GNUBOY INSTALLATION
|
||||
|
||||
|
||||
*NIX SYSTEMS
|
||||
|
||||
One or more of the following is required to compile on *nix: X, SDL,
|
||||
svgalib, or Linux fbcon. Since basically everyone has X, this should
|
||||
not be a problem. Please note that the SDL and fbcon ports are the
|
||||
most functional, however. In the future, Sun console may also be
|
||||
supported.
|
||||
|
||||
The best and easiest way to build gnuboy for *nix is with the
|
||||
configure script:
|
||||
|
||||
./configure
|
||||
make
|
||||
make install
|
||||
|
||||
By default, heavy optimization and asm cpu and graphics cores will be
|
||||
used if available on your platform. For information on compiletime
|
||||
options related to performance and debugging, type:
|
||||
|
||||
./configure --help
|
||||
|
||||
Alternatively, if you don't like the GNU configure script, you may
|
||||
copy the Makefile.nix to Makefile and edit it by hand to work with
|
||||
your system. Make sure you uncomment -DIS_LITTLE_ENDIAN if your cpu is
|
||||
little endian. Please note that not everything is supported when
|
||||
compiling this way, and that it should only be done as a last resort.
|
||||
The generic Makefile.nix may be removed in the future since it's extra
|
||||
work to maintain.
|
||||
|
||||
Running make should produce the binaries xgnuboy, fbgnuboy, sgnuboy
|
||||
and/or sdlgnuboy, depending on the availability of the various
|
||||
interface libraries on your host. The install target will install
|
||||
these to $(prefix)/bin, where prefix is specified to configure in the
|
||||
usual way. The default prefix is of course /usr/local/.
|
||||
|
||||
Binary packages may be available for some platforms, but they are
|
||||
usually not quite up to date, and are not built or supported by the
|
||||
gnuboy team.
|
||||
|
||||
Binary package maintainers should be aware that, by default, gnuboy
|
||||
will be built with optimizations specific to the exact host cpu it's
|
||||
being compiled on, and may not work on older models. If you want your
|
||||
binaries to work with older systems too, run configure with the
|
||||
--disable-arch option to disable architecture specific compiler flags.
|
||||
|
||||
|
||||
WINDOWS
|
||||
|
||||
Mingw32 and the SDL development files are required to compile gnuboy
|
||||
for Windows. They may be obtained from www.mingw.org and
|
||||
www.libsdl.org, respectively.
|
||||
|
||||
Just copy Makefile.mingw32 to Makefile and run make. When done, put
|
||||
the resulting gnuboy.exe wherever you wish to install it.
|
||||
|
||||
Precompiled binaries are also available for Windows; check the site
|
||||
from which you obtained gnuboy to see if it provides copies.
|
||||
|
||||
|
||||
DOS
|
||||
|
||||
You'll need djgpp to use the included Makefile. Theoretically it
|
||||
shouldn't be hard to port the dos-specific modules to work with other
|
||||
compilers, but I see no reason why it should be necessary.
|
||||
|
||||
Since all DOS systems are basically alike, just copy Makefile.dos to
|
||||
Makefile and type "make" to compile gnuboy. No configuration should be
|
||||
necessary. If you do have build problems, let us know.
|
||||
|
||||
After compiling, place gnuboy.exe wherever you want.
|
||||
|
||||
Precompiled binaries are also available for DOS; check the site from
|
||||
which you obtained gnuboy to see if it provides copies.

