GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. 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
them 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 prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. 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.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey 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;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If 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 convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU 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 that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
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.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
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.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
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
state 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>

Virtual Jaguar v2.1.0 Qt release INSTALL
----------------------------------------
REQUIREMENTS:
-------------
The minimum requirements for compiling Virtual Jaguar from source are:
o GCC v4.4.x or higher
o SDL v1.2.14 or higher
o zlib v1.2.5
o libcdio v0.90 or higher (optional, for Jaguar CD support)
o OpenGL libraries
o Qt 4.7.3 or higher
o supported OS (BeOS, Linux, FreeBSD and WIN32 through mingw, MacOS); other
OSs may work to but you may need to change some items in the Makefile.
COMPILING:
----------
Assuming that you meet the minimum software requirements, you can compile
Virtual Jaguar by issuing the following command in the directory where you
decompressed the source:
make
Optionally you can manually strip virtualjaguar[.exe] to downsize the binary.
You can also run upx on the binary as well and you'll end up with a somewhat
smaller binary.
That's it! You can now start the emulator with ./virtualjaguar. See the built
in help (Help|Contents) for more info.
For even more info, go to http://icculus.org/virtualjaguar.

----------------------------------------------------------------
- IMPORTANT NOTE ABOUT JAGUAR FILE FORMATS--READ THIS OR ELSE! -
----------------------------------------------------------------
There seems to be a lot of confusion surrounding the various file formats that
Jaguar programs come in, and a lot of this confusion seem to come from
Cowering's GoodJag renaming tool. Note that it simply gets some files wrong,
and it also incorrectly renames cartridge images with an extension that
belongs to an already established extension (.jag is a Jaguar Server
executable--read on). To clarify, there are basically four major types of
Jaguar binary images that are NOT cartridge images:
.abs
.jag
.rom
.bin
The first type, the .abs file, is a DRI/Alcyon format absolute location
executable. These come in two different flavors and contain load and run
addresses in their headers. Note that some files which have an .abs extension
are really incorrectly labelled .bin files with no header information
whatsoever.
The second type, the .jag file, is a Jaguar Server executable. These files
contain header information that tells you where to load and run the file's
executable code. Note that as of this writing (8/5/2005) that the GoodJag ROM
renaming tool by Cowering incorrectly renames Jaguar cartridge ROM dumps to
have a .jag extension (a better choice, and the one supported by Virtual
Jaguar, is .j64)--if you're trying to run a ROM image with a .jag extension on
VJ, it will misinterpret it as a Jaguar Server executable and likely fail to
run.
The third type, the .rom file, is an Alpine Board/ROM Image file. These files
have no header, but are known to load and run at $802000 in the Jaguar memory
space. Again, these are *different* from cartridge dumps since they load at a
higher address than a Jaguar cartridge.
The fourth type, the .bin file, is simply a Jaguar executable with no header.
Since these files contain no information about where they load and execute,
Virtual Jaguar does not support this file type. Go bug the author to release
either a file with proper headers or a file in Alpine ROM format. Virtual
Jaguar is not omniscient (yet)! ;)
There is a fifth type of file that is supported by Virtual Jaguar, the .j64
file, which is simply a 1, 2, or 4 Meg dump of a Jaguar cartridge ROM which
loads at $800000 in the Jaguar memory space.
----------------------------------
- What is Virtual Jaguar GCC/Qt? -
----------------------------------
Virtual Jaguar is software dedicated to emulating the Atari Jaguar hardware on
a standard PC. The software was originally developed by David Raingeard of
Potato Emulation [http://potato.emu-france.com] and was released under the GPL
on 25 June 2003.
Virtual Jaguar GCC/Qt is not just a port of the MS Visual C++/SDL sourcecode
but has also been extended and rewritten so that we can enjoy Atari Jaguar
emulation on every platform that has a GCC compiler and a port of Qt.
Currently Virtual Jaguar GCC/Qt compiles on WIN32 using mingw, and several
UN*X based systems (BeOS, Linux, FreeBSD and MacOS). It may run on other
systems as well but we can not guarantee that.
