Setup DOSBox to emulate a specific type of machine. Valid choices are: hercules, cga, ega, pcjr, tandy, svgas3 (default) as well as the additional svga chipsets listed in the DOSBox configuration file. Svgas3 enables vesa emulation as well. After a while the serial port is set back to following: 19603 14:54:23 DOSBox.exe IOCTLSERIALSETBAUDRATE Serial0 SUCCESS Rate: 9600 19604 14:54:23 DOSBox.exe IOCTLSERIALCLRRTS Serial0 SUCCESS 19605 14:54:23 DOSBox.exe IOCTLSERIALCLRDTR Serial0 SUCCESS 19606 14:54:23 DOSBox.exe IOCTLSERIALSETLINECONTROL Serial0 SUCCESS StopBits: 1. Many USB serial ports do not support a 5 bits per byte configuration however when configuring a serial port under DOS it is fairly common practice to simply set the serial ports LCR register to 0x80 to set the DLAB bit before setting the LCR to the. Setting up real serial port to dosbox macos. I’m trying to read data from an arduino to tasm running on dos box I’ve read that I need to set up the serial port in the dosbox preferences like this: serial1=directserial realport:COM1.

While we are hoping that one day DOSBox will run all programs ever made for the PC, we are not there yet.
At present, DOSBox running on a high-end machine will roughly bethe equivalent of a Pentium I PC. DOSBox can be configured to run a wide range of DOS games, from CGA/Tandy/PCjr classics up to games from the Quake era. INDEX: 1. Quickstart:
Type INTRO in DOSBox for a quick tour. It is essential that you get familiar with the idea of mounting, DOSBox does not automatically make any drive (or a part of it) accessible to the emulation. See the FAQ entry ’How to start?’ as well as the description of the MOUNT command (section 4: ’Internal Programs’). If you have your game on a cdrom you may try this guide: https://www.vogons.org/viewtopic.php?t=8933 2.

Great Manual, but I still don’t get it.START: How to start?
At the beginning you’ve got a Z:> instead of a C:> at the prompt. You have to make your directories available as drives in DOSBox by using the ’mount’ command. For example, in Windows ’mount C D:GAMES’ will give you a C drive in DOSBox which points to your Windows D:GAMES directory (that was created before). In Linux, ’mount c /home/username’ will give you a C drive in DOSBox which points to /home/username in Linux. To change to the drive mounted like above, type ’C:’. If everything went fine, DOSBox will display the prompt ’C:>’. AUTOMATION: Do I always have to type these commands?
In the DOSBox configuration file is an [autoexec] section. The commands present there are run when DOSBox starts, so you can use this section for the mounting. Look at Section 13: The configuration (options) file FULLSCREEN: How do I change to fullscreen?
Press alt-enter. Alternatively: Edit the configuration file of DOSBox and change the option fullscreen=false to fullscreen=true. If fullscreen looks wrong in your opinion: Play with the options: fullresolution, output and aspect in the configuration file of DOSBox. To get back from fullscreen mode: Press alt-enter again. FULLSCREEN: My fullscreen is too large.
This is can be a problem on Windows 10, if you have display scaling set to a value above 100%. Windows in that case will resize the screen on top of dosbox resizing the screen, which can happen for the output: ddraw, opengl, openglnb, overlay. You can disable this Windows behaviour by enabling a specific compatibility setting:
- Right-click the DOSBox icon and select ’Properties’.- Go to the ’Compatibility’ tab.- Click on ’Change high DPI settings’.- Tick ’Override high DPI scaling behaviour’ and set it to ’Application’.- Apply the changes by clicking on ’OK’.
Unfortunately, this compatibility option causes some side effects in windowed mode, and in this case you will need to change the resolution in the config/Options file for windowresolution (e.g. 1024x768).
Alternatively, you can disable the display scaling and or use a lower fullresolution value.CD-ROM: My CD-ROM doesn’t work.
