1. I've just updated CGWatcher to allow you to select a .bat or .cmd file instead of the miner's .exe file. You can download using the same download link to get the updated files.
2. If you were to select the miner's .exe file in CGWatcher, you don't need a config file but you would need to copy the arguments from your .bat file to the Arguments textbox in CGWatcher so it to launch the miner with your settings.
Note: Some users have reported that the '2>logfile.txt' argument (or similar) will cause the miner to not work when launched from CGWatcher. I'm not sure why this is yet, but I think the method I am using to launch the miner may have a problem with the > symbol. I will look into it but for now the workaround is to use a .bat or .cmd file to specify arguments.
3. If you do use a config file, you can set the miner to scrypt mining by adding this line:
