Hi this is a guide as to how to use the Action Replay.

First of all, when you see the screen that says "Action Replay DS" on the Top, and on the Bottom it says "Start", and a few icons, click on the Asterist to edit, add new, select, and delete codes.

ADDING NEW CODES
This is one of the more used functions of the AR ( Action Replay ). Simply select the Asterist, then select "Add new code". You will then select the NAME, I repeat, NAME, for your code. This does not affect the code at all, just what YOU would like to call it so you remember what it does. For example, the code I have that makes all wild pokemon Adamant, I called "Adamant". Then, select continue, or in some AR's it will say Forward, on the very bottom of the bottom screen. This is where you enter the CODE this has to be EXACTLY right, or else it can fuck up your game. If a code contains XX, that is a variable representing something. You can look up what to replace XX with on google, for example, the code to make all pokemon Adamant has an XX in it, so google this: "Variables for Pokemon DP Action Replay Code Wild Pokemon Nature Modifier", or watch Disfunctions AR code compilation video and use the link in his description. Then select continue or forward after entering the code, and then you can use the code!

DELETING CODES
Highlight a codes name, and select delete ( it looks like a trash can ). Easy.

EDITING CODES
Highlight a codes name, and select the icon to the left of delete. This will allow you to change the codes name, code compilation, etc.

SELECTING CODES
Highlight a codes name, and press A.

DISELECTING CODES
Highlight a selected codes name, and press A

I will not cover ONLINE USB AR CODE INTERACTIONS, simply because I donot have a USB myself.

WARNINGS
Because of lag caused in the games internal structure during the use of a code, I dont reccamend using more then 5 codes at once. I am not saying you cannot, I am just saying I do not reccamend it.
