gbsplay - Gameboy sound player
gbsplay [options] gbs-file
[start-subsong [stop-subsong] ]
gbsplay emulates the sound hardware of the Nintendo Gameboy. It is
able to play the sounds from a Gameboy module dump (.GBS format) over
/dev/dsp.
- -E endian
- Set endian to endian. Valid values are b, l and
n for big, little and native endian respectively.
- -f fadeout-time
- Set fadeout time to subsong-gap seconds. Instead of cutting of the
subsong hard, do a soft fadeout. Default value is 3 seconds.
- -g subsong-gap
- Set subsong gap to subsong-gap seconds. Before playing the next
subsong after the subsong timeout, play subsong-gap seconds of
silence. Default value is 2 seconds.
- -h
- Display short help and exit.
- -l
- Enable loop mode. When the last subsong is played, playback starts again
with the first subsong. Default is no loop.
- -o plugin
- Select sound output plugin plugin. Default depends on compilation
options. Select list to view a list of all available output
plugins.
- -q
- Be quieter, reduce verbosity. Can be applied multiple times. Default
verbosity is 3.
- -r samplerate
- Set the samplerate to samplerate Hz. Default value is 44100Hz.
- -R refresh-delay
- Set the refresh delay to refresh-delay milliseconds. Default value
is 33 milliseconds. Larger values will lower CPU usage, but things as
subsong changes, fadeouts, reactions to keypresses and the on-screen
display will be delayed.
- -t subsong-timeout
- Set subsong timeout to subsong-timeout seconds. When a subsong has
been played for the given time, the player will skip to the next subsong.
A timeout of 0 seconds disables automatic subsong changes. Default value
is 120 seconds.
- -T silence-timeout
- Set silence timeout to silence-timeout seconds. When a subsong
contains silence for the given time, the player will skip to the next
subsong. Default value is 2 seconds.
- -v
- Increase verbosity, print more information. Can be applied multiple times.
Default verbosity is 3.
- -V
- Display version number and exit.

order.
