Hi. It's my first time using NEStopia. I figured out how to get Game Genie codes to work, but now what I want to know is, how do I turn a Game Genie code OFF? I have the code entered under "Temporary Codes," but even if I uncheck the box or delete the code entirely, it's still in effect when I return to the game. How do I turn it off and on at will? (There are certain parts of the game when I want the code in effect and other parts where I want to play normally.)
