

The generic Frame Buffer `vesafb' driver cannot be used because it doesn't allow the creation of new video modes. If it's your only option you can use it through the SDL library.

#### 1.2.3 svgaline - Generate SVGA video (DOS)

This driver works in DOS and is able to use video modes obtained tweaking the hardware registers of the recognized SVGA boards.

All clocks, all RGB bit depths are available.

To use these modes your video board must be supported by a `svgaline' driver listed in the `carddos.txt' file.

This driver is completely independent of the VGA/VBE BIOS of your board.

#### 1.2.4 vbeline - Generate VBE video (DOS)

This driver works in DOS and is able to use video modes obtained tweaking the standard VBE (VESA) BIOS mode changing the hardware registers of the SVGA.

All clocks, all RGB bit depths are available.

To use these modes your video board must be supported by a `vbeline' driver listed in the `carddos.txt' file.

These drivers work setting a video mode using the default VBE2 services and tweak some hardware SVGA registers to modify the obtained video mode. The driver `vbe3' is an exception. It requires the presence of a VBE3 BIOS to change the frequency of the desired video mode. Unfortunately the standard VBE3 services don't support a resolution size change.

The resolution is changed modifying only the standard VGA registers. This hack may or not may works. Also the interlaced modes are only rarely supported by the various VBE3 BIOS because they are very rarely used in the standard PC monitors.

If your video board isn't supported by any drivers and you don't have a VBE3 BIOS you can try installing a software VESA BIOS like the SciTech Display Doctor.

#### 1.2.5 vgaline - Generate VGA video (DOS)

This driver works in DOS and is able to use video modes obtained tweaking the hardware registers of the standard VGA.

Only the standard VGA pixel clocks 6.29, 7.08, 12.59, 14.16 MHz are available. Only 8 bit color modes. Only 64 kBytes of video memory.

This driver supports also text modes with pixel clocks 12.59, 14.16, 25.17, 28.32 MHz.

This driver is completely independent of the VGA BIOS of your board.

#### 1.2.6 svgawin - Generate SVGA video (Windows)

This driver works in Windows NT/2000/XP and is able to use video modes obtained tweaking the hardware registers of the recognized SVGA boards.

All clocks, all RGB bit depths are available.

To use these modes your video board must be supported by a `svgawin' driver listed in the `cardwin.txt' file.

To use this driver you need to install the included SVGAWIN driver. Please read the `svgawin.txt' file carefully.

This driver is experimental. At present it's only tested on Windows 2000 with a GeForce 2 board. It may not work will all the other boards.

### 1.3 Available System Drivers

The following is the list of all the System video drivers supported.

#### 1.3.1 sdl - System SDL video (Linux, Windows and Mac OS X)

This driver works in Linux, Windows and Mac OS X and is able to use video modes reported by the SDL graphics library.

It supports all RGB/YUY2 bit depths available. The output in the YUY2 modes is generally accelerated, and can be used to scale the video output to an arbitrary size. You can enable this feature with the `-device_video_output overlay' option.

You can change some options of this driver using the SDL specific environment variables described in the contrib/sdl/env.txt file.

#### 1.3.2 slang - System sLang text video (Linux)

This driver works in Linux and is able to use current terminal text mode from the Linux sLang library.

#### 1.3.3 curses - System curses text video (Linux)

This driver works in Linux and is able to use current terminal text mode from the Linux ncurses library.

#### 1.3.4 vbe - System VBE video (DOS)

This driver works in DOS and is able to use video modes reported by the VBE BIOS.

## 2 Sound Drivers

#### 2.1.3 sdl - SDL sound (Linux, Windows and Mac OS X)

This driver works in Linux, Windows and Mac OS X and it uses the SDL library.

It isn't able to use the hardware volume control of the sound card. The volume changes are simulated reducing the sample values.

It isn't able to precisely control the amount of bufferized samples. This means that it may add a small latency on the sound output.

You can change some options of this driver using the SDL specific environment variables described in the contrib/sdl/env.txt file.

#### 2.1.4 seal - SEAL sound (DOS)

This driver works in DOS and it uses the SEAL sound library with some specific changes for MAME.

