How do you put in action replay\ codes?

Turn your AR on and then hold A on the bar which says 'action replay' to set it as default. Go to 'select codes' on the screen that appears then and go to 'current game'. It will have a list of codes which are automatically on the action replay. You cannot turn the (M) code off because it is the master code. To add new codes, press > on the control pad and go to +ADD. Type in the name of the code on the first screen, NOT the code itself (I made that mistake once and thought for a while that I'd got the wrong device), and then go to the button which says NEXT. Then it will tell you to type in the values for the code and that's where you type the code itself (it doesn't go further in the alphabet than F so if you see any codes that go further then they're fakes). Go to Next afterwards and the code will appear on the list as what you called it. Turn it on by pressing A on the code and a little tick will appear in the box beside the code, just like on the master code.

MEW RULES!!!

You need to buy an action repaly first dude,you can enter them in the game unless you buy it from a game store.

There will be a option like saying something about adding, Go there and when that loads up there will be a section to add games, add codes and more.
