GNUBOY FREQUENTLY ASKED QUESTIONS
|
||
|
|
|
||
|
|
|
||
|
|
Q: How do I configure gnuboy?
|
||
|
|
|
||
|
|
A: You can specify various options to gnuboy by means of "rcvars",
|
||
|
|
either on the command line or in your gnuboy.rc file. To set rcvars
|
||
|
|
from the command line, just use --varname=value, or --no-varname to
|
||
|
|
turn off yes/no options. If you wish to use a gnuboy.rc file, create
|
||
|
|
it with any text editor and save it in ~/.gnuboy (for *nix systems) or
|
||
|
|
the same directory as gnuboy.exe (for DOS/Windows systems). In this
|
||
|
|
file you can set rcvars with lines of the form "set varname value".
|
||
|
|
See the sample.rc file included for examples.

Q: Are you planning to add serial cable (gamelink) emulation?
|
||
|
|
|
||
|
|
A: Yes, read the wishlist in the README. At this time we don't have
|
||
|
|
all the technical information to emulate it 100% correctly, so if you
|
||
|
|
think you can help us find the info, get in touch.
|
||
|
|
|
||
|
|
|
||
|
|
Q: gnuboy is too slow. How can I make it run faster?
|
||
|
|
|
||
|
|
A: You can try turning the sampling rate for sound down (for example,
|
||
|
|
--samplerate=22050) or disabling sound entirely (--no-sound). Also,
|
||
|
|
running at 8bpp with --rgb565 enabled will result in the highest video
|
||
|
|
performance at the expense of some color quality. Of course, gnuboy is
|
||
|
|
very fast, and shouldn't need any performance tweaks as long as your
|
||
|
|
system is at least as fast as a Pentium/120.
|
||

|
||
|
|
Q: Why did the keybindings change in 1.0?
|
||
|
|
|
||
|
|
A: Even though lots of emulators do it, we figured it wasn't a very
|
||
|
|
good idea to use modifier keys for the controls, since some systems
|
||
|
|
may be configured to trap these for other uses. This especially became
|
||
|
|
a problem after adding support for Alt+Enter to toggle fullscreen. If
|
||
|
|
you want to go back to the old bindings and don't want to configure
|
||
|
|
them yourself, you can find all the old settings (including the old
|
||
|
|
default palette) in classic.rc. Just copy and paste to your gnuboy.rc.
|
||
|
|
|
||
|
|
|
||
|
|
Q: Will gnuboy ever support recording and playback?
|
||
|
|
|
||
|
|
A: We get this question fairly often, and I'm never sure how to answer
|
||
|
|
it. We are planning to support recording audio output before too
|
||
|
|
terribly long, but whether full demo recording and playback will ever
|
||
|
|
be supported is uncertain. We'll keep it in mind for the future,
|
||
|
|
though.
|
||
|
|
|
||
|
|
|
||
|
|
Q: Why doesn't gnuboy do anything when I run it?
|
||
|
|
|
||
|
|
A: You need to specify the name of the ROM to load on the command
|
||
|
|
line. One way to do this on Windows is to drag the ROM file onto
|
||
|
|
gnuboy.exe (or a shortcut to it). Associating *.gb and *.gbc with
|
||
|
|
gnuboy also works. Of course, you can also just use the run command on
|
||
|
|
the start menu, or open a dos prompt. Unix users of course are
|
||
|
|
expected to know how to run programs.
|
||
|
|
|
||
|
|
|
||
|
|
Q: gnuboy doesn't run on WinNT/2k!!
|
||
|
|
|
||
|
|
A: Set the following environment variables before running:
|
||
|
|
SDL_VIDEODRIVER=windib
|
||
|
|
SDL_AUDIODRIVER=waveout
|
||
|
|
Doing so should fix problems with other SDL programs too. If it still
|
||
|
|
doesn't work, let us know. Your milage may vary; some people have
|
||
|
|
reported that this doesn't help.
|
||
|
|
|
||
|
|
|
||
|
|
Q: Why is sound pitch off by about 1% in gnuboy?
|
||
|
|
|
||
|
|
A: You have a very good ear. It's a rounding issue that won't be
|
||
|
|
outright fixed for a while. If you want a workaround, set the sample
|
||
|
|
rate to a power of two (for example 32768 works well) on the command
|
||
|
|
line or in your gnuboy.rc.
|
||
|
|
|
||
|
|
|
||
|
|
Q: Why does sound have ugly static noise on Windows?
|
||
|
|
|
||
|
|
A: This is a bug in SDL's DirectSound support. Try setting the
|
||
|
|
environment variable:
|
||
|
|
SDL_AUDIODRIVER=waveout
|
||
|
|
before running gnuboy. Hopefully this won't cause any problems.
