Who told you, N? But yeah, it's easy only if you understand the instructions...which are confusing to a person who doesn't the technical information.
I kinda don't like talking about it because you, Bitter, gree, Eppie, etc etc spent hundreds of hours and weeks working on getting your pokemon. To reveal the method would just be a waste of your guys' time and efforts, and I'm afraid 3rd gen pokes won't be as rare as they are and some idiot will make them fully redis. Like I have no problem talking about it to current 3rd RNGers, but I'm a little skeptical about newer ones.
