An AR cheat which enables a shiny Rayquaza (twilight) to appear in the Mystery Zone, which you acces by walking through walls.
He knows : Draco Meteor, Shadow Force, Roar of Time, Spacial Rend.
And has the encounter : "Apparently had an unfateful encounter at Lv. 0, Mystery Zone".
My AR fanatic friend has it and it's just damn stupid . :-<
