GNU GENERAL PUBLIC LICENSE
|
|
||||||
Version 2, June 1991
|
|
||||||
|
|
||||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
|
||||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
|
||||||
Everyone is permitted to copy and distribute verbatim copies
|
|
||||||
of this license document, but changing it is not allowed.
|
|
||||||
|
|
||||||
Preamble
|
|
||||||
|
|
||||||
The licenses for most software are designed to take away your
|
|
||||||
freedom to share and change it. By contrast, the GNU General Public
|
|
||||||
License is intended to guarantee your freedom to share and change free
|
|
||||||
software--to make sure the software is free for all its users. This
|
|
||||||
General Public License applies to most of the Free Software
|
|
||||||
Foundation's software and to any other program whose authors commit to
|
|
||||||
using it. (Some other Free Software Foundation software is covered by
|
|
||||||
the GNU Library General Public License instead.) You can apply it to
|
|
||||||
your programs, too.
|
|
||||||
|
|
||||||
When we speak of free software, we are referring to freedom, not
|
|
||||||
price. Our General Public Licenses are designed to make sure that you
|
|
||||||
have the freedom to distribute copies of free software (and charge for
|
|
||||||
this service if you wish), that you receive source code or can get it
|
|
||||||
if you want it, that you can change the software or use pieces of it
|
|
||||||
in new free programs; and that you know you can do these things.
|
|
||||||
|
|
||||||
To protect your rights, we need to make restrictions that forbid
|
|
||||||
anyone to deny you these rights or to ask you to surrender the rights.
|
|
||||||
These restrictions translate to certain responsibilities for you if you
|
|
||||||
distribute copies of the software, or if you modify it.
|
|
||||||
|
|
||||||
For example, if you distribute copies of such a program, whether
|
|
||||||
gratis or for a fee, you must give the recipients all the rights that
|
|
||||||
you have. You must make sure that they, too, receive or can get the
|
|
||||||
source code. And you must show them these terms so they know their
|
|
||||||
rights.
|
|
||||||
|
|
||||||
We protect your rights with two steps: (1) copyright the software, and
|
|
||||||
(2) offer you this license which gives you legal permission to copy,
|
|
||||||
distribute and/or modify the software.
|
|
||||||
|
|
||||||
Also, for each author's protection and ours, we want to make certain
|
|
||||||
that everyone understands that there is no warranty for this free
|
|
||||||
software. If the software is modified by someone else and passed on, we
|
|
||||||
want its recipients to know that what they have is not the original, so
|
|
||||||
that any problems introduced by others will not reflect on the original
|
|
||||||
authors' reputations.
|
|
||||||
|
|
||||||
Finally, any free program is threatened constantly by software
|
|
||||||
patents. We wish to avoid the danger that redistributors of a free
|
|
||||||
program will individually obtain patent licenses, in effect making the
|
|
||||||
program proprietary. To prevent this, we have made it clear that any
|
|
||||||
patent must be licensed for everyone's free use or not licensed at all.
|
|
||||||
|
|
||||||
The precise terms and conditions for copying, distribution and
|
|
||||||
modification follow.
|
|
||||||
|
|
||||||
GNU GENERAL PUBLIC LICENSE
|
|
||||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
|
||||||
|
|
||||||
0. This License applies to any program or other work which contains
|
|
||||||
a notice placed by the copyright holder saying it may be distributed
|
|
||||||
under the terms of this General Public License. The "Program", below,
|
|
||||||
refers to any such program or work, and a "work based on the Program"
|
|
||||||
means either the Program or any derivative work under copyright law:
|
|
||||||
that is to say, a work containing the Program or a portion of it,
|
|
||||||
either verbatim or with modifications and/or translated into another
|
|
||||||
language. (Hereinafter, translation is included without limitation in
|
|
||||||
the term "modification".) Each licensee is addressed as "you".
|
|
||||||
|
|
||||||
Activities other than copying, distribution and modification are not
|
|
||||||
covered by this License; they are outside its scope. The act of
|
|
||||||
running the Program is not restricted, and the output from the Program
|
|
||||||
is covered only if its contents constitute a work based on the
|
|
||||||
Program (independent of having been made by running the Program).