To mount your CD-ROM in DOSBox you have to specify some additional options when mounting the CD-ROM. To enable CD-ROM support (includes MSCDEX) in Windows:
- mount d f: -t cdrom
in Linux:
- mount d /media/cdrom -t cdrom
In some cases you might want to use a different CD-ROM interface, for example if CD audio does not work:
To enable SDL-support (does not include low-level CD access!):
- mount d f: -t cdrom -usecd 0 -noioctl
To enable ioctl access using digital audio extraction for CD audio (windows-only, useful for Vista):
- mount d f: -t cdrom -ioctl_dx
To enable ioctl access using MCI for CD audio (windows-only):
- mount d f: -t cdrom -ioctl_mci
To force ioctl-only access (windows-only):
- mount d f: -t cdrom -ioctl_dio
To enable low-level aspi-support (win98 with aspi-layer installed):
- mount d f: -t cdrom -aspi
explanation:
- d driveletter you will get in DOSBox (d is the best, don’t change it!)
- f: location of CD-ROM on your PC. In most cases it will be d: or e: - 0 The number of the CD-ROM drive, reported by ’mount -cd’
(note that this value is only needed when using SDL for CD audio,
otherwise it is ignored)
See also the next question: The game/application can’t find its CD-ROM. CD-ROM: The game/application can’t find its CD-ROM
Be sure to mount the CD-ROM with -t cdrom switch, this will enable the MSCDEX interface required by DOS games to interface with CD-ROMs. Also try adding the correct label (-label LABEL) to the mount command, where LABEL is the CD-label (volume ID) of the CD-ROM. Under Windows you can specify -ioctl, -aspi or -noioctl. Look at the description of the mount command in Section 4: ’Internal programs’ for their meaning and the additional audio-CD related options -ioctl_dx, -ioctl_mci, -ioctl_dio. Try creating a CD-ROM image (preferably CUE/BIN pair) and use the DOSBox’s internal IMGMOUNT tool to mount the image (the CUE sheet). This enables very good low-level CD-ROM support on any operating system. MOUSE: The mouse doesn’t work.
Usually, DOSBox detects when a game uses mouse control. When you click on the screen it should get locked (confined to the DOSBox window) and work. With certain games, the DOSBox mouse detection doesn’t work. In that case you will have to lock the mouse manually by pressing CTRL-F10. SOUND: There is no sound
Be sure that the sound is correctly configured in the game. This might be done during the installation or with a setup/setsound utility that accompanies the game. First see if an autodetection option is provided. If there is none try selecting Soundblaster or Soundblaster 16 with the default settings being ’address=220 irq=7 dma=1’ (sometimes highdma=5). You might also want to select Sound Canvas/SCC/MPU-401/General MIDI/Wave Blaster at ’address=330 IRQ=2’ as music device. The parameters of the emulated sound cards can be changed in the DOSBox configuration file.
If you still don’t get any sound set the core to normal in DOSBox configuration and use some lower fixed cycles value (like cycles=2000). Also assure that your host operating sound does provide sound. In certain cases it might be useful to use a different emulated sound device like a soundblaster pro (sbtype=sbpro1 in the DOSBox configuration file) or the gravis ultrasound (gus=true). SOUND: What sound hardware does DOSBox presently emulate?
DOSBox emulates several legacy sound devices:
*Internal PC speaker/Buzzer This emulation includes both the tone generator and several forms of digital sound output through the internal speaker.
*Creative CMS/Gameblaster The is the first card released by Creative Labs(R). The default configuration places it on address 220. It is disabled as default.
*Tandy 3 voice The emulation of this sound hardware is complete with the exception of the noise channel. The noise channel is not very well documented and as such is only a best guess as to the sound’s accuracy. It is disabled as default.
*Tandy DAC Some games may require turning off sound blaster emulation (sbtype=none) for better tandy DAC sound support. Don’t forget to set the sbtype back to sb16 if you don’t use tandy sound.
*Adlib This emulation is almost perfect and includes the Adlib’s ability to almost play digitized sound. Placed at address 220 (also on 388).
*SoundBlaster 16 / SoundBlaster Pro I & II / SoundBlaster I & II By default DOSBox provides Soundblaster 16 level 16-bit stereo sound. You can select a different SoundBlaster version in the configuration of DOSBox. AWE32 music is not emulated as you can use MPU-401 instead (see below).
*Disney Sound Source and Covox Speech Thing Using the printer port, this sound device outputs digital sound only. Placed at LPT1
*Gravis Ultrasound The emulation of this hardware is nearly complete, though the MIDI capabilities have been left out, since an MPU-401 has been emulated in other code. For Gravis music you also have to install Gravis drivers inside DOSBox. It is disabled as default.
