I'm using the RASnes9x emulator (basically Snex9x with RA overlay from the RetroAchievements website) and I have a problem that is not present in the plain Snes9x emulator. I have the -fullscreen argument set in LaunchBox. The emulator launches in full screen, however the menu bar at the top of the screen is always visible. The only way to get rid of it is to hit Alt + Enter twice. Esc doesn't work as that brings up the Achievements overlay.
Anyone have an idea? This is the last step for me to have perfect integration of RASnes9x with LaunchBox.