The port was done by the SDLEMU crew (http://sdlemu.ngemu.com) and especially
by Niels Wagenaar and Carwin Jones. A major portion of the rewrite was done by
James Hammons. You may contact us by e-mail ([email protected]) or leave a
message on the SDLEMU Official Forum (see the website). Patches and bugfixes
are particularly welcome! :)
More information about the incredible SDL libraries can be found at
http://www.libsdl.org. Thanks Sam--you rock! :)
-------------------------------
- Using Virtual Jaguar GCC/Qt -
-------------------------------
Simply double click on the Virtual Jaguar icon or type ./virtualjaguar -h from
the command line. See the built in help (under Help|Contents) for more
information on how to use it. :-)

- Finally -
-----------
If you find bugs, enhance the code or simply have questions, drop us an e-mail
at sdlemu AT ngemu DOT com or drop a message on the SDLEMU Official Forum.
More information about this project (releases/WIP) can be found at the official
Virtual Jaguar website [http://www.icculus.org/virtualjaguar] and on the SDLEMU
website [http://sdlemu.ngemu.com].
We hope you enjoy the emulator and will use it wisely!
Thanks go to guys over at ngemu.com and #ngemu (EFNET). Thanks also to David
Raingeard of Potato Emulation who originally developed this emulator and
released the sources to the public. We couldn't have done it without you!
Special thanks go to everyone who submitted good, detailed bug reports,
sometimes with demonstration code(!); your help has helped to make Virtual
Jaguar better, more accurate, and more polished than it would be otherwise. We
really appreciate your help!

Stuff to add/fix for the next release of Virtual Jaguar
-------------------------------------------------------
- Fix VC behavior to match what a real Jaguar does. Still not sure just what
the heck is going on there. [Shamus]
- Create an EEPROMs directory (or whatever is in EEPROMPath[]) if it doesn't
already exist. [Shamus]
- It would be nice to have the emulator pick up where you last left off, or at
least give you the option of continuing from your last session. This would
require save states, 'natch. ;-) [Shamus]
- It would be nice to have "save states" for instant save/load capability.
[Shamus]
- Cycle accuracy for GPU/DSP/OP/Blitter. [Shamus]
- Need to propagate blitter fixes in the A1 <- A2 direction to the A1 -> A2
direction and the GPU fixes to various instructions to the DSP. [Shamus]
- Blitter needs fixing. [Shamus]
- In emulator screenshots. [Shamus]
- Audio/video dumping. [Shamus]
- Need to emulate bus contention. [Shamus]
- Need to fix timing in the OP. As it is now, it gives a false impression of
how much it's capable of. [Shamus]
- Fix coming out of fullscreen on Win32. As of now, it doesn't restore the
window position correctly [CJ]
Stuff that was added/fixed
--------------------------
- Controller handling. [Shamus] [DONE--Shamus]
- Full screen option. [Shamus] [DONE--Shamus]
- Command line switches for frontends. [Shamus] [DONE-Shamus]
- Fix DSP code so that it doesn't hang in a spinlock waiting for the sound
buffer to empty. Probably a CS lock contention issue. [Shamus] [DONE-Shamus]
- Need to fix PAL mode to work with the virtual screen code. [DONE--Shamus]
- There are a few ROMs that use some "quasi-illegal" 68K instructions. Need
to patch the 68K core to deal with these in a better way than they are
now. [DONE--Shamus]
NOTE: This behavior was verified on Rayman, the problem was due to attempting
to press both left & right at the same time!
- We need a comprehensive way of determining what gets written where and
by whom (i.e., blitter wrote to range $F03000-$F03230) in order to figure
out the remaining problems with various ROMs. [DONE--Shamus]
- Would also be nice to be able to dynamically change the keybindings for
the various keys on the emulated Jaguar controller while inside the emulator.
