Don't know but diamond is ADAE
your action replay probobly is busted or you just are not doing it right.
You can use the Pokemon modifier for action replay but I don't know the code right now.
go to supercheats.com and search Pokemon diamond.(or pearl) you will click on the right game after you search it and there will be a list on the left side of the page. Click action replay codes and there should be a huge list of codes!!!
There is no way to get Deoxys on Pokemon diamond or pearl the only way i know is through action replay if you don't know what it is your in the right spot to find out alright here we go save up 27.00 and go to Gamestop ask the PERSON at the counter for a action replay.
at full moon island use your action replay and go directly right into the water. you will get it at another island.
U cant right now because pokemon black and white have patched action replay
A ar in Pokemon diamond and pearl is an action replay used for cheats!to loke walktrough stuff!abd get really rare Pokemon!!iv got one!but u have to put in the right codes to do it!
You can get anything with Action Replay, with the right codes that is.
go to cresselia island and use walk thru wall cheat and walk right until see a island
Well action replay is the best way to have cheat codes but if you are willing to risk your profile on the game then......cheats without action replay are called glitches and if you don't do them right your profile will be wiped out so here are some tips.USE ACTION REPLAYDONT TRY AND DO GLITCHES!!!if you want to try go to u tube and look for Pokemon pearl/diamond tweeks!!you may screw up alot of times but i got darkrai out of it!!!!!!!!!!!!!!!!!!
you need action replay and the action replay code to walk through walls. no that does not work i tried it.
First you have to get the action replay. But both action replays can ONLY connect to Pokemon Pearl, Diamond, and platinum. So if you want to connect to Soul Silver there is a place to add it. You can add all Pokemon games. So to catch trainers Pokemon you need the action replay. Then go to a trainer who you never met then he will battle you. After try to use the right ball to catch the Pokemon. Then automatically the battle will stop. That is how you catch trainer's in Diamond/Pearl/Platinum or any other. Bye for now. And your welcome for my answer.
