_argParser.
In general, arguments are read sequentially into variables and then processed in an internal inscrutable order. Duplicate arguments (e.g. --load-slot=1 --load-slot=2) will result in only the last one taking effect (slot 2 will be loaded.) The desired ROM filename should be last.
Usually, all paths can be relative (where .\ is the directory of the .exe)
Loadstate:
--load-slot=[num]
Loads the specified quicksave slot number (0-9). Overrides the configuration "AutoLoad Last Save Slot"
--load-state=[path]
Loads the specified savestate file. Overrides the configuration "AutoLoad Last Save Slot"
Config File
--config=[path]
Attempts to load a BizHawk config file from the specified path, creating a new config file at this location if it does not already exist.
Movie:
--movie=[path]
Loads specified movie
A/V Capture
--dump-type=[which]
Specifies the type of capture to be done
Valid parameters:
- vfwavi
- ffmpeg
- gif
- jmd
- nut
- imagesequence
- syncless
- wave
See File | AVI/WAV | Config and Record AVI/WAV in the main program for more details.
--dump-name=[path]
The name of the output file
--dump-length=[numframes]
The length of the capture, in frames. After this many frames have elapsed, A/V capture will automatically stop
--dump-close
If capturing and specifying a dump-length, setting this property will close the emulator after it has reached the length specified in dump-length
--dump-frames=[list_of_frames]
Controls which frames will be dumped.
list_of_frames is formatted like: 100,200,300
When this is set, overrides the --dump-length to be equal to the last frame. You could set --dump-length afterwards to pick what you want.
Ranges could be added without much trouble. Post a ticket.

--chromeless
