GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Things needed for compilation.
SDL
The Simple DirectMedia Library available at http://www.libsdl.org
The dll distributed with the windows version of DOSBox is slightly
modified. You can find the changes in the sourcepackage of DOSBox
(src/platform/sdl-win32.diff). If you want the patched sourcetree
send us an email. (see README)
Licensed under LGPL
Curses (optional)
If you want to enable the debugger you need a curses library.
ncurses should be installed on just about every unix distro.
For win32 get pdcurses at http://pdcurses.sourceforge.net
License: Open source
Libpng (optional)
Needed for the screenshots.
For win32 get libpng from http://gnuwin32.sourceforge.net/packages.html
See http://www.libpng.org/pub/png/ for more details.
License: Open Source
Zlib (optional)
Needed by libpng.
For win32 get libz (rename to zlib) from http://gnuwin32.sourceforge.net/packages.html
See http://www.zlib.net for more details.
License: Open Source
SDL_Net (optional)
For modem/ipx support. Get it from http://www.libsdl.org/projects/SDL_net/
Licensed under LGPL
SDL_Sound
For compressed audio on diskimages. (optional)
This is for cue/bin cdrom images with compressed (mp3/ogg) audio tracks.
Get it from http://icculus.org/SDL_sound
Licenced under LGPL
ALSA_Headers
(optional)
for Alsa support under linux. Part of the linux kernel sources
Licensed under LGPL
If you want compile from the CVS under a unix system, you'll also need
automake (>=1.6), autoconf(>=2.50). Should be available at http://www.gnu.org
For building on unix systems.
If you are building from the cvs run ./autogen.sh first before doing the following.
1. ./configure
2. make
In step 1 you could add the following switches:
--enable-debug
enables the internal debugger. --enable-debug=heavy enables even more
debug options. Dosbox should then be run from a xterm and when the sdl-
window is active press alt-pause to enter the debugger.
--enable-core-inline
enables some memory increasing inlines. This greatly increases
compiletime for maybe a increase in speed.
--disable-fpu
disables the emulated fpu. Although the fpu emulation code isn't
finished and isn't entirely accurate it's advised to leave it on.
--disable-fpu-x86
disables the assembly fpu core. Although relatively new the x86 fpu
core has more accuracy then the regular fpu core.
--disable-dynamic-x86
disables the dynamic x86 specific cpu core. Although it might be
be a bit unstable, it can greatly improve the speed of dosbox on x86
hosts.
Please note that this option on x86 will result in a different
dynamic/recompiling cpu core being compiled then the default.
For more information see the option --disable-dynrec
--disable-dynrec
disables the recompiling cpu core. Currently x86 and x86_64 only.
You can activate this core on x86 by disabling the dynamic-x86 core.
--disable-dynamic-core
disables all dynamic cores. (same effect as
--disable-dynamic-x86 --disable-dynrec)
--disable-unaligned-memory
disables unaligned memory access.
Check the src subdir for the binary.
NOTE: If capslock and numlock appear to be broken. open
src/ints/bios_keyboard.cpp and go to line 30 and read there how to fix it.
Build instructions for VC++6
Don't use VC++ 6:it creates faulty code in core_normal.cpp
First of all if you are running a non-x86 machine this will not work,
code only works for big-endian machines for now :)

2. Check settings.h for some setup options.
3. make
Check the src subdir for the binary and dosbox.lang file.
These 2 files should be in the same dir if you want to run dosbox.
Compiling on FreeBSD might be a problem since SDL has no joystick support there.
To get around this edit sdlmain.cpp to enable some #define.
Let's hope someday the sdl people will just report 0 joysticks in freebsd or get it working some other way :)
Build instructions for VC++6
Open the workspace in the visualc subdir and build from there.
Copy the src/dosbox.lang file to the same dir as your executable.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#

## (We might end up doing this anyway to support other compilers.)

## -MM, not -M (despite what the docs say).

## dummy dependencies for each header file. Too bad gcc doesn't do

Some notes about porting DOSBox to systems with certain restrictions,
like handheld devices.
If memory is a constraint:
- in paging.h out-comment the USE_FULL_TLB define to enable special
TLB linking code that uses less memory
drawback: none (the code is not heavily tested though)
gain: reduces memory requirements about ~15mb
- in render.h lower the scaler integration:
#define RENDER_USE_ADVANCED_SCALERS 1
or
#define RENDER_USE_ADVANCED_SCALERS 0
drawback: complex scalers and the scaler cache are disabled,
be sure to test if this affects speed!
with define RENDER_USE_ADVANCED_SCALERS==0 most simple
scalers are disabled as well, some graphics modes won't
work due to reduced cache sizes
gain: ~2mb with RENDER_USE_ADVANCED_SCALERS==1
~5mb with RENDER_USE_ADVANCED_SCALERS==0
- in dos_system.h reduce the drive cache entries:
#define MAX_OPENDIRS 256
drawback: some apps might not work with large directory trees
gain: ~1mb per mounted drive
- remove the GUS emulation (gus.cpp, especially GUSRam[1024*1024] )
drawback: no gravis ultrasound
gain: reduces memory requirements about 1mb
- reduce the size of the emulated graphics memory:
see the memory sizing in SVGA_Setup_*, especially the defaults
in vga_s3.cpp's SVGA_Setup_S3Trio
drawback: some graphics modes won't work then
gain: reduces memory requirements
TODO: fully check this, introduce hard limits
If speed is a constraint:
- see if the simple core is faster, possibly remove the normal core
set the simple core as default
drawback: one game is known to not work with the simple core;
the simple core does only work for games which don't use paging
(when paging is requested the normal core is used automatically)
gain: the simple core should be somewhat faster
TODO: add possibility to easily remove the normal core, use fullcore fallback
- raise the default frameskip value
drawback: minor graphics smoothness loss for some games (video playback)
gain: reduces graphics load

