DOSBox v0.62
|
||
|
||
|
||
=====
|
||
NOTE:
|
||
=====
|
||
|
||
While we hope that, one day, DOSBox will run virtually all programs
|
||
ever made for the PC...we are not there yet. At present, DOSBox run on a high-
|
||
end machine will roughly be the equivalent of a 486 PC. The 0.60
|
||
release has added support for "protected mode" allowing for more complex and
|
||
recent programs, but note that this support is early in development and
|
||
nowhere near as complete as the support for 386 real-mode games (or
|
||
earlier). Also note that "protected mode" games need substantially more
|
||
resources and may require a much faster processor for you to run it properly
|
||
in DOSBox.

Some Frequently Asked Questions:
|
||
|
||
Q: I've got a Z instead of a C at the prompt.
|
||
Q: My CD-ROM doesn't work.
|
||
Q: The mouse doesn't work.
|
||
Q: The sound stutters.
|
||
Q: I can't type \ or : in DOSBox.
|
||
Q: The game/application can't find its CD-ROM.
|
||
Q: The game/application runs much too slow!
|
||
Q: I would like to change the memory size/cpu speed/ems/soundblaster IRQ.
|
||
Q: What sound hardware does DOSBox presently emulate?
|
||
|
||
|
||
|
||
|
||
|
||
|
||
Q: I've got a Z instead of a C at the prompt.
|
||
A: You have to make your directories available as drives in DOSBox by using
|
||
the "mount" command. For example, in Windows "mount C D:\" would give
|
||
you a C in DOSBox which points at your Windows D:\ drive.
|
||
In Linux, "mount c /home/username" would give you a C in DOSBox
|
||
which points at /home/username in Linux.
|
||
|
||
|
||
Q: My CD-ROM doesn't work.
|
||
A: To mount your cdrom in DOSBox you have to specify some additional options
|
||
when mounting the cdrom.
|
||
To enable the most basic cdrom support:
|
||
- mount d f:\ -t cdrom
|
||
To enable low-level SDL-support:
|
||
- mount d f:\ -t cdrom -usecd 0
|
||
To enable low-level ioctl-support(win2k/xp/linux):
|
||
- mount d f:\ -t cdrom -usecd 0 -ioctl
|
||
To enable low-level aspi-support (win98 with aspi-layer installed):
|
||
- mount d f:\ -t cdrom -usecd 0 -apsi
|
||
|
||
In the commands: - d driveletter you in DOSBox
|
||
- f:\ location of cdrom on your PC.
|
||
- 0 The number of the cdrom drive, reported by mount -cd
|
||
See also the question: The game/application can't find its CD-ROM.
|
||
|
||
|
||
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 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.
|
||
|
||
|
||
Q: The sound stutters.
|
||
A: You're using too much cpu power to keep DOSBox running at the current speed.
|
||
You can either lower the cycles or skip frames or get a faster machine.
|
||
You can also increase the prebuffer in the configfile
|
||
|
||
|
||
Q: I can't type \ or : in DOSBox.
|
||
A: This is a known problem. It only occurs if your keyboard layout isn't US.
|
||
Some possible fixes:
|
||
1. Switch your keyboard layout.
|
||
2. Use / instead.
|
||
3. Add the commands you want to execute to dosbox.conf
|
||
4. Start the keymapper (CTRL-F1 or add -startmapper switch to dosbox)
|
||
5. for \ try the keys around "enter". For ":" try shift and the keys between
|
||
"enter" and "l" (US keyboard layout).
|
||
6. Use keyb.com for FreeDOS (http://projects.freedos.net/keyb/).
|
||
|
||
|
||
Q: The game/application can't find its CD-ROM.
|
||
A: Be sure to mount the CD-ROM with -t cdrom switch. Also try adding the
|
||
correct label (-label LABEL). To enable more low-level CD-ROM support add
|
||
the following switch to mount: -usecd #, where # is the number of your
|
||
CD-ROM drive reported by mount -cd. If you run Win32 you can specify -ioctl
|
||
or -aspi. Look at the description elsewhere in this document for their
|
||
meaning.
