IIRC, I needed to specify the command line parameters for each game in daphne at the end of the cfg file - no big deal since there are only ~10.
An easy way to do it is to get each game working with the daphneloader, and have it show the commandline before starting the game. Then just cut and past that to the end of daphne.cfg.
I would be wary of using someone else's cfg files, as they are usually tailored to that person's specific setup. Might be more hassle than it's worth - and the rom and map files are easy to make (again, only about 10 games).
