Game Ex Arcade - Wheel for just Pac-Man?

[RedRedRaven]

I'm hoping to have a MAME wheel for just Pac-Man games only in GameEx Arcade. I'm thinking the proper method is to start a new emulator, then have only the Pac-Man games in their own isolated directory? Unless there is a better option (I was thinking favorites, but that just mixes everything of course).. any help is appreciated here too. Thanks.

You can do that but you will lose some of the features that are found with the integrated MAME support. But certainly doable and if you don't need the extras, it will work. Of course, you could just install only the Pac-Man ROMS and media either way  if those are the only games you will be playing.