[DONE--Shamus]
- Make sure that VJ doesn't crash if the useJaguarBIOS key is set to 1 and the
BIOS file isn't available. [DONE--Shamus]
- There is a bug either with the GPU or the blitter (most likely the latter)
which causes the spinning "A"s in the BIOS startup code to be corrupted
when they are showing their backsides. [Shamus] [DONE--Shamus]
NOTE: This behavior has been verified on a real Jaguar and as such is not
an emulator bug. A Jaguar boot ROM bug, yes, but not ours. ;-)
- Make it possible to completely disable the GUI (using a switch like -nogui
or the like) for people running VJ in a cabinet. [Shamus] [DONE--Shamus]
- Code to stretch the display in a generic way would be nice. [Shamus]
[DONE for OpenGL--nwagenaar]
- Would be nice to have a GUI for things that are set on the command line or
in the config file. [Shamus] [DONE--Shamus]
- DSP code needs to be rewritten. [Shamus] [DONE but still work to be done--Shamus]
- We need to have an external configuration file for remembering a user's
preferences, such as key bindings, etc. [Shamus] [DONE--Shamus]
- We need to come up with a way to fix the aspect ratio for pixel modes that
aren't square (PWIDTH != 4). [Shamus] [DONE for OpenGL--Shamus]
- GUI for ROM selection [Shamus] [DONE--Shamus]
- Need to rewrite the main Jaguar execution loop to increment the VC by one
instead of by two, which is how the real Jaguar works. [Shamus] [DONE--Shamus]
- Sound needs a rewrite. With SDL, this shouldn't be much of a problem.
Of course, whoever does this should realize that the PCM outs are probably
not being used for a majority of the ROMs out there--according to the JTRM,
you're supposed to use the I2S interface to output sound since the PCM outs
aren't even physically hooked up in the console! [Shamus] [DONE--Shamus]

Virtual Jaguar v2.1.0 GCC/Qt
----------------------------
* Added gamepad support. [Shamus]
* Added fullscreen option. [Shamus]
* Added some more developer goodies to Alpine mode. [Shamus]
* Re-added command line switches. [Shamus]
* Moved JERRY into host audio IRQ. This should make sound much smoother, though
it may run ahead of the rest of the emulator. [Shamus]
* Kludged a fix into the audio handler to set the correct frequency for audio
playback. Note that there could still be problems with this approach, as it
can be easily fooled. Thanks to Dr. Typo for the initial analysis and insight
into this bug. :-) [Shamus]
* Preliminary fixes for proper emulation of memory reads between $200000 and
$800000. [Shamus]
* Proper handling in the OP of objects with 0 IWIDTH. [Shamus]
Virtual Jaguar v2.0.2 GCC/Qt
----------------------------
* Fixed problem on OP with 24BPP bitmaps. [Shamus]
* Cosmetic GUI fixes. [Shamus]
* Switched to UAE 68000 CPU core. [Shamus]
* Fixed some RISC STORE and LOAD alignment issues. Still need to verify against
real hardware. [Shamus]
* Fixed video frame timing for both NTSC *and* PAL. [Shamus]
* Improved OP logging, added emulation of OP bug. [Shamus]
* Fixed addressing bug with UAE 68000 core. [Shamus]
Virtual Jaguar v2.0.1 GCC/Qt
----------------------------
* Fixed NTSC timings; they were hardwired to PAL rates. [Shamus]
* Fixed possible missing trailing slash on path fields input by user. [Shamus]
* Fixed exit hotkey to work on Win32. [Shamus]
* Changed PAL/NTSC switch to only work when virtual machine is powered off.
[Shamus]
* Miscellaneous documentation fixes. [Shamus]
Virtual Jaguar v2.0.0 GCC/Qt
----------------------------
* Switched GUI to Qt. And there was much rejoicing. ;-) [Shamus]
* Added detection code to fish out files from inside ZIP archives. What this
means is that now you can have other goodies inside of your ROM ZIP like
labels, box art, and overlays. See built-in help for details. [Shamus]
* Various usability improvements, too many to list here. ;-) [Shamus]
* Various compatibility improvements to the Jaguar core, too many to list
here. ;-) [Shamus]
Virtual Jaguar v1.1.0 GCC/SDL (r299 - Never officially released)
----------------------------------------------------------------
* Switched OpenGL rendering to 32 BPP. This is not only how a real Jaguar
renders graphics, but it also gives VJ a nice speed boost. ;-) [Shamus]
* Changed execution to a time-based solution so that timers and IRQs and
such can happen when they're supposed to. [Shamus]
* Fixed blitter writes so that Intensity[0-3] and Z[0-3] are written in the
correct order. [Shamus]
* Major rewrite of blitter to conform the the TOM ASIC nets. This should fix a
bunch of stuff that wasn't working correctly before. [Shamus]
* Fixed writes to 64 bit blitter registers. [Shamus]
* Refactored GUI to be more maintainable, better looking and more responsive.