|
||
|
||
|
||
Q: The game/application runs much too slow!
|
||
A: Look at the section "To run resource-demanding games" for more information.
|
||
|
||
|
||
Q: I would like to change the memory size/cpu speed/ems/soundblaster IRQ.
|
||
A: This is possible! Just create a config file: config -writeconf dosbox.conf .
|
||
Start your favourite editor and look at all the settings present. To
|
||
start DOSBox with your new settings: dosbox -conf dosbox.conf
|
||
|
||
|
||
Q: What sound hardware does DOSBox presently emulate?
|
||
A: DOSBox emulates several legacy sound devices:
|
||
- Internal PC speaker
|
||
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 port 0x220. It should be noted that enabling
|
||
this with the Adlib emulation may result in conflicts.
|
||
- Tandy 3 voice
|
||
The emulation of this sound hardware is complete with the exception of
|
||
the noise channel, which is not very well documented and as such is only
|
||
a best guess as to the sound's accuracy.
|
||
- Adlib
|
||
Borrowed from MAME, this emulation is almost perfect and includes the
|
||
Adlib's ability to almost play digitized sound.
|
||
- SoundBlaster Pro
|
||
Coupled with the Adlib, DOSBox provides Soundblaster Pro level 8-bit
|
||
stereo sound.
|
||
- Disney Soundsource
|
||
Using the printer port, this sound device outputs digital sound only.
|
||
- 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.
|
||
- MPU-401
|
||
A MIDI passthrough interface is also emulated. This method of sound
|
||
output will only work when used with a General Midi or MT-32 device.
|
||
|
||
|
||
Q: Great README, but I still don't get it.
|
||
A: While unlikely, this seems to happen. A look at "The Newbie's
|
||
pictorial guide to DOSBox" located at
|
||
http://vogons.zetafleet.com/viewforum.php?f=39 might help you.
|
||
|
||

3. Usage:
|
||
=========
|
||
|
||
An overview of the commandline options you can give to DOSBox:
|
||
|
||
dosbox [name] [-exit] [-c command] [-fullscreen] [-conf congfigfile]
|
||
[-lang languagefile] [-machine machinetype] [-noconsole]
|
||
[-startmapper]
|
||
|
||
dosbox -version
|
||
|
||
name
|
||
If "name" is a directory it'll mount that as the C: drive.
|
||
If "name" is an executable it'll mount the directory of "name"
|
||
as the C: drive and execute "name".
|
||
|
||
-exit
|
||
dosbox will exit after the "name" has been executed.
|
||
|
||
-c command
|
||
Runs the specified command before running "name". Multiple commands
|
||
can be specified. Each command should start with -c though.
|
||
|
||
-fullscreen
|
||
Starts dosbox in fullscreen mode.
|
||
|
||
-conf configfile
|
||
Start dosbox with the options specified in "configfile".
|
||
|
||
-lang languagefile
|
||
Start dosbox using the language string specified in "languagefile".
|
||
|
||
-noconsole (Windows Only)
|
||
Start dosbox without showing the console window. Output will
|
||
be redirected to stdout.txt and stderr.txt
|
||
|
||
-machine machinetype
|
||
Setup dosbox to emulate a specific type of machine. Valid choices are:
|
||
hercules, cga, tandy, vga (default).
|
||
|
||
-startmapper
|
||
Enter the keymapper directly on startup. Useful for people with
|
||
keyboard problems.
|
||
|
||
-version
|
||
output version information and exit. Useful for frontends.
|
||
|
||
Note: If a name/command/configfile/languagefile contains a space in it, put
|
||
the whole name/command/configfile/languagefile between quotes("example").
|
||
|
||
For example:
|
||
|
||
dosbox c:\atlantis\atlantis.exe -c "MOUNT D C:\SAVES"
|
||
This would mount c:\atlantis as c:\ and run atlantis.exe.