*MPU-401 A MIDI passthrough interface is also emulated. This method of sound output will only work when used with external device/emulator. Every Windows XP/Vista/7 and MAC OS has got a default emulator compatible with: Sound Canvas/SCC/General Standard/General MIDI/Wave Blaster. A different device/emulator is needed for Roland LAPC/CM-32L/MT-32 compatibility. SOUND: The sound stutters or sounds stretched/weird.
You may be using too much CPU power to keep DOSBox running at the current speed. You can lower the cycles, skip frames, reduce the sampling rate of the respective sound device, increase the prebuffer. See section 13: ’The configuration (options) file’ If you are using cycles=max or =auto, then make sure that there is no background processes interfering! (especially if they access the harddisk) Also look at Section 10. ’How to speed up/slow down DOSBox’ KEYBOARD: I can’t type or : in DOSBox.
This can happen in various cases, like your host keyboard layout does not have a matching DOS layout representation (or it was not correctly detected), or the key mapping is wrong. Some possible fixes:
*Use / instead, or ALT-58 for : and ALT-92 for .
*Change the DOS keyboard layout (see Section 8: Keyboard Layout).
*Add the commands you want to execute to the [autoexec] section of the DOSBox configuration file.
*Open the DOSBox configuration file and change the usescancodes entry.
*Switch the keyboard layout of your operating system.
Note that if the host layout can not be identified, or keyboardlayout is set to none in the DOSBox configuration file, the standard US layout is used. In this configuration try the keys around ’enter’ for the key (backslash), and for the key : (colon) use shift and the keys between ’enter’ and ’L’. KEYBOARD: Right Shift and ’ doesn’t work in DOSBox. (Windows only)
This may happen if Windows thinks that you have more than one keyboard connected to your PC when you use some remote control devices. To verity this problem run cmd.exe, navigate to DOSBox program folder and type:
set sdl_videodriver=windib dosbox.exe
check whether keyboard started to work properly. As windib is slower it is best to use one of the two solutions provided here: https://www.vogons.org/viewtopic.php?t=24072 KEYBOARD: The keyboard lags
Lower the priority setting in the DOSBox configuration file, for example set ’priority=normal,normal’. You might also want to try lowering the cycles (use a fixed cycle amount to start with, like cycles=10000). CONTROL: The character/cursor/mouse pointer always moves into one direction!
See if it still happens if you disable the joystick emulation, set joysticktype=none in the [joystick] section of your DOSBox configuration file. Maybe also try unplugging any joystick/gamepad. If you want to use the joystick in the game, try setting timed=false and be sure to calibrate the joystick (both in your OS as well as in the game or the game’s setup program). SPEED: The game/application runs much too slow/too fast!
Look at Section 10: ’How to speed up/slow down DOSBox’ for more information. CRASH: The game/application does not run at all/crashes!
Look at Section 11: Troubleshooting CRASH: DOSBox crashes on startup!
Look at Section 11: Troubleshooting GAME: My Build game(Duke3D/Blood/Shadow Warrior) has problems
First of all, try to find a port of the game. Those will offer a better experience. To fix the graphics problem that occurs in DOSBox on higher resolutions: Open the configuration file of DOSBox and search for:
machine=svga_s3. Change svga_s3 to vesa_nolfb Change memsize=16 to memsize=63 SAFETY: Can DOSBox harm my computer?
DOSBox can not harm your computer more than any other resource demanding program. Increasing the cycles does not overclock your real CPU. Setting the cycles too high has a negative performance effect on the software running inside DOSBox. OPTIONS: I would like to change DOSBox’s options.

An overview of the command line options you can give to DOSBox. Although in most cases it is easier to use DOSBox’s configuration file instead. See: Section 13. ’The configuration (options) file’
To be able to use Command Line Parameters: (Windows) open cmd.exe or command.com or edit the shortcut to dosbox.exe (Linux) use console (MAC OS X) start terminal.app and navigate to:
/applications/dosbox.app/contents/macos/dosbox
The options are valid for all operating systems unless noted in the option description:
dosbox [name] [-exit] [-c command] [-fullscreen] [-userconf]
[-conf congfigfilelocation] [-lang languagefilelocation] [-machine machine type] [-noconsole] [-startmapper] [-noautoexec] [-securemode] [-scaler scaler | -forcescaler scaler] [-version] [-socket socket]
dosbox -version dosbox -editconf program dosbox -opencaptures program dosbox -printconf dosbox -eraseconf dosbox -erasemapper
name
If ’name’ is a directory it will mount that as the C: drive. If ’name’ is an executable it will mount the directory of ’name’ as the C: drive and execute ’name’.