[Shamus]
Virtual Jaguar v1.0.7 GCC/SDL
-----------------------------
* Various fixes to make for smoother compilation on MacOS. [Adam Green]
* Fixes to filetype parsing. VJ now properly recognizes .abs, .jag, .rom,
and .j64 files--be sure to check the README for the gory details! [Shamus]
* Added a kludge to allow homebrew demos to run without a Stubulator ROM and
without crashing the emulator. [Shamus]
* Fixed a blitter intensity addition problem. This fixes the title in Hover
Strike and the road/shadows in Checkered Flag. [Shamus]
* Partially fixed a problem with the SUBC opcode in the RISC processors. This
allows Hover Strike, Phase Zero and Fight For Life to boot into their title
screens and makes them somewhat playable. [Shamus]
* Fixed a horizontal scaling problem in the OP and the off-by-one bug that it
reintroduced. This fixes the road in Atari Karts and probably a few others.
[Shamus]
* Fixed a long standing blitter bug that kept certain doors in AvP from
rendering correctly. [Shamus]
* Fixed some vertical positioning bugs in the OP. Now Checkered Flag, Alien
vs Predator and probably others now work as they should (graphically ;-)
[Caz]
* Better GUI support. Most options in the GUI work now, and more are expected
to be functional in the near future. [Shamus]
* Fixed a few more lingering blitter bugs (there are more to be found). This
fixes most of the glitches in Cybermorph and Alien vs Predator. [Shamus]
* Fixed an Object Processor scaled bitmap bug that caused incorrect
positioning of scaled bitmaps that started outside the line buffer, and
also fixed a problem that caused the OP to hang in certain situations. This
fixes Bubsy, International Sensible Soccer, and probably a few others.
[Shamus]
* Cleaned up various bits of video rendering related code. [nwagenaar]
* Added support for OpenGL textures with a depth of 16bpp, 24bpp or 32bpp.
[nwagenaar]
* Rewrote several OpenGL related rendering code concerning the new OpenGL
texture depths and texture sizes. [nwagenaar]
* Rewrote several OpenGL rendering functions concerning speed related items.
[nwagenaar]
* Several bugs resolved due to OpenGL and normal rendering code. [nwagenaar]
* Default resolution for OpenGL is now 640x480. [nwagenaar]
Virtual Jaguar v1.0.6 GCC/SDL
-----------------------------
* Added support for gzipped ROM files. [Adam Green]
* Added OpenGL support. Because of this, aspect ratios in the various
graphic modes should be correct now. Thanks goes to Niels for enlightenment
in this area. :-) [Shamus]
* Moved all platform specific video code to video.cpp. This should make it
easier to add functionality to the video subsystem without having to chase
code around in places where it didn't belong. [Shamus]
* Key bindings are now customizable. [Shamus]
* VJ now uses a config file (vj.cfg) for commonly used settings. Settings in
the config file can still be overridden by command line switches. [Shamus]
* Preliminary GUI mouse support. [Shamus]
* Fixed an off-by-one bug in the Object Processor when dealing with scaled
bitmap objects. [Shamus]
* Fully virtualized screen size. What this means is that we can keep the
Jagaur screen displayed in a convenient size (320 x 240) and the graphics
that various ROMs display will now be properly centered (more or less, they
were really centered for a TV display). [Shamus]
* Border color is now displayed properly. [Shamus]
* Fully pipelined DSP core. Because of this, Wolfenstein 3D now has sound. To
use the old core, use the -nopipeline switch. [Shamus]
Virtual Jaguar v1.0.5 GCC/SDL
-----------------------------
* Various fixes to the codebase so that it compiles and works properly on
Linux. :-) The makefiles are almost identical now, the only thing that's
different between them are the SYSTYPE and EXESUFFIX variables defined at
the top. [Shamus]
* Fixed a pernicious blitter bug that kept Rayman from doing proper collision
detection. [Shamus]
* Added a simple file selector so that typing in long filenames in order to
run the emulator is no longer necessary. :-) To use it, instead of
supplying a ROM name, simply put in the name of the directory where your
ROMs live. [Shamus]
* Removed all the assembly language code from the DSP, so it should be a
little less buggy now. Also, removed some brain-dead timeslice releasing
that was causing a bunch of problems with various ROMs. [Shamus]
* Added sound support! In order to hear any sound, you probably have to
start VJ with the -dspon switch. Also, unless you have a very fast computer
the sound is going to be choppy. Hopefully future optimizations will cure
this. ;-) [Shamus]
* Added GUI support. You can see the results by hitting the TAB key while the
emulator is running. ;-) [Shamus]
* Lots of cleanups to the source code including the ability to trace who
writes what to where. [Shamus]
Virtual Jaguar v1.0.4 GCC/SDL - source only release
---------------------------------------------------
* Lots of bugfixes. [Shamus]
* Jaguar BIOS now works properly and is used by default. BIOS failure was
due to a bug in the GPU (specifically in the SUBC and ADDC opcodes). To
override this behavior, use the -nobios switch. [Shamus]
* Rewrote the OP code--mostly because it was pissing me off. ;-) Not
to mention that it was almost completely unmaintainable in its former
state and was just plain wrong in its implementation in many places.
