enables some memory increasing inlines. This greatly increases
compiletime for maybe a increase in speed.
--disable-dynamic-x86
disables the dynamic cpu core. Although it's unstable it can greatly
improve the speed of dosbox on x86 hosts.
--disable-fpu-x86

Q: The mouse doesn't work.
A: Normally DOSBox detects the mouse being used by a game. If you click on
the screen then it should get locked (confined to the DOSBox window)
and work. Sometimes the DOSBox mouse detection doesn't work with certain
games. You might have to force to lock the mouse then with ctrl-F10.

The configuration file controls various settings of DOSBox:
the amount of emulated memory, the emulated soundcards and many more
things. It allows access to AUTOEXEC.BAT as well.
See section 9 (The Config File) for more information.
-writelang localfile
Write the current language settings to file. "localfile" is
located on the local drive, not a mounted drive in DOSBox.
The language file controls all visible ouput of the internal commands
and the internal dos.
-set "section property=value"
CONFIG will attempt to set the property to new value. At this moment
CONFIG can not report whether the command succeeded or not.
-get "section property"
The current value of the property is reported and stored in the
environment variable %CONFIG%. This can be used to store the value
when using batch files.
Both "-set" and "-get" work from batch files and can be used to set up your
own preferences for each game.
Examples:
1. To create a configfile in your current directory:
config -writeconf dosbox.conf
2. To set the cpu cycles to 10000:
config -set "cpu cycles=10000"
3. To turn ems memory emulation off:
config -set "dos ems=off"
4. To check which cpu core is being used.
config -get "cpu core"

Starting with version 0.65, DOSBox allows you to create movies out of screen
output.
To record a movie, you have to press CTRL-ALT-F5.
To stop/end the recording, you have to press CTRL-ALT-F5 again.
To play the recorded movie, you need a movie player which can handle the
ZMBV codec. MS Windows users can find this codec in the start menu entry of
DOSBox. Users of Linux and other OSes should look for a movie player that
uses the ffmpeg libary (you may need to update or ask your distribution to
upgrade).
FAQ:
Q: During the display of the movies the sound is lagging.
A: Check your display properties to see whether your refresh rate is set to
at least 70 hz. Try playing the movie in virtualdub (http://virtualdub.sf.net)
Q: Why does the resulting movie consist of multiple files?
A: Each time the game changes resolution, DOSBox creates a new movie file,
because a movie file can only contain one resolution.
Q: Can I set the cycles higher than my PC can handle during recording?
A: Yes. During recording, the game might play slowly and stuttering, but the
resulting movie should play at the intended speed and have no stuttering.
Q: CTRL-ALT-F5 switches to the console under linux.
A: 1. Start DOSBox like this: dosbox -startmapper
2. Click on Video, click on Add
3. Press the key you want (for example scroll lock or printscreen)
4. Click exit.
5. You can make movies by pressing scroll lock or whichever key you
selected.