GNUBOY README
|
||||
|
||||
|
||||
INTRO
|
||||
|
||||
Welcome to gnuboy, one of the few pieces of Free Software to emulate
|
||||
the Game Boy handheld game console. Written in ANSI C with a few
|
||||
optional assembler optimizations for particular cpus, gnuboy supports
|
||||
a wide range of host systems, and has been tested successfully on:
|
||||
|
||||
GNU/Linux
|
||||
FreeBSD
|
||||
OpenBSD
|
||||
BeOS
|
||||
Linux/390 (IBM S/390 Mainframe)
|
||||
SunOS/Sun Ultra60
|
||||
IRIX/SGI O2
|
||||
IRIX/SGI Indy
|
||||
AIX/Unknown
|
||||
DR-DOS
|
||||
MS-DOS
|
||||
Windows DOS box
|
||||
Windows 9x/NT/2k
|
||||
|
||||
Additionally, gnuboy should run on any other *nix variants that have
|
||||
ANSI C compilers and that are remotely POSIX compliant. As gnuboy is
|
||||
Free Software, you're welcome to fix any problems you encounter
|
||||
building it for a particular system, or to port it to entirely new
|
||||
systems.
|
||||
|
||||
|
||||
EMULATION
|
||||
|
||||
gnuboy emulates nearly all aspects of the (Color) Gameboy, including
|
||||
all of the following and much more:
|
||||
|
||||
Full GBZ80 instruction set.
|
||||
Scanline-based LCD engine.
|
||||
Ten sprites per scanline limit.
|
||||
Support for all CGB graphics extensions.
|
||||
Sprite DMA, HDMA, and GDMA.
|
||||
All four sound channels including digital samples.
|
||||
MBC1, MBC2, MBC3 (including clock), and MBC5 mappers.
|
||||
Wave pattern memory corruption when sound channel 3 is played.
|
||||
Pad, timer, divide counter, and other basic hardware registers.
|
||||
CGB double-speed CPU mode.
|
||||
|
||||
Aspects not emulated at this time include:
|
||||
|
||||
* Serial IO (link cable).
|
||||
Undocumented 'extra' ram in OAM space on Gameboy Color.
|
||||
All Super Gameboy extensions.
|
||||
* GBC, HuC1, and HuC3 IR ports.
|
||||
* Obscure mappers such as TAMA5.
|
||||
Sorting sprites by X coordinate in DMG mode.
|
||||
HALT instruction skipping in DMG mode.
|
||||
CPU stalls during HDMA and GDMA.
|
||||
|
||||
Only the two marked by * are known to affect the playability of
|
||||
actual games or demos; the rest are just listed for completeness'
|
||||
sake.
|
||||
|
||||
|
||||
FEATURES
|
||||
|
||||
In addition to basic emulation, gnuboy provides the following
|
||||
features:
|
||||
|
||||
Highly flexible keybinding and configuration subsystem.
|
||||
State saving and loading at any point.
|
||||
Very precise timing/synchronization, preserved across save/load.
|
||||
Joystick support on Linux, DOS, and all SDL-based ports.
|
||||
Fully customizable palettes for DMG games.
|
||||
Screen scaling by a factor of 2, 3, or 4 in all ports.
|
||||
Hardware-based screen scaling on platforms where it's available.
|
||||
Debug traces to stdout.
|
||||
Dynamic palette allocation when run in 256-color modes...
|
||||
OR simulated 3/3/2 bits per channel in 256-color modes.
|
||||
|
||||
For information on configuring and using these features, see the
|
||||
additional documentation in the "docs" directory.
|
||||
|
||||
|
||||
COMPATIBILITY
|
||||
|
||||
Out of over 300 results reported by testers, all games are known to
|
||||
work perfectly on gnuboy with the following exceptions:
|
||||
|
||||
Fighting Phoenix (Japanese) may or may not work since it uses the
|
||||
HuC1 memory controller, which is not implemented properly. There has
|
||||
been no report either way so far.
|
||||
|
||||
Pocket Bomberman (Japanese version, which uses HuC1) runs, but can
|
||||
be made to crash if the player jumps into the ceiling in the first
|
||||
level. It's not clear whether this bug is MBC-related, something
|
||||
else, or an actual bug in the original game.
|
||||
|
||||
Monster Go! Go! Go! (Japanese) is unplayable. The cause of the
|
||||
problem is not fully known, but it's either a very bad dump or it's
|
||||
using some sort of specialized MBC that's not documented.
