Can you catch a shiny Rayquaza in emerald without cheat?

In order to catch a shiny rayquaza in any game without cheating is to save right in front of any legendary and keep battleing it. I recommend using a masterball unless you are EXTREMMLY GOOD at catching Pokemon, It will take you about 14 hours to see one. Your chances of finding one are about 1 out of 8164. I migrated all of my good Pokemon in sapphire to platinum just to start a new game to catch a shiny kyoger, rayquaza, regice,regirock,registeel, and If you are BEOND lucky Latias(ITS YELLOW NOT RED!!!) Have good shiny legendary hunting:P!

Also if your lucky you might get a shiny latos, it's green!