-exit
DOSBox will close itself when the DOS application ’name’ ends.
-c command
Runs the specified command before running ’name’. Multiple commands can be specified. Each command should start with ’-c’ though. A command can be: an Internal Program, a DOS command or an executable on a mounted drive.
-fullscreen
Starts DOSBox in fullscreen mode.
-userconf
Start DOSBox with the users specific configuration file. Can be used together with multiple -conf parameters, but -userconf will always be loaded before them.
-conf configfilelocation
Start DOSBox with the options specified in ’configfilelocation’. Multiple -conf options may be present. See Section 13 for more details.
-lang languagefilelocation
Start DOSBox using the language specified in ’languagefilelocation’. See Section 14 for more details.
-machine machinetype
Setup DOSBox to emulate a specific type of machine. Valid choices are: hercules, cga, ega, pcjr, tandy, svga_s3 (default) as well as the additional svga chipsets listed in the DOSBox configuration file. svga_s3 enables vesa emulation as well. For some special vga effects the machinetype vgaonly can be used, note that this disables svga capabilities and might be slower due to the higher emulation precision. The machinetype affects the video card and the available sound cards.
-noconsole (Windows Only)
Start DOSBox without showing DOSBox Status Window (console). Output will be redirected to stdout.txt and stderr.txt
-startmapper
Enter the keymapper directly on startup. Useful for people with keyboard problems.
-noautoexec
Skips the [autoexec] section of the loaded configuration file.
-securemode
Same as -noautoexec, but adds config.com -securemode at the bottom of AUTOEXEC.BAT (which in turn disables any changes to how the drives are mounted inside DOSBox).
-scaler scaler
Uses the scaler specified by ’scaler’. See the DOSBox configuration file for the available scalers.
-forcescaler scaler
Similar to the -scaler parameter, but tries to force usage of the specified scaler even if it might not fit.
-version
output version information and exit. Useful for frontends.
-editconf program
calls program with as first parameter the configuration file. You can specify this command more than once. In this case it will move to second program if the first one fails to start.
-opencaptures program
calls program with as first parameter the location of the captures folder.
-printconf
prints the location of the default configuration file.
-resetconf
removes the default configuration file.
-resetmapper
removes the mapperfile used by the default clean configuration file.
-socket
passes the socket number to the nullmodem emulation. See Section 9: ’Serial Multiplayer feature.’
Note:
If a name/command/configfilelocation/languagefilelocation contains a space, put the whole name/command/configfilelocation/languagefilelocation between quotes (’command or file name’). If you need to use quotes within quotes (most likely with -c and mount): Windows and OS/2 users can use single quotes inside the double quotes. Other people should be able to use escaped double quotes inside the double quotes. Windows: -c ’mount c ’c:My folder with DOS games’ Linux: -c ’mount c ’/tmp/name with space’

Great Manual, but I still don’t get it.START: How to start?
At the beginning you’ve got a Z:> instead of a C:> at the prompt. You have to make your directories available as drives in DOSBox by using the ’mount’ command. For example, in Windows ’mount C D:GAMES’ will give you a C drive in DOSBox which points to your Windows D:GAMES directory (that was created before). In Linux, ’mount c /home/username’ will give you a C drive in DOSBox which points to /home/username in Linux. To change to the drive mounted like above, type ’C:’. If everything went fine, DOSBox will display the prompt ’C:>’. AUTOMATION: Do I always have to type these commands?
In the DOSBox configuration file is an [autoexec] section. The commands present there are run when DOSBox starts, so you can use this section for the mounting. Look at Section 13: The configuration (options) file FULLSCREEN: How do I change to fullscreen?
Press alt-enter. Alternatively: Edit the configuration file of DOSBox and change the option fullscreen=false to fullscreen=true. If fullscreen looks wrong in your opinion: Play with the options: fullresolution, output and aspect in the configuration file of DOSBox. To get back from fullscreen mode: Press alt-enter again. FULLSCREEN: My fullscreen is too large.