|
||
Before it does that it would first mount C:\SAVES as the D drive.
|
||
|
||
In Windows you can also drag directories/files onto the dosbox executable.
|
||
|
||
|
||
|
||
=====================
|
||
4. Internal Programs:
|
||
=====================
|
||
|
||
DOSBox supports most of the DOS commands found in command.com.
|
||
In addition, the following commands are available:
|
||
|
||
MOUNT "Emulated Drive letter" "Real Drive or Directory"
|
||
[-t type] [-aspi] [-ioctl] [-usecd number] [-size drivesize]
|
||
[-label drivelabel] [-freesize sizemb]
|
||
MOUNT -cd
|
||
|
||
Program to mount local directories as drives inside DOSBox.
|
||
|
||
"Emulated Drive letter"
|
||
The driveletter inside dosbox (eg. C).
|
||
|
||
"Real Drive letter or Directory"
|
||
The local directory you want to have inside dosbox.
|
||
(Under Win32 usually the same as "Emulated Drive letter".
|
||
For Example: mount c c:\ )
|
||
|
||
-t type
|
||
Type of the mounted directory. Supported are: dir (standard),
|
||
floppy, cdrom.
|
||
|
||
-size drivesize
|
||
Sets the size of the drive.
|
||
|
||
-freesize sizemb
|
||
Sets the amount of free space available on a drive in MB's. This
|
||
is a more simple version of -size.
|
||
|
||
-label drivelabel
|
||
Sets the name of the drive to "drivelabel". Needed on some
|
||
systems if the cd label isn't read correctly. Useful when a
|
||
program can't find its cdrom.
|
||
|
||
-aspi
|
||
Forces to use the aspi layer. Only valid if mounting a cdrom under
|
||
Windows systems with an ASPI-Layer.
|
||
|
||
-ioctl
|
||
Forces to use ioctl commands. Only valid if mounting a cdrom under
|
||
a Windows OS which support them (Win2000/XP/NT).
|
||
|
||
-usecd number
|
||
Forces to use SDL cdrom support for drive number.
|
||
Number can be found by -cd. Valid on all systems.
|
||
|
||
-cd
|
||
Displays all detected cdrom drives and their numbers. Use with -usecd.
|
||
|
||
Note: It's possible to mount a local directory as cdrom drive.
|
||
Hardware support is then missing.
|
||
|
||
Basically, MOUNT allows you to connect real hardware to DOSBox's "emulated"
|
||
PC. So MOUNT C C:\ tells DOSBox to use your real C: drive as drive C: in
|
||
DOSBox. It also allows you to change the drive's letter identification for
|
||
programs that demand specific drive letters.
|
||
|
||
For example: Touche: Adventures of The Fifth Musketeer must be run on your C:
|
||
drive. Using DOSBox and its mount command, you can trick into thinking it
|
||
is on C drive while placing it where you want it. For example, if the game
|
||
were in D:\TOUCHE, you can use the command MOUNT C D:\ would allow you to
|
||
run Touche from the D drive.
|
||
|
||
|
||
General MOUNT Examples:
|
||
1. To mount c:\floppy as a floppy :
|
||
mount a c:\floppy -t floppy
|
||
2. To mount system cdrom drive E as cdrom drive D in DOSBox:
|
||
mount d e:\ -t cdrom
|
||
3. To mount system cdrom drive at mountpoint /media/cdrom as cdrom drive D
|
||
in dosbox:
|
||
mount d /media/cdrom -t cdrom -usecd 0
|
||
4. To mount a drive with 870 mb free diskspace (simple version):
|
||
mount c d:\ -freesize 870
|
||
5. To mount a drive with 870 mb free diskspace (experts only, full control):
|
||
mount c d:\ -size 4025,127,16513,1700
|
||
6. To mount /home/dos/dosgames as drive C in DOSBox:
|
||
mount c /home/dos/dosgames
|
||
|
||
MEM
|
||
Program to display the amount of free memory.
