First, what game do you have? Action replay only works on ds games like pearl, diamond, and platinum.If its a gameboy game, you need a gameshark.
To get a lugia or any other pokemon, google "wild pokemon modifier" and the name of your game.
If you have pokemon platinum, then you will have to enter that game.*
First, the wild pokemon modifier. Google wpm, (wild pokemon modifier) find a good website. then get the code. the code should look something like this; 94000130 fcff0000
blahblah blahblah moremore moremore (this isnt the real code) d2000000 00000000 codes will consist of capitals A-F and numbers 0-9
I will not copy the code because some of could be incorrect.
the platinum code is 24 lines, and the pearl code is 12 lines i am not sure if the pearl code is the same as the diamond code but if u somehow have peal here it is.
94000130 FDFF0000 B21C4D28 00000000 B0000004 00000000 94000130 FEFF0000 00000890 01ED0001 D0000000 00000000 DA000000 00000892 DC000000 00024620 C0000000 0000000B D7000000 00000000 DC000000 00000000 D2000000 00000000
TO USE: press l+r to give your items slot 493 masterballs delete as many balls as you want untill you get the same number as the pokemon you want on the national dex. EX: if you want to get lugia, lugia is number 249 in the national dex, 493-249=244 if you need help use your calculator function on the poketch. when your done, press L OR R NOT BOTH or youll reset the masterballs to 493. after you press l or r walk into the tall grass and see what happens. note: if you want higher levels, go into spring path or the fight area.
- to enter a game, put the designated game into the action replay, turn it on, and it will say unknown game. look on the top left screen at the bottom left corner and you will see a code. write down the code. then go to the list of games that the action replay has. (press the green star button on the touch screen) select add new game at the top. input the name of the game and push next. then enter the code you wrote down at the main screen. you are now able to out codes in for that game.
hope this helped! :)
