Hi hope this makes sense as I can't find it on Google I have a ds lite with a m3 ds real card and a genuine pokemon emerald game could I somehow use the action replay option on the m3 fire red or emerald and trade pokemon over to my original emerald game?

You will need two GBAs if you want to trade with your Emerald game.

You could use action replay to set every wild Pokémon to be the same. I think you can set their moves and level as well. Just give the player a bunch of master balls and throw one at a wild pokemon. It's a cheat but it'll work.