|
||
|
||
CONFIG [-writeconf] [-writelang] localfile
|
||
Write the current configuration or language settings to file.
|
||
"localfile" is located on the local drive !!!
|
||
|
||
Example:
|
||
To create a configfile in your current directory:
|
||
config -writeconf dosbox.conf
|
||
|
||
|
||
LOADFIX [-size] [program] [program-parameters]
|
||
LOADFIX -f
|
||
Program to "eat up" memory. Useful for old programs which don't expect much
|
||
memory to be free.
|
||
|
||
-size
|
||
number of kb to "eat up", default = 64kb
|
||
|
||
-f
|
||
frees all previously allocated memory
|
||
|
||
|
||
Examples:
|
||
1. To start mm2.exe and allocate 64kb memory :
|
||
loadfix mm2
|
||
2. To start mm2.exe and allocate 32kb memory :
|
||
loadfix -32 mm2
|
||
3. To free previous allocated memory :
|
||
loadfix -f
|
||
|
||
|
||
RESCAN
|
||
Make DOSBox reread the directory structure. Useful if you changed something
|
||
on a mounted drive outside of DOSBox.
|
||
|
||
|
||
MIXER
|
||
Makes DOSBox display its current volume settings.
|
||
You can change this way:
|
||
|
||
mixer channel left:right [/NOSHOW]
|
||
|
||
channel
|
||
Can be one of the following: MASTER, DISNEY, SPKR, GUS, SB, FM.
|
||
|
||
left:right
|
||
The volume levels in percentages. If you put a D in front it will be
|
||
in deciBell (example mixer gus d-10).
|
||
|
||
/NOSHOW
|
||
Prevents DOSBox from showing the result if you set one
|
||
of the volume levels.
|
||
|
||
|
||
IMGMOUNT
|
||
A utility to mount disk images and CD-ROM images in DOSBox.
|
||
|
||
IMGMOUNT DRIVE [imagefile] -t [image_type] -fs [image_format]
|
||
-size [sectorsbytesize, sectorsperhead, heads, cylinders]
|
||
|
||
imagefile
|
||
location of the image files to mount in DOSBox. Path is relative to
|
||
a mount point already inside DOSBox. CD-ROM images can be mounted
|
||
directly as well (path on the host).
|
||
|
||
-t
|
||
The following are valid image types:
|
||
floppy: Specifies a floppy image or images. DOSBox will automatically
|
||
identify the disk geometry ( 360K, 1.2MB, 720K, 1.44MB, etc).
|
||
iso: Specifies a CD-ROM iso image. The geometry is automatic and
|
||
set for this size. This can be an iso or a cue/bin.
|
||
hdd: Specifies a harddrive image. The proper CHS geometry
|
||
must be set for this to work.
|
||
|
||
-fs
|
||
The following are valid file system formats:
|
||
iso: Specifies the ISO 9660 CD-ROM format.
|
||
fat: Specifies the image uses the FAT file system. DOSBox will attempt
|
||
to mount this image as a drive in DOSBox and make the files
|
||
available from inside DOSBox.
|
||
none: DOSBox will make no attempt to read the file system on the disk.
|
||
This is useful if one needs to format it or one wants to boot
|
||
off of the disk using the BOOT command. When using the "none"
|
||
filesystem, one must specify the drive number (2 or 3,
|
||
where 2 = master, 3 = slave) rather than a drive letter.
|
||
For example, to mount a 70MB image as the slave drive device,
|
||
one would type:
|
||
"imgmount 3 d:\test.img -size 512,63,16,142 -fs none"
|
||
(without the quotes) Compare this with a mount to read the
|
||
drive in DOSBox, which would read as:
|
||
"imgmount e: d:\test.img -size 512,63,16,142"
|
||
|
||
-size
|
||
The Cylinders, Heads and Sectors specification of the drive.
