It is a code whose address is a position in RAM, that tells when a button on the controller is pressed.
Does every game have a Joker Command?
Yes, every game has a Joker Command, but some are non-normal and non-reverse joker commands.
What does a Joker Command do?
It is used to avoid lock-ups during the intros or varios places in the game, or when you only want to activate codes at a certain time and not constantly have the effect of the code on. It's main purpose is to activate codes with the push of a button.
Can you activate all codes from a Joker Command?
Yes. All you have to do is, put the Joker Command code in the Master Code Section. Otherwise, it will just turn on the code that is below it.
Once I have the Joker Command in, how do I use it?
Well, if you are using the Joker Command in a regular code box, not Master Code section. When you press the button/s specified by the Quantity Digits below, the value that you change the '????' to, inside of the game, it will activate the code you have put in under the Joker Command code. If it was put in the Master Code Section it would activate all codes when that button is pressed.
What if I enter a Joker Comand in Normal Code Section?
Then, enter the code that you want the Joker Command to Actiavet underneath the Joker Command code.
Example Usage
Say you wanted to use the Normal Joker Command with Infinite Health in a game. Let's say the Infinite Health code is, 8012C04C 00FF and the Joker Command is D0012822 ????. Now let's say in the game Select doesn't do anything. Then, take a look at the Quantity Digits and you will see that Selects value is 0100 for a Normal Joker Command. So you would enter the following codes, D0012822 0100, and under it 8012C04C 00FF. So now, when you are playing the game with the code on, press Select and it will refill you energy. Or if you hold Select it will give you Infinite Health. However, when you let go of Select, you no longer have Infinite Health.
