Nostalgia Intellivision Emulator Escape Key

[Sparkie35]

I am having trouble mapping a different keyboard entry to exit a game/rom when in the Nostalgia Environment.  There does not seem to be a setting locally (nostalgia system), nor does the global mapping seem to work.

That said, hitting the escape key on the keyboard does indeed end the current game (and take me properly back to the rom selection wheel).

But for all other systems (emulators), I have mapped a new arcade button (which happens to send a keyboard "5") to the PC, and this works as kill/exit/end for all other emulators.

Ideas?

Solutions?

Thanks
