-h,--help-debug
Display additional options helpful for debugging.
-f<num>
Set audio output frequency in Hz (default: 48000).
-nf No filter emulation. This will reduce CPU overhead at the cost of reduced emulation quality.
-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.
-g<num>
Mute samples. May be used more than one time, 1 for the first SID, 2 for the second one and 3 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<num>
Select start track number (default: preset).
-o<l|s>[num]
Option 'l' will select continuous track looping while 's' will play only the current track ignoring
the others. The options can be combined and may include the track selection. The following
variations are possible: -ol<num>: will loop selected track allowing moving to another one; -os<num>:
will play selected track and then stop; -ols<num>: will loop selected track;
-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 the extension .wav appended if no extension
is given.
--au[name]
Create AU-file. The default output filename is <datafile>[n].au. Same notes as the wav file applies.
--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.
--fcurve=<num>|auto
Controls the filter curve in the ReSIDfp emulation. Ranges from 0.0 (light) to 1.0 (dark), the
default value is 0.5. If set to auto it will choose a predefined value for 6581 depending on the
tune author.
--frange=<num>|auto
If available controls the filter range for the 6581 in the ReSIDfp emulation. Ranges from 0.0
(light) to 1.0 (dark), the default value is 0.5. If set to auto it will choose a predefined value
for 6581 depending on the tune author.
-cw<w|a|s>
Set the strength (width) of combined waveforms. 'w' for weak (thin) waves, 'a' for average waves,
and 's' for strong (wide) waves.
--noaudio
Run without an audio output device.
--nosid
Run without sid emulation.
--none
Run with no audio output device and no sid emulation.
