In the early 1970's, video arcade games gained commercial success for the
first time. The American public was introduced to Pong, Tank, and other
interactive video games which populated amusement parks, bars, and arcades.
The games were successful enough to create interest for home versions, so in
1975 Atari released Home Pong and it was a smash hit. Other companies such as
Magnavox and Coleco followed suit and released their own dedicated console
games. Then in 1976, Fairchild Camera and Instrument introduced the Channel F
system, the first cartridge based home video game system. The industry
recognized that cartridge systems were the future of video gaming, and began
development in that direction. In January 1977, RCA released the Studio II,
another cartridge based system, although it only projected in black and white
and seemed to be focused on educational titles. Then, in October 1977, Atari
released the Atari VCS (Video Computer System) with an initial offering of nine
games. This system, later renamed the Atari 2600, took the industry by storm
and dominated the marketplace for years to come.
< / p >
< p > < a > < img src = "graphics/chucky_cheese.png" ALIGN = LEFT > < / a >
Because of oversupply, the Christmas season of 1977 was very rough on the
video game industry, and the Atari 2600 was the only system that managed to
emerge unscathed. Atari enjoyed strong sales in 1978 and a fantastic holiday
season, as Atari released more games such as Outlaw, Spacewar, and Breakout.
Internally however, Atari was at odds. Nolan Bushnell, the inventor of pong and
founder of Atari, wound up leaving the company and purchased Pizza Time Theater,
which later became the successful Chuck E. Cheese! In 1979 Atari continued
their trend and released 12 more games which met with continued success.
However, Atari was now facing some stiffer competition from the Mattel
Intellivision and the Magnavox Odyssey2.
< / p >
< p > < a > < img src = "graphics/space_invaders.png" ALIGN = RIGHT > < / a >
Atari needed a mega-hit in 1980 in order to squash the competition, and they
found it in the home version of a game from Japan called Space Invaders. It was
so popular that people were buying the Atari 2600 just so they could play Space
Invaders at home. Following that, Atari released Adventure, which was the first
video game to contain an Easter Egg - placing an object in a certain area
revealed the programmer's name, Warren Robinett. 1980 was important for another
reason - the creation of the first ever third party software producer, Activision.
The company was formed by four Atari employees who were unsatisfied with the
working conditions at the company. They released four games initially: Dragster,
Fishing Derby, Checkers and Boxing. The games were very well received by the
public, and revealed that the Atari 2600 was capable of better games than
Atari themselves had been producing. Atari tried to prevent Activision from
selling games, but they failed and Activision grossed $70 million that year.
< / p >
< p >
By 1981, the video game industry was basically a horse race between the 2600
and the Intellivision. While the Intellivision was technologically superior in
some respects, the 2600 continued to lead in sales. Atari released the home
version of Asteroids, which was a huge success. Inspired by the success of
Activision, another software development group called Imagic was formed. They
would not release any games until 1982 however. Another company, Games by Apollo,
was formed in Texas and released several games that year.
< / p >
< p >
Coleco entered the market in 1982 with the release of the graphically
superior Colecovision. To combat this new system, Atari produced the 5200,
a technologically comparable system. The 2600 dropped $100 in price in order
to remain competitive. Then a company called Arcadia released a peripheral
called the Supercharger which played games in an audio cassette medium. This
allowed for multiple loads and expanded the 2600's capabilities.
< p > < a > < img src = "graphics/pacman.png" ALIGN = LEFT > < / a >
Atari released Pac-Man and E.T. that year, two incredibly hyped games which
were critical flops.
Although Pac-Man sold many copies, it was considered to be a poor
translation of the arcade hit. However, there were many fantastic games
produced for the 2600 during this period, and it was still selling strong.
< / p >
< p >
Ever since the inception of Activision, Atari had been fighting to keep third