Because of this, some RMW effects that were missing from AvP are present
now and leftover crud in scaled bitmaps in Rayman is gone now. ;-) [Shamus]
* ZIP support! Now there is no longer any need to unzip ROMs (although if
you prefer to waste HD space, VJ will gladly accomodate you). The code to
support this is a pretty ugly hack, but it works and there are other fish
to fry at the moment. Also, ZLIB is now required to compile VJ. [Shamus]
* Support for PD ROMs. Currently the only one that works at all is JagMania,
though as the hardware emulation gets better more PD ROMs will begin to
work. Note that you must use the -nobios switch for this to work. [Shamus]
* Preliminary support for PAL Jaguar emulation. Default is NTSC. To use it,
use the -pal switch. [Shamus]
* Support for DSP activation. The DSP is now *off* by default, since it
doesn't work properly yet. Use the -dspon switch to force the DSP on.
[Shamus]
* Removed all hacks that were written to support a specific ROM from the OP
and GPU code (much more remains to be removed). Since the CRCs that were
calculated to support these hacks were done on byte swapped ROMs, they
weren't working anyway. Besides which, a hack means that you don't
understand the hardware properly and/or don't know how to write the code to
properly emulate the hardware. ;-) [Shamus]
* Renamed the executable from the ridiculously named jag_em to the more
sensibly named vj. Note that the Jag_em.cpp file has also been changed to
reflect this name change. [Shamus]
* Removed Aaron Giles 68K dissasembler in favor of the one included with the
Musashi core. It's there, why not use it? ;-) [Shamus]
* Reordered the order of A, B, and C buttons to more accurately reflect their
respective positions on a real Jaguar controller. Also fixed a small bug that
kept the number pad from reporting the right numbers to the emulator. :-)
[Shamus]
* Started to remove the !__PORT__ defintions from the source code. Since this
is supposed to be a portable emulator, we won't be using any MS specific
code anyway. [Shamus]
* Fixed some problems with the blitter when doing clipping and bit expansion.
Also fixed (reintroduced?) a bug that existed in the real blitter HW (the
YADD1 bit in A2--fixes Tempest 2000). [Shamus]
* Probably a bunch of other stuff that I've forgotten about. ;-) [Shamus]
NOTE: Tested only on WIN32 platform! ;-)
Virtual Jaguar v1.0.3 GCC/SDL - source only release
---------------------------------------------------
* Converted GNU assembly in the GPU core to C code -- Rayman and
Alien vs Predator work again. :-) [Shamus]
* Removed closed source Starscream and replaced it with the open source
Musashi core. Because of this, VJ runs a little faster now. :-) [Shamus]
* Various cleanups to the source files (still lots of work to do!). [Shamus]
NOTE: Tested only on WIN32 platform!
1.0.1 - 1.0.2 - Unreleased, mostly for testing/finding bugs
-----------------------------------------------------------
* Lots of stuff happened, but we can't remember any of it. :-)
Virtual Jaguar v1.0.0 GCC/SDL - initial source release
------------------------------------------------------
* Converted VC++ assembly to standard GNU assembly.
* Fixed small bugs in SDL related items (keyboard/graphics).
* Added *some* optimalisations to the graphics sources.
* Added joystick support (not tested).
* Added joystick port support (not tested).
* Added frameskip support.
Source only release. Tested on BeOS, Linux, FreeBSD and WIN32.
SOUND emulation was NOT done. Need help with this one :)
