What is the action replay code in Pokemon to catch trainers?

It is not possible to catch trainers in Pokémon games, even with action replay codes. Trainers are non-capturable characters, meaning they are not programmed as Pokémon that can be caught.

Action Replay codes are used to modify game data and unlock features. While there are codes that can do things like give you unlimited items or make Pokémon super powerful, there is no code that will allow you to catch trainers.

It's important to remember that using cheats can diminish the fun of the game and may not always be compatible with all versions of the game.
