NAME
gbsplay - Gameboy sound player
SYNOPSIS
gbsplay [options] gbs-file [start-subsong [stop-subsong] ]
DESCRIPTION
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.
OPTIONS
-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.
-z Play subsongs in shuffle mode. Every subsong will be played once in random order.
-Z Play subsongs in random mode. Like shuffle mode, but a subsong can be played multiple times.
-1 Mute channel 1 on start.
-2 Mute channel 2 on start.
-3 Mute channel 3 on start.
-4 Mute channel 4 on start.
