I've read the readme, but I don't get it. I'm assuming I need this part:
-userconf
Start DOSBox with the users specific configuration file. Can be used
together with multiple -conf parameters, but -userconf will always be
loaded before them.
-conf configfilelocation
Start DOSBox with the options specified in "configfilelocation".
Multiple -conf options may be present.
See Section 13 for more details.
So I tried the latter part by going to my shortcut and using the -conf configfilelocation, replacing configfilelocation with the path to my config file in quotes. Didn't work. Now I don't know what to do.
