3DS hacking has kinda been given up, for as far as the "outsiders" are supposed to know. Action Replay for the 3DS does not exist, regardless of existing codes. There are Action Replays for DS games that are compatible with the 3DS, just no 3DS games. So yeeeaaah.
Sorry to feed the troll.
The eggs are Greninja and Yvelta. This is my all-dark team.
