I am trying to load"other' emulators in Pinballx to allow access to games on NES, N64, commodore 64, etc, but I can't get any other emulators to work other than MAME. Every NES emulator I have tried fails at some point or another. The fceux shown below loads the executable but never the game. I have messed with the parameters but nothing seems to work. My main goal is to run pinball games but on the backglass I would like access to other systems without having to run multiple front ends. Below is a screen shot of my settings.
