How do you enter AR's?

Turn the AR on (if you don't have one you cannot do anything that follows!), then go to "management"-then add/edit game-Enter EMERALD or whatever you want to call it. Now go to add/edit codes. Enter a name for each code, followed by each series of 8 numbers/letters that were posted(usually 4 lines of 8 digits, sometimes more) from the 1st one listed down, then over to the next column. Enter each code separately, under the title you pick for it(like MASTER CODE or DMA DISABLE), but be sure to enter all of the appropriate codes to accomplish what you desire. Usually, there's a Master Code, and possibly a DMA Disable code, that MUST BE ON to use any of the other codes that were listed after it, so make sure you have all the ones you need. Once entered, go back and select the game name you used and then select the necessary codes to do whatever you're trying to do. Also, don't use more codes than what's required or too many at the same time as it may crash your game.
