First question - I would have said set your show desktop to yes, which you already did. So yes, you need to configure the emulator first. Make sure you have it set to go full screen on rom load, or on emulator launch, etc. Then GameEx just launches it and inserts the rom as needed. If the emulator doesn't have a direct menu option to go full screen, you may need to tweak some things. For example; changing a setting in the emulators configure file (like an ini file or whatever), adding a command line option (like -fullscreen) or adding a keystroke in the send keys section of the configurator (like an alt+enter keystroke to make it full screen). Second question - Gen's should have an option to turn on/off the fps. Go into Gens, then Option, them Misc..., then in the second box it has FPS. Either uncheck the box that says "Enable" of tweak the color, size, transparency to your liking. Hope that helps! Welcome to the forum and have fun playing! -Han
