I have configured a file "happy.xml" mode quickrace, then I have to save with the button "save". when I click "load" I can load the race and then "start" to start the race.
Now I would like to start racing on the command line with parameters backups in my "happy.xml" file
when I did this "speed-dreams-2-s happy" s play stops at menu of opening.
I would like to know how to start this race in the command line.

thanks
