Just want to make a recommendation. Using "Process, Close" is not a good way to close games / emulators out. It forces close the window and the issue with that is for any emulators that might save a game's save state on exit it will not save correctly when being forced close. Even though it may not affect what you are using it for I would still recommend changing it. The better option is to use WinClose. I would change the Process, Close, game.exe part of the script to read as below:
WinClose, ahk_exe game.exe
