Emulator Cheats

Since true off-screen reload doesn't work for Invasion the Abductors (only the right edge of the screen) is it possible a cheat could trigger a gun to reload? You could then bind a hotkey to this "cheat". Some people use infinite ammo as a workaround. I use ahk so when I off-screen reload it enables and disables infinite ammo, essentially reloading the gun, but you don't get the reload sound.
