SNSF set optimizer / timer, derived from snsf9x and gsfopt.
All ripped sets should be optimized before release, to remove unused code/data unrelated to music playback.
Syntax: snsfopt [options] [-s or -l or -f or -r or -x or -t] [snsf files]
-T [time]
: Runs the emulation till no new data has been found for [time] specified.
Time is specified in mm:ss.nnn format
mm = minutes, ss = seoconds, nnn = milliseconds
-p [bytes] (default=1)
: I am paranoid, and wish to assume that any data within [bytes] bytes between two used bytes,
is also used
-P [bytes] (default=0)
: I am paranoid, and wish to assume that any trailing data within [bytes] bytes of a used byte,
is also used
-cs
: Correct header checksum before writing a ROM/SNSF.
--offset [load offset]
: Load offset of the base snsflib file.
(The option works only if the input is SNES ROM file)
-f [snsf files]
: Optimize single files, and in the process, convert minisnsfs/snsflibs to single snsf files
-l [snsf files]
: Optimize the snsflib using passed snsf files.
-r [snsf files]
: Convert to Rom files, no optimization
-x [snsf files]
: Convert to SPC files
-s [snsflib] [Hex offset] [Count]
: Optimize snsflib using a known offset/count
-t [options] [snsf files]
: Times the SNSF files. (for auto tagging, use the -T option)
Unlike psf playback, silence detection is MANDATORY
Do NOT try to evade this with an excessively long silence detect time.
(The max time is less than 2*Verify loops for silence detection)
-V [time]
: Length of verify loops at end point. (Default 20 seconds)
-L [count]
: Number of loops to time for. (Default 2, max 255)
-T
: Tag the songs with found time.
A Fade is also added if the song is not detected to be one shot.
-F [time]
: Length of looping song fade. (default 10.000)
-f [time]
: Length of one shot song postgap. (default 1.000)
-s [time]
: Time in seconds for silence detection (default 15 seconds)
Max (2*Verify loop count) seconds.
-d
: Delayed SPC capture, delay-time can be specified by -T
