to use the Pokemon modifier you put in your action replay. when you start the game press L and R in the menu.[the menu is ware you can save and stuff]. then open up your bag and go th items. there should be 493 heart scales or 493 master balls. you have to have the same number of heart scales or master balls as the pokemons number. after you do that walk into the tall grass and hold L when you are walking. the Pokemon should be the Pokemon you wont.
the answer written before was not good enough...here it is!pokemon heartgold-soulsilver(not sure about s.s.)94000130 fcff0000b21c4d28 00000000b0000004 0000000000000890 03e7005dd2000000 00000000Diamond-pearl:94000130 fcff0000b21c4d28 00000000b0000004 0000000000000890 03e7005dd2000000 00000000hey,they are same but..um nevermind. Oh if you have diamond-pearl
what you have to do is get the heart scale cheat, which gives you 493 heart scales, then you hold L&R and you walk and you should run into an arceus, so you look at the national dex, check what entr he is, throw away heart scales until you get to it's number, hold L&R again, and you should find it. P.S. you must walk through a patch of grass or any other place that you may run into Pokemon
I mostly use the Pokemon modifier code from my action replay The code for Diamond is: 94000130 fdff0000 b21c4d28 00000000 b0000004 00000000 94000130 feff0000 00000890 01ed0001 d0000000 00000000 da000000 00000892 dc000000 00024620 c0000000 0000000b d7000000 00000000 dc000000 00000006 d2000000 00000000 Select the code in Action Replay, then press L+R while in the game. Subtract from 493 Master Balls/Heart Scales the number it will take to get the national pokedex number of the Pokemon you want. Exit the menu and press L by itself. Walk around in tall grass and the next Pokemon you encounter should be the Pokemon whose number matches the number of remaining Master Balls/Heart Scales.