|
|
||||||
Whether that is true depends on what the Program does.
|
|
||||||
|
|
||||||
1. You may copy and distribute verbatim copies of the Program's
|
|
||||||
source code as you receive it, in any medium, provided that you
|
|
||||||
conspicuously and appropriately publish on each copy an appropriate
|
|
||||||
copyright notice and disclaimer of warranty; keep intact all the
|
|
||||||
notices that refer to this License and to the absence of any warranty;
|
|
||||||
and give any other recipients of the Program a copy of this License
|
|
||||||
along with the Program.
|
|
||||||
|
|
||||||
You may charge a fee for the physical act of transferring a copy, and
|
|
||||||
you may at your option offer warranty protection in exchange for a fee.
|
|
||||||
|
|
||||||
2. You may modify your copy or copies of the Program or any portion
|
|
||||||
of it, thus forming a work based on the Program, and copy and
|
|
||||||
distribute such modifications or work under the terms of Section 1
|
|
||||||
above, provided that you also meet all of these conditions:
|
|
||||||
|
|
||||||
a) You must cause the modified files to carry prominent notices
|
|
||||||
stating that you changed the files and the date of any change.
|
|
||||||
|
|
||||||
b) You must cause any work that you distribute or publish, that in
|
|
||||||
whole or in part contains or is derived from the Program or any
|
|
||||||
part thereof, to be licensed as a whole at no charge to all third
|
|
||||||
parties under the terms of this License.
|
|
||||||
|
|
||||||
c) If the modified program normally reads commands interactively
|
|
||||||
when run, you must cause it, when started running for such
|
|
||||||
interactive use in the most ordinary way, to print or display an
|
|
||||||
announcement including an appropriate copyright notice and a
|
|
||||||
notice that there is no warranty (or else, saying that you provide
|
|
||||||
a warranty) and that users may redistribute the program under
|
|
||||||
these conditions, and telling the user how to view a copy of this
|
|
||||||
License. (Exception: if the Program itself is interactive but
|
|
||||||
does not normally print such an announcement, your work based on
|
|
||||||
the Program is not required to print an announcement.)
|
|
||||||
|
|
||||||
These requirements apply to the modified work as a whole. If
|
|
||||||
identifiable sections of that work are not derived from the Program,
|
|
||||||
and can be reasonably considered independent and separate works in
|
|
||||||
themselves, then this License, and its terms, do not apply to those
|
|
||||||
sections when you distribute them as separate works. But when you
|
|
||||||
distribute the same sections as part of a whole which is a work based
|
|
||||||
on the Program, the distribution of the whole must be on the terms of
|
|
||||||
this License, whose permissions for other licensees extend to the
|
|
||||||
entire whole, and thus to each and every part regardless of who wrote it.
|
|
||||||
|
|
||||||
Thus, it is not the intent of this section to claim rights or contest
|
|
||||||
your rights to work written entirely by you; rather, the intent is to
|
|
||||||
exercise the right to control the distribution of derivative or
|
|
||||||
collective works based on the Program.
|
|
||||||
|
|
||||||
In addition, mere aggregation of another work not based on the Program
|
|
||||||
with the Program (or with a work based on the Program) on a volume of
|
|
||||||
a storage or distribution medium does not bring the other work under
|
|
||||||
the scope of this License.
|
|
||||||
|
|
||||||
3. You may copy and distribute the Program (or a work based on it,
|
|
||||||
under Section 2) in object code or executable form under the terms of
|
|
||||||
Sections 1 and 2 above provided that you also do one of the following:
|
|
||||||
|
|
||||||
a) Accompany it with the complete corresponding machine-readable
|
|
||||||
source code, which must be distributed under the terms of Sections
|
|
||||||
1 and 2 above on a medium customarily used for software interchange; or,
|
|
||||||
|
|
||||||
b) Accompany it with a written offer, valid for at least three
|
|
||||||
years, to give any third party, for a charge no more than your
|
|
||||||
cost of physically performing source distribution, a complete
|
|
||||||
machine-readable copy of the corresponding source code, to be
|
|
||||||
distributed under the terms of Sections 1 and 2 above on a medium
|
|
||||||
customarily used for software interchange; or,
|
|
||||||
|
|
||||||
c) Accompany it with the information you received as to the offer
|
|
||||||
to distribute corresponding source code. (This alternative is
|
|
||||||
allowed only for noncommercial distribution and only if you
|
|
||||||
received the program in object code or executable form with such
|
|
||||||
an offer, in accord with Subsection b above.)