|
||
Required to mount hard drive images.
|
||
|
||
An example of CD-ROM images:
|
||
1a. mount c /tmp
|
||
1b. imgmount d c:\myiso.iso -t iso
|
||
or (which also works):
|
||
2. imgmount d /tmp/myiso.iso -t iso
|
||
|
||
|
||
BOOT
|
||
Boot will start floppy images or hard disk images independent of the
|
||
operating system emulation offered by DOSBox. This will allow you to play
|
||
booter floppies or boot to other operating systems inside DOSBox.
|
||
|
||
BOOT [diskimg1.img diskimg2.img .. diskimgN.img] [-l driveletter]
|
||
|
||
diskimgN.img
|
||
This can be any number of floppy disk images one wants mounted after
|
||
DOSBox boots the specified drive letter.
|
||
To swap between images, one hits CTRL+F4 to swap out the current disk
|
||
and swap in the next disk in the list. Once the last disk in the list is
|
||
swapped out, the list loops back to the beginning.
|
||
|
||
[-l driveletter]
|
||
This parameter allows one to specify the drive to boot from.
|
||
The default is the A drive, the floppy drive. One can also boot off of
|
||
a hard drive image mounted as master by specifying "-l C"
|
||
without the quotes, or the drive as slave by specifying "-l D"
|
||
|
||
|
||
IPX
|
||
|
||
You need to enable IPX networking in the configuration file of DOSBox.
|
||
|
||
All of the IPX networking is managed through the internal DOSBox program
|
||
IPXNET. For help on the IPX networking from inside DOSBox, type
|
||
"IPXNET HELP" (without quotes) and the program will list out the commands
|
||
and relevant documentation.
|
||
|
||
With regard to actually setting up a network, one system needs to be
|
||
the server. To set this up, in a DOSBox session, one should type
|
||
"IPXNET STARTSERVER" (without the quotes). The server DOSBox session will
|
||
automatically add itself to the virtual IPX network. In turn, for every
|
||
other computer that should be part of the virtual IPX network,
|
||
you'll need to type "IPXNET CONNECT <computer host name or IP>".
|
||
For example, if your server is at bob.dosbox.com,
|
||
you would type "IPXNET CONNECT bob.dosbox.com" on every non-server system.
|
||
|
||
The following is an IPXNET command reference:
|
||
|
||
IPXNET CONNECT
|
||
|
||
IPXNET CONNECT opens a connection to an IPX tunneling server
|
||
running on another DOSBox session. The "address" parameter specifies
|
||
the IP address or host name of the server computer. One can also
|
||
specify the UDP port to use. By default IPXNET uses port 213, the
|
||
assigned IANA port for IPX tunneling, for its connection.
|
||
|
||
The syntax for IPXNET CONNECT is:
|
||
IPXNET CONNECT address <port>
|
||
|
||
IPXNET DISCONNECT
|
||
|
||
IPXNET DISCONNECT closes the connection to the IPX tunneling server.
|
||
|
||
The syntax for IPXNET DISCONNECT is:
|
||
IPXNET DISCONNECT
|
||
|
||
IPXNET STARTSERVER
|
||
|
||
IPXNET STARTSERVER starts and IPX tunneling server on this DOSBox
|
||
session. By default, the server will accept connections on UDP port
|
||
213, though this can be changed. Once the server is started, DOSBox
|
||
will automatically start a client connection to the IPX tunneling server.
|
||
|
||
The syntax for IPXNET STARTSERVER is:
|
||
IPXNET STARTSERVER <port>
|
||
|
||
IPXNET STOPSERVER
|
||
|
||
IPXNET STOPSERVER stops the IPX tunneling server running on this DOSBox
|
||
session. Care should be taken to ensure that all other connections have
|
||
terminated as well since stopping the server may cause lockups on other
|
||
machines still using the IPX tunneling server.