parties from producing cartridges which they felt were stealing profits from
them. Finally the issue was settled when Atari agreed to allow third party
manufacturing in exchange for a royalty. Suddenly software companies began
popping up all over, and 1982 saw releases from companies like Venturevision,
Spectravision, Telesys, CBS, 20th Century Fox, US Games, M Network, Tigervision,
Data Age, Imagic and Coleco. There was even a company that released a line of
2016-12-31 20:49:29 +00:00
X-Rated games for the 2600 called Mystique. The year was financially successful
2010-08-02 11:16:42 +00:00
for Atari, however there seemed to be a glut of software. Although there were
many quality titles still produced, there was an increasing number of rushed
games as manufacturers attempted to cash in on the craze.
< / p >
< p >
More companies jumped on the band wagon in 1983. Zimag, Ultravision, Amiga,
and others were also producing games and peripherals. It seemed as if there was
just too much product to meet the demand, and as it turned out there was. By
the end of the year, companies began folding. US Games, Data Age, Games by
Apollo, Telesys and others all closed their doors from poor sales. A video
game crash was occurring, and all companies were taking it on the chin.
< / p >
< p >
1984 was a much more subdued year for the Atari 2600, and the price of the
system had now dropped to $40-$50. Many were saying that the video game
industry was dead. However, Atari surprised everyone by announcing the release
of the 7800, and also promising more 2600 games with improved graphics and
sound. Unfortunately, neither of these things happened in 1984 because Atari
sold their home video game division to Jack Tramiel who believed that home
computers would replace video game systems. No further mention of the 2600 or
7800 was made that year, and it appeared that they might be dead.
< / p >
< p >
1985 was another very quiet year for Atari and video games in general, and only
a few games were released for the 2600. Activision produced Cosmic Commuter and
Ghostbusters, but with little fanfare or marketing, these games did not sell
well. However, because of the huge game library and cheap price, Atari still
sold over a million 2600 consoles in 1985.
< / p >
< p >
There were very few plans for home video game systems by any company in 1986,
since the market appeared to be dead. Then, to most people's surprise, Nintendo
brought the NES to America and it was a smash hit, proving that video games
still had a place in the US. Atari decided that maybe it would be a good idea
to release the 7800 units it had in storage, and produce some more 2600 games.
The 7800 was released with only 3 games initially available, although it was
compatible with the 2600 library. They also redesigned the 2600 as the 2600 Jr.,
a machine with the same abilities, but a new look and marketing campaign. It
was sold for less than $50.
< / p >
< p > < a > < img src = "graphics/jr_pacman.png" ALIGN = RIGHT > < / a >
Video games were once again selling phenomenally in 1987. Atari released
several new titles, including Jr. Pac-Man, and also licensed a number of games
from other companies such as Donkey Kong and Q*Bert. These new titles sold for
$10-$15. Interestingly, a number of titles began appearing again from third
part companies such as Epyx, Froggo, and Exus. It seemed that the 2600 was not
dead yet!
< p > < a > < img src = "graphics/secret_quest.png" ALIGN = LEFT > < / a >
In 1988, Atari rehired Nolan Bushnell and announced a number of new
titles, including Secret Quest, a game written by Mr. Bushnell himself. Atari
continued to manufacture these games even until 1989. However, it was apparent
that the 2600, after its introduction over a decade ago, was finally at the end
of its run. Although it was still produced and marketed outside of the US, the
Atari 2600 finished its run in America. No other console has had such a long
history or sold as many systems in the U.S.
< / p >
< p >
Today, the 2600 still has a large number of fans who remember the countless
games played over the years, and the years to come. There are even games being
produced by hobbyists, some of them quite professionally, being released on
newly burnt cartridges with labels and manuals. And the recent trend in
retrogaming has brought many more video game fans to rediscover the 2600, and
it continues to live on 22 years after its release!