|
|
||||||
|
|
||||||
The source code for a work means the preferred form of the work for
|
|
||||||
making modifications to it. For an executable work, complete source
|
|
||||||
code means all the source code for all modules it contains, plus any
|
|
||||||
associated interface definition files, plus the scripts used to
|
|
||||||
control compilation and installation of the executable. However, as a
|
|
||||||
special exception, the source code distributed need not include
|
|
||||||
anything that is normally distributed (in either source or binary
|
|
||||||
form) with the major components (compiler, kernel, and so on) of the
|
|
||||||
operating system on which the executable runs, unless that component
|
|
||||||
itself accompanies the executable.
|
|
||||||
|
|
||||||
If distribution of executable or object code is made by offering
|
|
||||||
access to copy from a designated place, then offering equivalent
|
|
||||||
access to copy the source code from the same place counts as
|
|
||||||
distribution of the source code, even though third parties are not
|
|
||||||
compelled to copy the source along with the object code.
|
|
||||||
|
|
||||||
4. You may not copy, modify, sublicense, or distribute the Program
|
|
||||||
except as expressly provided under this License. Any attempt
|
|
||||||
otherwise to copy, modify, sublicense or distribute the Program is
|
|
||||||
void, and will automatically terminate your rights under this License.
|
|
||||||
However, parties who have received copies, or rights, from you under
|
|
||||||
this License will not have their licenses terminated so long as such
|
|
||||||
parties remain in full compliance.
|
|
||||||
|
|
||||||
5. You are not required to accept this License, since you have not
|
|
||||||
signed it. However, nothing else grants you permission to modify or
|
|
||||||
distribute the Program or its derivative works. These actions are
|
|
||||||
prohibited by law if you do not accept this License. Therefore, by
|
|
||||||
modifying or distributing the Program (or any work based on the
|
|
||||||
Program), you indicate your acceptance of this License to do so, and
|
|
||||||
all its terms and conditions for copying, distributing or modifying
|
|
||||||
the Program or works based on it.
|
|
||||||
|
|
||||||
6. Each time you redistribute the Program (or any work based on the
|
|
||||||
Program), the recipient automatically receives a license from the
|
|
||||||
original licensor to copy, distribute or modify the Program subject to
|
|
||||||
these terms and conditions. You may not impose any further
|
|
||||||
restrictions on the recipients' exercise of the rights granted herein.
|
|
||||||
You are not responsible for enforcing compliance by third parties to
|
|
||||||
this License.
|
|
||||||
|
|
||||||
7. If, as a consequence of a court judgment or allegation of patent
|
|
||||||
infringement or for any other reason (not limited to patent issues),
|
|
||||||
conditions are imposed on you (whether by court order, agreement or
|
|
||||||
otherwise) that contradict the conditions of this License, they do not
|
|
||||||
excuse you from the conditions of this License. If you cannot
|
|
||||||
distribute so as to satisfy simultaneously your obligations under this
|
|
||||||
License and any other pertinent obligations, then as a consequence you
|
|
||||||
may not distribute the Program at all. For example, if a patent
|
|
||||||
license would not permit royalty-free redistribution of the Program by
|
|
||||||
all those who receive copies directly or indirectly through you, then
|
|
||||||
the only way you could satisfy both it and this License would be to
|
|
||||||
refrain entirely from distribution of the Program.
|
|
||||||
|
|
||||||
If any portion of this section is held invalid or unenforceable under
|
|
||||||
any particular circumstance, the balance of the section is intended to
|
|
||||||
apply and the section as a whole is intended to apply in other
|
|
||||||
circumstances.