This is can be a problem on Windows 10, if you have display scaling set to a value above 100%. Windows in that case will resize the screen on top of dosbox resizing the screen, which can happen for the output: ddraw, opengl, openglnb, overlay. You can disable this Windows behaviour by enabling a specific compatibility setting:
- Right-click the DOSBox icon and select ’Properties’.- Go to the ’Compatibility’ tab.- Click on ’Change high DPI settings’.- Tick ’Override high DPI scaling behaviour’ and set it to ’Application’.- Apply the changes by clicking on ’OK’.
Unfortunately, this compatibility option causes some side effects in windowed mode, and in this case you will need to change the resolution in the config/Options file for windowresolution (e.g. 1024x768).
Alternatively, you can disable the display scaling and or use a lower fullresolution value.CD-ROM: My CD-ROM doesn’t work.
To mount your CD-ROM in DOSBox you have to specify some additional options when mounting the CD-ROM. To enable CD-ROM support (includes MSCDEX) in Windows:
- mount d f: -t cdrom
in Linux:
- mount d /media/cdrom -t cdrom
In some cases you might want to use a different CD-ROM interface, for example if CD audio does not work:
To enable SDL-support (does not include low-level CD access!):
- mount d f: -t cdrom -usecd 0 -noioctl
To enable ioctl access using digital audio extraction for CD audio (windows-only, useful for Vista):
- mount d f: -t cdrom -ioctl_dx
To enable ioctl access using MCI for CD audio (windows-only):
- mount d f: -t cdrom -ioctl_mci
To force ioctl-only access (windows-only):
- mount d f: -t cdrom -ioctl_dio
To enable low-level aspi-support (win98 with aspi-layer installed):
- mount d f: -t cdrom -aspi
explanation:
- d driveletter you will get in DOSBox (d is the best, don’t change it!)
- f: location of CD-ROM on your PC. In most cases it will be d: or e: - 0 The number of the CD-ROM drive, reported by ’mount -cd’
(note that this value is only needed when using SDL for CD audio,
otherwise it is ignored)
See also the next question: The game/application can’t find its CD-ROM. CD-ROM: The game/application can’t find its CD-ROM
Be sure to mount the CD-ROM with -t cdrom switch, this will enable the MSCDEX interface required by DOS games to interface with CD-ROMs. Also try adding the correct label (-label LABEL) to the mount command, where LABEL is the CD-label (volume ID) of the CD-ROM. Under Windows you can specify -ioctl, -aspi or -noioctl. Look at the description of the mount command in Section 4: ’Internal programs’ for their meaning and the additional audio-CD related options -ioctl_dx, -ioctl_mci, -ioctl_dio. Try creating a CD-ROM image (preferably CUE/BIN pair) and use the DOSBox’s internal IMGMOUNT tool to mount the image (the CUE sheet). This enables very good low-level CD-ROM support on any operating system. MOUSE: The mouse doesn’t work.
Usually, DOSBox detects when a game uses mouse control. When you click on the screen it should get locked (confined to the DOSBox window) and work. With certain games, the DOSBox mouse detection doesn’t work. In that case you will have to lock the mouse manually by pressing CTRL-F10. SOUND: There is no sound
Be sure that the sound is correctly configured in the game. This might be done during the installation or with a setup/setsound utility that accompanies the game. First see if an autodetection option is provided. If there is none try selecting Soundblaster or Soundblaster 16 with the default settings being ’address=220 irq=7 dma=1’ (sometimes highdma=5). You might also want to select Sound Canvas/SCC/MPU-401/General MIDI/Wave Blaster at ’address=330 IRQ=2’ as music device. The parameters of the emulated sound cards can be changed in the DOSBox configuration file.
If you still don’t get any sound set the core to normal in DOSBox configuration and use some lower fixed cycles value (like cycles=2000). Also assure that your host operating sound does provide sound. In certain cases it might be useful to use a different emulated sound device like a soundblaster pro (sbtype=sbpro1 in the DOSBox configuration file) or the gravis ultrasound (gus=true). SOUND: What sound hardware does DOSBox presently emulate?
DOSBox emulates several legacy sound devices:
*Internal PC speaker/Buzzer This emulation includes both the tone generator and several forms of digital sound output through the internal speaker.
*Creative CMS/Gameblaster The is the first card released by Creative Labs(R). The default configuration places it on address 220. It is disabled as default.