download and install the appropriate binary version. Compiling from source is only
2010-08-02 11:16:42 +00:00
recommended for developers, or if the binary version doesn't work for some reason.

< p > Most games for the Atari 2600 came on cartridges. A cartridge usually
2010-08-02 11:16:42 +00:00
consists of a single Read Only Memory (ROM) chip which contains the data and
2017-12-02 10:34:58 +00:00
code for the game. Plugging a cartridge into the Atari 2600 allows the 2600's
2010-08-02 11:16:42 +00:00
microprocessor to access the program stored on the cartridge.< / p >
2002-04-22 01:45:08 +00:00
2010-08-02 11:16:42 +00:00
< p > In a similar way you must "plug" a copy of a cartridge into Stella when you
2017-12-08 13:28:09 +00:00
want to play it. Having a ROM image/BIN file of the cartridge allows you to
2017-12-02 10:34:58 +00:00
do this. A ROM image is a file, which contains the actual data and code read
from the cartridge. There are several ways to obtain a ROM image of a

cartridge:< / p >

< p > Supercharger games were not stored on cartridges instead they were stored
on cassette tapes. The Supercharger, which plugged into the Atari 2600's
cartridge slot, loaded games into its 6K of Random Access Memory (RAM) using a
2017-12-02 10:34:58 +00:00
standard audio cassette player. The Supercharger also supported multi-loading,
2010-08-02 11:16:42 +00:00
which allowed games to be broken into several segments and loaded at different
2017-12-02 10:34:58 +00:00
times. This was useful for large games which had distinct parts such as role
2010-08-02 11:16:42 +00:00
playing games.< / p >
2002-04-22 01:45:08 +00:00
2010-08-02 11:16:42 +00:00
< p > Most of the available Supercharger ROM images are stored in 8448 bytes files.
However, ROM images of multi-load games are sometimes stored in a set of 8448
byte files. The names of these files have a two character sequence number in
2017-12-02 10:34:58 +00:00
them which indicates what load they are. The sequence starts with zero, skips
2010-08-02 11:16:42 +00:00
a few numbers and then increments by one.< / p >
2002-04-22 01:45:08 +00:00
2010-08-02 11:16:42 +00:00
< p > Stella supports multi-load games, however, the set of ROM images must be
2017-12-02 10:34:58 +00:00
combined into a single ROM image file. For example to create a multi-load ROM
2010-08-02 11:16:42 +00:00
image file for Survival Island you would do the following under Unix:
2002-04-22 01:45:08 +00:00
2010-08-02 11:16:42 +00:00
< pre > % cat survivl0.bin survivl6.bin survivl7.bin > survivl.bin< / pre >
2016-12-31 20:49:29 +00:00
2010-08-02 11:16:42 +00:00
or to create it under DOS you would:
2002-04-22 01:45:08 +00:00
2010-08-02 11:16:42 +00:00
< pre > % copy /b survivl0.bin+survivl6.bin+survivl7.bin survivl.bin< / pre >
2002-04-22 01:45:08 +00:00
2010-08-02 11:16:42 +00:00
< p > Once you have the multi-load ROM image file, survivl.bin in this case, you
can play the game using it.< / p >

For the last two compressed formats (GZIP and ZIP, respectively), Stella will
automatically decompress the archive, and use the first ROM image it finds in
it (ie, the first one ending in a valid extension).< / p >

2017-12-02 10:34:58 +00:00
by default, all Stella-related files are stored. Double-clicking an item will
enter that directory. Click 'Choose' to select the location, or 'Cancel' to exit
the browser. Note that if you don't select a ROM directory now, you will be prompted

These settings are optional, and can be left at the defaults if you won't be using
snapshots in the ROM launcher.< / p >
2010-08-02 11:16:42 +00:00
< p > Once you've correctly set the default ROM directory, you can start emulation by
2010-07-06 15:08:35 +00:00
selecting a ROM and pressing 'Enter' or clicking 'Select', or double-clicking a ROM.
2017-12-02 10:34:58 +00:00
Note that some games require you to 'Reset' the console before you start playing. In this
2010-08-02 11:16:42 +00:00
case, you need to hit the virtual reset switch, which by default is the F2 key.
Also, some games may require that you press the joystick fire button to begin,
2017-12-02 10:34:58 +00:00
which by default is the Left Control or Space key(s). If a game uses a
2010-08-02 11:16:42 +00:00
more complex controller, see

