Q.   My game runs fine at first then an error message pops up on dosbox saying that the video file format is wrong. How or what can I do to fix this, if there is anything known?&lt;br /&gt;
&lt;br /&gt;
'''Q.''' My game/application runs slowly, how do I improve speed?&lt;br /&gt;
&lt;br /&gt;
'''A.''' Increase cycles. Use core=dynamic. Try different output modes (e.g. output=overlay). Increase Frameskip. Disable unneeded components in the [[dosbox.conf]] such as [[Sound]], mouse or joystick emulation. If all else fails, find a faster computer to run DOSBox on.&lt;br /&gt;
&lt;br /&gt;
Also be sure to check the compatibility section of this FAQ as some game/applications are more trouble (or resource hogs) than others.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
'''Q.''' The Sound/Music for my DOS game/application sounds terrible what can I do?&lt;br /&gt;
&lt;br /&gt;
'''A.''' This is a complicated issue covered in the [[Sound]] section of the wiki. It's important to remember to install or setup game/applications correctly to use the correct sound devices (&amp;lt;tt&amp;gt;INSTALL.EXE&amp;lt;/tt&amp;gt;, &amp;lt;tt&amp;gt;SOUNDSET.EXE&amp;lt;/tt&amp;gt; and &amp;lt;tt&amp;gt;SETUP.EXE&amp;lt;/tt&amp;gt; are popular program names to look for). The capabilities of the hardware as well as the preferences of the programmer vary: Therefore what may sound &amp;quot;best&amp;quot; on one particular game may not be the &amp;quot;best&amp;quot; for another. Sometimes changes need to be made to the [[dosbox.conf]] file (or a new conf file) to get the best results.&lt;br /&gt;
&lt;br /&gt;
Also, game sound/music may have an impact on the speed at which the game/application runs and running DOSBox with limited resources may result in incomplete or 'choppy' sound being heard. (see previous question)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Q. How do I change the memory size so that I can run programs that require more than the default settings (eg. Windows 1.01 or some other demanding OS)?&lt;br /&gt;
&lt;br /&gt;
= Usage =&lt;br /&gt;
'''Q.''' My backslash key is mapped to ']' with DOSBox in Vista. Is there a workaround?&lt;br /&gt;
&lt;br /&gt;
'''A.''' Press &amp;lt;tt&amp;gt;CTRL-F1&amp;lt;/tt&amp;gt; to enter the [[keymapper]] and select the backslash with your mouse. Press the &amp;lt;tt&amp;gt;DELETE&amp;lt;/tt&amp;gt; button that will show up on your screen. Then press &amp;lt;tt&amp;gt;ADD&amp;lt;/tt&amp;gt; to bind backslash to another key. Simply press an unused key to bind it to this. Press &amp;lt;tt&amp;gt;SAVE&amp;lt;/tt&amp;gt; and then &amp;lt;tt&amp;gt;EXIT&amp;lt;/tt&amp;gt; to return to the main screen.&lt;br /&gt;
&lt;br /&gt;
'''Q.''' My cursor is trapped within the DOSBox window when I click inside. How do I get the cursor out?&lt;br /&gt;
&lt;br /&gt;
'''A.''' DOSBox will capture your mouse when you click inside the display window (and you have '''&amp;lt;tt&amp;gt;autolock=true&amp;lt;/tt&amp;gt;''' set in the [[Dosbox.conf]]).  Simply press '''&amp;lt;tt&amp;gt;CTRL-F10&amp;lt;/tt&amp;gt;''' to release the mouse.&lt;br /&gt;
&lt;br /&gt;
'''Q.''' I have set Gnome to load DOSBox when I click on .COM files. How do I script it to exit DOSBox when I quit from the game?&lt;br /&gt;
&lt;br /&gt;
'''A.''' with -exit as commandline parameter for DOSBox.&lt;br /&gt;
&lt;br /&gt;
'''Q.''' How do I access my hard drive/cdrom in DOSBox?&lt;br /&gt;
&lt;br /&gt;
'''A.''' See the information on the [[MOUNT]] command, or type &amp;lt;tt&amp;gt;intro mount&amp;lt;/tt&amp;gt; or &amp;lt;tt&amp;gt;intro cdrom&amp;lt;/tt&amp;gt; in DOSBox for the basics.&lt;br /&gt;
&lt;br /&gt;
'''Q.''' I have an ISO image I made of files for backup purposes. How do I access it in DOSBox?&lt;br /&gt;
&lt;br /&gt;
'''A.''' See the information on the [[IMGMOUNT]] command&lt;br /&gt;
&lt;br /&gt;
'''Q.''' How do I unmount or change images? I need to swap CD images in the drive.&lt;br /&gt;
&lt;br /&gt;
'''A.''' You don't &amp;quot;unmount&amp;quot;, you may assign more than one image file to [[IMGMOUNT]], to swap images use &amp;lt;tt&amp;gt;CTRL-F4&amp;lt;/tt&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
'''Q.''' I have created an image from a CD that includes CD audio tracks, when I access it in DOSBox only the first (data) track is available.&lt;br /&gt;
&lt;br /&gt;
'''A.''' Be sure to use the bin/cue format for mixed mode CDs (CDs with a data and audio tracks) and always pass the cue file to [[IMGMOUNT]].&lt;br /&gt;
&lt;br /&gt;
'''Q.''' I can't find the &amp;quot;:&amp;quot; symbol anywhere in my dosbox. I am using ista on a laptop. Please advice me how to fix the problem.&lt;/div&gt;</summary>