|
||
|
||
The syntax for IPXNET STOPSERVER is:
|
||
IPXNET STOPSERVER
|
||
|
||
IPXNET PING
|
||
|
||
IPXNET PING broadcasts a ping request through the IPX tunneled network.
|
||
In response, all other connected computers will respond to the ping
|
||
and report the time it took to receive and send the ping message.
|
||
|
||
The syntax for IPXNET PING is:
|
||
IPXNET PING
|
||
|
||
IPXNET STATUS
|
||
|
||
IPXNET STATUS reports the current state of this DOSBox's sessions
|
||
IPX tunneling network. For a list of the computers connected to the
|
||
network use the IPXNET PING command.
|
||
|
||
The syntax for IPXNET STATUS is:
|
||
IPXNET STATUS
|
||
|
||
For more information use the /? command line switch with the programs.

5. Special Keys:
|
||
================
|
||
|
||
ALT-ENTER Go full screen and back.
|
||
CTRL-F1 Start the keymapper.
|
||
CTRL-F4 Swap mounted disk-image (Only used with imgmount).
|
||
CTRL-F5 Save a screenshot.
|
||
CTRL-F6 Start/Stop recording sound output to a wave file.
|
||
CTRL-ALT-F7 Start/Stop recording of OPL commands.
|
||
CTRL-ALT-F8 Start/Stop the recording of raw MIDI commands.
|
||
CTRL-F7 Decrease frameskip.
|
||
CTRL-F8 Increase frameskip.
|
||
CTRL-F9 Kill dosbox.
|
||
CTRL-F10 Capture/Release the mouse.
|
||
CTRL-F11 Slow down emulation (Decrease DOSBox Cycles).
|
||
CTRL-F12 Speed up emulation (Increase DOSox Cycles).
|
||
|
||
These are the default keybindings. They can be changed in the keymapper.
|
||
|
||
NOTE: Once you increase your DOSBox cycles beyond your computer's maximum
|
||
capacity, it will produce the same effect as slowing down the emulation.
|
||
This maximum will vary from computer to computer, there is no standard.
|
||
|
||
|
||

|
||
6. Keymapper:
|
||
=============
|
||
|
||
When you start the keymapper (either with CTRL-F1 or -startmapper as a
|
||
commandline argument) you are presented with a virtual keyboard.
|
||
|
||
This virtual keyboard corresponds with the keys DOSBox will report to its
|
||
applications. If you click on a key with your mouse, you can see in the
|
||
lowerleft corner which key on your keyboard corresponds with it.
|
||
|
||
Event: EVENT
|
||
BIND: BIND
|
||
Add Del
|
||
mod1 hold Next
|
||
mod2
|
||
mod3
|
||
|
||
|
||
EVENT
|
||
The key DOSBox will report to the applications being emulated.
|
||
BIND
|
||
The key on your keyboard (as reported by SDL) which is connected to the
|
||
EVENT.
|
||
mod1,2,3
|
||
Modfiers. These are keys you need to have pressed as well, while pressing
|
||
BIND. mod1 = CTRL and mod2 = ALT. These are generally only used when you
|
||
want to change the special keys of DOSBox.
|
||
Add
|
||
Add a new BIND to this EVENT. Basicly add a key from your keyboard which
|
||
will produce the key EVENT in DOSBox.
|
||
Del
|
||
Delete the BIND to this EVENT. If an EVENT has no BINDS than it's not
|
||
possible to type this key in DOSBox.
|
||
Next
|
||
Cycle through the list of keys(BINDS) which map to this EVENT.
|
||
|
||
|
||
Example:
|
||
Q1. You want to have the X on your keyboard to type a Z in DOSBox.
|
||
A. With your mouse click on the Z on the keyboard mapper. Click "Add".
|
||
Now press the X key on your keyboard.
|
||
|
||
Q2. If you click "Next" a few times you will notice that the Z on your
|
||
keyboard also produces an Z in DOSBox.
|
||
A. Therefore select the Z again and click "Next" till you have the Z on
|
||
your keyboard. Now click "Del".