< p > While playing a game, normally one would use the keyboard shortcuts for controlling the
2010-08-02 11:16:42 +00:00
'virtual' switches in Stella (ie, the commands associated with the
function keys as described in
2010-07-20 16:41:35 +00:00
< b > Getting Started - < a href = "#Keyboard" > Keyboard Layout< / a > < / b > ).
2017-12-02 10:34:58 +00:00
However, another alternative is available. Pressing the '\' key toggles
2010-08-02 11:16:42 +00:00
a command menu dialog as follows:< / p >
< p > < img src = "graphics/commandmenu.png" > < / p >
< p > This dialog contains a set of buttons that represent the same functionality
2017-12-02 10:34:58 +00:00
as the function keys. You may find this useful if you cannot remember all
2010-08-02 11:16:42 +00:00
the function key events, or you wish to use Stella without a keyboard (ie,
in a standalone gaming system).< / p >

< p > The default options in Stella are meant to cater to as many situations as
2017-12-02 10:34:58 +00:00
possible. As such, you may never need to change many of its options. However,
2010-07-06 15:08:35 +00:00
Stella is very configurable, and if you want to change its behaviour in some way,
2017-12-02 10:34:58 +00:00
there's likely a configuration option to do so. The remainder of this (lengthy)
2010-07-06 15:08:35 +00:00
section details every configurable option.< / p >

2017-07-25 17:02:02 +00:00
Higher blend values will intensify the phosphor effect. Depending on your
display and personal preferences, the optimal default for you may vary.
Slow LCDs (especially for office use) may only need a low blend of
around 30, while fast switching gamer LCDs may need about 70 to look
similar to a CRT.

Added logging capability and viewer. This is useful for those platforms that
don't normally use the commandline (mostly Windows, but in some cases OSX as
well). The 'showinfo' commandline argument has been renamed 'loglevel', but
it has the same purpose. A new option 'logtoconsole' has been added, which
determines whether log output should also be directed to the commandline/
console (previously, it was always printed to the console). All these items
are now accessible from Options -> System Logs.
For anyone reading this (and that cares), now I can finally move on to the
OpenGL rewrite. The plan is that the new code will use OpenGL ES, which
is a subset of OpenGL 1.5. The main advantages are that you won't need
an advanced OpenGL card, and OpenGL ES is supported on most new 'smaller'
systems (iPhone, Android, etc), making ports much easier.

< p > Almost every event in Stella can be remapped to another key on the keyboard or
to buttons on up to eight joysticks/gamepads (see < b > Getting Started -
< a href = "#Keyboard" > Keyboard Layout< / a > < / b > for those events which can/cannot be
remapped).< / p >
< p > Note that there are currently two separate event modes in Stella; emulation
2017-12-02 10:34:58 +00:00
mode and user-interface (UI) mode. Each mode has separate mappings, so (for example)
2010-08-02 11:16:42 +00:00
while in emulation mode, the left arrow could mean 'joystick 0 left', while in UI
2017-12-02 10:34:58 +00:00
mode it could mean 'move cursor left'. Emulation mode occurs whenever you're
actually playing a game. UI mode occurs whenever a user interface is present
(ROM launcher, debugger, settings menu, etc.). Because of these different modes,
2010-08-02 11:16:42 +00:00
there are two separate mapping areas.
< p > To remap an event:
< ol >
2017-12-08 13:28:09 +00:00
< li > Enter < b > Options Menu< / b > and click the < b > Input Settings< / b > button.< / li >
2010-08-02 11:16:42 +00:00
< li > If you wish to remap emulation events, click the 'Emul. Events' tab.
Otherwise, click the 'UI Events' tab for user interface events.< / li >
< li > Select event you want to remap and click the 'Map' button.< / li >

2017-12-02 10:34:58 +00:00
selected ROM in the ROM launcher. Support is automatic, as long as your
snapshot directory contains snapshots in the appropriate format. An
2010-08-02 11:16:42 +00:00
archive of updated snapshots will be available on the Stella webpage.
This archive may be updated periodically as new ROMs are found, and also
2017-12-02 10:34:58 +00:00
for each new release of Stella. Note that the snapshots can be any size
2010-08-02 11:16:42 +00:00

least 640x480. If the launcher isn't large enough, the functionality
2010-08-02 11:16:42 +00:00
will be disabled.< / li >
< li > To view snapshots in 2x mode, the ROM launcher window must be sized at
2017-12-02 10:34:58 +00:00
least 1000x760. If the launcher isn't large enough, an attempt will
2010-08-02 11:16:42 +00:00