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.
Q: The colours are wrong and I'm using 64 bit windows
A: Look here: http://vogons.zetafleet.com/viewtopic.php?t=12133

the specified scaler even if it might not fit.
.TP
.BI \-c " command"
.RI "Runs the specified " command " before running "
.BR file .
.RI "Multiple commands can be specified. Each " command " should start with "
.BR \-c " though. A command can be:"
an Internal Program, a DOS command or an executable on a mounted drive.
.TP
.BI \-conf " configfile
.RB "Start " dosbox " with the options specified in "

systems if the cd label isn't read correctly. Useful when a
program can't find its cdrom. If you don't specify a label and no
.RB "lowlevel support is selected (" "\-usecd #" " and/or " "\-ioctl/aspi" "):"
.RS
.LP
For win32: label is extracted from "Real Drive".

.RI "internal commands " MOUNT ", " IMGMOUNT " and " BOOT " won\'t work."
It\'s not possible
either to create a new configfile or languagefile in this mode.
(Warning you can only undo this mode by restarting
.BR dosbox .)
.LP
The configuration file controls various settings of
.BR dosbox ": The amount of emulated memory,"
the emulated soundcards and many
.RI "more things. It futher allows acces to " AUTOEXEC.BAT .
.LP

.RE
.TP
.B IPX
.LP
.RB "You need to enable IPX networking in the configuration file of " dosbox .

.SH FILES
Configuration and language files use a format similar to Windows .ini files.
First ~/.dosboxrc (if present) will be loaded. If no
configfile is specified at the commandline, a file named
.BR dosbox.conf " (if present in the current directory) will be"
loaded automatically afterwards. If a configfile is specified at the commandline
that one will be used instead.
.SH "SPECIAL KEYS"
.TP 12m
.IP ALT\-ENTER
Go full screen and back.
.IP ALT\-PAUSE
Pause emulation.
.IP CTRL\-F1
Start the keymapper.
.IP CTRL\-ALT\-F5
Start/Stop creating a movie of the screen.
.IP CTRL\-F4
Swap mounted disk-image (Only used with imgmount). Update directory cache
for all drives!
.IP CTRL\-F5
Save a screenshot.(png)
.IP CTRL\-F6
Start/Stop recording sound output to a wave file.
.IP CTRL\-ALT\-F7
Start/Stop recording of OPL commands.
.IP CTRL\-ALT\-F8
Start/Stop the recording of raw MIDI commands.
.IP CTRL\-F7
Decrease frameskip.
.IP CTRL\-F8
Increase frameskip.
.IP CTRL\-F9
Kill dosbox.
.IP CTRL\-F10
Capture/Release the mouse.
.IP CTRL\-F11
Slow down emulation (Increase dosbox Cycles).
.IP CTRL\-F12
Speed up emulation (Decrease dosbox Cycles).
.IP ALT\-F12
Unlock speed (turbo button).
.PP
These are the default keybindings. They can be changed in the keymapper.
.PP
Saved/recorded files can be found in current_directory/capture
(can be changed in the configfile).
.RB "The directory has to exist prior to starting " dosbox " else nothing"
gets saved/recorded !
.PP
.BR "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.
.SH "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.
.SS "To run resource\-demanding games"
.BR dosbox " emulates the CPU, the sound and graphic cards, and some other"
.RB " 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 various utils (top). Once 100% of your real CPU time is
.RB "used there is no further way to speed up " dosbox " unless you reduce the load"
.RB "generated by the non\-CPU parts of " dosbox .
.PP
So:
.PP
.RB "Close every program but " dosbox .
.PP
.RB "Overclock " dosbox " until 100% of your CPU is used.(CTRL\-F12)"
.PP
.RB "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 CTRL\-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.
.SH NOTES
.RB "While we hope that, one day, " dosbox " will run virtually all programs ever made for the PC..."
.RB "we are not there yet. At present, " dosbox " run on a 1.7 Gigahertz PC is roughly the equivalent of a 25MHz 386 PC."
While 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
.RB "require a much faster processor for you to run it properly in " dosbox .
.SH BUGS
Not all DOS programs work properly.
.BR dosbox " will exit without warning if an error occurred."