|
||
|
||
Q3. If you try it out in DOSBox you will notice that pressing X makes ZX
|
||
appear.
|
||
A. The X on your keyboard is still mapped to the X as well! Click on
|
||
the X in the keyboard mapper and search with "Next" till you find the
|
||
mapped key X. Click "Del".
|
||
|
||
|
||
If you change the default mapping you can save your changes by pressing
|
||
"Save". DOSBox will save the mapping to location specified in the configfile
|
||
(mapperfile=mapper.txt). At startup DOSBox will load your mapperfile if it's
|
||
present in the configfile.

||
7. System requirements:
|
||
=======================
|
||
|
||
Fast machine. My guess would be pentium-2 400+ to get decent emulation
|
||
of games written for an 286 machine.
|
||
For protected mode games a 1 Ghz machine is recommended and don't expect
|
||
them to run fast though!! Be sure to read the next section on how to speed
|
||
it up somewhat.
|
||
|
||
|
||
|
||
===================================
|
||
8. To run resource-demanding games:
|
||
===================================
|
||
|
||
DOSBox emulates the CPU, the sound and graphic cards, and some other
|
||
stuff, all at the same time. You can overclock DOSBox by using CTRL+F12, but
|
||
you'll be limited by the power of your actual CPU. You can see how much free
|
||
time your true CPU has by looking at the Task Manager in Windows 2000/XP and
|
||
the System Monitor in Windows 95/98/ME. Once 100% of your real CPU time is
|
||
used there is no further way to speed up DOSBox unless you reduce the load
|
||
generated by the non-CPU parts of DOSBox.
|
||
|
||
So:
|
||
|
||
Close every program but DOSBox
|
||
|
||
Overclock DOSBox until 100% of your CPU is used (use the utilities above to
|
||
check)
|
||
|
||
Since VGA emulation is the most demanding part of DOSBox in terms of actual
|
||
CPU usage, we'll start here. Increase the number of frames skipped (in
|
||
increments of one) by pressing CRTL+F8. Your CPU usage should decrease.
|
||
Go back one step and repeat this until the game runs fast enough for you.
|
||
Please note that this is a trade off: you lose in fluidity of video what you
|
||
gain in speed
|
||
|
||
You can also try to disable the sound through the setup utility of the game
|
||
to further reduce load on your CPU.
|
||
|
||
|
||
|
||
===================
|
||
9. The Config File:
|
||
===================
|
||
|
||
A config file can be generated by CONFIG.COM, which can be found on the
|
||
internal dosbox Z: drive when you start up dosbox. Look in the internal
|
||
programs section of the readme for usage of CONFIG.COM.
|
||
You can edit the generated configfile to customize DOSBox.
|
||
|
||
The file is divided into several sections (the names have [] around it).
|
||
Some sections have options which you can set.
|
||
# and % indicate comment-lines.
|
||
The generated configfile contains the current settings. You can alter them and
|
||
start DOSBox with the -conf switch to load the file and use these settings.
|
||
|
||
If no configfile is specified with the -conf switch, DOSBox will look in the
|
||
current directory for dosbox.conf. Then it will look for ~/.dosboxrc (Linux),
|
||
~\dosbox.conf (Win32) or "~/Library/Preferences/DOSBox Preferences" (MACOSX).
|
||
|
||
|
||
|
||
======================
|
||
10. The Language File:
|
||
======================
|
||
|
||
A language file can be generated by CONFIG.COM.
|
||
Read it and you will hopefully understand how to change it.
|
||
Start DOSBox with the -lang switch to use your new language file
|
||
or you can setup the filename in the config file in the [dosbox] section.
|
||
There's a language= entry that can be changed with the filename.
|
||
|
||
|
||
|
||
========================================
|
||
11. Building your own version of DOSBox:
|
||
========================================
|
||
|
||
Download the source.
|
||
Check the INSTALL in the source distribution.
|
||
