FarCry parameters

[EricIntruder]

In the cheats-file for Far Cry it says, add the parameter '-devmode' to the commandline.
But how do I do that:
F:\spelletjes\FarCry\Bin32\Farcry-devmode.exe : doesnt work
F:\spelletjes\FarCry\Bin32\Farcry'-devmode'.exe : doesnt work
F:\spelletjes\FarCry\Bin32\Farcry.exe'-devmode' : doesnt work
F:\spelletjes\FarCry\Bin32\Farcry.exe-devmode : doesnt work
