I'm from the Philippines so I can't cheat, we don't have cheating devices here. ^^
I have shiny Lotad, Marril, Tentacool, and Kyogre in Pokemon Emerald, yup, I'm kinda lucky because I encountered a shiny legendary pokemon. ^^
My friend caught shiny Whismur (male and female), Poochyena, Zigzagoon, Wingull and Murkrow, also in Pokemon Emerald. He gave me those Pokemon (duplicated)
I also got a shiny Swellow by chaining in Pokeradar. ^^
