sidplayfp - Man Page

a C64 and SID chip emulator for playing Commodore 64 music.

Synopsis

sidplayfp [Options] datafile

Description

Sidplayfp is a music player that emulates various components from a Commodore 64 (C64) computer.  The result is a program which can load and execute C64 machine code programs which produce music and sound. Sidplayfp has been designed for accuracy which results in a quite high cpu usage.  Additional playback modes have however been provided to allow playback on low specification machines at the cost of accuracy.

Options

-h,  --help

Display help.

-h,  --help-debug

Display additional options helpful for debugging.

-f<num>

Set audio output frequency in Hz (default: 44100).

-nf

No filter emulation.  This will reduce CPU overhead at the cost of reduced emulation quality.

-o<num>

Select track number (default: preset).

-s

Stereo playback.  If the tune is identified as stereo then sid 1 and 2 become the left and right channels respectively. For three sid tunes the chips are mixed as left, center and right.

-m

Mono playback.

-v|q[level]

Verbose or quiet (no time display) console output while playing. Can include an optional level, defaults to 1.

-b<num>

Set start time in [mins:]secs[.milli] format (compatible with sid2wav).

-ds<addr>

Force dual sid environment by adding a second chip at specified address.  This forces emulation of 2 sid-chips for stereo playback even if datafile is identified as only being mono. This occurs in the case of the stereo prg format as currently there is no way to identify them.  Stereo MUS and SID files are however automatically detected.  The second sid may be installed in the 0xD420-0xD7FF or 0xDE00-0xDFFF address range.  Address may  be specified in exadecimal (e.g -ds0xd420) or decimal (e.g. -ds54304) format.

-ts<addr>

Add a third chip at specified address.  The sid may be installed in the 0xD420-0xD7FF or 0xDE00-0xDFFF address range.  Address may  be specified in exadecimal (e.g -ts0xd440) or decimal (e.g. -ts54336) format.

-u<num>

Mute a channel.  May be used more than one time.  Channel 1 to 3 are for the first SID chip while channels from 4 to 6 are for the second one and 7 to 9 for the third.

-p<num>

Set bit precision for file saving. The default is 16 to create 16 bit signed samples, but can be set to 32 (32 bit float). Other values will cause invalid output.

-o<l|s>

Option 'l' will select continuous track looping while 's' will select the current track instead of all.  This option can be combined with the track selection to form -ols<num>.

-t<num>

Set play length in [mins:]secs[.milli] format (0 is endless).

-v<n|p>[f]

Set VIC clock speed.  'n' is NTSC (America, 60Hz) and 'p' is PAL (Europe, 50Hz).  Providing an 'f' will prevent speed fixing that tries to compensate automatically for the speed difference. Removing speed fixing simulates what happens on a real C64. Options can be written as: -vnf or -vn -vf.

-m<o|n>[f]

Set SID chip model.  'o' is the old 6581 and 'n' is the new 8580. Providing an 'f' will force the selected model overriding the one specified by the tune.

--digiboost

Enable digiboost hack for 8580 model so the digi samples become audible.

-r<i|r>[f]

Set resampling mode.  'i' is interpolation (less expensive) and 'r' resampling (accurate).  Providing an 'f' will provide faster resampling sacrificing quality.  Fast resampling is available only for reSID emulation.  Options can be written as: -rif or -ri -rf.

-w,  --wav[name]

Create WAV-file.  The default output filename is <datafile>[n].wav where [n] is the tune number should there be more than one in the sid.  This allows batch conversion of sid tunes without them overwriting each other.  By providing a name it is possible to override this default behavior.  The output file will be <name> with no tune number added and <name> IS NOT checked for or appended with a legal wav file extension.

--au[name]

Create AU-file.  The default output filename is <datafile>[n].au.

--resid

Use VICE's original reSID emulation engine.

--residfp

Use reSIDfp emulation engine.

--hardsid

Use HardSID device.

--exsid

Use exSID device.

--cpu-debug

Display cpu register and assembly dumps, available only for debug builds.

--delay=[num]

Simulate c64 power on delay as number of cpu cycles. If greater than 8191 the delay will be random. This is the default.

--noaudio

Run without an audio output device.

--nosid

Run without sid emulation.

--none

Run with no audio output device and no sid emulation.

Key bindings
