Code:
D:Homeworld2BinReleaseHomeworld2.exe -w 1680 -h 1050
The above is exactly what is in my target line (I install games on a second partition, never to 'Program Files' ;) ) Maybe try adding (or removing) quotes? Some shortcuts have quotes around the actual target.
Like this:
Code:
"D:Homeworld2BinReleaseHomeworld2.exe" -w 1680 -h 1050
If that doesn't work, try adding the commandline switch directly to the .exe file: it should work then, no matter what shortcut you use to the game. You could run it via the Run menu, too... navigate to where the .exe is. Start -> Run -> Browse -> Homeworld2 -> Bin-> Release -> click Homeworld2.exe, then add the " -w 1280 -h 768" line to the end.
Notice the space between the - and the .exe, and the w and 1, and 0 and -, and h and 7. You need all the spaces, or it screws up. :)