|
||||
|
||||
Final Fantasy Adventure has visual problems with the fade between
|
||||
screens. Does not affect gameplay.
|
||||
|
||||
Bubble Bobble 2 has some minor tile glitches right before gameplay
|
||||
actually begins. Cause unknown. Does not affect gameplay.
|
||||
|
||||
Alone in the Dark is reported to have minor visual glitches. I
|
||||
haven't seen it myself so I can't judge their severity.
|
||||
|
||||
Both new Zelda games are reported to have a visual glitch at the
|
||||
beginning of the game, and on certain other screens. I haven't seen
|
||||
the problem myself, but supposedly it impacts gameplay to some
|
||||
extent.
|
||||
|
||||
Please report any other incompatibilities discovered directly to
|
||||
gnuboy@unix-fu.org, so that they can be documented and hopefully
|
||||
fixed.
|
||||
|
||||
|
||||
FUTURE / WISHLIST
|
||||
|
||||
Here's a brief list of what may appear in gnuboy in the future:
|
||||
|
||||
Screenshots.
|
||||
Integrated debugger.
|
||||
Super Gameboy support.
|
||||
Serial link over the internet.
|
||||
Serial link to a real Gameboy with a custom cable.
|
||||
Configurable color filters to provide more authentic LCD look.
|
||||
Custom colorization of DMG games on a per-tile basis.
|
||||
Support for more colorspaces in the hardware scaler.
|
||||
Recording audio.
|
||||
GBS player built from the same source tree.
|
||||
Full recording and playback of emulation.
|
||||
So-called "high level emulation" of certain typical dumb loops.
|
||||
|
||||
Features that are not likely to appear soon or at all include:
|
||||
|
||||
Rumble support - this would be nice, but SDL doesn't seem to support
|
||||
force-feedback yet. We'll see about it in the long-term though.
|
||||
|
||||
Eagle/2xSaI/etc. - probably not feasible since these libraries don't
|
||||
appear to be compatible with the terms of the GPL. We might work on
|
||||
our own interpolation engine eventually, but that's low priority.
|
||||
|
||||
GUI/GUI-like features - such things are best handled by external
|
||||
front-ends. We might eventually add a mechanism for external
|
||||
programs to communicate with gnuboy and reconfigure it while it's
|
||||
running, however.
|
||||
|
||||
Plugins - NO! The way I see it, plugins are just an attempt to work
|
||||
around the GPL. In any case, even if you are adding plugin support
|
||||
yourself, you are bound by the terms of the GPL when linking ANY
|
||||
code to gnuboy, including dynamic-linked modules. However we'd
|
||||
rather not deal with this mess to begin with.
|
||||
|
||||
Compressed ROMs/Saves - this one is very iffy. On most systems, this
|
||||
is redundant; *nix users can just pipe the rom through a
|
||||
decompression program, and Windows users can just double-click or
|
||||
drag files from their favorite GUI unzipper program. Linking to zlib
|
||||
isn't really acceptable since it's massively bloated and we don't
|
||||
want to include it with gnuboy or add external dependencies. We may,
|
||||
however, write our own tiny decompressor to use at some point.
|
||||
|
||||
Ideas and suggestions for other features are welcome, but won't
|
||||
necessarily be used. You're of course also free to add features
|
||||
yourself, and if they fit well into the main tree they may eventually
|
||||
get included in the official release. See the file HACKING for more
|
||||
details on modifying and/or contributing.
|
||||
|
||||
|
||||
THANKS
|
||||
|
||||
Thanks goes out to everyone who's expressed interest in gnuboy by
|
||||
writing -- users, porters, authors of other emulators, and so forth.
|
||||
Apologies if we don't get a personal response out to everyone, but
|
||||
either way, consider your feedback appreciated.
|
||||
|
||||
|
||||
EPILOGUE
|
||||
|
||||
OK, that looks like about it. More to come, stick around...
