This code works just fine, it's just a problem adding a single " sign 2 places
Process.Start(GamePortalPath + "\\Source\\Games\\Game1\\dosbox.exe", "-conf " + GamePortalPath + "\\Source\\Games\\Game1\\dosbox.conf");

This will Output:
D:\Source\\Games\Game1\dosbox.exe -conf D:\Source\Games\Game1\dosbox.conf

The problem comes in the progress parameter section where i needto add " infront of D:\.... and " after ...dosbox.conf like this:
D:\Source\\Games\Game1\dosbox.exe -conf "D:\Source\Games\Game1\dosbox.conf"

And this code here is just plain failure ^^ :
Process.Start(GamePortalPath + "\\Source\\Games\\Game1\\dosbox.exe", "-conf "" + GamePortalPath + "\\Source\\Games\\Game1\\dosbox.conf"");

I cannot add a single " since it will trigger a "" code to start or stop.
Is there any way to use an ascii or anything like with HTML there is "codes" like   for "space" as an example... or any other "right way" ^^ ?