|
|
||||||
|
|
||||||
It is not the purpose of this section to induce you to infringe any
|
|
||||||
patents or other property right claims or to contest validity of any
|
|
||||||
such claims; this section has the sole purpose of protecting the
|
|
||||||
integrity of the free software distribution system, which is
|
|
||||||
implemented by public license practices. Many people have made
|
|
||||||
generous contributions to the wide range of software distributed
|
|
||||||
through that system in reliance on consistent application of that
|
|
||||||
system; it is up to the author/donor to decide if he or she is willing
|
|
||||||
to distribute software through any other system and a licensee cannot
|
|
||||||
impose that choice.
|
|
||||||
|
|
||||||
This section is intended to make thoroughly clear what is believed to
|
|
||||||
be a consequence of the rest of this License.
|
|
||||||
|
|
||||||
8. If the distribution and/or use of the Program is restricted in
|
|
||||||
certain countries either by patents or by copyrighted interfaces, the
|
|
||||||
original copyright holder who places the Program under this License
|
|
||||||
may add an explicit geographical distribution limitation excluding
|
|
||||||
those countries, so that distribution is permitted only in or among
|
|
||||||
countries not thus excluded. In such case, this License incorporates
|
|
||||||
the limitation as if written in the body of this License.
|
|
||||||
|
|
||||||
9. The Free Software Foundation may publish revised and/or new versions
|
|
||||||
of the General Public License from time to time. Such new versions will
|
|
||||||
be similar in spirit to the present version, but may differ in detail to
|
|
||||||
address new problems or concerns.
|
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the Program
|
|
||||||
specifies a version number of this License which applies to it and "any
|
|
||||||
later version", you have the option of following the terms and conditions
|
|
||||||
either of that version or of any later version published by the Free
|
|
||||||
Software Foundation. If the Program does not specify a version number of
|
|
||||||
this License, you may choose any version ever published by the Free Software
|
|
||||||
Foundation.
|
|
||||||
|
|
||||||
10. If you wish to incorporate parts of the Program into other free
|
|
||||||
programs whose distribution conditions are different, write to the author
|
|
||||||
to ask for permission. For software which is copyrighted by the Free
|
|
||||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
|
||||||
make exceptions for this. Our decision will be guided by the two goals
|
|
||||||
of preserving the free status of all derivatives of our free software and
|
|
||||||
of promoting the sharing and reuse of software generally.
|
|
||||||
|
|
||||||
NO WARRANTY
|
|
||||||
|
|
||||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
|
||||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
|
||||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
|
||||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
|
||||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
|
||||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
|
||||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
|
||||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
|
||||||
REPAIR OR CORRECTION.
|
|
||||||
|
|
||||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
|
||||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
|
||||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
|
||||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
|
||||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
|
||||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
|
||||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
|
||||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
|
||||||
POSSIBILITY OF SUCH DAMAGES.
|
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS
|
|
||||||
|
|
||||||
How to Apply These Terms to Your New Programs
|
|
||||||
|
|
||||||
If you develop a new program, and you want it to be of the greatest
|
|
||||||
possible use to the public, the best way to achieve this is to make it
|
|
||||||
free software which everyone can redistribute and change under these terms.
|
|
||||||
|
|
||||||
To do so, attach the following notices to the program. It is safest
|
|
||||||
to attach them to the start of each source file to most effectively
|
|
||||||
convey the exclusion of warranty; and each file should have at least
|
|
||||||
the "copyright" line and a pointer to where the full notice is found.
|
|
||||||
|
|
||||||
<one line to give the program's name and a brief idea of what it does.>
|
|
||||||
Copyright (C) 19yy <name of author>
|
|
||||||
|
|
||||||
This program is free software; you can redistribute it and/or modify
|
|
||||||
it under the terms of the GNU General Public License as published by
|
|
||||||
the Free Software Foundation; either version 2 of the License, or
|
|
||||||
(at your option) any later version.