(subject to the restrictions from the filtering option, explained below).
Typing characters here will show only those files that match that
2017-12-02 10:34:58 +00:00
pattern. For example, typing 'Activision' will show only files that
contain the word 'Activision' in their name. This is very useful for
quickly finding a group of related ROMs. Note that the search is not
2010-08-02 11:16:42 +00:00
case sensitive, so you don't need to worry about capital or lower-case
letters.< / p >

< p > Stella supports a real AtariVox device for the speech/SpeakJet portion
2017-12-02 10:34:58 +00:00
of the controller. You will need a real AtariVox device
2010-08-02 11:16:42 +00:00
as well as some means of connecting it to your computer (some sort of
2017-12-02 10:34:58 +00:00
serial port/USB adaptor). There should be drivers for your serial convertor,
2010-08-02 11:16:42 +00:00
which allow your particular operating system to 'see' the device (configuring
2017-12-02 10:34:58 +00:00
this is outside the scope of this document). Once your operating system
2010-08-02 11:16:42 +00:00
properly detects the AtariVox, you will need to tell Stella which serial
2017-12-02 10:34:58 +00:00
port it is connected to. This is done by using the '-avoxport' commandline
2010-08-21 23:08:44 +00:00
argument, or by setting it in the UI under the 'Devices & Ports' tab in

< p > Support for the EEPROM portion of the AtariVox and SaveKey is currently
2017-12-02 10:34:58 +00:00
emulated. That is, a file will be created on your computer simulating the
2010-08-02 11:16:42 +00:00
EEPROM; the actual EEPROM hardware itself will not be accessed or modified.
This is very useful in the testing stages of creating a new game, since
writing to a real EEPROM many times will eventually wear it out.< / p >

going back further in time. To reach the horizon, save states
2017-12-13 18:15:09 +00:00
will be compressed (*). This means that more and more intermediate
2017-12-06 16:44:14 +00:00
states will be removed and the interval between save states
2018-01-29 15:58:26 +00:00
becomes larger the further they are back in time.< br >
2017-12-13 18:15:09 +00:00
(*) Compresion only works if 'Uncompressed size' is smaller than
'Buffer size'.

< p > Stella will remember when you change a setting either at the command line
or while the emulation is running, and use the settings the next time
2017-12-02 10:34:58 +00:00
you start the emulator. The settings are saved in a text file which can
be edited outside of Stella. This file can contain your default options,
and eliminates the need to specify them on the command line. Any
2010-08-02 11:16:42 +00:00
options specified on the command line will override those in the settings file.< / p >
2017-12-02 10:34:58 +00:00
< p > The syntax for the settings file is very straightforward. Any line starting with
a ';' character is considered a comment and is ignored. Other lines must be of
2010-08-02 11:16:42 +00:00
the form: < b > command = value< / b > , where < i > command< / i > is the same as that
specified on the command line (without the '-' character), and < i > value< / i >
is dependent on the command.< / p >
< p > For example, the following table illustrates how command line and settings entries
are similar:< / p >
< table BORDER = 2 >

Added logging capability and viewer. This is useful for those platforms that
don't normally use the commandline (mostly Windows, but in some cases OSX as
well). The 'showinfo' commandline argument has been renamed 'loglevel', but
it has the same purpose. A new option 'logtoconsole' has been added, which
determines whether log output should also be directed to the commandline/
console (previously, it was always printed to the console). All these items
are now accessible from Options -> System Logs.
For anyone reading this (and that cares), now I can finally move on to the
OpenGL rewrite. The plan is that the new code will use OpenGL ES, which
is a subset of OpenGL 1.5. The main advantages are that you won't need
an advanced OpenGL card, and OpenGL ES is supported on most new 'smaller'
systems (iPhone, Android, etc), making ports much easier.

along with a list of codes for various games. Cheetah codes
2010-08-02 11:16:42 +00:00
don't support bankswitched ROMs, so they only work for 2K or 4K ROMs.
Format as follows:

