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.