|
|
||||||
|
|
||||||
This program is distributed in the hope that it will be useful,
|
|
||||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
|
||||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
|
||||||
GNU General Public License for more details.
|
|
||||||
|
|
||||||
You should have received a copy of the GNU General Public License
|
|
||||||
along with this program; if not, write to the Free Software
|
|
||||||
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
|
||||||
|
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail.
|
|
||||||
|
|
||||||
If the program is interactive, make it output a short notice like this
|
|
||||||
when it starts in an interactive mode:
|
|
||||||
|
|
||||||
Gnomovision version 69, Copyright (C) 19yy name of author
|
|
||||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
|
||||||
This is free software, and you are welcome to redistribute it
|
|
||||||
under certain conditions; type `show c' for details.
|
|
||||||
|
|
||||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
|
||||||
parts of the General Public License. Of course, the commands you use may
|
|
||||||
be called something other than `show w' and `show c'; they could even be
|
|
||||||
mouse-clicks or menu items--whatever suits your program.
|
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or your
|
|
||||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
|
||||||
necessary. Here is a sample; alter the names:
|
|
||||||
|
|
||||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
|
||||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

|
|
||||||
This General Public License does not permit incorporating your program into
|
|
||||||
proprietary programs. If your program is a subroutine library, you may
|
|
||||||
consider it more useful to permit linking proprietary applications with the
|
|
||||||
library. If this is what you want to do, use the GNU Library General
|
|
||||||
Public License instead of this License.

Genesis Plus has reasonable speed, and very fast rendering. Here are some
|
|
||||||
details about porting it to another platform
|
|
||||||
|
|
||||||
Porting rules
|
|
||||||
|
|
||||||
- This program is released under the GPL, so please release the source
|
|
||||||
code for your derivative ports. Let me know if you need an alternative
|
|
||||||
to this.
|
|
||||||
|
|
||||||
- Do not change the name of the emulator. Something like 'Genesis Plus / MacOS'
|
|
||||||
is fine as it keeps the original name.
|
|
||||||
|
|
||||||
- Configure the CPU emulators for little or big-endian CPUs, and use the
|
|
||||||
ALIGN_LONG option to handle unaligned memory accesses if needed. E.g. if
|
|
||||||
the emulator crashes when a game scrolls horizontally, you need to enable
|
|
||||||
it.
|
|
||||||
|
|
||||||
Requirements
|
|
||||||
|
|
||||||
- At this time the 16-bit rendering code has been well tested and should
|
|
||||||
be used. There is code to support 8 through 32-bit displays, but I
|
|
||||||
haven't checked if it still works.
|
|
||||||
|
|
||||||
- Audio output, if enabled, uses stereo 16-bit samples.
|
|
||||||
|
|
||||||
Functions to use:
|
|
||||||
|
|
||||||
int load_rom(char *filename);
|
|
||||||
|
|
||||||
Loads a game which can be in BIN, SMD or ZIP formats. It returns zero if
|
|
||||||
an error has occured.
|
|
||||||
|
|
||||||
void system_init(void);
|
|
||||||
|
|
||||||
Initializes the virtual Genesis console. Call this once during startup.
|
|
||||||
|
|
||||||
void audio_init(int rate);
|
|
||||||
|
|
||||||
Initialize the sound emulation part of the emulator. Pass zero or don't
|
|
||||||
call the function to disable sound. Call this after running system_init().
|
|
||||||
|
|
||||||
void system_reset(void);
|
|
||||||
|
|
||||||
Resets the virtual Genesis console. Call this once during setup, and later
|
|
||||||
as needed.
|
|
||||||
|
|
||||||
int system_frame(int skip);
|
|
||||||
|
|
||||||
Updates the emulation for a frame. Pass 1 to prevent rendering (which can
|
|
||||||
be used for frame skipping) and 0 to render the current display.
|
|
||||||
|
|
||||||
This function returns 0 if the virtual Genesis console has locked up.
|
|
||||||
You can do what you'd like with this information, such as notify the user,
|
|
||||||
reset the machine, etc.