The source patch and the library source can be downloaded from the MAME site:

#### 3.2.1 event - Kernel Input-Event interface (Linux)

This driver works in Linux and it uses the new style input-event interface of the Linux kernel.

It supports more than one joystick or light-gun at the same time.

For USB devices this driver doesn't require any configuration. It's able to autodetect all the present hardware.

This driver is also able to correctly report the type of devices found. You should for example expects to have the gas pedal mapped on the gas control of the game.

It can also be used with some custom devices connected at the Parallel Port. Details on how to build these custom interfaces are in the file:///usr/src/linux/Documentation/input/joystick-parport.txt file.

It has a special support for the ACT Labs Lightgun to fix the wrong behavior of the light-gun when shooting out of screen.

The joysticks are searched on the /dev/input/eventX devices.

## 4 Video Drivers Configuration

The following are the video configuration options available for all the programs.

### 4.1 Common Configuration Options

#### 4.1.1 device_video

Selects the video driver to use.

    device_video auto | (DEVICE[/MODEL])+

Options:

| auto | Automatic detection of all the available drivers (default).

The order of detection:

| DOS | svgaline, vbeline, vgaline, vbe.
| Linux | svgalib, fb, sdl, slang, curses.
| Mac OS X | sdl.
| Windows | svgawin, sdl.

Options for Linux:

| curses | Text video modes with the ncurses library.
| sdl | SDL graphics and fake text modes.

Options for Mac OS X:

| sdl | SDL graphics and fake text modes.

Options for DOS:

| svgaline | SVGA generated graphics modes.
| svgaline/nv3_leg | SVGA legacy driver for nVidia boards. If the new driver doesn't work try this one.
| svgaline/savage_leg | SVGA legacy driver for S3 boards. If the new driver doesn't work try this one.
| vbeline | VBE generated graphics modes.
| vgaline | VGA generated text and graphics modes.
| vbe | VBE graphics modes.

Options for Windows:

| svgawin | SVGA generated graphics modes with the SVGAWIN included library. To use this driver you need to install the `svgawin.sys' driver with the `svgawin.exe' command line utility.
| svgawin/nv3_leg | SVGA legacy driver for nVidia boards. If the new driver doesn't work try this one.
| svgawin/savage_leg | SVGA legacy driver for S3 boards. If the new driver doesn't work try this one.
| sdl | SDL graphics and fake text modes.

Please note that to use the utilities `advv' and `advcfg' you must at least select a graphics and a text video driver. The available text video drivers are `vgaline' for DOS, `slang', `curses' for Linux and `sdl' for Windows.

You can force the detection of a specific model of video board adding the name of the model driver after the driver name using the `/' separator. For example to force the `vbe3' model detection of the `vbeline' driver you must specify `vbeline/vbe3'.

To get the list of all the available models try using the `help' model name. A short help will be printed.

Please note that forcing a specific video driver is discouraged. Generally you don't need it.

For a more complete description of the drivers check the previous `VIDEO DRIVER' section.

Example to enable the `vbeline' and the `vgaline' drivers with auto-detection for DOS:

    device_video vbeline vgaline

Example to force the `vbeline/vbe3' driver and the `vgaline' driver for DOS:

    device_video vbeline/vbe3 vgaline

Example to enable the `fb' and `slang' driver for Linux:

    device_video fb slang

#### 4.1.2 device_video_output

Select the output mode.

    device_video_output auto | window | fullscreen | overlay

Options:

| auto | Automatically chosen (default).
| window | Use a window display.
| fullscreen | Use a fullscreen display.
| overlay | Use a YUV fullscreen overlay using the video board hardware acceleration to display and stretch it. This mode is available only in some environments, like xv in X Window and DirectX in Windows. The specific color format used is YUY2.

Please note that with overlay mode, if the original image is in the RGB format instead of a palette format, the program needs to convert it to the YUY2 format before displaying it. It requires some time.

#### 4.1.3 device_video_overlaysize

Select the favorite horizontal size to use with the `overlay' output mode. The program selects the nearest available video mode.

device_video_overlaysize SIZE

Options:

| SIZE | The favorite horizontal size (default 1024).

