Well in search of the best snes emu for ths job, I chose zsnes, but I don't use the 1.36 Wip version out there that is hacked to exit on escape. Zsnes will do this automatically if you edit the .cfg file and disable the gui. So you can use the latest stable or wip, I prever stable which is version 1.42
http://www.zsnes.com/index.php?page=filesThe line to edit is this one. Change it from 0 to 1
; GUI Disable (1 = Disable GUI, 0 = Enable GUI)
GUIDisable = 1

p.s. I am still in search of a better nes emu FCE Ultra v0.97 with escape on exit hack doesn't seem to be the most accurate nes emulator, has some graphical glitches etc...