|
|
||||||
|
|
||||||
If audio is enabled, the snd.buffer[] array will hold the current audio
|
|
||||||
data for this frame.
|
|
||||||
|
|
||||||
void system_shutdown(void);
|
|
||||||
|
|
||||||
Shuts down the emulator.
|
|
||||||
|
|
||||||
Variables:
|
|
||||||
|
|
||||||
The 'bitmap' structure needs to be filled out prior to calling system_init().
|
|
||||||
This provides the rendering code with information about the type of bitmap
|
|
||||||
it is rendering to. I would advise sticking with a 1024x512 16-bit bitmap:
|
|
||||||
|
|
||||||
memset(&bitmap, 0, sizeof(t_bitmap));
|
|
||||||
bitmap.width = 1024;
|
|
||||||
bitmap.height = 512;
|
|
||||||
bitmap.depth = 16;
|
|
||||||
bitmap.granularity = 2; /* Bytes per pixel */
|
|
||||||
bitmap.pitch = (bitmap.width * bitmap.granularity);
|
|
||||||
bitmap.data = (unsigned char *)bmp->pixels; /* Pointer to your bitmap */
|
|
||||||
bitmap.viewport.w = 256; /* Initial size of display on power-up (do not change) */
|
|
||||||
bitmap.viewport.h = 224;
|
|
||||||
bitmap.viewport.x = 0x20; /* Offset used for rendering (do not change) */
|
|
||||||
bitmap.viewport.y = 0x00;
|
|
||||||
bitmap.remap = 1;
|
|
||||||
|
|
||||||
The variable 'input.pad[0]' holds the button states for the first player
|
|
||||||
gamepad. Update this prior to calling system_frame(), and use the bitmasks
|
|
||||||
defined in system.h such as 'INPUT_UP', etc.
|
|
||||||
|
|
||||||
See the Windows/SDL and DOS drivers for examples.

|
||||||
The Windows version runs windowed in a 16-bit desktop with NO sound or
|
|
||||||
joystick support.
|
|
||||||
|
|
||||||
The DOS version has most of the functionality from SMS Plus, such
|
|
||||||
as audio, joysticks, etc.
|
|
||||||
|
|
||||||
Windows/DOS controls:
|
|
||||||
|
|
||||||
Arrow Keys - Directional pad
|
|
||||||
A,S,D,F - 1P gamepad, buttons A, B, C, Start
|
|
||||||
Tab - Reset
|
|
||||||
Esc - Exit program
|
|
||||||
|
|
||||||
DOS only:
|
|
||||||
|
|
||||||
End - Exit program
|
|
||||||
F1-F4 - Set frameskip level (F1 = no skip ... F4 = skip 3 frames)
|
|
||||||
F8 - Make PCX screen snapshot
|
|
||||||
F9 - Toggle VSync
|
|
||||||
F10 - Toggle speed throttling
|
|
||||||
F11 - Toggle FPS meter
|
|
||||||
|
|
||||||
DOS details:
|
|
||||||
|
|
||||||
You can only support a second player if you are using a joystick driver
|
|
||||||
that supports more than one joystick. (e.g. Sidewinder, dual pads, etc.)
|
|
||||||
|
|
||||||
Type 'gen -help' on the command line for a list of useful options.
|
|
||||||
|
|
||||||
-res <x> <y> set the display resolution.
|
|
||||||
-vdriver <n> specify video driver.
|
|
||||||
-depth <n> specify color depth. (8, 16)
|
|
||||||
-scanlines use scanlines effect.
|
|
||||||
-scale scale display to full resolution. (slow)
|
|
||||||
-vsync wait for vertical sync before blitting.
|
|
||||||
-sound enable sound. (force speed throttling)
|
|
||||||
-sndrate <n> specify sound rate. (8000, 11025, 22050, 44100)
|
|
||||||
-sndcard <n> specify sound card. (0-7)
|
|
||||||
-swap swap left and right stereo output.
|
|
||||||
-joy <s> specify joystick type.
