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.