*Tandy 3 voice The emulation of this sound hardware is complete with the exception of the noise channel. The noise channel is not very well documented and as such is only a best guess as to the sound’s accuracy. It is disabled as default.
*Tandy DAC Some games may require turning off sound blaster emulation (sbtype=none) for better tandy DAC sound support. Don’t forget to set the sbtype back to sb16 if you don’t use tandy sound.
*Adlib This emulation is almost perfect and includes the Adlib’s ability to almost play digitized sound. Placed at address 220 (also on 388).
*SoundBlaster 16 / SoundBlaster Pro I & II / SoundBlaster I & II By default DOSBox provides Soundblaster 16 level 16-bit stereo sound. You can select a different SoundBlaster version in the configuration of DOSBox. AWE32 music is not emulated as you can use MPU-401 instead (see below).
*Disney Sound Source and Covox Speech Thing Using the printer port, this sound device outputs digital sound only. Placed at LPT1
*Gravis Ultrasound The emulation of this hardware is nearly complete, though the MIDI capabilities have been left out, since an MPU-401 has been emulated in other code. For Gravis music you also have to install Gravis drivers inside DOSBox. It is disabled as default.
*MPU-401 A MIDI passthrough interface is also emulated. This method of sound output will only work when used with external device/emulator. Every Windows XP/Vista/7 and MAC OS has got a default emulator compatible with: Sound Canvas/SCC/General Standard/General MIDI/Wave Blaster. A different device/emulator is needed for Roland LAPC/CM-32L/MT-32 compatibility. SOUND: The sound stutters or sounds stretched/weird.
You may be using too much CPU power to keep DOSBox running at the current speed. You can lower the cycles, skip frames, reduce the sampling rate of the respective sound device, increase the prebuffer. See section 13: ’The configuration (options) file’ If you are using cycles=max or =auto, then make sure that there is no background processes interfering! (especially if they access the harddisk) Also look at Section 10. ’How to speed up/slow down DOSBox’ KEYBOARD: I can’t type or : in DOSBox.
This can happen in various cases, like your host keyboard layout does not have a matching DOS layout representation (or it was not correctly detected), or the key mapping is wrong. Some possible fixes:
*Use / instead, or ALT-58 for : and ALT-92 for .
*Change the DOS keyboard layout (see Section 8: Keyboard Layout).
*Add the commands you want to execute to the [autoexec] section of the DOSBox configuration file.
*Open the DOSBox configuration file and change the usescancodes entry.
*Switch the keyboard layout of your operating system.
Note that if the host layout can not be identified, or keyboardlayout is set to none in the DOSBox configuration file, the standard US layout is used. In this configuration try the keys around ’enter’ for the key (backslash), and for the key : (colon) use shift and the keys between ’enter’ and ’L’. KEYBOARD: Right Shift and ’ doesn’t work in DOSBox. (Windows only)
This may happen if Windows thinks that you have more than one keyboard connected to your PC when you use some remote control devices. To verity this problem run cmd.exe, navigate to DOSBox program folder and type:
set sdl_videodriver=windib dosbox.exe
check whether keyboard started to work properly. As windib is slower it is best to use one of the two solutions provided here: https://www.vogons.org/viewtopic.php?t=24072 KEYBOARD: The keyboard lags
Lower the priority setting in the DOSBox configuration file, for example set ’priority=normal,normal’. You might also want to try lowering the cycles (use a fixed cycle amount to start with, like cycles=10000). CONTROL: The character/cursor/mouse pointer always moves into one direction!
See if it still happens if you disable the joystick emulation, set joysticktype=none in the [joystick] section of your DOSBox configuration file. Maybe also try unplugging any joystick/gamepad. If you want to use the joystick in the game, try setting timed=false and be sure to calibrate the joystick (both in your OS as well as in the game or the game’s setup program). SPEED: The game/application runs much too slow/too fast!
Look at Section 10: ’How to speed up/slow down DOSBox’ for more information. CRASH: The game/application does not run at all/crashes!
Look at Section 11: Troubleshooting CRASH: DOSBox crashes on startup!
Look at Section 11: Troubleshooting GAME: My Build game(Duke3D/Blood/Shadow Warrior) has problems
First of all, try to find a port of the game. Those will offer a better experience. To fix the graphics problem that occurs in DOSBox on higher resolutions: Open the configuration file of DOSBox and search for:
machine=svga_s3. Change svga_s3 to vesa_nolfb Change memsize=16 to memsize=63 SAFETY: Can DOSBox harm my computer?