|
|
||||||
|
|
||||||
Here is a list of all the video drivers you can pass as a parameter
|
|
||||||
to the '-vdriver' option:
|
|
||||||
|
|
||||||
auto, safe, vga, modex, vesa2l, vesa3, vbeaf
|
|
||||||
|
|
||||||
Here is a list of all the joystick drivers you can pass as a parameter
|
|
||||||
to the '-joy' option:
|
|
||||||
|
|
||||||
auto, none, standard, 2pads, 4button, 6button, 8button, fspro, wingex,
|
|
||||||
sidewinder, gamepadpro, grip, grip4, sneslpt1, sneslpt2, sneslpt3,
|
|
||||||
psxlpt1, psxlpt2, psxlpt3, n64lpt1, n64lpt2, n64lpt3, db9lpt1, db9lpt2,
|
|
||||||
db9lpt3, tglpt1, tglpt2, tglpt3, wingwar, segaisa, segapci, segapci2
|
|
||||||
|
|
||||||
You can put any commandline option into a plain text file which should
|
|
||||||
be called "gen.cfg". Put one option per line, please. Command line options
|
|
||||||
will override anything in the configuration file.
|
|
||||||
|
|
||||||
Currently the zip loading code can manage a zipfile where the game
|
|
||||||
image is the first thing in it. If you try to open a huge archive of
|
|
||||||
games, only the first will be played.

Here are some technical details about things that need to be fixed or
|
|
||||||
added to Genesis Plus.
|
|
||||||
|
|
||||||
Missing features:
|
|
||||||
|
|
||||||
- Support for 6-button controllers
|
|
||||||
- SRAM management
|
|
||||||
- Game Genie / PAR patch codes
|
|
||||||
|
|
||||||
The VDP code could use a lot of cleaning up.
|
|
||||||
|
|
||||||
The rendering code is missing a few bits:
|
|
||||||
|
|
||||||
- Sprite collision
|
|
||||||
- Window bug
|
|
||||||
|
|
||||||
I think the "C" 68000 emulator either has some bugs or I'm not using it
|
|
||||||
correctly. Older DOS-only versions used Turbo68K, which had ran games
|
|
||||||
much better, especially with regards to interrupt handling.
|
|
||||||
|
|
||||||
Things that need to be fixed:
|
|
||||||
|
|
||||||
- Raster garbage on third road in Thunder Blade.
|
|
||||||
|
|
||||||
- Added country codes for Dragon Slayer, but game locks up after
|
|
||||||
passing country check.
|
|
||||||
|
|
||||||
- No inputs in Samurai Shodown.
|
|
||||||
(This game doesn't initialize the port direction registers, at least not
|
|
||||||
directly. Emulation bug or problem with the game?)
|
|
||||||
|
|
||||||
- Palette and raster problems in Mortal Kombat.
|
|
||||||
|
|
||||||
- Bad raster effects and VRAM corruption in Super Skidmarks.
|
|
||||||
(Needs PAL timing)
|
|
||||||
|
|
||||||
- Palette problems in Sonic 2 title screen.
|
|
||||||
|
|
||||||
- Masked half of Sonic sprite visible on Sonic title screen.
|
|
||||||
|
|
||||||
- Sprite masking doesn't work in Micro Machines subscreen.
|
|
||||||
|
|
||||||
- Music has slow tempo in Batman & Robin. (doesn't seem to be a problem
|
|
||||||
with the YM2612 timers - Wonderboy 3 is normal)
|
|
||||||
|
|
||||||
- Music has jerky playback in Sonic 2, 3, 3D Blast. If you run the Z80
|
|
||||||
emulation for one scanline after requesting an interrupt, it runs fine.
|
|
||||||
|
|
||||||
- DAC and PSG output are too loud, both are divided by two for now
|
|
||||||
(though the PSG should be a bit quieter and the DAC a bit louder)
|
|
||||||
|
|
||||||
- Undead Line locks after selecting a stage, also the Z80 sound halts
|
|
||||||
after the first note is played.
|
|
||||||
|
|
||||||
This game single steps the Z80 with the following code:
|
|
||||||
|
|
||||||
