-f
To load a config-file, use: 'winuae.exe -f configfile.uae'
(currently WinUAE does not check config files in:
'...\Configurations' so you have to type:
'winuae.exe -f Configurations\configfile.uae'

-s
To set/"override"/change the parameter of an specific option (inside a config file), use: 'winuae.exe -s option=parameter'.
For example: 'winuae.exe -s use_gui=no'.
The option will just be changed temporary that means the configfile itself will not be modified.

-config=
To load a config-file, use: 'winuae.exe -config= configfile.uae'

-cfgparam
To set/"override"/change the state of an specific option (inside a config file), use: 'winuae.exe -cfgparam option=parameter'.
For example: 'winuae.exe -cfgparam use_gui=no'.
Furthermore parameter(s) set with: "-cfgparam" is(are) different than '-s'.
They stay in memory and "overrides" the option(s) of all loaded configurations, even if you try to load new config from GUI.
To disable this state just restart WinUAE.

-nomultidisplay
use only primary monitor

-scsilog
enable scsi logging

-norawinput
don't try to enable rawinput (Windows XP multimouse)

-forcerdtsc
always use RDTSC (CPU internal clock counting register)

-nordtsc
never use RDTSC, use "high-resolution performance counter" instead.
(WinUAE normally selects best counter automatically)

-noaspifiltering
enable detection of all SCSI devices
(uaescsi.device normally only supports SCSI/IDE CDROMs)

-disableharddrivesafetycheck
if enabled WinUAE allows to use each harddrive which is recognized by Windows© ™ even if there is allready something installed -
for example an operating system.
If you allready removed all files and partitions and WinUAE still does not detect your "empty" drive which you want to use then this parameter is more than helpfull too.
This switch makes it possible to use "xx in 1 cardreader" and attached drives/cards (e.g.: CF II Cardflash, Microdrive, Smartmedia etc...) directly.

-rdbdump
dump the "Rigid Disk Block" of all mounted drives to file(s) called rdb_dump_x.rdb.

-log
enable logging; it is basically the same like the log-option in misc-panel
(WinUAE normally selects best counter automatically)

-help
(nothing happens)

-h
(nothing happens too)

-diskswapper=
This makes it possible to add disk image(s) to diskswapper while WinUAE starts.
'winuae.exe -diskswapper image1, image2,...'


Some examples:

If you automatically want to load a certain config and your previous safestate then enter following in command line:
'winuae -config=swiv.uae -s savestate=swiv-ready-to-play.uss'