DOSBox can not harm your computer more than any other resource demanding program. Increasing the cycles does not overclock your real CPU. Setting the cycles too high has a negative performance effect on the software running inside DOSBox. OPTIONS: I would like to change DOSBox’s options.
Look at Section 13. ’The configuration (options) file’ HELP: Great Manual, but I still don’t get it

An overview of the command line options you can give to DOSBox. Although in most cases it is easier to use DOSBox’s configuration file instead. See: Section 13. ’The configuration (options) file’
To be able to use Command Line Parameters: (Windows) open cmd.exe or command.com or edit the shortcut to dosbox.exe (Linux) use console (MAC OS X) start terminal.app and navigate to:
/applications/dosbox.app/contents/macos/dosbox
The options are valid for all operating systems unless noted in the option description:
dosbox [name] [-exit] [-c command] [-fullscreen] [-userconf]
[-conf congfigfilelocation] [-lang languagefilelocation] [-machine machine type] [-noconsole] [-startmapper] [-noautoexec] [-securemode] [-scaler scaler | -forcescaler scaler] [-version] [-socket socket]
dosbox -version dosbox -editconf program dosbox -opencaptures program dosbox -printconf dosbox -eraseconf dosbox -erasemapper
name
If ’name’ is a directory it will mount that as the C: drive. If ’name’ is an executable it will mount the directory of ’name’ as the C: drive and execute ’name’.
-exit
DOSBox will close itself when the DOS application ’name’ ends.
-c command
Runs the specified command before running ’name’. Multiple commands can be specified. Each command should start with ’-c’ though. A command can be: an Internal Program, a DOS command or an executable on a mounted drive.
-fullscreen
Starts DOSBox in fullscreen mode.
-userconf
Start DOSBox with the users specific configuration file. Can be used together with multiple -conf parameters, but -userconf will always be loaded before them.
-conf configfilelocation
Start DOSBox with the options specified in ’configfilelocation’. Multiple -conf options may be present. See Section 13 for more details.
-lang languagefilelocation
Start DOSBox using the language specified in ’languagefilelocation’. See Section 14 for more details.
-machine machinetype
Setup DOSBox to emulate a specific type of machine. Valid choices are: hercules, cga, ega, pcjr, tandy, svga_s3 (default) as well as the additional svga chipsets listed in the DOSBox configuration file. svga_s3 enables vesa emulation as well. For some special vga effects the machinetype vgaonly can be used, note that this disables svga capabilities and might be slower due to the higher emulation precision. The machinetype affects the video card and the available sound cards.
-noconsole (Windows Only)
Start DOSBox without showing DOSBox Status Window (console). Output will be redirected to stdout.txt and stderr.txt
-startmapper
Enter the keymapper directly on startup. Useful for people with keyboard problems.
-noautoexec
Skips the [autoexec] section of the loaded configuration file.
-securemode
Same as -noautoexec, but adds config.com -securemode at the bottom of AUTOEXEC.BAT (which in turn disables any changes to how the drives are mounted inside DOSBox).
-scaler scaler
Uses the scaler specified by ’scaler’. See the DOSBox configuration file for the available scalers.
-forcescaler scaler
Similar to the -scaler parameter, but tries to force usage of the specified scaler even if it might not fit.
-version
output version information and exit. Useful for frontends.
-editconf program
calls program with as first parameter the configuration file. You can specify this command more than once. In this case it will move to second program if the first one fails to start.
-opencaptures program
calls program with as first parameter the location of the captures folder.
-printconf
prints the location of the default configuration file.
-resetconf
removes the default configuration file.
-resetmapper
removes the mapperfile used by the default clean configuration file.
-socket
passes the socket number to the nullmodem emulation. See Section 9: ’Serial Multiplayer feature.’
Note:
If a name/command/configfilelocation/languagefilelocation contains a space, put the whole name/command/configfilelocation/languagefilelocation between quotes (’command or file name’). If you need to use quotes within quotes (most likely with -c and mount): Windows and OS/2 users can use single quotes inside the double quotes. Other people should be able to use escaped double quotes inside the double quotes. Windows: -c ’mount c ’c:My folder with DOS games’ Linux: -c ’mount c ’/tmp/name with space’
A rather unusual example, just to demonstrate what yo
