With action replay, but it kinda kills the fun of the game :L
Unless there is a cheat code that allows you to, NO!The only games that you can catch other Trainers' Pokémon in are the GameCube games Colosseum and XD: Gale of Darkness. Even in those, you can only catch certain Pokémon from other Trainers.
i don't know but sertch on Pokemon cheats.com
Catch trainer Pokemon
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.
If you mean another trainers Pokemon you have to use cheat codes
you don't need a cheat code you just need a master ball to catch someone else's pokemon. glad to help! emilytheanswerwizard99
