Wahat is action replay?

Question

i keep hearing about it when i read about pokemon stuff

Answer 1

action replay allows you to obtain more in your game. its a cheat. in pokemon you can obtain like 999x master balls and loads of rare pokemon, though u need CODES to get them, u can find action replays at about any store that sales games, like gamestop, target, fye etc...

Answer 2

Its a thing by datel that lets you get master cheats that you cant use in the game like on animal crossing you can have infinity bells or you can get your town empty of weed in the blink of an eye.
