Configuration

First, Copy MultiMAME into a directory (I recommend NOT having it in the same directory as your emulators or your frontends.)

Run MultiMAME from the command line. This will create two XML files. *(open dos window, then type "cd \directoryyouputmultimame<enter>", then type "multimame<enter>")*

Emulators.xml - Configure your emulators - Default is one version of MAME, and one Zinc.

Filters.xml - Configure what games you want from what emulator, and in what order.

Next, modify both to the settings you want.

Then, look at the Command Line Arguments