This option has effect only with the `overlay' output mode.

#### 4.1.4 device_video_cursor

Select the mouse cursor mode.

    device_video_cursor auto | off | on

Options:

| auto | Automatically choose (default). The cursor is enabled in window modes, and disabled in fullscreen modes.
| off | Always off.
| on | Always on, only if the video mode support it.

### 4.2 Generate Configuration Options

The following are the common video configuration options available for all `generate' video drivers, i.e. all the video drivers with the exception of `sdl' and `vbe'. The `sdl' and `vbe' video drivers simply ignore these options.

#### 4.2.1 device_video_clock

Specify the monitor frequency range in term of horizontal and vertical clocks. This option is MANDATORY. Generally these values are specified in the technical page of your monitor manual.

    device_video_clock PIXEL_CLOCK / HORZ_CLOCK / VERT_CLOCK [; ...]

Options:

| PIXEL_CLOCK | Pixel clock range in MHz. The lower value is the lower clock generable by your video board. The higher value is the video bandwidth of your monitor. If you don't know these values you can start with `5 - 100' which essentially enable any video mode.
| HORZ_CLOCK | Horizontal clock range in kHz.

| VERT_CLOCK- Vertical clock range in Hz.

For any range you can specify a single value like `60' or a range of values like `50 - 60'. For multistandard TVs and monitors you can use more clock specifications separating them with `;'.

For example:

    device_video_clock 5 - 50 / 15.62 / 50 ; 5 - 50 / 15.73 / 60

Check the `install.txt' file for examples and other information.

#### 4.2.2 device_video_modeline

Define a video modeline. The modeline format is compatible with the format used by the Linux SVGALIB library and by the XFree Window system.

    device_video_modeline Name CLOCK HDE HRS HRE HT VDE VRS VRE VT
        [-hsync] [-vsync] [+hsync] [+vsync] [doublescan] [interlace]

Options:

| Name | Name of the video mode. You can use the quotes '"` for the names with spaces.
| CLOCK | Pixel clock in MHz
| HDE HRS HRE HT | Horizontal `Display End', `Retrace Start', `Retrace End', `Total'
| VDE VRS VRE VT | Vertical `Display End', `Retrace Start', `Retrace End', `Total'
| -hsync -vsync +hsync +vsync | Polarization mode.
| doublescan | Doublescan mode.
| interlace | Interlaced mode.

Examples:

    device_video_modeline tweak320x240 12.59 320 336 356 400 240 \
        249 254 262 doublescan -hsync -vsync

#### 4.2.3 device_video_format

Select the format of the video modes to create. You can insert more than one of these option.

    device_video_format HCLOCK HDE HRS HRE HT VDE VRS VRE VT

Options:

| HCLOCK | Horizontal clock in Hz
| HDE HRS HRE HT VDE VRS VRE VT | Like the modeline option

When a new modeline is created, AdvanceMAME uses a linear interpolation of the two formats with the nearest horizontal clock.

The default value of this option is for an Arcade 15 kHz monitor:

    15720 0.737 0.075 0.074 0.113 0.916 0.012 0.012 0.060

and for an Arcade 25 kHz monitor:

    25000 0.800 0.020 0.100 0.080 0.922 0.006 0.012 0.060

and for a VGA 31.5 kHz monitor:

    31500 0.800 0.020 0.120 0.060 0.914 0.019 0.004 0.063

Which one of these defaults is used depends on the setting of the `device_video_clock' option.

Other possible choices generally are 'hw:0,0' for using the frequency and format chosen directly by the hardware, or 'dmix' for allow concurrent access to other applications at the audio card.

Example:

    device_alsa_device dmix

If you want to configure the ALSA library to remap the `default' device to the `dmix' device for all the applications, you can create the `.asoundrc' file in your home directory with the following content:

    pcm.!default {
        type plug
        slave.pcm "dmixer"
    }

    pcm.dmixer  {
        type dmix
        ipc_key 1024
        slave {
            pcm "hw:0,0"
            period_time 0
            period_size 1024

        }
    }

    ctl.dmixer {
        type hw