6-digit (cheetah) code: aaaddc

< p > Stella maintains a log of its operations when the program first starts up, and
2017-12-02 10:34:58 +00:00
while it is running. In older releases, this information was only viewable from the
commandline. However, the current release allows
you to see this information from within the UI. This can be selected from the main
Options menu, where it is labelled "System Logs". Clicking on the button will show

is also shown on the commandline from which Stella was launched (if it was launched
2017-12-02 10:34:58 +00:00
in that fashion). Finally, the current contents of the system log can be saved to your

< p > An Atari 2600 palette consists of 128 colours, which are different
for the three major television standards (NTSC, PAL, SECAM).
Stella supports two built-in palettes and one user-defined palette for each format.
These are set using the '-palette' option, and are described as follows:< / p >

< p > A user-defined palette has certain restrictions, further described as follows:
< ul >
2017-12-02 10:34:58 +00:00
< li > The palette file must be at least 792 bytes long. Colours are stored
2010-08-02 11:16:42 +00:00
in 24-bit RGB, with the first byte for red, the second for green, the
third for blue, for a total of 3 bytes per colour.< / li >
< li > The first 384 bytes of the file (128 * 3) will be used for the NTSC
2017-12-02 10:34:58 +00:00
palette. The next 384 bytes (128 * 3) will be for the PAL palette.
2010-08-02 11:16:42 +00:00
The next 24 bytes (8 * 3) will be for the SECAM palette, which
2017-12-02 10:34:58 +00:00
consists of eight distinct colours. Any extra data in the file
2010-08-02 11:16:42 +00:00
will be ignored.< / li >

