[REQUEST] Questions about Action Replay and copying Pokemon

[PrincessSylveon]

I'm a new member here but I have collected quite a few shinies, legendaries, BR pokes, etc. and would really like to share them with the community! Does anyone know of a legit guide online that will help me learn to use the Action Replay, and does the Action Replay even work on ORAS? I've heard of being able to copy pokes with this device, but is that still a thing??? All the guides I find online seem sketchy or don't go into enough detail. Any help or advice would be much appreciated!!