< H2 > Preamble< / H2 >
< P >
The licenses for most software are designed to take away your
2017-12-02 10:34:58 +00:00
freedom to share and change it. By contrast, the GNU General Public
2002-04-22 01:45:08 +00:00
License is intended to guarantee your freedom to share and change free
2017-12-02 10:34:58 +00:00
software--to make sure the software is free for all its users. This
2002-04-22 01:45:08 +00:00
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
2017-12-02 10:34:58 +00:00
using it. (Some other Free Software Foundation software is covered by
2002-04-22 01:45:08 +00:00
the GNU Library General Public License instead.) You can apply it to
your programs, too.
< / P >
< P >
When we speak of free software, we are referring to freedom, not
2017-12-02 10:34:58 +00:00
price. Our General Public Licenses are designed to make sure that you
2002-04-22 01:45:08 +00:00
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.
< / P >
< P >
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.
< / P >
< P >
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
2017-12-02 10:34:58 +00:00
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
2002-04-22 01:45:08 +00:00
rights.
< / P >
< P >
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.
< / P >
< P >
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
2017-12-02 10:34:58 +00:00
software. If the software is modified by someone else and passed on, we
2002-04-22 01:45:08 +00:00
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.
< / P >
< P >
Finally, any free program is threatened constantly by software
2017-12-02 10:34:58 +00:00
patents. We wish to avoid the danger that redistributors of a free
2002-04-22 01:45:08 +00:00
program will individually obtain patent licenses, in effect making the
2017-12-02 10:34:58 +00:00
program proprietary. To prevent this, we have made it clear that any
2002-04-22 01:45:08 +00:00
patent must be licensed for everyone's free use or not licensed at all.
< / P >
< P >
The precise terms and conditions for copying, distribution and
modification follow.
< / P >
< H2 > TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION< / H2 >
< P >
< STRONG > 0.< / STRONG >
This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
2017-12-02 10:34:58 +00:00
under the terms of this General Public License. The "Program", below,
2002-04-22 01:45:08 +00:00
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
2017-12-02 10:34:58 +00:00
language. (Hereinafter, translation is included without limitation in
2002-04-22 01:45:08 +00:00
the term "modification".) Each licensee is addressed as "you".
< P >
Activities other than copying, distribution and modification are not
2017-12-02 10:34:58 +00:00
covered by this License; they are outside its scope. The act of
2002-04-22 01:45:08 +00:00
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.
< P >
< STRONG > 1.< / STRONG >
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.
< P >
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.
< P >
< STRONG > 2.< / STRONG >
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:
< P >
< UL >
< LI > < STRONG > a)< / STRONG >
You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
< P >
< LI > < STRONG > b)< / STRONG >
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.
< P >
< LI > < STRONG > c)< / STRONG >
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
2017-12-02 10:34:58 +00:00
License. (Exception: if the Program itself is interactive but
2002-04-22 01:45:08 +00:00
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
< / UL >
2017-12-02 10:34:58 +00:00
These requirements apply to the modified work as a whole. If
2002-04-22 01:45:08 +00:00
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
2017-12-02 10:34:58 +00:00
sections when you distribute them as separate works. But when you
2002-04-22 01:45:08 +00:00
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.
< P >
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.
< P >
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.
< P >
< STRONG > 3.< / STRONG >
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:
<!-- we use this doubled UL to get the sub - sections indented, -->
<!-- while making the bullets as unobvious as possible. -->
< UL >
< LI > < STRONG > a)< / STRONG >
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,
< P >
< LI > < STRONG > b)< / STRONG >
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,
< P >
< LI > < STRONG > c)< / STRONG >
Accompany it with the information you received as to the offer
2017-12-02 10:34:58 +00:00
to distribute corresponding source code. (This alternative is
2002-04-22 01:45:08 +00:00
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.)
< / UL >
The source code for a work means the preferred form of the work for
2017-12-02 10:34:58 +00:00
making modifications to it. For an executable work, complete source
2002-04-22 01:45:08 +00:00
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
2017-12-02 10:34:58 +00:00
control compilation and installation of the executable. However, as a
2002-04-22 01:45:08 +00:00
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.
< P >
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.
< P >
< STRONG > 4.< / STRONG >
You may not copy, modify, sublicense, or distribute the Program
2017-12-02 10:34:58 +00:00
except as expressly provided under this License. Any attempt
2002-04-22 01:45:08 +00:00
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.
< P >
< STRONG > 5.< / STRONG >
You are not required to accept this License, since you have not
2017-12-02 10:34:58 +00:00
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
2002-04-22 01:45:08 +00:00
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.
< P >
< STRONG > 6.< / STRONG >
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
2017-12-02 10:34:58 +00:00
these terms and conditions. You may not impose any further
2002-04-22 01:45:08 +00:00
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
< P >
< STRONG > 7.< / STRONG >
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
2017-12-02 10:34:58 +00:00
excuse you from the conditions of this License. If you cannot
2002-04-22 01:45:08 +00:00
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
2017-12-02 10:34:58 +00:00
may not distribute the Program at all. For example, if a patent
2002-04-22 01:45:08 +00:00
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.
< P >
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.
< P >
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
2017-12-02 10:34:58 +00:00
implemented by public license practices. Many people have made
2002-04-22 01:45:08 +00:00
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.
< P >
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
< P >
< STRONG > 8.< / STRONG >
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
2017-12-02 10:34:58 +00:00
countries not thus excluded. In such case, this License incorporates
2002-04-22 01:45:08 +00:00
the limitation as if written in the body of this License.
< P >
< STRONG > 9.< / STRONG >
The Free Software Foundation may publish revised and/or new versions
2017-12-02 10:34:58 +00:00
of the General Public License from time to time. Such new versions will
2002-04-22 01:45:08 +00:00
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
< P >
2017-12-02 10:34:58 +00:00
Each version is given a distinguishing version number. If the Program
2002-04-22 01:45:08 +00:00
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
2017-12-02 10:34:58 +00:00
Software Foundation. If the Program does not specify a version number of
2002-04-22 01:45:08 +00:00
this License, you may choose any version ever published by the Free Software
Foundation.
< P >
< STRONG > 10.< / STRONG >
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
2017-12-02 10:34:58 +00:00
to ask for permission. For software which is copyrighted by the Free
2002-04-22 01:45:08 +00:00
Software Foundation, write to the Free Software Foundation; we sometimes
2017-12-02 10:34:58 +00:00
make exceptions for this. Our decision will be guided by the two goals
2002-04-22 01:45:08 +00:00
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
< P > < STRONG > NO WARRANTY< / STRONG > < / P >

< STRONG > 11.< / STRONG >
BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
2017-12-02 10:34:58 +00:00
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
2002-04-22 01:45:08 +00:00
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
2017-12-02 10:34:58 +00:00
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
2002-04-22 01:45:08 +00:00
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
< P >
< STRONG > 12.< / STRONG >
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.
